[0001] The utility model relates to the technical field of explosion-proof electrical cabinets, in particular to an explosion-proof electrical cabinet for a dust workshop. Background Art

[0002] The electrical cabinet is made of steel and is used to protect the normal operation of components. It can integrate and manage each electrical component in the electrical cabinet, increase the safety protection of electrical products, facilitate operation, and improve electrical performance. Through the reasonable use of electrical cabinets, the service life and technical performance of electrical components can be improved. With the continuous advancement of science and technology, the application scope of electrical cabinets has become more and more extensive. Therefore, explosion-proof electrical cabinets with stronger protection levels have come into being.

[0003] Explosion-proof electrical cabinets can be used in many fields, but the requirements for different fields are also different.

The dust inside the workshop is easily adsorbed on the surface for a long time, affecting its operational flexibility. Moreover, the dust in the workshop can easily enter the cabinet through the wiring pipe, affecting the service life of the cabinet.

[0004] Therefore, it is necessary to provide an explosion-proof electrical cabinet for a dust workshop to solve the above technical problems. Utility Model Content
