Vacuum Circuit Breaker Chassis Truck for Switchgear Vs1 Truck

Product Description

Product Description

Chassis trucks are mainly used to carry components such as circuit breakers and transformers in the withdrawable switchgear, and to push them in and push them out as auxiliary operations for connecting components and busbars. When the chassis truck works with the internal mechanism of the circuit breaker and other interlocks in the mid-set cabinet, it can meet the "five prevention" interlock requirements in GB3906.

The circuit bredker can be closed only when then hand trolley is at test isolation or working position.After the breaker is closed,the hand trolley is under latching status so as to prevent misconnection with load and mis-closing contact when the hand trolley is in the working position or about 10mm  away from the test/isolation position,the grounding switch can't be closed,so as to prevent misconnection of switch with load.
when the grounding switch is closde ,the hand trolley can't move from the test/isolation position towards the working position ,so as to prevent the grounding switch closing the breaker when closing.After the hand trolley entered the switchgear,it can't be withdrew once upon leaving the test/isolation position.
