Oil leakage in transformers not only leads to a decrease in oil volume but may also trigger fire hazards and other safety issues. Therefore, timely handling is required. Here are several common methods of treatment:

现场 replacement of sealing parts: This is a common method for dealing with transformer oil leakage. When replacing the sealing parts, it is necessary to first drain some of the oil from the transformer to facilitate the replacement process. During the replacement, ensure the sealing surface is clean and free of oil stains and debris, and select appropriate sealing parts for replacement.

2. Welding Repairs: For oil leakage issues caused by welding quality, the method of welding repair can be employed. Before welding, it is necessary to drain all the oil from the transformer and ensure the welding area is dry and clean. During the welding process, attention should be paid to controlling the welding time and temperature to prevent excessive heating within the transformer and potential damage.

3. Utilize High-Polymer Composite Materials: For difficult-to-treat oil leakage areas such as flanges, oil injection pipe valves, etc., high-polymer composite materials can be used for on-site treatment. This method requires no shutdown, pressure release, or oil draining, is easy to operate, and yields significant results.
