摘　　要：将有限元法用于500 kV线路合成绝缘子串上电压分布计算,计算结果用于屏蔽环位置的优化。建立考虑屏蔽环、分裂导线、横担的三维静电场模型,探讨并选取模型合适的外边界长度。计算并对比两个屏蔽环多个位置组合的电压分布,选取最优的位置组合。Finite element method is applied to the calculation of voltage distribution along composite insulator strings of 500 kV transmission lines, and the result is applied to position optimization of grading rings. 3D electrostatic model is established and grading rings, bundle conductors, cross arm are considered. The length of exterior boundary is discussed and suitable length is selected. The voltage distribution of several position combinations of the two grading rings is calculated and compared, and the best position combination is selected.
