In order to prevent the transmission lines from falling down and breaking due to ice, the power supply system often uses a vehicle-mounted ice-melting device to de-ice the transmission lines. The main equipment of the vehicle-mounted ice-melting device is the vehicle-mounted transformer. The vehicle-mounted ice-melting transformer has strong mobility, can be put into operation in a short time, is flexible to operate, and is simple and convenient to install.
