| 摘 要： | OPGW光缆在作为电力系统的重要组成部分时，兼具了架空地线和光缆的双重功能，在电力系纲中起着防雷保护和传输信息的作用。但在作为架空输电线路的避雷线时，OPGW光缆遭到雷击的事故在所难免，而且易出现雷击后的断股断芯现象，这给信息传输作用的担纲构成严重威胁。文章通过对OPGW光缆雷击断股现象和雷击断股机理的分析，对如何提高OPGW光缆的耐雷水平做了一些探讨乖研究。

| Abstract: | OPGW is an important element of power electrical system. It is not only used as ground wire for protecting transmission line against lighting strike, but also used as a fiber optic cable to transmit information. When OPGW is used as the lightning conductor of electric power transmission line, the phenomenon of striking by lightning is unavoidable, and it often causes the OPGW core break, and these accidents have threatened the normal information transmission seriously. In this article, the reason of lightning-caused OPGW strand breakage is analyzed, and the methods for improving OPGW performance against lighting strike are discussed. |
