internal metal armor extraction switch equipment

1.An overview The FSL–KYN28A–12 (GZSI) type indoor metal–clad extraction switch equipment (hereinafter referred to as "switching equipment") is a complete set of power distribution devices for the 3–10 kv communication 50Hz single bus and single bus segmented system. it is mainly used for power plant, small and small generator power supply, power distribution of industrial and mining enterprises, power supply of secondary substation of electric industry system and starting of large high voltage motor. Implement control protection, moni–toring, the switchgear conform to the requirements of the standard GB3906, DL404, IEC298 have prevent loading push–pull circuitbreaker handcart, prevent or circuit breaker, to prevent the earthing switch is in the closed position when the close circuit breaker avoid straying into charged across the room, avoid mistake when charged and earthing switch interlock function, as well as with VSi/vacuum circuit breaker, but also with ABB VD4 vacuum circuit brea…
