OPGW光缆防雷探讨

Discussion on lightning-prevention methods of OPGW optical cable

目前国内频繁发生OPGW架空地线复合光缆受雷击断股故障,已对电力通信造成了一定的威胁。如何提高OPGW耐雷水平,使OPGW更好地、可靠地应用值得我们探讨。本文从雷击造成OPGW光缆损坏的机理入手,详细分析了断股的原因,并说明了有效提高OPGW耐雷水平的基本措施,进一步提出了通过接地方式有效提高OPGW耐雷水平的方法。

Frequent OPGW optical ground fiber composite overhead ground wire damage from light strike have already exerted threats to some extent.It is worthy for us to research that how the level of OPGW coping with lighting strike is improved, so that OPGW becomes more reliable.In this paper,the reasons of thigh break are analyzed from the mechanism of damaging OPGW optical fiber cable resulting from the light strike and the necessary and basic measures how to decrease this kind of phenomenon are presented.In addition ,solutions of utilizing the ground are discussed to cope with this problem in a better manner.
