摘要
从绝缘导线雷击断线机理分析入手，介绍了环形电极和穿刺电极两种带外串联间隙金属氧化物避雷器解决雷击断线问题的工作原理，阐述了绝缘导线雷击断线防护措施，提出了在变电所10kV侧设立长度约1～2km的进线保护段方案。
Based on analysis of mechanism of insulating conductor broken by lightning stroke, working principle of two kinds of metal-oxide arrester with external series gaps which were used to solve the problem of line broken by lightning stroke were introduced. The protection measures were presented. A plan to install a 1 to 2 km inlet line as protection at 10 kV side of substation is put forward.
