摘　　要：针对OPGW雷击断股的特点和主要影响因素,通过模拟试验研究了综合防治措施。研究表明,新建线路中普通避雷线(GJ)应采用接地方式或提高布置高度,已建线路的GJ可多点接地或档距中间装放电尖等措施以降低OPGW雷击概率,同时选用耐雷型OPGW。最后论述了OPGW断股损伤后不同的处理方法。According to the characteristics and mainly influencing factors of the breaking of OPGW, synthetic prophylactico measures are researched in this paper. And we think that regular lightning shield conductor should be earthed differently or be raised to reduce the lightning probability of OPGW. Besides this, lightning-resostamt OPGW has been developed. Lastly, treatment measures for damaged OPGW are discussed.
