1. Induction heating method: The oil - immersed transformer body place in the original tank, the tank outside the winding coil into the current, the use of subcutaneous vortex heating to dry. The tank wall can be padded with asbestos slats, and the wires are wound on the asbestos slats.
2. Hot air drying method: Place the transformer in the drying chamber and allow the hot air to dry. Drying room can be set up based on the size of the device, the wall covered with asbestos board, drying room should be as small as possible, the spacing between the panel and the transformer should not be greater than 200mm, the hot air should not be blown directly to the body, as even as possible blowing to the ministry from the body below, so that moisture through the box vent holes.
3. Oven drying method: If you repair the oven equipment, small-capacity transformer can use this method, drying the body hanging into the oven, control the internal temperature of 95 ℃, the upper part of the oven should have ventilation holes, to release the evaporation of moisture.
In addition, in the drying process should have a special to care, to pay special attention to safety.
