摘　　要：2020年雷雨季节某地区10 kV配电线路避雷器出现大面积炸裂故障,给电网运维检修工作带来了较大压力。为全面分析故障原因,从地区落雷情况、故障与正常避雷器解体比对、诊断试验、理论推理等角度深入分析,发现避雷器产品质量不合格是造成大面积故障的主要原因,对后续工作提出了防范建议和措施。In the thunderstorm season of 2020,the arrester of the 10 kV distribution line in a certain area has a largescale burst failure,which has brought great pressure to the operation and maintenance of the power grid.In order to comprehensively analyze the cause of the failure,we made an in-depth analysis from the perspectives of lightning strikes in the region,comparison of the breakdown with normal arresters,diagnostic tests,and theoretical reasoning.Recommendations and Actions.
