摘要
分布式光纤温度传感技术是一种用于实时测量空间温度场分布的传感技术。该技术利用光时域反射原理、激光喇曼光谱原理,经波分复用器、光电检测器等对采集的温度信息进行放大并将温度信息实时地计算出来,它能对光纤测线的温度场进行分布式的连续检测,是实现实时测量空间分布温度的一种新技术。本文介绍了该技术的测温原理以及其在南昌电网110 kV高压电缆隧道在线监测中的应用。
The distributed optical fiber temperature sensing technology is a kind of technology for real time measuring the interspace temperature field distributing. It uses optical time domain reflectometry principle,laser Raman spectrum principle, through again using equipment, optical electric examining equipment, it magnifies the collecting temperature information and then figures out,it can inspect distributely and continously to the optical fiber wire＇s temperature field. It＇s a new kind of technology for real time measuring temperature. This paper introduced its measuring temperature principle and using for the Nanchang power grid project.
