KYN28-24Armoured removable AC metal-enclosed switchgear

Product Introduction：

KYN28-24 pin mounted removable AC metal time-closed switchgear is a high-voltage power distribution device specially designed for indoor 24KV, 50/60H2 two-phase power system, which is widely used in power distribution, control and protection of power plants, substations, industrial and mining enterprises and high-rise buildings. The equipment has a complete "five prevention" interlocking function, including: to prevent load shifting, to prevent the grounding switch from being accidentally closed, to prevent the live closing of the grounding switch, and to prevent the safety protection measures such as accidentally entering the live interval. The core configuration of the equipment adopts V51 and VN2 series mid-mounted vacuum circuit breakers and sealed vacuum switches with excellent performance, and is equipped with advanced and reliable secondary control and protection systems. Its structural design 1 has the following advantages---------- the bus adopts heat shrinkable insulation or epoxy overlay process, and the electrode shape is optimized and designed, 1. The cabinet layout is close and reasonable! This product integrates advanced technology, operation stability, convenient operation and safety and reliability, and is an ideal choice for 24kV power distribution system.
