    Introduction

    Chassis truck is mainly used to hold circuit breaker,transformer and other components in the withdrawable switchgear,chassis push and exit them. And chassis as an auxiliary operation for connecting components and busbars.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. Specific funtions are as follows: O 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 prevents misconnection and mismatched isolation contacts with load. O When the handcart is under working position or away from testing/isolating position for 10mm, the earthing switch fails to close, avoid powered falsemaking of the switch. O When the earthing switch close, the handcart shall not shift from testing/isolating to working position, avoid the switch closing the circuit breaker inmaking. O When the chassis enters into cabinet, once away from testing/isolating position, the handcart fails to draw out from the cabinet.
