The invention provides an automatic dehumidification power transformation box, which comprises a top plate, a dehumidification cylinder, a control cylinder and a box body. The top plate is welded to the top of the box body. The dehumidification cylinder and the control cylinder are welded to the right side of the box body in an embedded mode. The dehumidification cylinder is located right over thecontrol cylinder. Two cabinet doors are hinged to the front surface of the box body through hinges.

Therefore, the aqueous vapor in the metal water collecting barrels can be quickly liquefied on the inner wall of the metal water collecting barrels to form water drops. After the water drops are accumulated to a certain extent, the water drops flow down along the inner wall of the metal water collecting barrel and flow towards water running plates. When water on the water running plates comes up together, the two water running plates can form a current loop. In this way, a power supply for a motor and an electric heating pipe is switched on by an electric wire. The electric heating pipe starts heating to dry the air. The motor drives fan bladesto rotate to form the airflow and the airflow is driven to blow into the box body. The air humidity in the box body is reduced, and the automatic dehumidification is achieved.
