Flameproof type, a type of explosion-proof electrical equipment structure. Flameproof type explosion-proof type refers to the sealing of all components of the equipment that may ignite explosive gas mixtures in a single enclosure. The enclosure can withstand the combustible mixture that penetrates into the interior of the enclosure through any joint surface or structural gap of the enclosure without damage, and will not cause external explosion The ignition of explosive environments formed by various gases or vapors (see GB 3836 2 standard). Place all components that may generate sparks, arcs, and hazardous temperatures into an explosion-proof enclosure, which separates the internal space of the equipment from the surrounding environment. There are gaps in the explosion-proof enclosure, which may contain explosive gas mixtures due to the breathing and gas permeation effects of electrical equipment. When an explosion occurs, the enclosure can withstand the generated explosion pressure without damage. At the same time, the structural gaps of the enclosure can cool the flame, reduce the flame propagation speed, or terminate the acceleration chain, preventing flames or dangerous flame products from crossing the explosion-proof gap and igniting the external explosive environment, Thus achieving the purpose of explosion-proof. Explosion proof type "d" is classified into Class I and IIA, IIB, and IIC according to the types of explosive gas environments it is allowed to use. This explosion-proof type of equipment is suitable for areas 1 and 2
