In order to achieve the purpose of the above invention, the utility model includes a cabinet body and a cabinet door. Electrical components are installed inside the cabinet body, and a cabinet door lock is installed on the cabinet door. It is characterized in that: the side square hole of the cabinet body is equipped with an electric cabinet Air conditioner, electric cabinet The air conditioner is connected to the electrical components inside the cabinet through internal cables; the bottom of the cabinet is provided with a waterproof cable fixing head, and the cable passes through the waterproof cable fixing head to connect with the electrical components; the cabinet door is surrounded by cabinets. The door is bent.

An L-shaped rib is welded on the inside of the cabinet door, and the root of the hollow rubber strip is inserted into the L-shaped rib to fix it. When the cabinet door is closed, the head of the hollow rubber strip presses against the front of the cabinet to seal it.

Water guiding grooves are arranged around the opening of the cabinet door.

Described cabinet door lock is made up of upper and lower lock head, lock pull bar and dead bolt.

Compared with the prior art, the utility model is tightly closed as a whole, which can effectively prevent water, moisture, dust, etc. from entering the control cabinet, and avoid damaging the electrical components in the cabinet. The equipped electric cabinet air conditioner maintains the independent circulation of air in the control cabinet, automatically adjusts the temperature and humidity in the cabinet, and ensures the normal operation of electrical components.
