摘要

雷击是引起输电线路跳闸的主要原因，加强绝缘子的绝缘性能有助于提升架空输电线路抵御雷电灾害的能力。文中主要关注均压环加装硅橡胶套能否改善输电线路耐雷性能这一问题。为此，文中首先开展了雷电冲击电压下绝缘子闪络放电实验，获得了新型绝缘子和传统绝缘子的伏秒特性曲线，结果表明硅橡胶套可以让伏秒特性曲线上移。进一步分析放电发展过程的高速影像发现，上述改善主要是因为硅橡胶套抑制了流注放电的起始和增大了先导放电的路径。基于实验结果拟合的伏秒特性曲线，文中仿真计算了均压环的硅橡胶套对输电线路反击耐雷水平和反击跳闸率的影响，结果表明新型绝缘子可以有效地降低输电线路的反击跳闸率，降幅介于9.1%～58.9%之间。上述研究成果有可能为输电线路的防雷改造提供一些新思路。

Abstract

Lightning strikes are a major cause of transmission line tripping

and strengthening the insulating properties of insulators can help to improve the ability of overhead transmission lines to withstand lightning hazards. In this paper whether the installation of silicone rubber sleeve to the grading ring can improve the lightning wistand performance of transmission lines is focucsed. To this end

the flashover discharge experiment of insulators under the lightning impusle is performed firstly in this paper

the volt-secondcharacteristic curves of the new designed and traditional insulators are obtained. The results show that the silicone rubber sleeve can shift the volt-second charcateristic curves upwards. It is found by the analysis of the high-speed images of the discharge process that the improvement is mainly that the silicone rubber sleevehas suppressed the initiation of the streamer discharge and increased the path of the leader discharge. Based on the volt-second characteristic curves fitted by the experimental results

the influence of silicon rubber sleeve of the grading ring on the lightnign withstand level and back-flash-overoer tripping rate of a typical transmission line.The result shows that the new insulator can effectively reduce the back-flashover tripping rate of transmission lines by 9.1% to 58.9%. The above research results may provide some new ideas for the lightning protection renovation of transmission lines.
