| 摘 要： | 为合理利用设计复合绝缘子和玻璃绝缘子,建立了分析500 kV线路悬式绝缘子电位分布的计算模型,并利用ANSYS计算和分析比较两者的电位分布。结果表明,加均压环可显著改善绝缘子的电位分布,玻璃绝缘子串加均压环后的轴向电位分布要优于复合绝缘子,且均压环的半径对绝缘子两端关键部位的电压分布有影响。

| Abstract: | In this paper,Finite Element Method(FEM) and FEM software-ANSYS are introduced,simulation modeling is outlined,ANSYS is used to calculate the electric potential distribution of composite insulator and glass insulator under different condition.The aim of the computation is to analyze and compare these two kinds of insulator from view of electric characteristic.The suspension insulators used in 500 kV transmission lines are studied.The result can be served as a reference in future design and proper use of line insulator.According to the simulation and analysis,it can be obtained that the electric potential distribution has been improved greatly with grading ring and the improvement of glass insulator strings is more obvious than that of composite insulator,also,the electric potential distribution is influenced by the size of grading rang near the high voltage side and grounding side. |
