Gaoya dianqi35 kV风电场架空集电线路多位于山岩地区，雷击跳闸率高，需要相应的防雷措施。目前，在山岩地区降低接地电阻困难，成本高，接地电阻值难以达标。文中研究了35 kV风电场架空集电线路的等效降阻防雷措施。结果表明，架设耦合地线时，耐雷水平可以达到接地电阻为5Ω时的水平；当35 kV集电线路安装线路避雷器时，雷击避雷线GJ-100、雷击避雷线OPGW、雷击导线时耐雷水平的提升幅度分别为8.23、7.86、70.8倍，对比降低接地电阻有更显著的提升效果。该研究将在35 ...

Dianci bileiqi, 1991 叙述了测量系统的发展。该系统采用了快速响应抗干扰光电传感器。影响输电线路运行的主要雷害事故是杆塔电压升高通过绝缘子反击。为了预防雷电反击事故并进行保护,需要很好地了解雷电反击的机理,包括杆塔顶电位升高、杆塔电位分布、招弧角放电特性等,这就使理论分析很困难。最好的办法是测量雷电实际波形,但由于电压高,波头短 ...
