An oil-immersed power transformer based on negative pressure overflow prevention filling

Abstract

The invention relates to the technical field of transformers, and discloses an oil-immersed power transformer based on negative pressure overflow prevention filling, comprising a transformer body, the outer surface of the transformer body is fixedly connected with cooling fins, and the upper surface of the transformer body is respectively The low-voltage bushing and the high-voltage bushing, the upper end of the transformer body is fixedly connected with an oil pillow, the oil pillow is connected with the inside of the transformer body, the right end of the oil pillow is fixedly connected with a protective shell, and an oil injection hole is opened on the upper surface of the oil pillow. The internal movable clamping of the oil injection hole is blocked, and the front side of the transformer body is fixedly connected with an oil discharge pipe. The oil-immersed power transformer based on negative pressure overflow prevention filling can avoid the vibration generated by the transformer body from causing damage to the internal electronic components, thus avoiding the short circuit phenomenon in the internal circuit of the transformer body, and ensuring the normal voltage regulation and transmission of the transformer body. As well as avoiding the financial expense of repairing and replacing electronic components.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to an oil-immersed power transformer based on negative pressure overflow prevention filling. Background technique [0002] With the continuous development of the State Grid, transformers have become an indispensable equipment in circuit transmission, and transformers with strong performance and easy maintenance are required in the power supply and distribution systems of industrial and mining enterprises and civil buildings. Therefore, oil-immersed power transformers have become a popular User's choice. [0003] The patent with the application number CN201910166367.3 discloses an oil-immersed power transformer based on negative pressure overflow prevention filling. The technical solution proposes that after the voltage transformer is used for a long time, in order to ensure the stability of the transformer, the transformer needs to be oil changed , When changing the oil, it ne...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an oil-immersed power transformer based on negative pressure overflow-proof filling, which has the advantages of shock absorption and buffering for the transformer as a whole, and solves the problems of most existing transformers. The shock absorbing mechanism is usually set under the electronic equipment that generates vibration, and then completes the shock absorption and buffering of the vibration. Although this method can reduce the vibration force, it cannot protect the transformer as a whole.
