KYN28 Armored removable AC metal-enclosed switchgear

This device is an indoor metal armored withdrawable switchgear (hereinafter referred to as switchgear), a complete set of power distribution devices for 3.6-12kV three-phase AC 50Hz single busbar and single busbar sectional system, mainly used in power plants, small and medium-sized Power transmission of generators, power distribution of industrial and mining enterprises, power reception and power transmission of secondary substations of electric power systems, and starting of large high-voltage motors, etc. It is used for control, protection and monitoring. This switchgear meets the requirements of IEC298.GB3906 and other standards. It can prevent the push-pull circuit breaker handcart with load, prevent the circuit breaker from being accidentally opened and closed, and prevent the grounding switch from closing the circuit breaker when the grounding switch is in the closed position. The interlock function of preventing entering the live room by mistake and preventing the grounding switch from being mistakenly closed when electrified can be equipped with either VSI vacuum circuit breaker or ABB's VD4 vacuum circuit breaker. It is a power distribution device with superior performance.
