Background technique

High-voltage switchgear is a complete set of switchgear and control equipment, which serves as the power center and main power distribution device. It is mainly used for the control, monitoring, measurement and protection of power lines and main electrical equipment. It is often installed in substations, power distribution rooms, etc. The operating temperature of the high-voltage switchgear is generally between -5°C and 40°C. If the ambient temperature is too high, the conductivity of the metal will decrease, the resistance will increase, and the surface oxidation will intensify. Moreover, the high temperature will also lead to the insulation of the cabinet. The life is greatly shortened, and the insulation strength is reduced. On the contrary, if the ambient temperature is too low, internal stress will be generated in the insulation, which will eventually lead to the destruction of the insulation.
