KYN28A-24 (z) series armored removable AC metal switchgear
Description:
KYN28A-24 (z) series armored removable AC metal switchgear is a power distribution equipment for 20kV three-phase AC 50 (60) Hz single bus and single bus sectional system.
It is mainly used in power plants, small and medium-sized generator power transmission, industrial and mining enterprises power distribution and secondary substation of power systems for power receiving, power transmission and large high-voltage motor starting, etc., for control protection and monitoring. It can be equipped with 6-point or 9-point on-line temperature measurement technology, which can realize remote control of the electric operation of grounding switch, electric swing in and out of circuit breaker handcart and internal fault arc protection of switch cabinet, and realize intelligent control of switch cabinet.
The switch equipment has the "five prevention" interlocking function of preventing pushing and pulling the circuit breaker handcart with load, closing the circuit breaker by mistake, closing the circuit breaker when the grounding switch is in the closed position, entering the live compartment by mistake, and closing the grounding switch by mistake when the grounding switch is live. It can be used with VS1-24 vacuum circuit breaker developed by our company, which is a kind of superior power distribution device.
This product conforms to GB3906 "3-35kv AC metal enclosed switchgear" and IEC62271-200 "rated voltage above 1kV and below 52kv AC metal enclosed switchgear and control equipment"
