浅谈分布式光纤感温线预警系统新技术在变电站中的应用

分布式光纤温度传感系统是一种利用激光在光纤中传输时产生的背向喇曼散射信号和光时域反射原理来获取空间温度分布信息的监控系统,其核心技术采用了先进的激光、电子技术、高速DSP数据处理技术和先进的WDM光学波分技术及卫星拍照数字处理等技术。本文结合目前日益发展的电力系统建设以及对其越来越高的技术、信息方面的要求,浅述一下分布式光纤感温在线预警系统在变电站中的应用。

Temperature detected by distributed optical fiber sensor-based system is a monitor and control system which used the scatter and reflect by laser transmitted in fiber, and gained the information of temperature distributing in space. The kernel technology used advanced laser、electronically technology、high speed DSP data processing technology、WDM optical and satellite photograph technology, etc. This article aim at the present electric power system, with increasingly development and better and better needed in technology and information field, to simply analyzed the application of this system on transformer substation.
