Central Cabinet KYN28A-12/24

KYN28A-12/24 armored removable metal-enclosed switchgear (hereinafter referred to as switchgear) produced by Shenzhen Keruyue Electric Equipment Co., Ltd. is a complete set of power distribution equipment for 12kV or 24kV three-phase AC 50Hz single-bus sectionalized system. It is mainly used for power transmission of power plants, small and medium-sized generators, power distribution of industrial and mining enterprises and enterprises, as well as power collection and power transmission of the tertiary substations of the power system, as well as the starting of large high-voltage motors, to implement control protection and abuse. This switch cabinet meets the requirements of IEC289, BG3906 and other standards. It has the interlocking functions of preventing the loaded push-pull circuit breaker handcart, preventing the wrong opening and closing of the circuit breaker, preventing the closing of the circuit breaker when the grounding switch is in the closed position, preventing the wrong entry into the electrified compartment, and preventing the wrong closing of the grounding switch when the grounding switch is electrified. It can be equipped with both domestic VS1 central empty circuit breaker and ABB VD4 central vacuum circuit breaker, which is actually a distribution equipment with superior performance.

Normal Service Conditions
◎ Ambient air temperature: upper limit+40 ℃ lower limit - 10 ℃
◎ Altitude: the maximum altitude of the equipment installation site is 1000m
◎ Ambient humidity: the daily average relative humidity is not more than 95%, and the monthly average relative humidity is not more than 90%
◎ Earthquake: the seismic intensity shall not exceed 8 degrees
◎ The surrounding air shall be free from corrosive or combustible gas, water vapor and other obvious pollution
◎ No serious pollution and frequent severe vibration

Special Working Conditions
    When the switchgear operates in high temperature and/or climate with large temperature changes, there is a risk of leakage, because the heating plate in the cabinet must be put into operation to prevent insulation accidents and metal corrosion.
