The cooling methods are divided into natural air cooling and forced air cooling. In the case of natural air cooling, the transformer can operate continuously for a long time at the rated capacity.

[0003] Chinese Patent CN220357914U discloses a dry-type transformer cabinet with a drying function. In this technical solution, a motor is arranged to drive the fan blades to rotate, so that the fan blades drive the air inside the cabinet to flow, thereby dissipating heat from the inside of the cabinet. At the same time, the outside air enters the inside of the cabinet through the ventilation filter plate, and the drying plate inside the installation box dries the outside air, and then discharges it through the ventilation holes, preventing moist air from entering the inside of the cabinet and avoiding affecting the dry-type transformer.

[0004] However, this dry-type transformer cabinet with a drying function does not have a humidity detection function. When the humidity of the drying plate is high, it is impossible to promptly warn the staff to replace it, which is not conducive to the dry use of the inner cavity of the dry-type transformer cabinet.
