结合中国南方电网有限责任公司超高压输电公司所辖500 kV 及以上电压等级交直流线路在2009-2014年的山火跳闸数据，从山火发生时间、故障现场的地形地貌特征及重合闸情况等多个角度对山火引发线路跳闸的特性进行了分析。与直流线路及交流常规型线路相比，山火引发交流紧凑型线路跳闸具有跳闸率高、相间故障比例大、重合闸成功率低等特点。从杆塔结构及导线布置形式等方面对山火引发交流紧凑型线路相间短路的原因进行了分析，导线呈倒等边三角形布置且相间距离较短是山火导致线路相间短路多发的主要原因。

Combining forest fire tripping data in 2009 to 2014 of 500 kV and above voltage grad AC and DC transmission lines ruled by the EHV power transmission company,this paper analyzes characteristics of lines tripping caused by forest fires in aspects of occurrence time,terrain features of failure site and automatic reclosing cases. Compared with DC transmission lines and AC conventional transmission lines,AC compact transmission lines tripping was provided with features of high trip-ping rate,large proportion of interphase failure,low success rate of automatic reclosing,and so on. In aspects of tower structure and conductor configuration mode,reasons for interphase short-circuit of AC compact transmission lines caused by forest fires were analyzed. It was considered that the main reason for frequent interphase short-circuit was inverted equilat-eral triangle configuration of the conductor and short interphase distance.
