Before dealing with oil seepage, it is necessary to carefully analyze and find out the cause of the leakage and the exact leakage point. For the existing oil stains, first clean them with a small flat shovel and wire brush, then clean them with xylene, rinse them with clean water, * * * clean them repeatedly with clean cloth to find the exact location of the leakage points.

Transformer leakage can be roughly divided into sealing leakage and welding leakage. To deal with seal leakage, the main purpose is to improve the sealing quality. For example, if the fastening screws are invalid for casing, oil mark, radiator valve, large cover, on-load switch and other places containing seals, the sealing ring can be replaced or re-glued and sealed. To deal with welding leakage, repair welding can be adopted. In the process of dealing with any kind of oil leakage, the thick material method or lashing method should be prohibited.
