Problems solved by technology

[0002] Due to the large amount of heat generated during the working process of power components, if the power distribution cabinet is not cooled in time, it will not only have an adverse effect on the power components, but will also cause an explosion in severe cases.
At present, the cooling of power distribution cabinets mainly adopts grilles and / or fans on the cabinet body, but such treatment will bring external dust into the cabinet body, which will adversely affect the power components. Will bring external water vapor into the cabinet, causing premature damage to power components
At present, some patent publications disclose that the power distribution cabinet adopts the method of expanding the outer wall (or extending the outer wall) to expand the heating area, so as to achieve the purpose of cooling, but this simple expansion of the space of the outer wall only expands the heating area , its cooling effect on the distribution cabinet is not very significant

Abstract

The invention relates to an explosion-proof and waterproof power distribution cabinet. The cabinet comprises a cabinet body part and an explosion-proof and waterproof part, the cabinet body part comprises a power distribution cabinet body, a power element mounting frame, support springs, power distribution cabinet support leg columns, a base and base support legs; the explosion-proof and waterproof part comprises a left side space expansion part, a right side space expansion part, a power distribution cabinet air inlet channel, a drying cavity net, a filter element film, a power distribution cabinet air outlet channel, an inclined fan, a temperature and humidity sensor and a bottom cooling plate. By specifically setting all the parts, air circulation is buffered through the space expansionparts, so that the flowing effect of internal air flow is enhanced, the cooling effect is greatly improved, and meanwhile the waterproof effect is achieved by arranging the positions of the inlet andthe outlet.

Description

technical field [0001] The invention relates to the field of electric equipment, in particular to an explosion-proof and waterproof power distribution cabinet. Background technique [0002] Since the power components will generate a lot of heat during the working process, if the power distribution cabinet is not cooled in time, it will not only have an adverse effect on the power components, but will also cause an explosion in severe cases. At present, the main method of cooling the power distribution cabinet is to install grilles and / or fans on the cabinet body, but such treatment will bring external dust into the cabinet body, which will adversely affect the power components. It will bring external water vapor into the cabinet, causing premature damage to power components. At present, some patent publications disclose that the power distribution cabinet adopts the method of expanding the outer wall (or extending the outer wall) to expand the heating area, so as to achieve...
