摘要
介绍了110kV隆高898线多次因雷击跳闸的情况并分析跳闸原因,指出该线路35号长江大跨越塔C相避雷器为故障点。结合现场情况提出了恢复线路大跨越段避雷线的线路防雷保护调整方案,调整后的线路运行正常,没有出现雷击跳闸情况。建议在线路运行工作中应加强对线路避雷器的检测。
Based on the introduction of multiple lightning tripping accidents and the cause analysis of tripping for 110 kV Longgao 898 transmission lines,the fault point of C-phase arrester on the 35# large crossing tower over the Yangtze River is pointed out in this paper.The adjustment scheme of line lightning protection,which was to restore the overhead grounding wires,was put forward combined with the site situation.The results show that the transmission line after the adjustment run normally.Therefore,it is suggested that the arrester monitoring in transmission lines management should be strengthened.
