摘　　要：跌落式避雷器是将带脱离器的避雷器和跌落式熔断器相结合,除具有传统型避雷器的过压保护外,在发生异常故障时,工频短路电流使脱离器动作,其接地端自动脱开,可防止事故的进一步扩大,检修维护更为方便;介绍了跌落式避雷器在武铜6kV供电线路中的应用和维护注意事项,提高线路供电的可靠性。The drop arrester is a combination of detachable arrester and drop type fuse.In addition to the over-voltage protection of traditional arrester,in case of abnormal fault,the power frequency short-circuit current makes the detachable move,and the grounding end automatically detachable,which can prevent further expansion of the accident and make maintenance more convenient.This paper introduces the application and maintenance precautions of drop arrester in 6Kv powder supply line to improve the reliability of line power supply.
