This utility model relates to the field of switchgear technology, specifically to a medium-voltage switchgear with a moisture-proof structure; it includes a switchgear body and a dehumidification mechanism. The dehumidification mechanism includes a mounting base, a fan, a sealing plate, a threaded pipe, a cross ventilation box, a limiting mesh plate, a threaded ventilation cover, and a dust removal device. When the electrical equipment inside the switchgear body is working, the fans located at its air inlet and air outlet will operate accordingly. The fan on the air inlet side draws in cold air from the outside, and the fan on the air outlet side draws in hot air from the inside to the outside. When the air enters, it passes through a desiccant pack placed between the cross ventilation box and the limiting mesh plate to remove moisture, so that the air entering the cabinet body is in a dry state, avoiding the electrical equipment from working in a humid environment for a long time, thereby achieving moisture-proof treatment of the switchgear body and improving the working stability of the internal electrical equipment.
