Explosion-proof electrical equipment is different from general industrial and civil electrical equipment. It adopts corresponding technical measures in structure and performance and will not cause ignition and explosion in the surrounding explosive gas or dust environment. Choosing suitable explosion-proof electrical equipment is an important means to ensure the safe production of enterprises and reduce explosion accidents. The main problems in practical application are: using ordinary electrical equipment in explosive dangerous places; The whole equipment is not certified; Using fake and inferior products; The installation of explosion-proof equipment is not standardized; Maintenance is not in place and so on. These hidden dangers are very hidden, difficult to be identified by managers and operators, and easy to be ignored. In addition, many industrial and mining enterprises have not systematically established explosion-proof equipment files, and explosion-proof electrical equipment has been in a state of lack of management for a long time. These reasons have also laid hidden dangers for accidents. Therefore, it is necessary to introduce the concept of life-cycle management in the use cycle of explosion-proof electrical equipment and implement hidden dangers control from the source.
