In the daily use of baoding oil-immersed transformer, it is inevitable to encounter problems of one kind or another, among which oil leakage phenomenon is very common. Once oil leakage of baoding oil-immersed transformer will directly affect the normal operation of transformer. Therefore, in this case, it is of vital importance to find out the cause of oil leakage of transformer timely and solve it. Next, we will look at the baoding oil immersed transformer factory to the transformer oil leakage reason several analysis.
Main reasons for oil leakage of baoding oil immersed transformer are as follows:
1. Rubber seal failure and weld cracking.
Because there are many welding points of transformer, there are many leakage ways in the welding plant in daily use. The direct leakage may be caused by rubber sealing failure, weld cracks, pores, slag inclusion and so on.
2. Poor quality of transformer manufacturing.
In the manufacturing process of transformers, many welding spots in oil tanks, welding plants, welding difficulties, welding materials, welding specifications, techniques and technologies will affect the welding quality, resulting in the leakage of oil in transformers due to pores, sand holes, virtual welding and unsoldering.
3. Aging of sealing parts, crack deformation.
The leakage of baoding oil-immersed transformer often occurs at the connection, and more than 95% is mainly caused by sealing parts. The quality of sealing parts mainly depends on its oil resistance performance. If the oil resistance performance is poor, the aging speed will be faster, especially under high temperature, and the aging speed will be faster, which will easily cause sealing parts to age, crack, deteriorate, deform and even fail, resulting in transformer leakage of oil.
4. Improper installation.
If the transformer flange connection is uneven, the stress around the sealing gasket during installation is not uniform, and the bolts around the sealing gasket are artificially non-uniform under the stress, the flange joint is malformed and malformed, which will make one side of the sealing gasket under high stress, one side under low stress, and the other side under low stress is easy to cause leakage due to insufficient compression.
