Dianci bileiqi, 2015 内蒙古东部地区地理位置独特,能源丰富,输电线路担负着向外省输送电能的重要任务,线路里程长,地形地貌复杂,线路雷击风险较高。因此,有效提高输电线路防雷性能评估水平与治理能力,对保证蒙东地区供电的稳定可靠是十分重要的。本文基于差异化防雷技术开展蒙东地区输电线路防雷综合治理研究。具体来说,选择雷害严重的典型线路采用差异化防雷技术开展逐基杆塔的微观化防雷风险评估,评估时综合考虑线路走廊雷电活动、地形地貌、线路结构和绝缘配置的差异性;根据风险评估结果,结合各种防雷措施特点和已有改造经验,选择线路避雷器作为改造措施,

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 ...
