摘要
利用有限元法计算了二维场中的电场强度，并分析了油纸复合绝缘引起的电场畸变。在最不利的情况下，油隙和纸角中的场强最大值Ｅｍａｘ分别为均匀介质场强的２．０倍和１．７倍。研究结果对电力变压器绝缘结构设计和故障分析具有参考价值。
A finite-element method has been used to calculate the electric field strength in 2-dimensional field and to analyze the electric field distortion caused by oil-paper compound insulation structure in this paper. In the worst situation,the maximum of electric field strength(Emax) in oil gap and paper corner is 2.0 and 1.7 times respectively as much as those in even medium field,and the conclusion given in this paper can be used for reference in design for transformer insulation and inanalysis of insulation faults in power transformer.
