摘要
文章首先讨论了高压开关柜温度监测的意义及现有的几种测温方法,通过对几种测温方法的比较,介绍了光纤光栅测温法应用于开关柜测温的优势。文章设计了基于光纤布拉格光栅的开关柜温度在线监测系统,阐释了感知层、传输层和监控层3层系统结构,给出了光纤布拉格光栅的布设方式,最后设计了监控软件功能,并对需要解决的关键问题进行了研究。
In this paper the significance and several methods of high voltage switchgear temperature monitoring are discussed. Through the comparison of several temperature measuring methods, it introduces the advantages of using optical fiber grating temperature measurement method in switchgear monitoring. The paper designs an on-line monitoring system for the switchgear based on optical fiber Bragg grating （FBG）. It explains the system structures of sensing layer, transport layer and monitoring layer and gives the layout way of the FBGs. At last, the paper designs the functions of monitoring software and discusses the key problems needed to be solved
