Encapsulation type electrical equipment explosion-proof principle - Solutions - Huaqiang Electronic Network

Photocoupler

The explosion-proof principle of encapsulated electrical equipment is: the electrical equipment is likely to produce an arc, spark or high temperature part of the ignition mixture to be encapsulated in the potting agent, to avoid contact of these electrical parts with the explosive mixture, so that the electrical equipment is normal In the event of an overload or failure in operation or approval, the surrounding explosive mixture cannot be ignited. The encapsulated electrical equipment is encapsulated by the entire equipment, and the components are also sealed. The encapsulated part that is subjected to the encapsulation and explosion-proof measures cannot be used in an explosive environment alone, and must be combined with the explosion-proof electrical equipment using the part before it can be used in an explosive environment. Commonly used encapsulated electrical equipment or encapsulated components mainly include batteries, batteries, fuses, voltage transformers, motor and transformer windings, cable joints, and the like. The mark of the encapsulated electrical equipment is "m".
