Design Against Internal Arc Faults
The vacuum circuit breaker adopts individual epoxy encapsulated
pole unit and a fully insulated busbar system to ensure that the
high-voltage conductors of the primary circuit are insulated and
isolated from each other, avoiding/minimizing possible occurrences
to the greatest extent.
Internal Arc Rating
The most serious potential threat for an operator is arcing fault
inside the switchgear. The metal-clad design of the ET2, with its
robust construction, has passed internal arc fault testing in all three
high-voltage compartments, with an IAC rating of up to 31.5kA-1s.
According to the standard defined protection level of switchgear
upon internal arc fault, the ET1 offer AFLR IAC class which approval
by independent third-party test.

internal protection class between compartments is IP2X.
Earthing
Every switchgear is provided with a main grounding bar which runs
through an arrangement. The copper bar’s cross-section is selected
according to the system short circuit current, which ensures a
simple and effective earthing between the switchgear and the
grounding grid of the substation.
The earthing conductors are distributed vertically and horizontally in
the panel. They are connected to the earthing switch or/and the
main earthing bar. The earthing system passes the short-circuit fault
test.
The circuit breaker truck and other function truck are connected to
the main earthing bar through the copper bar at the bottom of VCB
compartment.
There’re dedicated grounding wires to ensure reliable earthing in
the doors and low-voltage compartment.
Design Overview
Basic Interlocks
? Only when the circuit breaker compartment door is closed can
the circuit breaker be moved in or out. Only when the circuit
breaker is in the testing/isolated position can the circuit breaker
compartment door be opened.
? The trolley can only be moved from the test/isolation position to
the service position only when the circuit breaker is tripped. Vice
versa (mechanical interlock).
? Only when the VCB truck is in a complete testing or working
position can the circuit breaker be closed (mechanical interlock).
When the truck is in the testing or service position but there is no
controlled voltage, the circuit breaker cannot be closed; one can
only open it manually (mechanical electrical interlock).
? When the truck is in the service position, the control plug is
locked and hence cannot be pulled out.
? When the earthing switch is off, the truck cannot move from the
testing/isolated position to the service position; when the truck is
in the service position, the earthing switch cannot be turned
off(mechanical interlock).
? Only when the earthing switch is closed, the rear door of the
cable compartment may be opened (mechanical interlock). When
the rear door is not closed, it is impossible to turn on the earthing
switch.
Additional Interlocks
? The additional electrical or mechanical lock realizes interlocking
between the busbar earthing and the upstream incoming
/downstream outgoing breaker.
? The additional interlock may be installed onto the truck and/or
the earthing switch operation mechanism, such as the latching
electromagnet.
? Once the truck moves away, the shutters may be locked with a
padlock.
? The operation hole of the earthing switch may be locked by a
padlock.
? Additional electrical compulsory latching device may be installed
to the door of the cable compartment of the switchgear.

The busbar compartments are separated from one another
through earthed metal partition and bushings. There are separate
pressure relief channels. The whole busbar system is fully
insulated to guarantee the insulation level and to minimize the
possibility of arc fault. The bushing is installed on the stainless
steel plate to reduce the eddy current heating if necessary.
The busbar bushing is equipped with equalizing ring and shield to
optimize the local electric field, ensure reliable insulation and low
partial discharge level.
