摘　　要：文章研究了国内外地线(含OPGW)4种组合接地方式,通过理论计算,OPGW采用单点接地或全线绝缘方式可大大降低电能损耗。采用一端接续塔OPGW全绝缘,另一端接续塔OPGW全接地的分段绝缘方案,可以结合使用普通OPGW接续盒和高压隔离绝缘光缆接续盒,技术经济性更优,对于输电线路节能降耗具有重要意义。This paper studied on grounding methods of four types of OPGW at home and abroad. Theoretical calculations show that OPGW can greatly reduce the power losses by using single point grounding or full insulation. With one OPGW end in the joint tower using full insulation and the other OPGW end in the joint tower using full grounding, combining with the advantages of normal OPGW joint box and high-voltage insulation cable joint box, this method has better technical-economical efficiency and is of great significance for energy saving and consumption reducing of power transmission line.
