Description

Technical Field

[0001] The utility model relates to the technical field of electric control boxes, in particular to a novel explosion-proof electric control box. Background Art

[0002] According to the patent authorization announcement number: CN216959073U, a new explosion-proof electrical control box is proposed. The utility model discloses a new explosion-proof electrical control box, including a cabinet, a hinged cabinet door is arranged on the cabinet, a wind cooling device is arranged on one side of the cabinet, and a gas drop box is arranged on the other side of the cabinet. A sealing device, a gas concentration sensor, a temperature sensor and a fixing plate are arranged in the cabinet. The wind cooling device includes an air inlet and an air outlet. The sealing device is arranged near the air inlet and the air outlet. Electrical components are arranged on the fixing plate. The cabinet is connected to the gas drop box through an air intake valve. The explosion-proof device of the utility model has a built-in temperature sensor and a gas concentration sensor. When an open flame appears in the cabinet, the fuse burns out, and the compressed spring presses against the first slider and the second slider to move in opposite directions.
