Schneider WS-G12~40.5kV Metal Enclosed Swichgear Cabinet

I. General

Characteristics

Ø  All the switch operations can be carried out only when high-voltage compartment door closed.
Ø  Reliable mechanical interlock is installed between grounding switch and vacuum circuit breaker handcart.
Ø All the parts and components installation heights meet the requirements of human engineering.
Ø  Options: Capacitive electric indicator can be used to detect feeder or bus is energized with electricity or  not.


Interlocks

Ø  Interlock meets GB3906-2006 and IEC 62 271-200 standards.
Ø  Feeder grounding switch can only be operated under re-movable part on test and removed position.
Ø  Removable part can be moved only under removable part on disconnecting status, grounding switch open and high-voltage door closed.
Ø  It can be only operated when removable part is at test, working and removed position.
Ø  High-voltage door can be opened only under removable part on test position.


Additional Safety Interlocks

Ø  Mechanical code can avoid low current switch plugging in high current switchgear by mistake.
Ø  Reliable mechanical interlock connects high-voltage compartment door and removable parts.
Ø  Options: Removable part electromagnetic interlock.
Ø  Options: Grounding switch electromagnetic interlock.
Ø  Let handcart into or out of cabinet on test position only when grounding switch is on closed position.
