Explosion-proof tank for electric appliance

Abstract

The invention relates to an explosion-proof tank for an electric appliance, which comprises a sealed tank body, wherein the electric appliance needing explosion prevention is arranged in the tank body, and safety gas is filled into the tank body. In the explosion-proof tank for an electric appliance, the electric appliance in the tank body is arranged in a safety environment without causing explosion for electric sparks because the safety gas is filled into the tank body, and the explosion-proof effect can be achieved without very high mechanical strength of the material of the tank body, so that various light materials can be adopted as the tank body, and the processing difficulty is smaller. Compared with the traditional technical scheme, the explosion-proof tank for an electric appliance has the advantages of light weight, convenient transportation, low manufacturing cost and the like.

Description

technical field [0001] The invention relates to a casing of electric equipment, in particular to a sealed electric explosion-proof box. Background technique [0002] In the production process of petroleum, coal, textile, chemical and other industrial sectors, flammable and explosive gases or dust are often produced. The surrounding air of such production units is often explosive due to the mixture of flammable and explosive gases or dust. Once it is ignited by an open flame That is, a violent explosion occurs and a major accident is caused. The electric sparks generated during the operation of working electrical equipment in the above environment are one of the important causes of such accidents, because the external explosive gas often penetrates into the interior of the electrical equipment through the gaps in the shell of the electrical equipment; electrical equipment Overheating will occur during operation, and flammable and explosive gases will be released from the ins...

AI Technical Summary

Problems solved by technology

The electric sparks generated during the operation of working electrical equipment in the above environment are one of the important reasons for such accidents, because the external explosive gas often penetrates into the interior of the electrical equipment through the gaps in the shell of the electrical equipment; electrical equipment Overheating will occur during operation, and flammable and explosive gases will be released from the insulating oil or other organic insulating materials in the electrical equipment; in this way, once the electrical equipment generates sparks, the flammable and explosive gases inside the shell may be released. If it is ignited, it will explode, and at the same time, it may detonate the flammable and explosive gas in the outer space and cause a major accident.
