摘　　要：针对咸阳供电局330 kV池桃Ⅱ线48号塔中相导线在大风时对铁塔曲臂放电的故障案例,通过对绝缘子串在工频电压、操作过电压、大气过电压等不同风速下的摇摆角及导线对铁塔构件的放电间隙校验等定量计算,找出了风害故障的原因,提出了加挂重锤来消除风害故障隐患的措施。文章可为架空输电线路专业人员从事防风害工作提供参考。In the light of the discharge towards tower cranks by middle phase conductor on 330 kV ChitaoⅡline No.48 tower in Xianyang Power Supply Bureau,through the quantitative calculation for the swing angle of insulator string with different wind speed and the discharge gap between conductor and the structure members of tower,the causes of fault caused bv wind damage are found out.Finally,a measure to eliminate the wind damage which is hidden troubles to overhead transmission line by suspending hammer on the insulator strings is proposed.
