| 摘 要： | 韶关电厂至郭塘变电站的２２０ｋＶ输变电线路大部分杆塔地处粤北山区，雷电活动强烈，常发生雷击跳闸故障。为此，选择在韶郭线雷电易击段安装氧化锌避雷器的方法，来提高线路的防雷性能。通过雷电定位系统的分析比较，安装氧化锌避雷器后，线路跳闸次数明显下降，事实证明这种方法的防雷效果较好。

| Abstract: | The 220 kV transmission line from Shaoguan Power Plant to Guotang Substation is mostly located in mountain area, and had lightning trip out failures quite often due to the intense lightning activities. As a result, ZnO arresters are adopted on trouble spots to enhance the lightning protective performance of the line. Analytical comparison through lightning location system shows the good effects of ZnO arresters on lightning protection. |
