A fire-resistant switchgear with fluid air cooling and a sealed cabin

Abstract

The invention relates to a fireproofing switchgear cooling with fluid air and having sealed cabins. The fireproofing switchgear includes a cabinet and a plurality of independent cooling cabins detachably arranged in the cabinet; each cooling cabin includes a base, an arc-shaped cover plate which is arranged on the base, can be opened and closed, and protrudes outwards, and two baffle boards which are fixed on the base at both ends of the arc-shaped cover plate; the arc-shaped cover plate is a heat conductor having a smooth outer surface; the base, the arc-shaped cover plate, and the baffle plates enclose a sealed in-cover space; the end face of the base of the in-cover space is provided with an electrical function unit mount table for mounting an electrical function unit; long-strip shaped blowing ports are arranged in the base at the two outer sides of the arc-shaped cover plate along the boundary line of the arc-shaped cover plate and the base; and the blowing ports face the tangent direction of the boundary of the arc-shaped cover plate and the base. The fireproofing switchgear cooling with fluid air and having sealed cabins can effectively achieve cooling and waterproofing functions, the cooling energy consumption is low, the heat dissipation effect is good, and the fireproofing capability is strong.

Description

technical field [0001] The invention relates to a fireproof switchgear with a sealed cabin using fluid and air for heat dissipation, and belongs to the field of electrical equipment. Background technique [0002] The main function of the switchgear is to open and close, control and protect electrical equipment during the process of power generation, transmission, distribution and power conversion in the power system. The components in the switch cabinet are mainly composed of circuit breakers, disconnectors, load switches, operating mechanisms, transformers and various protection devices. There are many classification methods of switch cabinets. For example, according to the installation method of circuit breakers, it can be divided into removable switch cabinets and fixed switch cabinets; or according to the different cabinet structures, it can be divided into open switch cabinets, metal-enclosed switch cabinets, and metal Closed armored switchgear; according to different ...

Problems solved by technology

[0004] Because there are a large number of electrical components inside the switchgear, it is impossible to use the traditional water-cooled structure. The heat dissipation of the existing switchgear generally adopts air cooling, especially fan blowing heat dissipation or heat dissipation design of series air ducts and parallel air ducts. These heat dissipation methods It needs to be carried out around the clock, consumes a lot of energy and has low heat dissipation efficiency, and the cost is extremely high over the years; these heat dissipation methods are too noisy, and deteriorate the surrounding air quality, resulting in poor working environment and other problems; Accidents will cause combustion to the fire, accelerate the spread of the fire, reduce the practice of accident handling, and cause additional major losses
