Circuit Breaker chassis Truck for withdrawable switchgear :
Chassis truck is mainly used to holding circuit breaker, transformer and other components in the withdrawable swi t c h g e ar, as auxiliary operation of components with busbar.
When operation with internal mechanism of circuit breaker and other interlock mechanism of mid-placed cabinet, it can
satisfy the interlock requirement of "5 preventions" stipulated in GB3906.
Only when the handcart is under testing/isolating or working position, the circuit breaker can be closed. After that, the handcart is underlocked state,which avoids false connecting or making of the spacing contact.
When the handcart is under working position or away from testing/isolating position for 10mm, the earthing switch fails to close, avoid powered false making of the switch.
When the earthing switch close, the handcart shall not shift from testing/isolating to working position, avoid the switch closing the circuit breaker in making.
When the chassis enters into cabinet, once away from testing/isolating position, the handcart fails to draw out from the cabinet.
