摘要
光纤复合架空相线(OPPC)具有输电和通信双重功能,在老线路更换一相导线为OPPC光缆的工程中,新架设的OPPC光缆应与另外两相导线电气性能和机械性能相匹配,载流量、弧垂值两个重要参数应基本一致。通过计算OPPC光缆的载流量、弧垂值与老线路导线相比较,分析OPPC光缆更换原线路导线的合理性。
The optical fiber composition phase conductor(OPPC) has dual functions of transmission and communication.In the project of replacing one phase conductor with OPPC fiber cable,the newly erected OPPC fiber cable shall match with the electrical and mechanical properties of the other two phase conductors,and the two important parameters of carrying capacity and sag value shall be basically the same.By calculating the carrying capacity and sag value of OPPC fiber cable and comparing with the original line conductor,the rationality of OPPC fiber cable replacing the original line wire is analyzed.
