12kv/630A Medium Voltage with Drawable Air Insulated Metal Clad Switchgear

KYN28-12/24kV(GZS1) air-insulated metal-clad withdrawable switchgear (hereinafter as "switchgear") is a necessary indoor power distribution equipment 3-phase AC 50/60Hz. It is mainly used to receive and distribute 3-24kV net work electrical and control protection and monitoring to line circuits.

Relay chamber panel can realize the intelligent control system, with remote control, telemetry, remote communication, and remote transfer function, through the CAN communication interface with Fieldbus control network to prevent the mal-operation of a circuit breaker, to prevent pushing and pulling a handcart with load, to prevent grounding switch closed with charged, to prevent the grounding switch in the grounding position transmission and to prevent into live space, which is referred to as the "five-anti" function.

The cabinet is equipped with VS1(ZN63), ZN12 vacuum circuit breaker, and also a be equipped with an imported VD4 vacuum circuit breaker and VC series vacuum contactor. The switchgear meets the requirements of standard IEC62271-200, IEC62271-100, etc.
