The invention discloses a movable power distribution cabinet which comprises a cabinet body. The cabinet body is connected with moving wheels. Lifting rods are arranged at the moving wheels on the bottom of the cabinet body and are connected with the cabinet body and outer pedals. The pedals are arranged outside of the cabinet body. Isolation moisture-proof pads are arranged on both sides of the cabinet body. A water-absorbing layer, a heat-insulating layer and a moisture-proof layer are arranged on in the moisture-proof pad. Power distribution equipment is disposed on the upper side inside the cabinet body. The lower part of the cabinet body is equipped with a grounding anti-arc device. The movable power distribution cabinet can be freely moved. Telescopic rollers can not only ensure the free movement of the power distribution cabinet, but also can fix the position of the power distribution cabinet. The dustproof, moisture-proof and heat insulation performance of the movable power distribution cabinet is improved. The multiple attributes of the equipment can extend the working hours within the power distribution cabinet and reduce equipment aging. The equipment is simple in structure and easy to replace and saves energy consumption.
