[0002] A control cabinet is a device that assembles switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to electrical wiring requirements. It is commonly used in various power generation, distribution and substations. Electrical components such as control switches and various parts will be installed inside the control cabinet. In this way, a large amount of heat will be generated by the electrical components during operation. The heat accumulated in the cabinet will easily cause the temperature inside the cabinet to gradually increase, and electrical components are prone to explosion when operating in a high temperature environment. Although the heat dissipation ports on both sides of the common control cabinet can dissipate heat, the heat dissipation effect is not significant, and the effect is even worse in hot summer weather. The probability of accidental combustion and explosion of the control cabinet increases. For this reason, the present application proposes an explosion-proof electrical control cabinet.
