INTRODUCTION
Service Information S280-40-6 provides
the maintenance instructions for Type
VWE and VWVE three-phase, electronically controlled, vacuum reclosers.
Included is a general description of the
recloser and its operation, instructions
for periodic inspection and routine maintenance, testing procedures, and instructions for shop repairs. A service parts
list, keyed to exploded-view drawings of
the recloser is included at the back of the
manual.
Procedures for testing the recloser
and control together are found in the
control installation manual S280-75-1.
DESCRIPTION
AND OPERATION
General
The Type VWE and VWVE reclosers, are
self-controlled devices that protect distribution lines and equipment. A complete
unit consists of the recloser, a Type ME
electronic control, and an interconnecting cable. Fault current sensing is provided by the control which actuates the
recloser. Circuit interruption is provided
by the recloser.
Figure 2.
Untanked Type VWE vaccum recloser.
2
The Type VWE and VWVE reclosers
trip open on overcurrent (either phase or
ground faults) and then reclose automatically. If the overcurrent is temporary the
automatic reclose restores normal service. If the fault is permanent a preset
number of trip and reclose operations are
performed to lockout. All three phases of
the VWE and VWVE reclosers open,
reclose and lockout simultaneously
Opening sequences can all be fast, all
delayed, or any combination of fast operations followed by delayed operations up
to a total of four. Fast operations clear
temporary faults before branch-line fuses
can be damaged. Delayed operations
allow time fuses or other downline protective devices to clear so that permanent
faults can be confined to smaller sections
of line.
Arc interruption takes place within the
three sealed vacuum interrupters. Oil is
used as an insulating medium but is not
involved in arc interruption. The moving
contacts of the vacuum interrupters are
driven by the release of opening springs
that are loaded when the recloser is
closed.
Closing energy, as well as energy to
charge the opening springs, is supplied by
a high-voltage closing solenoid momentarily connected phase-to-phase through a
high-voltage contactor. The contactor is
mechanically closed by a rotary solenoid
actuated by a signal from the electronic
control.
NOTE: The closing coil of Type VWVE reclosers
below serial 1304 is connected phase to
ground. An instruction plate, mounted on the
head indicates the proper connections for the
closing coil of the particular recloser.
A trip-free, yellow operating handle located under the sleet hood will manually lock
open the recloser. It cannot manually close
the recloser but must be in the CLOSED
position for the rotary close solenoid to
operate. A red contact position indicator
linked to the recloser mechanism but independent of the operating handle is also
located under the sleed hood.
The location of the major operation components of the VWE recloser is shown in
Figure 2. They are the same for the VWVE
recloser except for the configuration of the
bushings and the rating of the vacuum
interrupter. Being aware of the location of
these components and their
S280-40-6
part in the operation of the recloser will
give a quicker and clearer understanding
of the recloser maintenance and repair
procedures that follow.

MECHANISM OPERATION
The recloser mechanism performs the
actual opening and closing of the vacuum interrupter contacts in response to
signals from the electronic control.
Contact opening is initiated by an electrical signal to a trip solenoid which acts
upon the toggle latch to release charged
opening springs. Contact closing is initated by an electrical signal to a rotary
solenoid which mechanically closes the
closing coil contactor to energize the
high voltage closing coil which closes the
vacuum interrupters and charges the
opening springs.
With the contacts closed, Figure 3, the
opening springs are fully extended and
the mechanism is in the rest (closed)
position. When the trip solenoid is energized, its push rod acts upon the toggle
latch to open the toggle and allow the
opening springs to act upon the contact
bar (Figure 4). As soon as the toggle
breaks, the contact arm assemblies are
rotated on their fixed pivots to instanteously open the interrupter contacts. I
the same motion the trip lever is rotated
to snap the toggle closed. This motion of
the reset lever also pulls the plunger out
of the closing coil. At this point the
mechansim is in the open (tripped) position (Figure 5).
A signal to the rotary solenoid closes
the contactor and energizes the high
voltage closing coil solenoid. As the
plunger is drawn down into the coil, the
reset lever is pulled down and latched,
the interrupter contacts are closed and
the closing springs are extended
(charged) figure 6). The mechanism is
then ready for another opening operation.

MAINTENANCE
Frequency of Maintenance
Because reclosers are applied under
widely varying operating and climatic
conditions, maintenance intervals are
best determined by the user based on
actual operating experience. To assure
proper operation, reclosers must be
maintained when they have operated the
equivalent of a complete duty cycle and
before the dielectric strength has deteriorated below prescribed levels. In the
absence of specific operating experience,
the following procedures are recommended.
• When Type VWE and VWVE reclosers
are operated under usual service conditions as defined in ANSI (American
National Standards Institute) C37.60,
“Standard
Requirements
for
Automatic Circuit Reclosers for
Alternating Current Systems,” it is recommended that the following maintenance procedures be performed at
the completion of an equivalent duty
cycle.
NOTE: ANSI C37.61, “Guide for the
Application, Operation and Maintenance of
Automatic Circuit Reclosers” gives a procedure for converting the standard duty
cycle, as shown on page 3 of these
instructions into an equivalent duty cycle
based on the actual operating duty of the
recloser.
• However, if the recloser has not completed an equivalent duty cycle within
three years, it is recommended that
an external inspection, oil-level check,
and a check of the dielectric strength
of the oil be made at that time. (See
steps 1, 2, and 8 of “Maintenance
Procedure” below.)
• Also it is strongly recommended that
the vacuum interrupters be replaced
after 7000 operations of the recloser.
Periodic
Maintenance Inspection
Each periodic maintenance inspection at
the completion of an equivalent duty
cycle should include at least the following:
1. Bypass and remove the recloser from
service.
A. Disconnect the control cable from
the recloser.
2. Inspect external components.
A. Check for broken or cracked bushings. Replace as necessary. (See
page 8 for procedure.)
B. Check for paint scratches and
other mechanical damage; paint
to inhibit corrosion.
C. Note counter reading and enter in
the record log in the control.
Figure 7.
Location of scribe mark on movalbe contact rod of vacuum
interrupter
3. Perform a dielectric withstand test to
check the insulation level of the recloser and the vacuum integrity of the
interrupters. (See page 7 for procedure. )
4. Lower the tank to expose the internal
components.
CAUTION
Be sure the recloser is open (yellow
operating handle inder the sleet hood
is down) before lowering the tank, so
that the mechanism will not be tripped
accidently while the mechanism is out
of oil.
A. Attach the sheaves of the tank hoisting windlass mechanism to the
recloser tank and take up the slack.
B. Remove the ten head bolts that
attach the tank to the head casting
and carefully lower the tank.
5. Clean all internal components.
A. Remove all traces of carbon by wiping with a clean, lint-free cloth.
NOTE: Although current interruption
takes place in a sealed vacuum chamber, the closing solenoid contactor operates in oil and will produce some carbon
deposits.
B. Flush the mechanism with clean
transformer oil.
CAUTION
Never use volatile solutions, detergents,
or water-soluble cleaners
6. Check the contact erosion of the
vacuum interrupters.
A. Locate the scribe mark on the moving contact rod at the top of the
interrupter, Figure 7.
B. If the scribe mark falls below the top
of the phenolic guide when the
interrupter is closed, the interrupter
has reached the end of its useful life
and must be replaced. (See page
10 for replacement procedure.)
NOTE: Procedure for manually operating
the recloser when the mechanism is out
of oil is described on page 6.
7. Check circuit components attached to
the recloser head, frame and operating
mechanism.
A. Check condition of the wiring to the
terminal strip and make sure all
connections are tight.
B. Make sure that the rotary solenoid
and the trip solenoid are fir mly
attached to the recloser frame.
C. Check that the two mercury switches are securely held in place by the
nylon mounting straps.
D. Check condition of microswitch
mounted above main shaft.
5
E. Check condition of the bushing current transformers and the associated wiring.
F. Check the control cable receptacle.
If circuit component malfunction is
suspected, see page 15 for an
operational check procedure.
8. Check the dielectric strength of the
insulating oil.
A. An oil sample taken near the bottom
of the tank should have a dielectric
strength of not less than 22 kv rms.
B. Low dielectric strength indicates the
presence of water or carbon
deposits. Replace the oil as necessary.
9. If oil must be replaced,
A. Drain the tank, and clean out all
sludge and carbon deposits.
B. Fill with new, clean insulating oil up
to 2-1/4 inches below the top of the
tank flange. Tank capacity is
approximately 53 U.S. gallons. See
Oil Condition on page 8.
10. Clean and examine the head gasket.
Replace if it is cracked, cut, or otherwise damaged, or if it has been permanently deformed.
11. Clean the head gasket seat and retank
the recloser.
A. Move the yellow operating handle
under the sleet hood to the up position to avoid any possible binding
while raising the tank.
B. Replace the head bolts and torque
to 35-55 ft-lbs. Apply clamping
force gradually and equally, in rotation, to each bolt to achieve an
evenly distributed gasket sealing
pressure.
13. Repeat the high voltage dielectric
withstand test (Step 3) to make sure
the dielectric clearances within the
tank have not been compromised.
Manual Operation
of the Recloser
The recloser may be closed and opened
manually while the mechanism is either in
or out of oil.
MECHANISM IN OIL
For a tanked recloser (mechanism
immersed in oil) use the following manual
operating procedure.
A. To close the recloser.
1. Remove the closing tool port cover
and gasket from the side of the
head casting. (See Figure 2 for
location.)
2. Insert the KA9OR T-handle closing
tool (furnished as an accessory)
into the closing tool port (Figure 8)
and engage the pin on the closing
shaft.
3. Lift up the yellow operating handle
under the sleet hood to reset the
mechanism.
4. Turn the closing tool one-quarter turn
clockwise to close the main contacts.
WARNING
Never use the KA90R closing tool to
close an energized reclsoer.
CAUTION
Forcing the closing too beyond the
mechanism stop may shear the pin on
the closing shaft.
B. To open the recloser.
1. Pull down the yellow operating handle to trip open the recloser.
MECHANISM OUT OF OIL
To operate the mechanism out of oil, proceed as follows:
A. To close the recloser.
1. If the mechanism is still mounted in
the head use the procedure for a
tanked recloser above (Mechanism
in Oil).
2. If the mechanism is removed from
the head turn the trip-reset shaft
(Figure 9) with a pair of
needlenose pliers to reset the
mechanism, then turn the closing
shaft clockwise with the closing
tool to close the main contacts.
NOTE: Type VWE reclosers below serial
1340 and VWVE reclosers below serial
1060 require the following special
thread-sealing procedure to keep moisture from entering the tank along the
threads of the head bolts.
1. Before reinstalling the head bolts,
apply a liberal amount of a nonhardening pliable sealant, Permatex FormA-Gasket No. 2, to the end of each
bolt. The four leading threads should
be completely coated.
2. When the bolt is installed, a slight
bead of material (resembling an
O-ring) should remain on the top of
the tank flange. Apply the sealant
each time the head bolts are
removed and reinstalled.
12. Check the oil level with the dipstick in
the head and adjust the level to the
upper line on the dipstick.
NOTE: If the recloser is equipped with an
oil-sight gage, the oil level should be above
the sight gage. If the oil surface line is visible in the window, add oil to raise the level
to the upper line on the dipstick.

CAUTION
The mechanism may be damaged if it is
"quick-tripped" with the yellow operating
handle while out of oil.
B. To open the recloser.
To open the contacts while the mechanism is out of oil, proceed as
follows:
1. Using the T-handle closirig tool
turn the closing shaft clockwise and
hold against the stop.
2. Release the trip lever (Figure 10) by
moving it to the right.
3. Then slowly allow the closing tool to
rotate counterclockwise to open the
main contacts.
NOTE: This procedure requires two people; one to operate the closing tool, the
other to operate the trip lever.
Insulation Level
Withstands Tests
High-potential withstand tests provide
information on the dielectric condition of
the recloser and the vacuum integrity of
the interrupters. Testing is performed at
75% of the rated low-frequency withstand voltage (37.5 kv for the VWE and
45 kv for the VWVE).
N
RADIATION
WARNING
At voltages up to 45 KV the radiation
emitted by the vacuum interrupter is
negligible. However at higher test voltages radiation injurious to personnel
may be emitted. See Radiation
Warning Service Information Bulletin
S280-90-1 for further details
Figure 9
Location of trip-reset shaft.
TEST 1: Proceed as follows:
1. Manually close main contacts of
recloser (see page 6 for procedure).
2. Ground recloser tank and head.
3. Connect all three source-side
bushings (1, 3, 5) together.
4. Apply proper test voltage to
sourceside bushings.
5. The recloser should withstand
the test voltage for 60 seconds.
TEST 2: Proceed as follows:
1. Manually close main contacts of
the recloser (see page 6 for
procedure).
2. Ground recloser tank and head.
3. Ground Phase A (bushing 2) and
Phase C (bushing 6).
4. Apply proper test voltage to
Phase B (bushing 3).
5. The recloser should withstand
the test voltage for 60 seconds.
TEST 3: proceed as follows:
1. Open main contacts of recloser
(see page 6 for procedure).
2. Ground recloser tank and head.
3. Connect and ground all three
loadside bushings (2, 4, 6).
4. Connect all three source-side
bushings (1, 3, 5).

TEST RESULTS: These high potential
withstand tests provide information on the
dielectric condition of the recloser and the
vacuum integrity of the interrupters.
A. If the recloser passes the closed-contacts tests (Tests 1 and 2) but fails the
open-contacts test (Test 3) a deteriorated vacuum in one or more of the
interrupters is most likely the cause.
Retest each vacuum interrupter individually to determine the failed phase
or phases, and replace the interrupter(s). Retest to confirm the repair.
B. If the recloser fails the closed-contacts
tests (Test 1 and 2) the cause is likely
to be a diminished electrical clearance
or a failed insulation. After correcting
the problem, retest to confirm the
repair.
Oil Condition
Oil provides the internal insulation barrier
between phases and from phase to
ground, and must be replaced before it
deteriorates below a safe dielectric level.
Replace the oil if its dielectric strength
falls below 22 kv.
New oil should always be filtered before
using even though it is obtained from an
approved source. Passing the oil through
a blotter press will remove free water and
solid contaminants such as rust, dirt, and
lint. Keep aeration to a minimum during filtering to prevent moisture in the air from
condensing in the oil and lowering its
dielectric strength.
Used oil must be treated before reusing.
Filtering may remove absorbed and free
water and other contaminants to raise the
dielectric strength to acceptable levels.
However, filtering does not always remove
water-absorbing contaminants and the
dielectric strength may fall rapidly after
being returned to service. Therefore the
recloser should be filled with new oil, or oil
that has been restored to like-new condition. Oil used in these reclosers conforms
to ASTM Standard D3487, Type l; its property limits are shown in Table 1.
SHOP MAINTENANCE
PROCEDURES
The operations described in this section
should be performed under the cleanest
conditions possible. The repair work,
except for bushing replacement, will be
simplified if the work bench is arranged so
the mechanism/head assembly can be
inverted (bushings down). No special tools
are required for any of the repair procedures.

BUSHINGS
Bushing maintenance generally consists of a thorough cleaning and a
careful examination for chips, cracks,
or other mechanical damage during
the periodic maintenance inspection.
Bushings must be replaced whenever
damage is discovered.
TYPE VWE BUSHINGS
A damages bushing can be replaced
with the recloser either tanked or
untanked, depending upon the circumstance or the damage.
• If the bushing porcelain is accidentally chipped during installation of
the recloser, an it is obvious that no
other damage has occured, the
bushing porcelain only can be
replaced without untanking the
recloser.
• If the bushings has been damaged
while in service or storage, the
recloser must be untanked. Water
or other contaminants may have
entered the tank (test the oil) the
bushing lead may be damaged
(either mechanically or electrical
flashover), or pieces of porcelain
may have fallen into the tank.
Replacing the Bushing Porcelain
with the Recloser Tanked
Refer to Figure 11 and proceed as follows:
1. Unscrew the bushing terminal and discard the terminal gasket.
2. Remove the three hex head capscrews
and clamps that secure the bushing to
the head and lift out the porcelain.
3. Remove and discard the lower bushing
gasket.
4. Twist off the split aluminum clamping ring
from the old porcelain. If it is in good
condition install it on the new porcelain;
replace with new ring if damaged.
NOTE: The clamping ring cushions and distributes the pressure between the porcelain
and the clamps. DO NOT OMIT.
5. Using a new gasket, install the new
porcelain over the bushing rod and into
the head. Make sure the roll pin on the
end of the rod is seated into the locking
groove at the top of the porcelain.
6. Position the clamping ring with the split
centered between two clamping bolts.
7. Reassemble the bushing to the head
casting with the bushing clamps. Tighten
the clamping bolts evenly, a little at a
time, to a torque of 10-15 ft-lbs
S280-40-6
NOTE: Clamping forces must be applied
gradually and equally in rotation to each
bolt. This results in an evenly distributed
gasket sealing pressure.
8. Install a new ter minal gasket and
reassemble the terminal to the bushing
rod with 35 ft-lbs of torque.
NOTE: Apply a ver y small amount of
petroleum jelly to the knurled surface of the
inside face of the terminal before assembling
the terminal to the bushing rod.
Replacing the Bushing
with the Recloser Untanked.
Refer to Figure 12 and proceed as follows:
1. Disconnect the appropriate bushing
lead from the bottom end of the bushing rod.
2. Remove the three hex head capscrews
and clamps that secure the bushing to
the head and lift out the complete
bushing assembly.
3. Remove and discard the lower bushing
gasket.
4. The complete bushing assembly can
be replaced or new porcelain only can
be installed depending upon the
extent of damage. If new porcelain
only is to be installed, proceed as follows:
A. Unscrew the bushing terminal and
withdraw the rod from the bottom
of the procelain; discard the terminal gasket.
B. Insert the rod assembly all the way
into the new porcelain, making
sure the roll pin is seated in the
locking groove in the top of the
bushing.
C. Assemble the terminal to the bushing rod using a new terminal gasket; tighten to a torque of 35 ftlbs.
NOTE: Apply a very small amount of
petroleum jelly to the knurled surface of
the inside face of the terminal before
assembling the terminal to the bushing
rod.
5. Twist off the split aluminum clamping
ring from the old bushing and install on
the new bushing if it is in good condition; replace the ring if damaged.
NOTE: The clamping ring cushions and distributes the pressure between the procelain
and the clamps. DO NOT OMIT.
6 Install the bushing assembly (new or
reworked) into the head using a new
lower bushing gasket. Position the
bushing with the stud-end of the terminal pointing outward.
7. Position the clamping ring with the split
centered between two clamping bolts.
8. Reassemble the bushing to the head
casting. Tighten the clamping bolts
evenly, a little at a time, to a torque of
10-15 ft-lbs.
NOTE: Clamping forces must be applied
gradually and equally in rotation to each
bolt. This results,in an evenly distributed
gasket sealing pressure.
9. Reconnect the lead to the bushing rod.

TYPE VWVE BUSHINGS
The bushings of the Type VWVE recloser
are oil-filled. The special fixtures and procedures required to assemble these
bushings is beyond the scope of normal
shop maintenance repair. Therefore if a
Type VWVE bushing is in any way damaged, the complete bushing assembly
must be replaced. Refer to Figure 13 and
proceed as follows:
1. Disconnect the appropriate bushing
lead from the bottom end of the bushing rod.
2. Remove the three hex head capscrews
and bushing clamps that secure the
bushing to the head casting and lift out
the complete bushing assembly.
3. Remove and discard the lower bushing
gasket.
4. Twist off the split, aluminum ring from
the old bushing and install on the new
bushing assembly if it is in good condition; replace ring if damaged.
NOTE: The clamping ring cushions and distributes the pressure between the porcelain
and the clamps. DO NOT OMIT.

5. Install the new bushing assembly into
the head using a new lower bushing
gasket. Position the bushing with the
stud-end of the terminal pointing outward.
6. Position the clamping ring with the split
centered between two clamping bolts.
7. Reassemble the bushing to the head
casting. Tighten the clamping bolts
evenly, a little at a time, to a torque of
10-15 ft-lbs.
NOTE: Clamping forces must be applied
gradually and equally, in rotation, to each
bolt. This results in an evenly distributed
gasket sealing pressure
8. Reconnect the lead to the bushing rod.
Vacuum Interrupters
Vacuum interrupters must be replaced
when:
• They lose their vacuum as evidenced by
a failure during the low frequency
dielectric withstand test across the
open contacts;
• The interrupter contacts have eroded
beyond their useful life as evidenced
by the position of the scribe mark on
the moving contact rod, or
• The interrupters have completed their
mechanical life of 7000 operations.
To replace an interrupter, refer to Figure
14 and proceed as follows:
Figure 14
Vacuum interrupter replacement.
1. Make sure the closer contacts are open,
the yellow manual operating handle
under the sleet hood is pulled down.
2. Cut the three nylon tie straps which
secure the vertical insulating barrier and
remove the barrier.
3. Loosen and remove the upper interrupter
clamp. As the clamp is loosened, atmospheric pressure on the bellows will
cause the contact rod to move down into
the interrupter. This action can be verified
by observing the scribe mark on the contact rod. It will move downward to just
above (or below) or just below the fiber
disk at the top of the interrupter.
NOTE: If the contact rod does not move, the
interrupter may have lost its vacuum or the contact rod may be sticking in the clamping fingers
of the contact operating rod assembly. Use a
screwdriver to gently spread the clamping fingers to free the rod.
4. Disconnect the bushing lead from the
lower contact plate assembly.
5. Loosen and remove the lower interrupter
clamp.
6. Remove the hardware attaching the lower
contact plate to the three ver tical
stringers and remove the contact plate
and the vacuum interrupter.
S280-40-6
7. Install a new vacuum interrupter into
the clamping fingers of the contact
operating rod and the lower contact
plate and attach the plate to the
stringers.
NOTE: On the side with the single stringer, a
spacer on the stringer stud provides a
1/16inch gap between contact plate and the
attaching flat washer and locknut when the
interrupter contacts are open. This gap is
intentional.
8. Manually close the recloser.
9. Coat the threads of the interrupter
clamps and attaching screws with a
film of transformer oil and install, but
do not tighten, the upper and lower
interrupter clamps.
10. Position the upper and lower interrupter clamps just below the shoulder
on the finger-type current exchange
connectors so that the clamping force
will be applied to the center of each as
shown in Figure 15.
11. Rotate the interrupter so that one of
the hex nuts at the top of the interrupter is centered directly beneath the
gap on one side of the upper clamp.
(See Figure 15.)
CAUTION
When rotating the interrupter avoid twisting the contact rod to prevent damaging
the bellows and destroying the interrupter.

Closing Solenoid Contactor
Type VWE reclosers below serial 3901
and Type VWVE reclosers below serial
1304 are equipped with a double pole
contactor, KA430R3, which provides a
single break in each line (Figure 16). Type
VWE reclosers, serial 3901 and above,
and Type VWVE reclosers serial 1304
and above are equipped with a double
pole contactor, KA1143R, which provides
two breaks in series in each line (Figure
17). Maintenance procedures are the
same for both contactors.
If the contacts are badly burned or
eroded, the entire contactor must be
replaced. See Figure 18 and proceed
as follows:
1. Unhook the two toggle openings
from the pin that connects the operating shaft of the contactor to the
toggle arm.
2. Remove the three C-type retaining
rings indicated in Figure 18 and
withdraw the pin.
3. Disconnect the two coil leads from
the contactor.
12. Tighten the screws of each interrupter
clamp evenly to a torque of 75 in-lbs.
NOTE: Clamps must be tight to prevent
slippage of the interrupter contact rods in
their current-exchange connectors.
13. Reconnect the bushing lead to the
lower contact plate.
14. Re-install the vertical insulation barrier
plate between the long bushing lead
and the mechanism. Position the plate
and secure it with cotton coil-tying
cord, or similar cotton lacing. Wrap the
cord snuggly at each tie point three of
four turns, knot and cut the loose
ends about 1/4 inch from the knot. A
drop of Pliobond on the loose ends
and the knot will prevent raveling. The
two ties securing the barrier to the
vertical stringer should also encircle
and secure the bushing lead.
15. Manually trip and close the recloser
several times to check interrupter
operation.
NOTE: Contact movement can be verified
by observing the movement of the scribe
mark on the upper contact rod of the interrupter. When the recloser is open the
scribe mark will be about 5/8-inch above
the fibre disk; on closing the mark will travel
1/2-inch downward.
Figure 16
KA4304R3 single break contactor.
11
NOTE: On the KA430R3 (Figure 16) contactor configuration, reattach the lockwasher and hex nut to the contactor terminal
immediately after disconnecting the coil
lead to prevent loss of moving contact
parts which are attached to the support
plate with the same hardware.
4. Disconnect the two fuse leads from the
contactor.
5. Remove three hex head capscrews
and lockwasher that attach the contactor to the underside of the recloser
mechanism frame and remove the
contactor.
6. Install the new contactor by reversing
the disassembly procedure. Use new
C-rings to secure the toggle-link pin.
7. Connect the solenoid coil leads to the
lower terminals of the KA430R3 “singlebreak” contactor or the inside terminals of the KA1 143R “double-break”
contactor.
8. Connect the fuse leads to the upper terminals of the KA430R3 or the outside
terminals of the KA1143R contactor.
9. Check Figures 16 and 17 for properlead
connections. Be sure coil and fuse
leads are positioned for maximum
clearance to other grounded parts.
Closing Solenoid
The closing solenoid coil of Type VWVE/
VWVE27 recloser below serial 1304 is
connected phase-to-ground and is rated to
operate on the system’s phase-to-neutral
voltage. It is protected with a fuse on the
hot side. The other side of the coil is
grounded by a lead connected from the
contactor to the frame. The closing
solenoid coil of type VWVE/VWVE27
reclosers serial 1304 and above, and all
Type VWE and Type VWVE38 reclosers, is
connected phase-to-phase and is rated to
operate a full system voltage. It is protected with two fuses, one on either side. A
data plate attached to the recloser head
between source side bushings 3 and 5 provides the coil connection information.
If the solenoid coil must be replaced,
due to damage or change in operating voltage, refer to Figure 19 and proceed as follows:
1. Disconnect the two coil leads from the
closing solenoid contactor.
NOTE: On the KA430R3 (Figure 16) contactor configuration, reattach the lockwashers
and nut to the contactor terminal immediately after disconnecting the coil lead to prevent
loss of parts of the moving contact arm
assembly which is attached to the support
plate with the same hardware.
Figure 17
KA1143R double-break contactor.
2. Remove the four capscrews and lockwashers which attach the base plate to
the bottom of the solenoid frame posts
and lower the coil and base plate.
3. Remove the coil from the base plate and
discard the coil gasket.
4. Using a new coil gasket, install the new
closing coil on the base plate.
NOTE: A new coil gasket is included in the
closing coil replacement kit.
5. Reassemble the base plate to the
solenoid frame posts and connect the
coil leads to the contactor terminals.
Make sure the coil leads clear the
solenoid frame by at least 1/2-inch.
6. The closing coil replacement kit includes
two new coil fuses which should be
installed with the new coil. See Closing
Solenoid Fuses on page 13 for fuse
replacement procedure.
7. The closing coil replacement kit also
includes a new voltage date plate.
Replace the plate on the sleet hood of
the recloser head if the operating voltage of the recloser is being changed.

Figure 19
Parts involved in solenoid coil replacement.
Closing Solenoid Fuses
Only one fuse (on the hot side) is used
with closing coils connected phase-toneutral. Two fuses are used with closing
coils connected phase-to-phase.
New fuses are provided with the closing
solenoid coil replacement kit and should
be installed with the replacement coil.
Fuses can also be ordered separately for
individual replacement if damaged.
A label, attached to the closing coil,
specifies the catalog number, and color
band coding of the properfuse required to
protect the coil. This information is also
listed in Table 2. Note the voltage rating is
either phase-to-phase, or phase-to-neutral
depending upon type of closing solenoid
coil connection.
To replace a closing solenoid fuse:
a. Disconnect the long fuse lead atthe
closing solenoid contactor.
b. Disconnect the lead wire from the
ter minal at the other end of
thefuse.
c. Loosen the mounting strap and slide
out the fuse.
d. Install the new fuse and reconnect
the fuse leads.

Removing Mechanism
from Head
To gain access to components located in
or on the main frame, the following procedure may be used to remove the mechanism from the head.
NOTE: These procedures will be simplified if
the untanked head and mechanism assembly
can be inverted (bushings down). The unit can
be supported on its bushings.
1. Disconnect all six bushing leads from
the rods at the ends of the bushings.
2. Disconnect the lockout lever and contact position indicator shafts by disengaging the spring loaded couplers and
locking them in the disengaged position, Figure 20.
3. If the recloser is equipped with the
auxiliary switch accessory, remove
the C or E-ring and washer, Figure
21, and disconnect the operating
lever of the switch from the recloser
mechanism.
4. If the recloser is equipped with the
CTtype batter y charger power
source, remove the screws that
secure the 0.2 mfd bathtub capacitor
to the recloser frame, Figure 22.
NOTE: The CT-type batter y charger
power source is standard on Type VWE
reclosers below serial 2100 and Type
VWVE reclosers below serial 1500. It may
be provided as an accessory on later
units.
13
5. Disconnect the seven leads connected
to the bottom of the terminal block
attached to the recloser frame, Figure
23. Be sure all leads are labeled
before removing. With the unit inverted as shown in Figure 23, the leads
are labeled A, B, C, D, E, R and N
from left to right.
6. The lead bundle is secured with a
nylon strap attached to the mechanism frame, Figure 23. Remove the
attaching screw to free the strap from
the mechanism.
7. Remove the six socket head bolts and
lockwashers that secure the frame to
the head casting and carefully lift the
mechanism from the head. Six long
pipe spacers will be released when
the mechanism is lifted.
Table 20
Couplers locked in disconnection position.
NOTE: By temporarily substituting eyebolts for two of the hex head bolts in the
bottom of the closing solenoid frame, the
mechanism can be easily lifted and handled with a hoist (Figure 24).
8. Remove the two spring-loaded couplers disengaged in Step 2 for safekeeping.
The components remaining in the head
are shown in Figure 25.

Operational Checks
An internal connection diagram of the
recloser circuits is shown in Figure 26.
The operating sequence for the various
circuit components is diagrammed in
Figure 27. These components should
provide trouble-free operation with little or
no maintenance. However, if the recloser
does not operate properly, the following
checks can be made to trouble-shoot the
recloser circuits.
NOTE: Procedures for checking, testing and
trouble shooting the electronic control are provided in a separate manual (S280-75-1)
The recloser need not be untanked to
perform these checks.
Figure 23
Connections to terminal strip attached to reclose mechanism frame.
CONTROL CABLE
Using an ohmmeter, check the continuity
between like pins and pin sockets of the
connector plugs on either end of the
electronic control cable and for discontinuity between unlike pins and pin sockets
to determine the condition of the control
cable.
NOTE: Pins or pin sockets N and P on either
plug are not connected.
Repair or replace the control cable if
defective.
CIRCUIT COMPONENTS
Figure 24
Lifting mechanism inand out of the head.
All measurements are made at the pin
sockets of the control cable receptacle on
the recloser head. A reading within + 15
percent of the specified value indicates
components are operational. Any component failing to meet the specified checks
should be replaced. Figure 28 identifies
the various circuit components.
NOTE: If the electronic control battery is used
to supply the 25 vdc power, connect as directed for only as long as necessary to perform
the specified action to prevent excessive battery drain.

2. Connect the ohmmeter to pin sockets K
and L to check the continuity of the battery charger CT winding if used.
• The meter should read approximately
1000 ohms. A zero ohms reading
indicates the 0.2 mfd capacitor may
be short-circuited. Readings deviating more than + 20% from 1000
ohms indicate a damaged resistor or
transformer winding.
Ratio Test for Sensing CT’s
1.Connect all three phases of the recloser
in series as shown in Figure 29 and close
the recloser contacts with the manual
closing tool.
2. Connect a 100 ampere a-c test current
to test points 1 and 2.
3. Energize the 100 ampere test source.
4. Using a 0-500 millimeter check the current output across socket pins K-G, K-H,
and K-J. (Figure 29A)
• The output of each CT should measure 100 ma + 10%.
Figure 28
Location of circuit components on mechanism frame.
Trip-Solenoid
1. Connect an ohmmeter between pin
sockets A and B.
• The meter should read approximately
9.5 ohms.
2. Lift up the yellow manual operating handle under the sleet hood and manually
close the recloser with the handle closing tool as described on page 6.
3. Momentarily apply 25 vdc to pin sockets
A (+) and B (-).
• The recloser should trip.
Rotary Solenoid and
Closing Solenoid Contactor
1. Connect an ohmmeter between pin
sockets E and F. The meter should read
approximately 19 ohms.
2. With the yellow manual operating handle
in the up position and the recloser contacts open, momentarily apply 25 vdc to
pin sockets F (+) and E
(-)
• The rotary solenoid should operate
producing an easily distinguishable
sound. Repeat two or three times.
3. Connect the ohmmeter across source
side B and C phase bushings, or from
source side C bushing to recloser
ground (depending upon the recloser
coil connection) and again energize the
rotary solenoid.
• The meter should indicate closing coil
continuity (read the effective dc
resistance of the closing coil) confirming that the closing solenoid contactor is closed.
4. With the rotary solenoid still energized,
manually close the recloser with the
closing tool.
18
• The ohmmeter should indicate loss
of continuity indicating that the
closing solenoid contactor has
opened.
Switches (SW1, SW2, SW3)
Table 3 shows switch for manual operating lever/recloser contact combinations.
An ohmmeter connected across the
designated pin sockets of the control
cable receptacle will indicate zero for a
closed contact and infinity for an open
contact.
CURRENT TRANSFORMERS
The current sensing transformers are
mounted on the source side bushings
underneath the head casting. The battery charger CT power source (if applicable) is mounted on the load side center bushing.
Continuity Check
1. Connect an ohmmeter, in turn, to pin
sockets K and G, K and H, and K
and J to check the continuity of the
three current sensing transformers.
• The meter should readapproximately 7 ohms, the d.c. resistance of
each winding.
NOTE: Be sure to allow for the tolerances
of meter being used. The resistance of
certain type of meters is not negligible.
Use as high a scale (lower resistance) as
is accurately readable.
5. A 100 ma reading verifies the 1000:1
ratio of the sensing CT’s. If the 100 ma
is not attained the CT winding is probably faulty.
6. De-energize the test source.
Polarity Test for Sensing CT’s
1. With the phases still connected in series
from the previous test, connect the secondaries of the CT’s in parallel by connecting pin socket G to H to J and measure the output between pin sockets K
and J as shown in Figure 29B.
2. Energize the 100 ampere a-c test
source.
A. All three transformers should have
the same polarity the output should
measure 300 ma.
B. If one transformer has its polarity
opposite of the remaining two the
output will measure 100 ma.
3. De-energize the test source and remove
the jumper wire from the receptacle.
