High-voltage switch cabinet protection shell and switch cabinet thereof

The invention discloses a high-voltage switch cabinet protection shell and a switch cabinet thereof, and belongs to the field of switch cabinet structures. A high-voltage switch cabinet comprises a cabinet body, a front end cover, a drying mechanism, a clamping mechanism and a switching mechanism. The front cover plate is slidably connected to the front end of the cabinet body, and the drying mechanism is arranged at the rear end of the cabinet body, so that the interior of the cabinet body is dried, and the safety accident of electric leakage caused by excessive humidity in the cabinet body is avoided; the operation time of the drying mechanism is controlled by arranging the clamping mechanism, and the situation that the drying mechanism operates in the closed cabinet body, the temperature in the cabinet body rises rapidly, and normal operation of circuits and electric devices in the cabinet body is affected is avoided; the switch mechanism is arranged in the cabinet body to realize linkage between the switc
