摘　　要：本文中笔者利用有限元软件使用切向法对场域内纸板、角环等绝缘件之间油隙电力线进行绘制,并可沿每条电力线计算所经路径的平均场强值,考虑电场不均匀度引入不均匀系数求取每条电力线绝缘裕度,并通过实例验证了此方法的可行性。The objective of this paper is to analyze electrical stress between angel ring,press board&other insulation parts of transformers using finite element software by tangential method,the power line is drawn in the electric field under consideration average field strength value is calculated along each power line.As the electric field considering the electric field is non-uniformity in nature,the non-uniformity coefficient is introduced to calculate the insulation margin along each power line,and an example is given to verify the feasibility of this method.

关 键 词：变压器 切向法 电力线 平均场强值
