Abstract

The invention discloses modified transformer oil with excellent insulation strength. The modified transformer oil is prepared from the following raw materials: naphthenic base oil, modified nano-titanium dioxide, 2,6-butylated hydroxytoluene, 2-(2'-hydroxy-5'-methylphenyl) benzotriazole, benzotriazole, n-dodecylbenzene, zinc acetylacetonate, polyimide, ethanediamine, a ultraviolet absorbent UV-P, poly(vinyl butyl ether), dibutyl phthalate, an antioxidant, a silane coupler KH-560, boron carbide, silicon nitride, copper powder, methyl acrylate, polyethylenesulphonate, stearic acid and pentaerythritol. The invention further provides a method for preparing the modified transformer oil with excellent insulation strength. The modified transformer oil prepared by the method has excellent insulation strength.

Description

technical field [0001] The invention relates to a transformer oil, in particular to a modified transformer oil with excellent dielectric strength and a preparation method thereof. Background technique [0002] Mineral oil-based transformer oil has been widely used in various power equipment such as oil-immersed transformers because of its good insulating properties. With the continuous improvement of the voltage level and capacity of transmission lines, the reliability of transmission equipment is increasingly required, and the development of transformer oil with excellent insulation properties has become one of the important tasks to ensure the reliable operation of large power equipment such as transformers. [0003] The dielectric strength of transformer oil in the prior art cannot meet the requirements of actual use, so it is urgent to design a modified transformer oil with excellent dielectric strength to solve the problems in the prior art.
