摘要
近期,在我国OPGW+GW的双地线系统中OPGW频繁遭雷击断股,与之配合的另一条(GJ-80、LHBGJ-95/55、LGJ55/95)地线却相安无事,在分析OPGW断股和遭受雷击断股的基础上,讨论了各种造成OPGW断股和遭受雷击断股的因素;指出OPGW的断股有人为质量隐患因素(断1股为例)和自然灾害雷击所致(以断多股为例)2类。最后指出OPGW雷击断股的核心问题是结构设计问题,为此提出了科学的论证和切实可行的解决方案及措施。
Since recently often happen break strand after OPGW ＋ CW been strike by lighting in double earth wire system in our country, but the another suitable wire （GJ-80, LHBGJ-95/55, LGJ-55/95）be nothing, the article analysis practice case of break streak and be strike by lighting , and discuss its reasons , and then to point out that this is caused by construct design based on followings ; there are two types of break strand ： the caused by its quality （ for the sample of single break strand） and by lighting （ for the sample of poly break strand）, and then to refer a scientific argument and cogent save plan.
