摘要
加装线路避雷器是减少线路雷击跳闸事故,提高供电系统可靠性,进一步降低运行成本的一种有效的手段。根据供电线路的实际情况,笔者阐述了线路避雷器的基本要求,通过对目前国内线路避雷器的结构类型、技术性能和运行情况的分析,重点讨论了空气间隙、固定间隙和无间隙不同结构线路避雷器的技术特点和优缺点,提出了一种具有“免维护”功能的新型线路避雷器。
The additional installation of line-type surge arrester is an effective means for reducing the accidents of transmission line caused by lightning strike and enhancing the reliability of power system, and lowering the operation cost. This paper introduces the basic requirements of line-type surge arrester, the technical features of various arresters with different structure. Then, a new type of product with maintenance -free function is presented.
