The invention relates to the technical field of explosion-proof electric appliance cabinets, in particular to a pressure-relief explosion-proof electric appliance cabinet which comprises a cabinet body, a pressure relief valve, a positive pressure system and an isolation assembly. The cabinet body comprises an outer shell and an inner shell; the isolation assembly comprises four groups of isolation plates, a pressure relief cavity formed between the isolation plates and the inner shell, and a pressure relief plate connected with the isolation plates; a pressure valve is arranged at the corner angle of the inner shell; a positive pressure cavity is formed between the outer shell and the inner shell, and a mounting cavity is formed in the inner shell; and when high pressure is generated in the mounting cavity, the isolation plate is opened to introduce high-pressure gas into the pressure relief cavity for pressure relief. According to the invention, by arranging the isolation assembly to isolate the electrical components in the inner shell and arranging the pressure relief cavity, secondary disasters caused by internal high-temperature and high-pressure gas leakage can be prevented through the pressure relief cavity when the internal electrical components break down and burn.

The present application belongs to the technical field of gas supply system, especially to the gas container gas supply system and method, the system comprises a plurality of storage cavities, the storage cavity is provided with a clamping mechanism, the mechanism can exert vertical pressure from the bottle shoulder and simultaneously clamp from the side, realize the stable fixation of the gas storage tank, the round groove is provided with a connecting head, the outer wall of the gas storage tank valve handle is provided with a clamping groove, the outer wall of the gas outlet end is provided with a fixing ring with a specific shape insertion hole, the matching mechanism comprises a pin rod which can be inserted into the clamping groove, only when the mounting ring at the bottom of the connecting head and its pressure rod and the insertion hole of the fixing ring are correctly matched and pressed, the pin rod can be driven to rotate and separate from the clamping groove, allowing the valve handle to open, thereby preventing gas connection error, the gas supply system improves the stability of the fixation of the gas storage tank, avoids gas misconnection, and enhances the adaptation ability of the output interface.
