Fuji Vacuum Circuit Breaker
····for Safe Operation, Easy Handling and Compactness
Vacuum circuit breakers are compact designed for safe operation,
high reliability and easy maintenance, and are widely used for
various types of high voltage circuits.
Fuji HS series vacuum circuit breakers (VCB) have been
developed through the use of our many years of successful
experience and advanced technology. They are compact and
light-mass (weight), and are available in a number of current
ratings.
Features
Compact, light-mass design
Vacuum circuit breakers have a small switching stroke as
compared with other types of circuit breakers, so their breaking
unit is small in size. To take full advantage of this feature, the
operating mechanism has been designed to reduce the size and
mass of the circuit breakers.
Spring closing system
The vacuum circuit breakers use a motor-spring stored-energy
mechanism (rapid auto-reclosing type) to provide stabilized
electrical and mechanical characteristics and to reduce the closing
operating current.

Safe operation and simplified maintenance
The excellent insulation recovery characteristics of the vacuum
interrupter allow it to react quickly from small current to shortcircuit currents, and also to exhibit a stable interrupting
performance in double earth fault and out-of-phase currents.

• The operating mechanism is mounted on the front of the frame
and the live parts are mounted on the rear. Thus, the operating
mechanism is completely isolated from the live parts (dead front
type).
• The draw-out type (Y) con be fitted with a misoperationprotection-interlock complying with the IEC and JEM standards
(available by designation).

Operating mechanism
Connection
92
The closing mechanism is simple in design and provides high
reliability. The circuit breakers use a motor-spring stored-energy
closing mechanism of the rapid auto-reclosing type.
The motor-spring operating mechanism of Fuji VCB is designed
to carry out the closing sequence using the stored-energy in the
closing spring supplied by the motor.
The operating mechanism incorporates springs capable of
storing the energy required for an OFF-ON-OFF sequence when
the breaker has been closed. The closing spring is recharged
automatically after closing. This breaker model is suitable for rapid
auto-reclosing duty. It can be used for reclosing since the charging
time for the motor mechanism is 15s or less.
Capacitor trip unit (separate mount, option)
The VCB normally employs a shunt trip
utilizing 100V DC or 200V DC.
If it is desired to use the capacitor tripping
type, connect a capacitor trip unit,
available as an optional accessory, to the
shunt trip unit.

The Fuji VCB features a dead front structure; the operating
mechanism and control circuit are mounted on the front of the
circuit breaker, and the vacuum interrupter and main circuit
terminals are on the rear to avoid accidental touching with the live
parts. These parts are enclosed in a metal cover to prevent them
from making contact with the live parts during operation.

Vacuum Interrupter
Accessories
In the vacuum interrupter, there is a pair of cup contacts, each having oblique slots.
This contact structure allows a current to flow along a winding path as shown by "1" in the
illustration below.
When the contacts open, the arc deflects in the direction shown by "2" and rotates in the
direction shown by "3".
The arc is driven round the contact surface without arc stagnation, and is extinguished in a
short time. This prevents local overheating of the contact surface and uneven wear of the
contacts, thereby providing a longer service life.
Since the contacts are made of a special material, chopping current flowing into the
contacts is reduced to 3.5A.
Service life
■ Judgement of vacuum condition
Moving contact
The vacuum condition in the vacuum
interrupter is an important factor for
operation of the VCB.
The interrupter of Fuji VCB is designed
to maintain a high vacuum for a long
period of time. It is factory tested to insure
reliable performance.
When checking the vacuum condition, use
the following procedure.
With VCB in the "open" condition, apply a
commercial frequency voltage (ex.22kV
effective value for VCB rated at 7.2kV) for
1min time across the poles of the same
phase. When the vacuum interrupter
withsatnds this voltage, the vacuum
condition is normal.

■ Mechanical life

Fixed contact
Shield
Guide
AF96-32
The VCB has a simple and excellent
operating mechanism, so the mechanical
stress developed at the time of operation
remains the constant and hence the
mechanical characteristic is kept stabilized
for many years of use. For the mechanical
life, refer to the table on pages 3 to 6.
Fuji VCB is equipped with an operating
counter for check of the mechanical life.
■ Electrical life
Function of contact structure
The electrical life of the vacuum interrupter
is determined by the switching of load as
shown in the table on pages 3 to 6. It can
be checked by observing the amount of
wear of the contacts which is indicated by
the wear indication mark (for "–N" and "
–NA" types). The indication mark can be
visually checked from the front of the VCB
(except for "–E" and "–EA" types) without
removing it from the switchgear.

Notes: ●
: Protection device is required.
–: Protection device is not required.
*1 W
hen apply the gapless arrestor, the withstand voltages (impulse) of
transformer must exceed the values listed above.
*2 W
hen interrupting a magnetizing inrush current, it is recommended
that a protection device be used.
A standard lightning arrester is sufficient.
*3 S
emiconductor device must be provided with suitable protection
devices when a semiconductor is installed on the load side of
transformer, since a surge on the low voltage side will also cause a
voltage appear on the load side, depending on the turns ratio.

When using a C-R suppressor, it may be necessary to use a
directional relay as a ground fault protection relay. Note that the
C-R suppressor may be damaged due to higher harmonics.

The high surge voltage by the VCB that injures the insulation of
the machines and apparatus is generated under certain specific
conditions. The necesstiy of surge protection depends on the
dielectric strength of the device used as a load.
The application guide given below is based on the results of
switching surge tests. When the dielectric strength of the device is
low, use of a surge absorber is recommended.
