摘　　要：青海省海东地区属多雷区,输电线路多分布在高土壤电阻率地区,降低杆塔接地电阻尤为重要,可控放电避雷针是近年输电线路防雷的新设备,2005年应用于海东供电公司。文章介绍了可控放电避雷针防雷的原理,并对挂网运行的可控放电避雷针进行了跟踪统计,阐述了可控放电避雷针的选型及安装维护,对其的防雷效果进行了评估。Haidong areas of Qinghai province locates in thunder region, and most of its transmission line distributes on high earth resistivity areas, thus grounding resistance decrease becomes especially important, controlled discharge lightning rod is a newly - used equipment in transmission line lightning protection in recent years, and it has been adopted in Haidong power supply company since 2005. The paper introduces the principle of lightning protection of controlled discharge lightning rod, and makes a tracing statistics of the operating above - mentioned lightning rod, therefore expounds its type selection, installation and maintenance, as well as makes a evaluation on its lightning protection effect.
