摘要
分布式光纤测温(DTS)技术已经在电缆上得到应用,这为准确计算运行中电力电缆导体温度,掌握电缆真实载流量创造了条件。应用集中参数法的数学模型,推出根据电缆外护套温度计算导体温度的算法,对影响计算精度的因素进行了讨论。最后介绍了根据这种算法编制的软件的应用情况。
The technique of distributed temperature sensing （DTS） has found use in electric cables,which allows accurate calculation of the conductor temperature in power cables in operation and understanding of the real-time ampacity of the cable. We established a method for calculation of the conductor temperature from the sheath temperature by using a mathematic model of concentrated parameters and made discussions on the factors affecting the accuracy of the calculation. Finally, we introduced the application of a software based on this method.
