Safe and explosion-proof low-voltage switch cabinet

The utility model relates to the technical field of switch cabinets, in particular to a safe and explosion-proof low-voltage switch cabinet, which is characterized in that air channels are uniformly formed in a base, a box body is mounted on the upper surface of the base, a control panel is mounted at a position, close to the upper end, of the front surface of the box body, and an equipment box is mounted on the upper surface of the box body; and a first motor is mounted in the equipment box. The device is simple in structure, air pressure in the sealing box is detected through the pressure sensor, detection data are transmitted to the control panel, the first motor is made to work through the control panel, so that the threaded rod rotates, the movable plate drives the sealing box to move up and down through threaded connection, and therefore the pressure relief pipe and the connecting pipe are combined in an inserted mode; and a second motor drives a fan to work, so that extraction of gas in the sealing box
