Description

Ventilated moisture-proof switchgear

technical field

The invention belongs to the technical field of electrical equipment, and in particular relates to a ventilation and moisture-proof switchgear.

Background technique

The switch cabinet is a kind of electrical equipment. The outside line of the switch cabinet first enters the main control switch in the cabinet, and then enters the sub-control switch. Each branch is set according to its needs. The main function of the switchgear is to open and close, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. Switchgears are almost always used in electrical equipment companies or machinery factories, and the electronic module units in the switchgear will generate a lot of heat during work, whether in winter or summer, heat will be generated, especially in the switchgear placed in the production workshop in summer, Due to the high temperature of the workshop itself, the temperature inside the switchgear rises after a period of operation. After a long period of operation, the switchgear may be damaged, the service life will be shortened, and there may be circuit hazards, fires, and personal dangers. The switchgear is placed outdoors or in an environment without adjusting temperature and humidity. When the switchgear is working in an environment with high temperature and high humidity, it is also prone to work failures. The traditional switch cabinet heat dissipation device is relatively simple, and the heat dissipation holes are directly opened on the switch cabinet body. The heat dissipation effect is poor and the heat dissipation is relatively slow. Faulty, short lifespan.
