Abstract

The invention relates to an electric power cabinet structure with a ventilating pressure-reducing plate. The structure comprises a cabinet body and a ventilating plate in the cabinet body. The ventilating plate separates the inside of the cabinet body into an electrical device installation cavity and a ventilating heat dissipation cavity, and the side wall of the ventilating heat dissipation cavity is provided with ventilating slots; the ventilating plate is fixedly connected with the cabinet body by means of a frame body at the two sides, and the upper end of the ventilating plate and the inner top surface of the cabinet body are provided with ventilating top gaps; the ventilating plate comprises air-flow lead-in plates and air-flow lead-out plates, the air-flow lead-in plates are aslant arranged downwards relative to the frame body, the lead-out plates are parallel to the surface of the frame body, lead-in grooves are arranged between the lead-in plates adjacent to each other at upper positions and lower positions, and lead-out grooves are arranged between adjacent lead-out plates; the lead-out plates are also uniformly provided with ventilating holes; the lead-out plates in the ventilating heat dissipation cavity are connected with flow guide plates, and the end portions of the flow guide plates maintain convection gaps with the side wall, which is provided with the ventilating grooves, of the cabinet body; and a shielding plate fixedly connected with the outer wall of the cabinet body is arranged at the upper potions of the ventilating grooves, and the end portion of the shielding plate is inclined towards the bottom surface of the cabinet body.

Description

Technical field: [0001] The invention relates to the field of explosion-proof electrical technology, in particular to a ventilation structure of an electric cabinet. Background technique: [0002] At present, most of the power transmission and transformation facilities installed outdoors in the power system adopt a box-type structure, that is, a power box or a power cabinet. The cabinet body of the power cabinet is generally provided with a heat insulation layer to prevent sun exposure, and an air duct is provided inside, and a ventilation plate is provided at the vent of the air duct to prevent safety problems caused by untimely heat dissipation of the power facilities. The problem of the traditional power cabinet is that the air convection inside and outside the cabinet is not sufficient, especially the natural outflow of the internal hot air is not good, and the heat dissipation effect is not good. Invention content: [0003] In view of the above-mentioned shortcomings...
