摘　　要：我国大部分输电线路都架设有OPGW,OPGW断线将导致电力通信通道中断,会危及电力控制系统的正常运行,在冰灾多发地区,OPGW的融冰与导线和地线同样重要。文章讨论了3种OPGW热力融冰技术方案,提出一种在内部放置绝缘导线的OPGW结构,经检测,该结构的OPGW绝缘耐压≥9 kV,机械和光学性能满足设计要求,实际融冰效果有待在实际试验线路中加以验证。Most of transmission lines in China have the erected OPGW, breakage of the OPGW cable leads to the interrupted power communication channels, which will endanger the normal operation of power control systems. Thus, melting ice of the OPGW is the same important as conductor and ground wire in ice storm-prone areas. This paper analyzes and discusses three solutions of thermal melting ice technique for the OPGW, further proposes a structure of OPGW with built-in insulated wires. The testing results show that the insulation voltage resistance of the OPGW with the structure is more than 9 kV, and mechanical and optical performance meet the design requirements. The actual effects of melting ice remains to be verified in the actual transmission lines.
