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和技术性能的分析,重点讨论了空气间隙、固定间隙和无间隙线路避雷器的优点和技术缺陷,为提高线路避雷器的可靠性,提出了一种新型的具有"免维护"功能的线路避雷器产品。Installation of line MOA is an effective measure for decreasing trip-out accident due to lighting stroke on overhead line,enhancing reliability of power supply and reducing service cost.The basic requirements for line MOA are described and assessment of their technical parameters and design aspects is presented with focus on advantages and technical drawbacks of MOA designated with air gap,electrode gap and gapless design.A new design of 'maintenance-free'line MOA is proposed for higher reliability.

关 键 词：线路避雷器 串联间隙 可靠性 免维护
