摘　　要：雷雨天气配电线路自保跳闸,重新合闸后一切正常的特殊故障比较少见。基于某污水处理厂雷雨天气线路跳闸事故原因分析,介绍了目前民用10 kV/380 V动力、照明线路存在的过电压(流)事故隐患及其危害原理剖析,并提供经过实践验证的解决方法。It is rare that everything is normal after re-closing,when the power distribution line trips during the thunderstorm weather.Based on accident analysis of line trip in wastewater treatment plant during thunderstorm weather,the hidden dangers of over-voltage(current) accidents and its hazard principles for civil 10 kV/380 V power and lighting lines were discussed.The solutions that have been proven in practice were provided.
