Background
Combustible and explosive gases or dust are often generated in the production process of industrial departments such as petroleum, coal, textile, chemistry and the like, and the ambient air of the production units is often explosive due to the fact that the combustible and explosive gases or dust are mixed, and once the ambient air is ignited by open fire, the ambient air is subjected to severe explosion to cause serious accidents. The electric spark generated during the operation of the working electrical equipment in the environment is one of the important reasons for causing the accidents, because the external explosive gas tends to penetrate into the interior of the electrical equipment through the gap of the outer shell of the electrical equipment; the electrical equipment can be overheated in the operation process, and flammable and explosive gas can be decomposed and discharged from insulating oil or other organic insulators in the electrical equipment; in this way, once the electrical equipment generates sparks, the flammable and explosive gas inside the casing may be ignited to explode, and at the same time, the flammable and explosive gas in the external space may be detonated to cause a serious accident.
In order to avoid the occurrence of the accidents, an electric appliance working in a flammable and explosive gas environment is usually placed in a sealed explosion-proof box body so as to isolate the flammable and explosive gas from contacting the electric appliance, and the explosion-proof box body can control the explosion range in the box body once the electric appliance explodes. Therefore, the explosion-proof box must have good explosion-proof and explosion-proof properties, so that when explosion occurs in the box, the box body cannot be damaged, and thus, the box body material needs high mechanical strength, and a thick steel plate with the pressure-bearing strength of more than 0.8Mpa is adopted in common practice.
However, the structure of the existing explosion-proof box body is generally fixed, the size of the internal space cannot be adjusted, the heights of different electric appliances are different, and higher electric appliances cannot be placed in the explosion-proof box body with small space, so that the explosion-proof box body has poor applicability.
