摘要
2001年茂名500kV变电站因雷击引起一次母线故障。此次雷击事故非常罕见,造成线路和母线同时发生故障。通过分析各种装置记录的故障数据和信号,对故障进行分析和推理,从而正确判断故障的性质,并且强调在数字式故障记录装置的条件下,如何更好地、更全面地采集故障数据,满足事故调查的技术要求。
This paper describes a bus failure on 500 kV JiangMao transmission line,which was caused by lightning strokes that led to line fault simultaneously. Based on the digital record of the fault and the signals of protection,an analysis is made and the nature of the failure determined.Furthermore,several pieces of advice are given on how to improve fault data collection to facilitate investigation of faults.
