| 摘 要： | 对于雷电活动强烈、地形复杂、土壤电阻率高的山区线路 ,采取各种传统综合防雷措施有时难以奏效。由于近些年 1 1 0 k V及以上电压等级的复合外套金属氧化物避雷器 (简称线路避雷器 )的研制成功 ,为解决线路的防雷提供了一种新的手段。从分流的角度 ,通过对雷击杆塔时 1 1 0 k V线路避雷器的仿真实验 ,在理论上分析了线路避雷器在输电线路防雷中的作用效果及其影响因素 ,指出了线路避雷器在实际运用中应该考虑的一些问题

| Abstract: | In some mountainous area where the lightning activates strongly and the terrain is very complex and the soil resistance is very high, it is difficult to have its enough efficiency in taking traditional protective measures against lightning discharges.These years, since metal oxide surge arresters for transmission lines(that is, line lightning arrester)was developed successfully, it has become one of new effective portective measure against lightning discharges.The EMTP program was used in imitating the process of 110kV lightning arresters against lightning discharges on transmission lines, analyzed the 110kVlightning arresters' protective effect.This paper also discusses some questions in applying the lightning arresters on transmission lines in practice. |
