Description

Technical Field

[0001] The utility model relates to the field of explosion-proof control cabinets, and more specifically, to an explosion-proof control cabinet for mining. Background Art

[0002] In order to meet the needs of explosion-proof use inside mine tunnels, the cabinet door or cabinet body of the explosion-proof control cabinet is usually made of metal material and cast in one piece, with strong integrity and sealing. The cabinet door and cabinet body are fixed with multiple bolts at the connection to maintain the sealing of the cabinet door and cabinet body, and prevent flammable gas from entering the cabinet body and being ignited by electric sparks. Therefore, although the existing explosion-proof control cabinet has excellent performance in terms of sealing, due to the tight sealing, the heat generated by the various control electrical appliances installed inside the cabinet body is not easy to dissipate when working, which is easy to affect the stability and service life of each control electrical appliance when working over time. Therefore, we propose a mining explosion-proof control cabinet to solve the above problems. Utility Model Content
