What are the causes of oil leakage in oil-immersed transformers? Join Jiangsu Jiali's editor to find out.
Several reasons contribute to transformer oil leakage:
One: Aging and cracking of oil-impregnated transformer sealing gasket
Transformers often leak at the sealed gasket area, primarily due to the aging and cracking of the sealing pad. The quality of the sealing gasket is crucial, as its wear resistance determines its aging rate. Weak wear resistance leads to rapid aging, and high temperatures can easily cause the sealing pad to age and crack, rendering it ineffective, ultimately resulting in transformer oil leakage.
Section two: Oil-immersed transformer welding area has sand holes
The reasons for the formation of the sand hole are primarily due to two key aspects:
Due to poor welding quality, sand holes have formed at the welding areas.
Due to severe rust on the welding areas, oil leakage from sand holes has occurred.
How can an oil-immersed transformer experience oil leakage?
1. Oil-immersed transformer applications experiencing oil leakage due to natural environmental causes
As winter approaches, the sudden change in temperature causes expansion and contraction, leading to loose seals in relevant parts and oil leakage.
2. Inadequate installation method for oil-immersed transformers
