基于相场法的变压器油纸绝缘电树枝数值模拟
Numerical simulation of electrical treeing in transformer oil-paper insulation based on the phase field method
摘要
Abstract
The phase-field model can be used to observe the formation process of electrical treeing in oil-paper insulation under high-voltage conditions.A two-dimensional mesoscale phase-field model of oil-paper insulation was established,and the growth of electrical trees under electro-thermal coupled fields was simulated using the multiphysics simulation software COMSOL Multiphysics 5.6.The formation process of electrical trees within oil-paper insulation under three distinct electric field strengths was investigated.The study reveals that at 60 ℃,when considering the influence of electro-thermal coupling on the growth of electrical trees,a cumulative effect of electric field strength distortion exists,which serves as a critical factor contributing to the degradation of oil-paper insulation.关键词
