Anti-corrosion and wear-resisting nano modified transformer oil with core-shell structure and preparation method thereof

Abstract

The invention discloses anti-corrosion and wear-resisting nano modified transformer oil with a core-shell structure. The anti-corrosion and wear-resisting nano modified transformer oil is prepared from the following raw materials in parts by weight: 100-150 parts of naphthenic base oil, 10-15 parts of rapeseed oil, 0.1-0.15 part of nano titanium dioxide, 0.3-0.5 part of 2,6-di-tert.-butyl-p-cresol, 0.1-0.15 part of benzotriazole, 0.01-0.015 part of ethyl orthosilicate, 0.3-0.5 part of polyethylene glycol phosphate, 0.01-0.015 part of triethoxyvinylsilane, 0.1-0.15 part of isooctyl acidic octadecylamine phosphate and 0.05-0.1 part of disodium ethylene diamine tetraacetate. The transformer oil provided by the invention has excellent insulating and heat dissipation performances and also has stable properties and long service life, and also has characteristics of good anti-corrosion and wear-resisting performances; the transformer oil has a certain protection effect on a transformer system and has high practicability.

Description

technical field [0001] The invention relates to the technical field of transformer oil, in particular to an anti-corrosion and anti-wear core-shell structure 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. [0003] Nano-modified transformer oil is a new type of transformer oil obtained by modifying transformer oil with nanoparticles. It has h...
