摘　　要：山区配电线路运行易受雷击影响。炎陵地区86.9%为山地,近年该地区雷电活动频繁,使得10 kV架空线路故障概率大幅提升,因此以10 kV架空线路月霞线为例,建立ATP线路仿真模型,研究避雷线、避雷器、接地电阻对架空线路耐雷水平的影响,并提出提升线路耐雷水平的具体措施。The operation of distribution lines in mountainous area is easily affected by lightning stroke.86.9% of Yanling area is mountainous.In recent years,lightning activity has been frequent in this area,which greatly increases the probability of failure of 10 kV overhead lines.Taking Yue xia line of 10 kV overhead line as an example,the ATP-EMTP line simulation model is established to study the influence of shielding wire,lightning arrester and grounding resistance on lightning withstand level of line.Finally,Concrete measures are put forward to improve the mine resistance level of the line.
