Abstract

The invention discloses nano-modified transformer oil having a core-shell structure and insect repelling and bacterium killing effects. The nano-modified transformer oil is prepared from the following raw materials in parts by weight: 100-150 parts of naphthenic base oil, 1-2 parts of Chinaberry seed oil, 10-15 parts of rapeseed oil, 0.1-0.15 parts of nano-titanium dioxide, 0.3-0.5 parts of 2,6-di-tert-butyl p-cresol, 0.5-1 part of terpilenol, 0.1-0.15 parts of benzotriazole, 0.1-0.15 parts of glycerol monolaurate, 0.01-0.015 parts of tetraethoxysilane, 0.01-0.015 parts of vinyltriethoxysilane and 0.1-0.15 parts of coco-glucoside. The transformer oil has excellent insulation and cooling properties, is stable in nature and long in service life, has insect repelling and bacterium killing effects and is good in hygiene and high in practicality.

Description

technical field [0001] The invention relates to the technical field of transformer oil, in particular to a nano-modified transformer oil with a core-shell structure and a preparation method thereof, which has the effect of repelling insects and sterilizing bacteria. 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. [0003] Nano-modified transformer oil is a new type of transformer oil obtained by modifying...
