This device is an indoor AC metal-clad withdrawable switchgear (hereinafter referred to as switchgear), which is a complete set of power distribution equipment for 3-10 kV three-phase AC 50Hz single busbar and single busbar sectionalizing systems. It is mainly used for power generation plants, power transmission from small and medium-sized generators, power distribution in industrial and mining enterprises, and power receiving, power transmission, and starting of large high-voltage motors in secondary substations of power systems. It is used for control, protection, and monitoring. This switchgear meets the requirements of standards such as DL/T404-91, IEC298, and GB3906, and has interlocking functions to prevent pushing and pulling the circuit breaker truck under load, prevent incorrect switching of the circuit breaker, prevent closing the circuit breaker when the grounding switch is closed, prevent entering the energized compartment by mistake, and prevent incorrect closing of the grounding switch when energized. It can be equipped with VS1, EV12, ZN73 vacuum circuit breakers, as well as ABB's VD4 vacuum circuit breakers. It is a power distribution device with superior performance.
