Description

The VCB Auxiliary Parts Chassis Truck is designed specifically for withdrawable type vacuum circuit breaker switchgear. This essential component ensures the secure mounting of circuit breakers, transformers, and other vital elements within the switchgear framework. With its advanced interlock function, the chassis truck provides enhanced operational safety by complying with the stringent requirements of the GB 3906 standard, thus guaranteeing reliable and safe performance.

The handcart’s interlock mechanism enables the following features:

• Safe mounting of circuit breakers and transformers in withdrawable switchgear.
• The circuit breaker can only operate when the handcart is in the correct position, thus preventing accidental engagement.
• Protection against unauthorized operation of the earthing switch when the handcart is not correctly positioned.
• Prevention of false connections ensuring the circuit breaker cannot close unexpectedly.
• Enhanced safety by ensuring the handcart cannot be removed from the cabinet unless appropriately isolated.

Overall, the VCB Auxiliary Parts Chassis Truck is a critical component for ensuring the safe and efficient operation of withdrawable switchgear systems.
