Description

technical field [0001] The invention relates to the technical field of transformer oil, in particular to an anti-corrosion core-shell structure nano-modified transformer oil containing cottonseed 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 nanoparticl...
