Description

technical field [0001] The present disclosure relates to transformer oil, in particular to a method for analyzing the stability of nano-modified transformer oil. Background technique [0002] In order to improve the operating efficiency of the transformer, it is very important to improve the stability of the transformer oil. The insulation performance of the transformer oil directly affects the operating life of the transformer. Nano-modified transformers are obtained by uniformly dispersing a certain quality of nanoparticles in the transformer oil. Oil, its insulation performance, heat dissipation performance and anti-aging, anti-moisture performance have been significantly improved. However, in the traditional experimental environment, some conditions in the real molecular system are not easy to realize and simplify, so it is not conducive to the study of the influence of different factors on the molecular system, and it is difficult to deeply understand the behavior of th...
