摘要
高压电缆敷设后工作时产生的温度是否正常,是关系到电力系统安全的重要问题。本文对采用光纤技术的电缆测温原理和技术进行探讨,分析比较了几种常见的测温方式,认为采用基于光时域反射(OTDR)技术和拉曼效应的分布式光纤温度传感系统具有较大的应用前景。
The temperature status in the installed high voltage cables is a critical issue assoclateo wlm me security of power systems. This paper discusses the temperature measurement principle and technology in cables using optical fiber technology, analyzes and compares several common temperature measurement methods. It is considered that the distributed optical fiber sensor system based on OTDR and Raman effect is a promising scheme.
