Product Description

DPC-4-1000 withdrawable vacuum circuit breaker handcart trolley  electric chasis truck for 1000mm width switch cabinet switchgear 

Vacuum Circuit Breaker Withdrawable Chasis Truck DPC-4-1000

 

Circuit Breaker Handcart has perfect and reliable interlock function. When it combines with mid-located unit and coordinate with EK6 switch, it can meet the requirements of Five-Pretecting Interlocker in GB 3906 standard, the detail effect of handcart interlock as follow:

 

1. Used to mount circuit breaker, transformer and other components in the withdrawable switchgear, 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.

 

2. Only when the handcart is under testing/isolating or working position, the circuit breaker can make. After that,  the handcart is under locked state, which avoids false connecting or making of the spacing contact.

 

3. When the handcart is under working position or away from testing/isolating position for 10mm, the earthing switch fails to make,avoided powered false making of the switch.

 

4. When the earthing switch makes, the handcart shall not shift from testing/isolating to working position, avoiding the switch closing the circuit breaker in making.

 

5. When the chassis enters cabinet, once away from testing/isolating position, the handcart fails to draw out from the cabinet.
