| 摘 要： | 减少避雷线的保护角或采用负保护角，在架空线路下架设耦合地线，在杆塔或避雷线上安装方绕击侧向针，在同塔双回线路雷击易击段的杆塔上均安装线路避雷器，可以采用差绝缘配置方案，其中一回线路采用并联间隙或线路避雷器进行防雷保护，另一回线路的绝缘水平适当加强或保持不变。

| Abstract: | Reducing the protective angle of shielding wire or using negative protecting angle. Coupling ground wire is mounted on transmission line. Lightning rod of side direction for shielding failure is fixed at tower or shielding wire. Lightning arresters is installed on easy- lightning strike part of double- circuit transmission lines on same tower, this is used by differential insulation scheme, one of double - circuit transmission lines is adopt by parallel gap or lines arresters, insulation level of another one is reinforced or maintained. |
