Active cooling type outdoor power distribution box for state grid

Abstract

The invention discloses an active cooling type outdoor power distribution box for the state grid. The power distribution box comprises a box body, the box body is arranged on the ground, a power distribution chamber is arranged in the box body, openings are formed in the inner walls of the two sides of the power distribution chamber, ventilation nets are installed in the two openings, and a vertical cavity, an annular cavity and a mounting cavity are formed in the box body. The annular cavity is located on the outer side of the vertical cavity, and the mounting cavity is located below the vertical cavity; and a wind power triggering module comprises a rotating rod vertically arranged in the vertical cavity, and the upper end and the lower end of the rotating rod are rotationally connectedwith the inner top and the inner bottom of the vertical cavity correspondingly. The power distribution box is provided with an active heat dissipation mechanism, external wind can be converted into cold wind and then the cold wind is injected into the power distribution box body, the heat dissipation effect is extremely good, and meanwhile, an electrostatic dust collection module is further arranged to filter dust in air entering the box body, so that the dust is prevented from being attached to electrical elements.

Description

technical field [0001] The invention relates to the field of heat dissipation of distribution boxes, in particular to an active cooling type outdoor distribution box for national grid users. Background technique [0002] The distribution box is a large number of parameters in the data. It generally constitutes a low-voltage forest according to the electrical wiring. It is required to assemble switchgear, measuring instruments, protective appliances and auxiliary equipment in a closed or semi-closed metal cabinet. For the distribution box, Heat dissipation is a problem that needs to be considered. The quality of heat dissipation will directly affect the service life of the electrical components inside the distribution box. In the process of using the existing distribution box, there are the following problems: [0003] 1. The current distribution box generally adopts a passive heat dissipation method, and the heat dissipation is carried out by setting vents and ventilation ne...

AI Technical Summary

Problems solved by technology

[0003] 1. The current distribution box generally adopts a passive heat dissipation method, and the heat dissipation is carried out by setting vents and ventilation nets. The heat dissipation effect of this heat dissipation method is relatively poor;

[0004] 2. Although there are some active cooling power distribution cabinets, these active cooling power distribution cabinets only play the role of active ventilation. The wind is introduced into the power distribution cabinet, so the dust from the outside will also be brought into the cabinet. Although some power distribution cabinets have dust filters at the air inlets, a small amount of dust will still enter the cabinet. , attached to the internal electrical components, long-term dust adhesion will greatly reduce the heat dissipation of the electrical components themselves
