分布式光纤测温技术在高压电缆中的应用

Application of distributed optical fiber temperature measurement technology in high voltage cable

介绍了分布式光纤温度测量系统的工作原理和应用现状,分析了载流量和温度数据关系。以呼和浩特市名都房产区段电缆改造工程的应用为实例对系统进行了检测。实测结果表明,该系统能准确测量电缆所在区域的温度,也能对载流量进行动态评估和预测,为电网运行安全提供了极大的保障。

Working principle and application status of distributed optical fiber temperature measurement system （DTS） are introduced briefly in this paper, the relationship between carrying capacity and temperature data is analyzed. Power cable reconstruction project in Hohhot Mingdu estate section is took as an example of DTS＇s application. The test results shows that the system can not only accurately measure the temperature of the cable area, but also carry on the dynamic assessment and prediction of the carrying capacity. It provides great protection for the safety operation of the power grid.
