Explosion-proof analysis shelters are divided into two types: positive-pressure type and flameproof type. There is no difference in scope of use or explosion-proof performance between the two types; both can meet explosion-proof requirements. The difference lies in the structure and explosion-proof form。

The flameproof type explosion-proof analysis shelter adopts a local positive-pressure structure. The principle is to treat each type of electrical equipment inside the explosion-proof shelter as an individual unit, all using explosion-proof electrical equipment. Generally, analyzer cabinets need to be made into positive-pressure explosion-proof cabinets, while other electrical equipment is flameproof。This type of shelter does not allow the use of ordinary cabinets or ordinary electrical equipment inside。
