2.5mm, 该单模光纤为单模 G.652光纤, 该多模光纤为多模 G.651光纤。 优选地, 该单模光纤的数量为 20根, 该多模光纤的数量为 4根。 为保证光纤在导线运行中不受拉伸, 该不锈钢套管光纤单元中的光纤应用一定的 余长, 例如, 该单模光纤和该多模光纤的长度可以大于该支撑线的长度。 本发明实施例提供的混模测温通信相导线可以包括中心层、 第一层、 第二层、 第 三层和第四层, 优选地, 中心层为 1根直径为 2.5mm的 14%AS 线, 用于承受导线中 张力, 第二层为 5根直径为 2.5mm的 14%AS 线, 用于用于承受导线中张力, 以及不 锈钢套管光纤单元, 用于通信及测温, 第二层为 10根直径为 3.22mm的铝线, 用于输 电, 第三层为 16根直径为 3.22mm的铝线, 用于输电, 第四层为 22根直径为 3.22mm 的铝线,用于输电。其中, 14%AS主要承担耐张力作用,铝线主要承担电流输送作用,
不锈钢套管主要承担 24芯的光纤束的机械保护作用, 避免运输、施工、运行中压伤光 纤。 本发明实施例中的测温通信系统可对高压输电线路导线进行实时全程逐点温度监 测, 采集连续测量信息, 配合三点全断面接触式测温, 可实现输电线路三相导线温度
本发明实施例中的测温通信系统依据拉曼反射原理进行温度测量与定位。 拉曼反 射是指激光器向光纤发射光脉冲, 有一部分光会在光纤中形成后向散射光和前向散射 光, 经定向耦合器收集后向散射光送至光电检测系统进光强度、 延时分析。 反射点的 温度 (该点光纤的环境温度) 越高, 反射光的强度也越大, 然后对定向耦合器收集到 的后向散射光进行反射光的强度和延时分析, 依据经验模型可以计算出反射点的温度 和位置。 由于多模光纤比单模光纤反射更强, 因此测量精度更准, 因此采用多模光纤 测温、 单模光纤通信, 将单模与多模混合在一起, 通过色标环区分, 构成混模光纤技 术。 本发明实施例提供的一种测温通信系统, 通过设置单模光纤通信, 通过多模光纤 测温, 实现了可以对导线进行全程测温。 以上所述仅为本发明的优选实施例而已, 并不用于限制本发明, 对于本领域的技 术人员来说, 本发明可以有各种更改和变化。 凡在本发明的精神和原则之内, 所作的 任何修改、 等同替换、 改进等, 均应包含在本发明的保护范围之内。
