Power control switchboard device screen

Abstract

A power control switchboard device screen is used for solving the problems of water prevention, dust prevention and cooling of the power control switchboard device screen. A cabinet door is arranged at a front side of a cabinet body, a lock assembly is arranged at an inner side of the cabinet door, four cabinet door sealing strips are arranged at the inner side of the cabinet door and encircle to form a square structure, four cabinet body sealing strips are arranged at an inner side of the cabinet door and encircle to form a square structure, contact surfaces of the cabinet door sealing strips and the cabinet body sealing strips are inclined surfaces, a top cover is arranged at the top of the cabinet body, a rubber strip is arranged between the top cover and the cabinet body, an exhaust fan is arranged at the bottom of the top cover, an air outlet of the exhaust fan is connected with an air transmission pipe, a screen seat is arranged at the top of the top cover, an installation block is arranged at the bottom of the screen seat and is connected with the air transmission pipe, a mesh layer and a spongy layer are arranged at an inner side of the screen seat and are vertically arranged, a rain cover is arranged at the top of the top cover, and a cooling mechanism is arranged at an inner side of the rain cover. By the power control switchboard device screen, water prevention, dust prevention and cooling of the power control switchboard device screen can be effectively achieved.

Description

technical field [0001] The invention relates to the technical field of power system equipment, in particular to an equipment screen of a power control switchboard. Background technique [0002] The equipment screen of the power control switchboard has built-in high-voltage circuit breakers, high-voltage switches and other power components, which are often invaded by rainwater when placed outdoors. When water enters the equipment screen of the power control switchboard, the components in the equipment screen of the power control switchboard will be soaked in water , resulting in a short circuit of the electrical equipment and failure to operate normally. In order to solve the rainwater dripping from the top of the equipment screen of the power control switchboard, the whole body of the equipment screen of the power control switchboard is designed as a closed structure in the prior art. Although the problem of waterproofing is solved to a certain extent, it causes the equipmen...

AI Technical Summary

Problems solved by technology

In order to solve the heat dissipation problem, in the prior art, the method of blowing air into the equipment screen of the power control switchboard is adopted to dissipate heat through the flow of air, but in this way, it is easy to bring in dust from the outside of the equipment screen of the power control switchboard. Scattered on the components inside the cabinet, reducing the service life of the components
