Description

Technical Field

[0001] The present application relates to the technical field of transformers, and more specifically, to a fully sealed processing device for transformer oil. Background Art

[0002] As a device that uses the principle of electromagnetic induction to change AC voltage, in order to ensure the normal operation of the transformer, it is often necessary to inject transformer oil into the transformer to provide protection and ensure its normal operation.

The sealing frame wraps the side edges of the tank cover and the fastening plate, and the tank cover is pressed by a pressing structure to reduce the looseness of the tank cover at the fastening plate, thereby improving the sealing performance and realizing the sealing processing of the oil in the oil tank body.

[0004] However, since the oil pipe is only sealed and protected by a sealing plug, the protection means is relatively simple. In actual use, if the transformer is in a highly corrosive outdoor environment, the sealing plug is prone to cracking, resulting in the transformer oil in the transformer being unable to be used in a sealed state due to cracking of the sealing plug.
