摘要
针对某现场运行的超高压线路OPGW频繁断股的问题,通过对该OPGW样品的理化性能、雷击性能、短路电流性能等的试验与分析,结合该线路运行情况,得出该OPGW断股由雷击造成,而该OPGW本身耐雷性能较差。
For frequent OPGW strand breakage of an EHV transmission line,the physical and chemical properties,anti-lightning performance,and short-circuit property are tested and analyzed.Considering the operation condition of the transmission line,conclusion can be drawn that the strand breakage of the OPGW is caused by lightning,and anti-lightning performance of the OPGW is weak.
