The KYN28-12 armored withdrawable indoor AC metal-enclosed switchgear (hereinafter referred to as switchgear) is a complete set of power distribution equipment for 3.6~12kV three-phase AC 50Hz single-busbar and single-busbar sectionalized systems. It is mainly used for power plants, power transmission from small and medium-sized generators, power distribution in industrial and mining enterprises and institutions, as well as 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
IEC298, GB3906 and DL/T404 standards. It has interlocking functions to prevent pushing or pulling the circuit breaker handcart under load, prevent incorrect opening or closing of the circuit breaker, prevent closing of the circuit breaker when the earthing switch is in the closed position, prevent accidental entry into live compartments, and prevent incorrect closing of the earthing switch when live. It can be equipped with ABB's VD4 circuit breaker or the domestic VS1 vacuum circuit breaker, making it a power distribution device with superior performance.
