Background technique

High-voltage switchgear refers to the role of on-off, control or protection in power system power generation, transmission, distribution, power conversion and consumption. High-voltage switchgear is used as electrical products with a voltage level of 3.6kV~550kV, and high-voltage isolating switches And grounding switch, high-voltage load switch, high-voltage automatic recloser and sectionalizer, high-voltage operating mechanism, high-voltage explosion-proof power distribution device and high-voltage switchgear and other major categories. The switch cabinet has functions such as overhead incoming and outgoing lines, cable incoming and outgoing lines, and bus connection. It is mainly applicable to various places such as power plants, substations, petrochemicals, metallurgical steel rolling, light industry and textiles, factories and mines, residential quarters, and high-rise buildings.

The working components in the high-voltage switchgear will generate heat when they work, which will make the temperature in the switchgear very high. If the temperature is too high, the conductivity of the metal will decrease, the resistance will increase, and the surface oxidation will intensify. The life of the insulating parts in the cabinet is greatly shortened, and the insulation strength is reduced, which easily leads to the risk of electric shock.

However, after the current cooling structure of the switchgear works for a period of time, a large amount of dust will be adsorbed on the filter components, resulting in poor cooling effect. It will affect the work of electrical equipment.
