One of the major faults of high-voltage switchgears is the insulation problem of the switchgear. The two largest influencing factors for the insulating properties of electrical equipment are humidity and temperature. Tests prove that the most easily-caused equipment insulation deterioration is a wet and hot environment when the electrical equipment is exposed to the atmosphere for a long time. Generally, it is most suitable for the electrical equipment to maintain a relative humidity of 30% to 60%, and if it exceeds 60%, the electrical equipment will be adversely affected. In an environment with excessive humidity, condensation and even water dripping are easily generated inside the high-voltage switch cabinet, so that the insulation performance of the switch cabinet is seriously damaged, and further serious accidents such as electric shock, electric arc, equipment fire and even explosion are caused. When the temperature is too high, problems such as switch tripping or abnormal operation of the equipment can be caused. When the temperature is below the "dew point", condensation occurs. The temperature of the environment of the high-voltage switch cabinet is greatly fluctuated, and moisture condensation is caused by some hygroscopic dust.
