Abstract: In view of safety risks such as electric shock and short circuit in the daily maintenance and cleaning process of transformers, this paper develops a distribution transformer electric cleaning equipment, including high-voltage electric cleaning mechanism, control terminal and electric trolley. The device can remotely control the height adjustment of the electric push rod and the angle direction of the spray gun through a small RF remote control and is equipped with an automatic cleaning program. The one-button operation is realized without additional manual intervention, and the environmental temperature and humidity can be monitored to improve cleaning efficiency and safety.
