Problems solved by technology

[0007] In view of the problems in the above technical background, the purpose of the present invention is to provide a high-voltage power distribution cabinet with a buffering explosion-proof function, which solves the problem of poor explosion-proof impact performance and explosion-proof impact of the existing explosion-proof high-voltage power distribution cabinet proposed in the background technology. The barrier plate cannot be automatically reset and reused, the airtight gas-extinguishing environment cannot be provided after the explosion, and the incomplete buffer conversion of the gas energy generated by the explosion affects the environment.

Abstract

The invention discloses a high-voltage power distribution cabinet with buffering and explosion-proof functions. The high-voltage power distribution cabinet comprises an explosion-proof high-voltage power distribution cabinet, explosion-proof barrier plates capable of sliding towards two sides are arranged on two sides in the explosion-proof high-voltage power distribution cabinet, a plurality of groups of roller energy-absorbing and buffering structures are arranged on the outer sides of the explosion-proof barrier plates, and a power distribution cabinet base is fixedly arranged below a cabinet body. Meanwhile, explosion venting grooves are formed in the bottoms of the lower T-shaped grooves in the two sides of the power distribution cabinet middle plate and communicate with base explosion venting grooves symmetrically formed in the two sides of the power distribution cabinet base, and secondary energy absorption buffer mechanisms are installed in the base explosion venting grooves. The inner side of the side plate of the electric cabinet is fixedly provided with a plurality of groups of sealing gas injection mechanisms which are communicated with the inert gas dispersion gas channel and have gas leakage during explosion and sealing during resetting, and meanwhile, the explosion-proof high-voltage power distribution cabinet is internally provided with a linked gas fire extinguishing system, so that explosion-proof energy absorption and reutilization are realized through the structure, the fire extinguishing efficiency of the gas fire extinguishing system is also improved through automatic sealing, meanwhile, the influence of explosion on the environment is reduced, and the anti-explosion safety performance of the anti-explosion high-voltage power distribution cabinet is improved.

Description

technical field [0001] The invention relates to the technical field of high-voltage power distribution cabinets, in particular to a high-voltage power distribution cabinet with a buffer explosion-proof function. Background technique [0002] High-voltage distribution cabinets refer to electrical products that are used for on-off, control or protection in power system power generation, transmission, distribution, power conversion and consumption, with a voltage level of 3.6kV to 550kV. [0003] The three elements of explosion refer to the three conditions of heat transfer, rapidity and gas generation that constitute an explosion. For combustible gases, the three elements of an explosion are a certain concentration of combustible gas, a certain amount of oxygen, and an ignition source with enough heat to ignite the gas. [0004] The high-voltage power distribution cabinets in industrial production and special-purpose areas adopt explosion-proof power distribution cabinets whe...
