摘要
考虑湖南地理环境、气候条件以及民情民风等因素,分析山火引起的湖南电网输电线路故障跳闸事故;线路故障主要由导线对树木放电造成,受暂态过电压和空气高温游离等因素影响,重合闸成功率低;并提出了防治山火跳闸事故的措施.
With the Hunan＇s geographical surroundings,the climate conditions and the Hunan demos conventions considered,the transmission line trip accidents caused by mountain fire are analyzed in this paper.The trip reason is that the transmission line discharges to the trees under it.And the reclosing failure reasons caused by forest fire are faults transient over-voltage and air dissociation with high temperature.The measures preventing mountain fire are also presented.
