摘　　要：以珠江三角洲某供电所2010年10 kV配电线路跳闸故障数据为样本,统计分析造成线路跳闸的主要原因。得出造成避雷器故障的主要原因是避雷器电阻片老化和质量问题,少数受污严重的避雷器在潮湿环境中也会发生闪络现象;造成避雷器重合不成功故障的原因是人为外力破坏、线路老化等。Taking the data of 10 kV distribution line fault of a power supply in the Pearl River Delta in 2010 as a sample,statistic analysis on main reasons of the line trips are carried out. The main reasons caused arrester failures are arrester valve aging and quality issues, and the flashover also may happened to a few seriously-polluted arresters in wet environment; the reasons of arrester unsuccessful trip coincides are man-made external damages and the aging of the line, etc.
