I. Overview:

KYN28A-24 armored movable AC metal enclosed switchgear (hereinafter referred to as switchgear) is suitable for indoor three-phase 50/60Hz, rated voltage 24kV power systems. It is mainly used in power plants, substations, industrial and mining enterprises, and high-rise buildings to receive and distribute electrical energy, and to control, protect, and monitor circuits. The KYN28A-24 switchgear has various functions to prevent misoperation, including preventing the movement of the handcart under load, preventing the closing position of the grounding switch on the circuit breaker, preventing the live closing of the grounding switch, and preventing accidental entry into the live compartment. VS1 and VN2 series mid mounted high-voltage AC Vacuum circuit breakers and solid sealed vacuum switches with excellent performance in switchgear configuration. The secondary circuit of the switchgear is equipped with advanced and reliable control and protection components; The bus adopts heat shrinkable insulation material or epoxy coating insulation means to optimize the electrode shape. The cabinet is compact in structure. The switchgear is a power distribution equipment with advanced technology, stable performance, reasonable structure, convenient use, safety and reliability
