摘要

架空输电线路下方山火产生的火焰和烟雾会导致间隙绝缘强度下降，可能造成线路跳闸、停运事故。为研究植被燃烧烟雾对间隙击穿电压的影响，文中搭建了间隙击穿模拟试验平台，开展了不同湿度潮湿杉木燃烧烟雾的交流击穿试验，拟合得到了植被湿度与间隙平均击穿电压梯度的关系式。研究结果表明：潮湿植被燃烧不充分时会产生大量灰白色或黑灰色烟雾，且湿度越大火焰高度越小，最高可下降约40%；燃烧初期冷烟全桥接时间隙的平均击穿电压梯度为163 kV/m，约为空气的60.8%；正常生长态的杉木火焰/烟雾间隙平均击穿电压梯度最低为56.5 kV/m，仅为纯空气间隙的20%左右。研究成果可为山火条件下输电线路跳闸预测预警提供参考。

Abstract

The flames and smoke generated by the wildfires beneath the overhead transmission line can reduce the insulation strength of the air gap

potentially leading to line trip and outage. To investigate the influence of smoke from burning vegetation on the breakdown voltage of the air gap

a simulated gap breakdown platform is set up in this study. AC breakdown tests are carried out using smoke from burning wet China fir at different humidity levels

and a relationship between the vegetation moisture content and the average breakdown voltage gradient of the air gap is obtained through fitting. The study results show that in case of incomplete combustion of the wet vegetation

a large amount of ash-white or dark-grey smoke can begenerated

and the higher the humidity

the smaller the flame height

with a maximum reduction of about 40%. The average breakdown voltage gradient of the air gap bridged by cold smoke at the beginning of burning is 163 kV/m

approximately 60.8% of air. The lowest average breakdown voltage gradient of the gap in the flame/smoke of China fir at normal growth state is 56.5 kV/m

which is only about 20% of that of the air gap. The study results can provide a reference for predicting and warning of line tripping under wildfire conditions.
