summary
KZN1 (KYN28A-12) indoor metal armored mid mounted switchgear (hereinafter referred to as switchgear) is a complete set of distribution equipment for a 3-10KV three-phase AC 50HZ single busbar segmented system. Mainly used for power plants, small and medium-sized generators for power transmission, industrial and mining enterprises and institutions for power distribution, as well as for receiving and transmitting power to secondary substations in the electrical system, and for starting large high-voltage motors, for control, protection, and detection purposes. This switchgear meets the requirements of standards such as IE298 and GB3906, and has the interlocking function of preventing loaded push-pull circuit breaker handcart, preventing misunderstandings of circuit breaker opening and closing, preventing the grounding switch from closing when in the closed position, and preventing false closing of the grounding switch when in the TV. It can be paired with ABB's VD4, CE's VB2 vacuum circuit breaker from the United States, and domestic VS1 vacuum circuit breaker, making it a high-performance distribution device.
