摘要

针对330kV架空输电线路复合绝缘子高压端因安装屏蔽环或均压屏蔽环，增加了鸟粪短接高低压端间绝缘距离的问题，搭建仿真模型分析高压端无均压环或屏蔽环、高压端有均压环和圆形屏蔽环、高压端仅有三角形屏蔽环三种工况下复合绝缘子表面电场分布及场强变化情况，进而分析拆除高压端均压环或屏蔽环的可行性。结果表明，在高压端仅安装三角形屏蔽环或不安装屏蔽环时，复合绝缘子高低压端最大场强分别为26.72 kV/cm、27.92 kV/cm。结合上述结果，给出了宁夏不同地区330 kV架空输电线路屏蔽环安装运维建议。

Abstract

This study addresses the issue of increased insulation distance between the high and low ends of composite insulators in 330 kV overhead transmission lines due to the installation of shielding rings or grading shielding rings.A simulation model is built to analyze the surface electric field distribution and field strength variations under three conditions：no grading ring or shielding ring at the high voltage end

a grading ring and a circular shielding ring at the high voltage end

and only a triangular shielding ring at the high voltage end.The feasibility of removing the grading ring or shielding ring at the high-voltage end is also analyzed.The results show that the maximum field strengths at the high and low ends of the composite insulators are 26.72 kV/cm and 27.92 kV/cm

respectively.Based on these findings

recommendation s for the installation

operation

and maintenance of shielding rings on 330 kV overhead transmission lines in different regions of Ningxia are proposed.
