对电力系统OPGW光缆防雷接地技术的探讨

摘要

在电力通信中,OPGW光缆起着至关重要的作用。近年来,天生桥二级电站所辖OPGW进站通信光缆频繁出现遭受雷击或电网过电压间隙放电情况,导致OPGW光缆导线断股纤芯中断故障,对电站通信业务的传输造成了极大的威胁。如何提高OPGW光缆的防雷水平,让OPGW光缆安全可靠地为电力通信服务,这是值得我们探讨的问题。本文从雷击造成OPGW光缆损坏的机理入手,分析了OPGW光缆断股的原因,阐述了OPGW光缆防雷水平的改进措施,进一步提出了通过良好接地方式有效提高OPGW光缆防雷水平的方法。%In the electric power communication, OPGW （：able plays a vital roleo In recent years, TianShengQiao level 2 power station and communication optical cable OPGW pit stop frequent shock or grid discharge gap over voltage, cause OPGW cable condnctor broken stocks fiber core interrupt fault, of power station communications business transmission cause great threat.oHow to improve the level of lightning protection OPGW optical cable, optical cable for OPGW reliable for electric power communication services, this is worth us of discussion This paper, ofrom the lightning strike damage mechanism of the OPGW fiber optic cable, analyzes the reasons of the broken stocks OPGW fiber optic cable, this paper expounds the OPGW cable improvement measures oflighming protection level, and further puts forward through the good way to effectively improve OPGW cable grounding method of lightning protection level.
