Scope

本文件适用于交流1 kV以上架空输电和配电线路用带外串联间隙金属氧化物避雷器（以下简称带外串联间隙线路避雷器，EGLA），仅保护线路绝缘（包括绝缘子和空气间隙）免受雷电引起的闪络或击穿。
由于EGLA的金属氧化物电阻片通过外串联间隙连接到线路上，下面的问题将不在本文件中考虑：
——操作冲击放电电压；
——陡波和操作冲击残压；
——热稳定；
——长持续电流冲击耐受；
——避雷器工频电压耐受时间特性；
——脱离器试验；
——工频电压引起的老化。
对于避雷器本体与间隙一体化设计、无法拆卸的带外串联间隙金属氧化物避雷器部分性能要求、试验方法在本文件中并未考虑，因此本文件不适用于该类避雷器。经供需双方同意，该类避雷器的技术要求参照本文件的部分内容执行，但还要额外考虑本文件对于该类避雷器性能未考核的内容。
