Description

technical field [0001] The invention relates to a transformer oil, in particular to a high ignition point transformer oil 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 ignition point of the transformer oil in the prior art cannot meet the requirements of actual use, so it is urgent to design a transformer oil with a high ignition point to solve the problems in the prior art. Contents of the invention [0004] In order to solve the technical ...
