Antioxidant nano modified transformer oil and preparation method thereof

Abstract

The invention discloses antioxidant nano modified transformer oil. The antioxidant nano modified transformer oil is prepared from, by weight, 100-150 parts of naphthenic base oil, 5-10 parts of castor oil, 0.1-0.15 part of nanosilicon dioxide hollow spheres, 0.3-0.5 part of 2,6-butylated hydroxytoluene, 0.1-0.15 part of benzotriazole, 0.3-0.5 part of propylgallate, 0.01-0.015 part of quercetin,0.01-0.015 part of tetraethoxysilane, 0.1-0.15 part of sodium cetostearyl sulphate and 0.01-0.015 part of vinyltriethoxysilane. The transformer oil has excellent insulation and heat dissipation performance, is stable in property and long in service life, further has the advantage of good antioxidant performance, and is high in practicality.

Description

technical field

[0001] The invention relates to the technical field of transformer oil, in particular to an anti-oxidation nano-modified transformer oil and a preparation method thereof. Background technique

[0002] With the continuous development of power transformers in the direction of high insulation, large capacity and miniaturization, more and more attention has been paid to improving the performance of insulating media. Transformer oil is a low-viscosity oil with two functions of insulation and heat dissipation. It is an important part of the current transformer insulation system. Its performance plays an important role in the safety and reliability of the long-term operation of the transformer. Therefore, how to improve the performance of transformer oil has become one of the research hotspots. Nano-modified transformer oil is a new type of transformer oil obtained by modifying transformer oil with nanoparticles. It has high heat dissipation and unique electrical p...
