[0002] A transformer is an electrical device that uses the principle of electromagnetic induction to convert AC power of one voltage level into AC power of another voltage level of the same frequency through electromagnetic coupling between coils. The transformer oil seal is a component inside the transformer. It is a seal used to prevent transformer oil leakage. The main function of the transformer oil seal is to ensure that the oil inside the transformer will not leak due to mechanical movement or pressure changes. At the same time, it allows the gas inside the transformer to exchange with the outside world to maintain the pressure balance inside the oil tank, and prevent external pollutants from entering the transformer and affecting the normal operation and insulation performance of the transformer.

For example, they are easily affected by the chemicals in the transformer oil and the corrosive substances in the external environment, which causes the oil seals to be corroded and damaged, thereby affecting the service life of the transformer. Therefore, it is necessary to design a corrosion-resistant transformer oil seal. Utility Model Content

[0024] Working principle: When the oil seal is working, the internal anti-corrosion gasket 2 will come into contact with the chemical substances in the transformer oil or the corrosive substances in the external environment. The setting of the anti-corrosion gasket 2 can effectively reduce the corrosion of the oil seal by the two, thereby avoiding damage to the oil seal body 1 and causing the life of the transformer to decrease. At the same time, when the anti-corrosion gasket 2 needs to be replaced or cleaned, it is only necessary to press the pressing block 9 inside the opening grooves 12 on both sides to drive the connecting block 7 to slide along the inclined surface on the inclined surface block 6, thereby pushing the corresponding two L-shaped plug blocks 5 to move toward each other, and causing the spring 10 to press By shrinking, the L-shaped plug 5 can be disengaged from the interior of the slot 4 and the restrictive effect of the L-shaped plug 5 on the anti-corrosion gasket 2 can be released.

When the L-shaped plug 5 is inserted into the slot 4, release the pressing block 9. Under the restoring force of the spring 10, the L-shaped plug 5 will automatically snap into the slot 4, and the installation of the anti-corrosion gasket 2 can be completed. It is simple and convenient.
