Overview

The device is an indoor metal armored central switch device (hereinafter referred to as a switch device). It is a complete power distribution device of 3~12 kV, three-phase AC 50Hz single bus and single bus segmentation system. It is mainly used for power transmission, power transmission and large-scale high-voltage motor starting in power plants, small and medium-sized generators, power distribution, industrial and mining enterprises, and secondary substations of power systems. Implement control and protection. The switchgear meets the requirements of DL/T40497, Ec298GB3906, etc. It has the function of preventing the push-pull circuit breaker with load, preventing the mis-separation of the circuit breaker and preventing the grounding switch from closing the circuit breaker when it is in the closed position, preventing accidental entry into the live compartment, preventing The interlock function of the grounding switch when the power is turned on can be used with ABB's VD4 vacuum circuit breaker and VS1 vacuum circuit breaker. It is a power distribution device with superior performance.
