Closing operation
Features
During the closing operation,
the operating shaft with the
moving contact blades changes
from the “OPEN” to the
“CLOSED” position.
• Mechanical service life
The force of the springoperated mechanism ensures
a high closing speed and a
reliable connection of the main
circuit.
The good dielectric strength
of the SF6 gas provides for delayed pre-arcing onto the arcing
contacts of the fixed contacts.
Opening operation
During the opening operation,
the SF6 gas is compressed in
the arcing chamber.
The compressed gas, which
flows from the nozzles of the
moving contact blades, cools
down the breaking arc between
the contacts and safely
quenches it in a few
milliseconds.
The isolating distance established after breaking fulfills the
conditions applicable to
isolating distances in accordance
with
– IEC 60 265-1/
VDE 0670-301 * and
– IEC 60 694/
VDE 0670-1000 *
Due to the gas flow in the
arcing chamber, which is
controlled by the operating
movement, both load currents
and minor no-load currents are
safely interrupted.

Design
Mode of operation
• For switch-disconnector
In the event that an
HV HRC fuse link has
tripped, the switch is
tripped via an articulation
which is integrated into
the cover of the fuse
box (see figure).
• Requirements fulfilled as
HV alternating current
switch-fuse combination
• Selection of HV HRC fuses
for transformers
• Climate-independent and
maintenance-free, with

• Option:
“Tripped indication” of the
transformer switch for remote electrical indication
with 1 NO contact
In the event that the
fuse tripping fails, e.g.
if the fuse has been inserted incorrectly, the
fuse box is protected
by thermal protection.
The overpressure generated by overheating
trips the switch via the
silicon diaphragm in the
cover of the fuse box
and via an articulation.
This breaks the current
before the fuse box incurs
irreparable damage.

Inserting an HV HRC fuse link
The above thermal protection works independently
of the type and design of
the HV HRC fuse used.
Like the fuse itself it is
maintenance-free and independent of any outside climatic effects.
Furthermore, the Siemens
HV HRC fuses release the
striker pin depending on
the temperature and trip
the switch-disconnector as
early as in the fuse overload range. Impermissible
heating of the fuse box can
be avoided in this way.

Mode of operation
For the ready-for-service indicator, a gas-tight measurement
box is installed on the inside of
the switchgear vessel.
While changes in the gas
density during the loss of gas,
which are decisive for the
insulating capacity, are displayed, temperature-dependent changes in the gas
pressure are not. The gas in
the measurement box has the
same temperature as that in
the switchgear.
The temperature effect is
compensated via the same
pressure change in both gas
volumes.

A coupling magnet, which is

its position to an outside armature through the stainless-steel
switchgear vessel. This armature moves the ready-for-service indicator of the switchgear.

Switchgear Types 8DJ and 8DH for Secondary Distribution Systems up to 24 kV (General Part), Gas-Insulated
Standards
Standards, specifications, guidelines
fied by testing the switchgear
with rated values of shortduration power-frequency
withstand voltage and lightning impulse withstand voltage according to IEC 60 694 /
VDE 0670-1000 (see table
“Dielectric strength”).
• The rated values are referred
to sea level and to normal
atmospheric conditions
(1013 hPa, 20 °C, 11 g/m3
humidity in accordance with
IEC 60 071 / VDE 0111).
• The dielectric strength
decreases with increasing
altitude. For site altitudes
above 1000 m (above sea
level) the standards do not
provide any guidelines for
the insulation rating, but leave
this to the scope of special
arrangements.
All parts housed inside the
switchgear vessel which are
subjected to high voltage are
SF6-insulated against the
earthed enclosure.
The gas insulation at a relative
pressure of 50 kPa (= 500 hPa)
permits switchgear installation
at any desired altitude above sea
level, without the dielectric
strength being adversely affected. This also applies to the cable
connection when using cable
T-plugs or cable elbow plugs
(screened version) and to the
busbar for 8DH switchgear
(screened version).
34
Siemens HA 40.1 · 2007
Dielectric strength for
switchgear with HV HRC fuses
• When HV HRC fuses are
used, the conductors are led
out of the gas insulation
through the bushing. For
these connections in air, the
rated values (rated lightning
impulse withstand voltage,
rated short-duration
power-frequency withstand
voltage) of the dielectric
strength are referred to normal atmospheric conditions
(1013 hPa, 20 °C, 11 g/m3
humidity), hence to sea
level, in accordance with
IEC 60 071 / VDE 0111.
• Site altitude:
– As the altitude increases,
the dielectric strength in
air decreases due to the
decreasing air density. This
reduction is permitted up to
a site altitude of 1000 m
according to IEC and VDE.
– For site altitudes above
1000 m, a higher insulation
level must be selected. It
results from the multiplication
of the rated insulation level for
0 to 1000 m with the altitude
correction factor Ka.

Internal arc classification
(option)
The possibility of arc faults in
gas-insulated switchgear type
8DJ and 8DH is improbable and
a mere fraction of that typical
of earlier switchgear types, due
to:
• Use of gas-filled switchgear
compartments
• Use of suitable switching de-
vices such as three-position
switches with make-proof
earthing switch
• Logical mechanical interlocks
• Use of metal-coated voltage
transformers and three-phase
ring-core current transformers
Other features of gas-insulated
switchgear:
• There are no effects due to
external influences, such as
– Pollution layers
– Moisture
– Small animals and foreign
matter
• Maloperation is practically
excluded due to logical arrangement of the operating mechanism elements
As a “special cooling system”,
this maintenance-free pressure
absorber system reduces the
pressure-dependent and thermal effects of internal arc faults
in switchgear vessels and cable
compartments, and thus protects people and buildings.
The closed system is suitable
for both wall-standing and freestanding arrangement (only for
8DH switchgear).
Internal arcing test
• Protection of operating per-
sonnel by means of tests for
verifying the internal arc
classification
• Internal arcing tests must
be performed in accordance
with IEC 62 271-200 /
VDE 0671-200 *
Criteria for internal arc faults
• Criteria according to
IEC 62 271-200 /
VDE 0671-200 with respect
to the behaviour in case of
internal arc faults
In the unlikely event of a fault
within the switchgear vessel,
the energy conversion in the
case of an internal arc fault is
minor thanks to the gas insulation, i.e. approximately only 1/3
compared to air. The escaping
gases are discharged downwards.
Pressure absorber system
(option) for 8DJ10 **, 8DJ20 **
and 8DH10 switchgear
Optionally, the switchgear types
8DJ and 8DH can be designed
with internal arc classification:
For the use of maintenancefree and climate-independent
switchgear in substation
buildings without resistance
to internal arc faults, such as
e.g. “old substations”,the
switchgear can be designed
with a modified pressure relief
system with absorbers.
• Internal arc classification IAC
earthing by means of the
three-position switchdisconnector
In the event of an arc fault
at the cable connection,
pressure relief is effected
downwards into the cable
basement.
8DJ/8DH switchgear is completely enclosed and insensitive to
climatic influences.
• Climatic tests fulfilled in
accordance with IEC 60 932
(report)
• All medium-voltage devices
(except for HV HRC fuses) are
installed in a gas-tight, welded
stainless-steel switchgear
vessel which is filled with
SF6 gas
• Live parts outside the switch-
gear vessel are provided with
single-pole enclosure
• At no point can creepage
currents flow from highvoltage potentials to earth
• Operating mechanism parts
which are functionally important are made of corrosionproof materials
• Bearings in operating mech-
anisms are designed as drytype bearings and do not
require lubrication.
• Definitions of criteria:
– Criterion 1
Correctly secured doors and
covers do not open. Limited
deformations are accepted.
– Criterion 2
No fragmentation of the
enclosure. Projection of small
parts up to an individual mass
of 60 g, are accepted.
– Criterion 3
Arcing does not cause holes
in the accessible sides up to
a height of 2 m.
– Criterion 4
Horizontal and vertical
indicators do no ignite due to
the effect of hot gases.
– Criterion 5
