Problems solved by technology

[0003] At present, the insulating oil in domestic oil-immersed transformers is mostly a single mineral oil component. Mineral oil is directly refined and made. Because it contains more double bonds inside, it has a weak ability to absorb and wrap moisture inside the transformer. The insulation effect of the transformer is poor, and the aging phenomenon is obvious, which affects the overall life of the oil-immersed transformer

Embodiment 1

[0010] The insulating oil is composed of 3 parts of olive oil, 7 parts of mineral oil, 1 part of tea polyphenol and 8 parts of rapeseed oil in proportions by weight.

[0011] In the present invention, the traditional single mineral oil is used as the insulating oil, and rapeseed oil and olive oil are added as the natural ester component of the transformer insulating oil, because the absorption rate of rapeseed oil and olive oil to water is higher than that of mineral oil , so when moisture enters the inside of the transformer, rapeseed oil and olive oil can act on water molecules and wrap them at the same time, so as to improve the ability of the insulating oil to absorb moisture; in addition, tea polyphenols are added to this formula , to improve the stability of the transformer insulating oil and oil tank, and improve the overall life of the transformer.

Abstract

The invention discloses a transformer insulating oil. The transformer insulating oil is prepared from, by weight, 3 parts of olive oil, 7 parts of mineral oil, 1 part of tea polyphenol and 8 parts of colza oil. According to the transformer insulating oil, traditional single mineral oil serves as the insulating oil, and the colza oil and the olive oil are added into the single mineral oil to serve as natural ester components of the transformer insulating oil; because the water absorption rate of the colza oil and the water absorption rate of the olive oil are relatively high compared with that of the mineral oil, under the condition that moisture enters a transformer, the colza oil and the olive oil can synchronously react with and wrap water molecules to improve the trace-moisture absorbing and treating capabilities of the insulating oil; besides, tea polyphenol is added into the formula to improve the stability of the transformer insulating oil and the stability of an oil tank, so that the overall service life of the transformer is prolonged.

Description

technical field [0001] The invention relates to a transformer insulating oil. Background technique [0002] At present, the transformers in most power transmission systems are filled with insulating oil, which plays the role of electrical insulation and heat conduction at the same time. Transformers are required to work reliably and efficiently for many years, and the quality of the transformer oil plays an important role. Transformer oil and oil-impregnated paper insulation together constitute the main components of the transformer's internal insulation. During long-term operation, both of them will age under the influence of electricity, heat and other factors, which will cause the insulation performance of the transformer to decline. Moreover, the aging process of oil-paper insulation is irreversible, and its performance directly determines the service life of the transformer. [0003] At present, the insulating oil in domestic oil-immersed transformers is mostly a sing...
