摘　　要：本文运用组合法──有限元法与模拟电荷法组合分析了电力变压器端部的电场，得出了影响电力变压器端部最大电场强度Ｅ＿（ｍａｘ）与其结构尺寸Ｍ、Ｈ、ρ、ｓ之间的关系，为其绝缘结构设计提供了理论依据，也为电力变压器端部电场的数值计算提供了一种新的方法。The combination method. which the finite element method is combined with the charge simulation method, is applied to analysis the electric fields, insulation construction of winding ends of power transformers. and gains some curves between the maximum electric fields strength of winding ends and constructional size M. H. p and s, and provides theory basis for designing insulation construction. meanwhile gives a new method for numeircal calculation of winding ends electric fields of power transformers.
