[0002] With the development of society, the trend of automation equipment to replace manual tasks is becoming more and more obvious, and the precision of automation equipment is also increasing, and the requirements for de-manualization in various high-risk jobs are also gradually increasing; the air on the upper part of the general oil conservator It is connected to the outside by a ventilation pipe. In order to prevent the moisture in the air from entering the oil conservator through the ventilation pipe and reducing the insulation performance of the insulating oil, a desiccant is generally placed in the ventilation pipe to dehumidify. However, as the desiccant absorbs more moisture, Its dehumidification effect is also declining, and even after absorbing water, it will release water into the oil conservator to affect the performance of insulating oil. Usually, the above problems can be solved by replacing the desiccant, but due to the dryness in the ventilation duct of the oil conservator Therefore, the present invention proposes an automatic dehumidification device for oil pillow desiccant for transformers, which can greatly reduce the manual participation in the daily maintenance of transformers, and achieve the effect of replacing the process of manual replacement of desiccant. At the same time, the deterioration rate of insulating oil is greatly reduced
