| 摘 要： | 高温和火灾是电力系统中常见的事故,缺乏有效的温度在线监测是关键.传统的测温装置无法满足对温度的远距离、多点、实时的温度在线测量.而分布式光纤测温系统的研制有效地解决了这些问题,其对温度分辨率高,定位准确,响应时间短,可明显地降低事故发生率.主要介绍了基于喇曼散射的分布式光纤测温系统的基本原理、传感过程及其如何应用在电力系统的各个环节,真正实现了电力系统温度监测与报警自动化,为整个电力系统的安全运行提供保障.

| Abstract: | High temperature and fire are ordinary accidents in electric power system and lack of the effective on- line monitoring of temperature is the key.Traditional temperature sensor can not content the need of real-time measure which is provided with the merits of long-distance,multi-points and on-line.But the development of distributed optical fiber temperature system can resolve these problems effectively.This system has the characteristics of high temperature differentiate,exactly locating and short response time,so it can reduce the frequency of accidents obviously. This article mainly introduced the basic theory and sensor process of distributed optical fiber temperature sensor system based on Raman scattering,and how to be applied in the parts of electric power system.It realized the automatization of temperature monitor and alarm in electric power system,ensuring entire electric power system operating in security. |
