Product Overview
KYN28A-12(GZS1) indoor metal-clad extraction type switchgear("centrally installed switchgear") is 3-12kV three-phase AC 50 Hz whole set of power distribution device with single bus and single bus sectioning system. It is mainly applied for the power transmission of power plants, small and medium generators, power distribution of mining and intrustrial enterprises and power receiving, transmission of sencondary substation of electric utility system and start of large HV motor,ect., and it is used for control ,protection and monitoring.The equipment meets requirements standards DL/T 404-2007, IEC 298 and GB 3906, ect. It has interlocking functions of preventing pull and push of Circuit Breaker handcart with load, preventing false opening and closing circuit breaker, preventing making of circuit breaker when the Earthing Switch is at the closing position,preventing entry into live cubicle and preventing mis-closing the earthing switch when the earthing is under live conditions. It can be equipped with not only VS1, V2000, VS1+Vacuum Circuit Breaker, but also VD4 vacuum circuit breaker manufactured by ABB. It is a device with superior performance.
