[0002] The oil-immersed transformer is a new type of high-performance transformer with a more reasonable structure and better performance. Its three-dimensional wound core has three core columns arranged in an equilateral triangle, with no air gap in the magnetic circuit, tighter winding, and the three magnetic circuits are of the same length and the shortest. The cross-sectional area of ​​the core column is closer to a circle, so the performance is further improved, the loss is reduced, the noise is reduced, the three items are balanced, and the third harmonic component is reduced. This product is more suitable for urban and rural, industrial and mining enterprise power grid transformation, and is more suitable for combined transformers and prefabricated substation transformers.

[0003] However, the existing oil-immersed transformer needs to frequently check the internal liquid during use, so the oil tank cover needs to be frequently removed. The existing oil tank cover is generally fixed to the oil-immersed transformer by multiple bolts, which results in the need to remove the bolts one by one, which is not only time-consuming and laborious, but also increases the risk of operators. Therefore, we make improvements on this and propose an oil tank cover for an oil-immersed transformer. Summary of the invention
