High-voltage explosion-proof power distribution cabinet

Abstract

The invention belongs to the technical field of high-voltage power distribution cabinets, and particularly relates to a high-voltage explosion-proof power distribution cabinet, which comprises a cabinet body. Two symmetrically arranged cabinet doors are hinged to the front surface of the cabinet body. A partition plate is fixedly connected to the inner wall of the cabinet body. The interior of thecabinet body is divided into a first mounting cavity and a second mounting cavity by the partition plate. Through the arrangement of elastic telescopic mechanisms, U-shaped explosion-proof plates, fire extinguisher tank bodies, tubular spray heads, opening pressing handles, a supporting rod, an n-shaped pressing frame, a compression spring, a limiting plate, limiting blocks and L-shaped tractionframes, when explosion occurs in the cabinet body, the U-shaped explosion-proof plates on the two sides can be pushed, on one hand, the U-shaped explosion-proof plates can play a role in resisting explosive force, on the other hand, a fire extinguisher can be automatically opened through the linkage effect, fire is quickly extinguished through the tubular spray head, the problem that the generatedfire continues to burn and extends to the surrounding environment is avoided, fire disasters are avoided, and losses caused by explosion of the cabinet body are reduced.

Description

technical field [0001] The invention belongs to the technical field of high-voltage power distribution cabinets, in particular to a high-voltage explosion-proof power distribution cabinet. Background technique [0002] Explosion-proof power distribution cabinets can be divided into explosive gas environment, explosive dust environment and fire hazard environment according to the form of explosives in the environment. Explosion of electrical cabinet. [0003] There are also some technical solutions for explosion-proof power distribution cabinets in the prior art. For example, a Chinese patent with application number 201910619157.5 discloses a positive pressure type explosion-proof power distribution cabinet, including a cabinet body, a transparent observation door and an audible and visual alarm. The top of the cabinet body is fixed with an upper top plate, and the bottom of the cabinet body is equipped with a lower mounting seat, and the front side of the cabinet body is fi...

Problems solved by technology

[0005] In order to make up for the deficiencies of the existing technology, the high-voltage explosion-proof power distribution cabinet has explosion-proof performance, but when the power distribution cabinet really explodes, it can only be blocked by the power distribution cabinet shell, and the heat dissipation mechanism and other components will lose their functions. It can inhibit the control of combustion and explosion. Lack of control over the explosion situation, the explosion caused by the power distribution cabinet will cause the combustion of the line, which will ignite the surrounding combustible substances and cause the occurrence of fire.
