摘　　要：由于直流分量的作用，换流变压器阀侧绕组端部电场特性与电力变压器有很大差别。本文首先分析了该电场的励磁电压类别；然后介绍了油纸复合绝缘的材料特性；最后通过算例总结了各种励磁电压作用下，油纸复合绝缘中的电场分布特点。Due to the influence of DC branch, there are considerable differences in the characteristics of electric field at ends of valve-side winding between a converter transformer and a power transformer. The sorts of excitation voltage in the electric field are analyzed firstly in this paper, and then the material features of oil-paper combination insulation are introduced, the distribution characteristics of electric field of oil-paper combination under different excited voltages are summaried finally by an example.
