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。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.
