Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an explosion-proof power distribution cabinet with an independent instrument installation room, mainly to solve the problem that the power distribution cabinet has no explosion-proof function. When a short-circuit explosion occurs in the power distribution cabinet, the generated airflow cannot If it is better discharged, it will have a greater impact on the cabinet, causing the cabinet to explode and affecting people's safety.

Abstract

The invention relates to the technical field of power distribution cabinets, and discloses an explosion-proof power distribution cabinet with an independent instrument installation room, which comprises a base, the upper surface of the base is fixedly connected with a cabinet body, the outer walls of the two sides of the cabinet body are both provided with installation plates, one side of each installation plate is fixedly connected with a fixed pipe, and the fixed pipe and the installation plate are installed at an included angle of 90 degrees. A plurality of connecting blocks are fixedly connected to one side of the fixing pipe, a plurality of limiting pipes are fixedly connected to one ends of the connecting blocks, slideways are formed in the inner walls of one sides of the fixing pipe, the connecting blocks and the limiting pipes, the slideways correspond to one another, the same sealing block is movably connected between the slideways, and a plurality of limiting blocks are fixedly connected to one side of the fixing pipe. According to the invention, when short-circuit explosion occurs in the power distribution cabinet, airflow generated by the power distribution cabinet can be rapidly discharged, so that the risk of explosion of the cabinet body caused by impact of the airflow on the cabinet body is effectively avoided, the explosion loss is reduced, and the safety of people is guaranteed.

Description

technical field [0001] The invention relates to the technical field of power distribution cabinets, in particular to an explosion-proof power distribution cabinet with an independent instrument installation room. Background technique [0002] The power distribution cabinet is the power distribution equipment used for power distribution, control, metering and cable connection in the power supply system. The interior is protected by some switches, circuit breakers, fuses, buttons, indicator lights, meters, and wires. The devices are assembled into a power distribution device that meets the design function requirements. The power distribution cabinet consumes a lot of power and generates a lot of heat. It is prone to internal overheating and cause an explosion of a line fault. In order to avoid the hazard of explosion, therefore , design an explosion-proof power distribution cabinet with an independent instrument installation room. [0003] At present, most of the existing pow...
