摘　　要：110kV浩-默-祁线于1999年12月投入运行以来,发生多次跳闸事故,严重影响安全运行。文章就浩-默-祁线跳闸原因从现场调查、试验分析等多方面进行了论述,给出了各工况下的电气间隙值、悬垂绝缘子串绝缘长度、悬垂串全长及最小片数,在一定试验数据的基础上,对不同海拔高度线路间隙值及绝缘长度进行修正和外延,提出了浩-默-祁线闪络跳闸的主要原因及解决措施。Since Putting into operation from Dec.of 1999, 110 k V Hao-Mo-Qi transmission line has occ urred trip accident several times, and this influenced the safe operation se riously. The paper expounds the trip reason from spot investigation, test and an alysis etc, provides the electric clearance value, suspending insulator string l ength, suspending string length and minimum number of piece in each condition, a nd makes some modification and extension on the transmission line clearance val ue and insulation length of different elevation based on certain test value, as well as proposes the main reason of trip and provides the solving method.
