摘要

110 kV架空输电线路多采用复合绝缘子进行绝缘支撑，为均匀复合绝缘子表面电场，会在其高压侧或低压侧安装均压环。不同型式、不同安装方式的均压环对复合绝缘子表面电场的影响不同。为获得以降低鸟粪闪络概率为目标的复合绝缘子均压环最优参数组合及安装策略，通过搭建三维仿真模型及真型试验平台，采用仿真和试验方法开展110 kV架空输电线路复合绝缘子均压环多因素选型研究。结果可为110 kV架空输电线路复合绝缘子均压环的安装、运维提供依据。

Abstract

110 kV overhead transmission lines commonly use composite insulators for insulating support.To ensure a uniform electric field distribution on the surface of these composite insulators

voltage equalization rings are installed either on the high-voltage side or on both the high-voltage and low-voltage sides.The effects on the electric field distribution vary based on the types and installation methods of the equalization ring.To obtain the optimal parameters combination and installation strategy of composite insulator voltage equalization rings and to minimize flashover risks due to bird droppings

both a 3D simulation model and a physical testing platform are developed.Through simulation and testing

a multi-factor selection study is conducted for equalizing rings on 110 kV overhead transmission line composite insulator equalizing rings.The research results can provide a basis for the installation

operation and maintenance for 110 kV overhead transmission line composite insulators.
