KYN28-12 indoor metal armored withdrawable switchgear (hereinafter referred to as switchgear) is a complete set of distribution equipment for 3-12 kV three-phase AC 50HZ single busbar and single busbar segmented system. Mainly used for power plants, transmission of small and medium-sized generators, distribution of industrial and mining enterprises and institutions, and secondary substations of power systems for receiving and transmitting electricity, as well as starting large high-voltage motors. For the purpose of implementing control protection and monitoring, this switchgear meets the requirements of DL/T40491, IEC298, GB3906 and other standards. It has interlocking functions to prevent pushing and pulling circuit breakers with load, prevent accidental opening and closing of circuit breakers, prevent closing of circuit breakers when the grounding switch is in the closed position, prevent accidental entry into live compartments, and prevent accidental closing of grounding switches when live. It can be equipped with VS1 vacuum circuit breakers or ABB's VD4 vacuum circuit breakers. It is actually a high-performance power distribution device.
