Description

Technical Field

[0001] The utility model relates to the technical field of transformer oil filtration, in particular to a transformer oil filtration and filling device. Background Art

[0002] Transformer oil plays a crucial role in power transformers. It is not only an insulating medium but also undertakes the functions of heat dissipation and arc extinction. Therefore, the quality of transformer oil directly affects the operation safety and stability of transformers. According to the transformer standards, transformer oil needs to meet a series of strict quality requirements, including key indicators such as breakdown voltage, micro water content, and dielectric loss factor. These indicators are greatly affected by the external environment and transportation conditions. Therefore, transformer oil usually needs to have performance indicators far higher than the standard specified values when leaving the factory to ensure that the requirements can still be met during transportation and storage. The methods for filtering transformer oil mainly rely on two ways: physical filtration and chemical treatment. Physical filtration mainly removes mechanical impurities and particles in the oil through filter media such as filter elements; chemical treatment removes moisture, gas, and acidic substances in the oil by adding chemical reagents.

[0003] However, during the storage, operation, and installation of transformer oil, it will be affected by moisture, increasing the water content of the insulating oil, aging, increasing the impurities in the insulating oil, incomplete detection of the oil quality, inaccurate control during the filling process, and lack of automation and intelligent control, which seriously affect its reliability and service life.
