[0002] Mineral insulating oil has good thermal conductivity and electrical insulation properties. As a cooling medium and insulating medium, it has been widely used in all aspects of the power industry for decades. However, with the continuous development of modern industry and the continuous application of related compact equipment , the size of electrical equipment continues to shrink, and the traditional mineral insulating oil is becoming more and more difficult to meet the current and future development requirements of the power industry, and the need to improve its thermal conductivity and electrical insulation performance is becoming more and more urgent

[0003] At present, many scholars at home and abroad have shown that the electrical insulation performance and thermal conductivity of insulating oil can be effectively improved by adding nano-particles of specific types and specific proportions. However, this new nano-modified insulating liquid is still in the laboratory preparation stage and has not yet Industrialized production conditions, one of the important hindering factors is that the preparation process requires multiple people to participate repeatedly, and there is no quantitative standardized preparation process

At the same time, the preparation process involving many people also has the risk of unpredictable contamination of the liquid, which affects the quality of its products
