Problems solved by technology

[0003] When the high-voltage power distribution cabinet is working, because a large number of connectors and various electronic components are installed in the power distribution cabinet, the total resistance value of the power distribution cabinet is very high, because a large amount of heat will be emitted in the case of conduction, The temperature of the power distribution cabinet suddenly increases, and the power distribution cabinet is often compact in structure, small in space and closed, especially during the peak period of use, if the power distribution cabinet cannot dissipate heat in time, it will easily lead to the inside of the power distribution cabinet. Damage to components, or even fire accidents, but if the exhaust fan is used to dissipate heat, it will consume additional energy, and the outside air will enter, especially in rainy days, the air contains a lot of moisture, which will easily cause damage to internal components
