摘　　要：对某风电场110kV架空线路跳闸原因进行了分析,确定为110kV线路某段交叉跨越35kV集电线路处,受地形、强风、雷电、温度、湿度等特定因素叠加影响,交叉跨越处导线发生风偏,导致上下导线电气间隙不满足安全距离,产生风偏放电现象,保护动作跳闸。从风电场运维角度分析了跳闸故障的现象及原因,提出整改措施,降低了此类故障再次发生的概率。An analysis was conducted on the cause of the tripping of a 110 kV overhead line in a certain wind farm,and it was determined that at a certain section of the 110 kV line crossing over a 35 kV collector line,the wire at the crossing was affected by specific factors such as terrain,strong wind,lightning,temperature,and humidity.The wind deviation occurred in the wire at the crossing,causing the electrical gap between the upper and lower wires to not meet the safe distance,resulting in wind deviation discharge and tripping of the protection action.This article analyzes the phenomenon and causes of tripping faults from the perspective of wind farm operation and maintenance,and proposes rectification measures to reduce the recurrence of such faults.
