基于FBG传感的电子式互感器温度场监测研究
摘要
基于光纤Bragg光栅(FBG)测温原理
对电子式互感器内部温度从其工作时间为12 h和24 h两个时间段进行数据采集
并运用ANSYS仿真软件对内部采集的温度数据进行仿真分析
得出温度场分布云图
可知
电子式互感器上部沿着外壳边缘为温度最高处
中部两侧温度次之
下部温度最低
此时电子式互感器热点温度位于上部。随着电子式互感器工作时间延长
工作达到稳定状态
由于向外部环境散热
电子式互感器工作12 h时整体温度比工作24 h时高
两个时间段最热点温度分别为90.836
79.764℃。电子式互感器中部导体温度为电子式互感器整体最高。
Abstract
Based on fiber Bragg grating( FBG) temperature measurement principle
electronic transformer internal temperature data acquisition time from work is two time periods which are 12 h and 24 h
and collected its internal temperature data using ANSYS simulation software for simulation analysis
the temperature field contours obtained electronic transformer along an upper edge of the housing is the highest temperature at both sides of the central temperature is followed
the lower the minimum temperature at this time of the electronic transformer hot spot temperature in the upper part; electronic transformer with longer working hours
the work reaches a steady state
the heat with the external environment
and therefore the electronic transformer
when working 12 h a temperature higher than the overall work 24 h
the two time periods are the hottest temperature 90. 836 ℃
79. 764 ℃; the central part of the temperature of the electronic transformer electronic transformer conductor is highest overall.
