The explosion-proof principle of flameproof electrical equipment is to place the live parts of the electrical equipment in a special casing that has the function of isolating the sparks and arcs generated by the electrical components in the casing from the explosive mixture outside the casing and can withstand the entry. The explosive mixture inside the shell is exploded by the sparks and arcs of the electrical equipment in the shell, and the outer casing is not destroyed. At the same time, it can prevent the explosive products in the shell from being blasted to the explosive mixture outside the shell, and will not cause explosiveness outside the shell. The mixture burns and explodes. This special casing is called the "explosion-proof casing". An electrical device having a flameproof enclosure is referred to as an "explosion-proof electrical device." Explosion-proof electrical equipment has good flameproof and explosion-proof performance, and is widely used in explosive environment workplaces such as underground coal mines. The mark of the explosion-proof electrical equipment is “dâ€.
In addition to the electrical part, the main structure of the explosion-proof electrical equipment includes the flameproof enclosure and some components attached to the casing, such as gaskets, transparent parts, cable (wire) introduction devices and junction boxes. According to the explosion-proof principle of flameproof electrical equipment, we know that the flameproof enclosure should have explosion-proof and flameproof performance. The so-called explosion resistance is the ability of the outer casing to withstand the explosion pressure generated by the explosion of the explosive mixture in the shell without causing damage and dangerous deformation. The so-called explosion-proof performance is the flame that is ejected when an explosive mixture in the outer casing explodes, and does not cause the explosion of the flammable mixture outside the shell. In order to achieve the explosion-proof and flameproof performance of the flameproof enclosure, there are special requirements for the shape, material, volume and structure of the flameproof enclosure.Components of automobile parts
