DPC-4A-450mm VCB trolley chassis truck for handcart type VCB

Chasis truck mainly used for switch  equipment to install circuit breaker,  Transformer and other  components, push and exit it ,play  a supplementary  role in connecting the components with the busbar.

The hand-carrying Circuit breaker has two positions in the Switchgear, namely the working position and the isolated position. When the Circuit Breaker is in the working position, the main circuit of the switchgear is connected with the main circuit of the circuit breaker; and when the circuit breaker is in the isolated position, the main switchgear The circuit is disconnected from the main circuit of the circuit breaker. The switching of the two positions of the circuit breaker in the switchgear is achieved by the movement of the chassis of the hand-cranked circuit breaker. Since the main circuit is a high-voltage live accessory, the movement of the circuit breaker must be unlocked in the chassis lock device, that is, the chassis car lock device controls the chassis car to carry the circuit breaker in the switch cabinet.
