KYN28A-24 Type armored removable AC metal-enclosed switchgear

SUMMARY

KYN28A-24 armored removable AC metal-enclosed switchgear (hereinafter referred to as switchgear), suitable for indoor three-phase 50/60Hz, rated voltage 24kV power system, mainly used in power plants, substations, industrial and mining In enterprises and high-rise buildings, as a means of receiving and distributing electrical energy and controlling, protecting and monitoring circuits.

The KYN28A-24 switchgear has various functions to prevent misoperation, including preventing the handcart from moving with load, preventing the grounding switch from closing the circuit breaker, preventing the grounding switch from being energized, and preventing accidental entry into the live compartment. The switchgear is equipped with VS1, VN2 series medium-mounted high-voltage AC vacuum circuit breakers and solid-sealed vacuum switches with excellent performance. The secondary circuit of the switchgear is equipped with advanced and reliable control and protection components; the busbar adopts heat-shrinkable insulation material or epoxy-coated insulation means to optimize the shape of the electrode, and the cabinet structure is compact. The switchgear is advanced in technology, stable in performance and reasonable in structure. Easy to use, safe and reliable power distribution equipment.
