Heat-dissipation moisture-proof GGD type fixed low-voltage power distribution cabinet

The utility model belongs to the technical field of power distribution cabinets, and particularly relates to a heat-dissipation moisture-proof GGD type fixed low-voltage power distribution cabinet, which comprises a cabinet body and an auxiliary heat dissipation mechanism, the surfaces of the two sides of the cabinet body are respectively provided with a heat dissipation opening and a wire hole, one side of the cabinet body is in threaded connection with a rainproof mechanism, and the surface of one side of the cabinet body is connected with a connecting square pipe. According to the heat-dissipation and moisture-proof GGD type fixed low-voltage power distribution cabinet, when the weather is too hot or the temperature in the power distribution cabinet is too high, external gas enters the cold air cavities on the two sides through the flow guide cavities by means of the cross-flow fan, the gas in the cold air cavities can be cooled through the cold ends of the semiconductor coolers, and the temperature of the
