摘　　要：利用光纤Bragg光栅(FBG)温度传感器设计出一种无线测温系统。经过现场实验得到了电抗器测量包封层6 h温度变化曲线。结果表明:该系统能够全方位地反映内部温度分布情况,判断温度变化趋势和确定异常温度点的具体位置,为及时发现故障和保证电抗器稳定可靠运行提供了重要参考。Aiming at difficult problem of reactor temperature detection, a kind of wireless temperature measurement system is designed by using fiber Bragg grating（FBG） temperature sensor. Temperature change curve of reactor wrappage for 6 h is obtained by experiment. The results show that the system can fully reflect internal temperature distribution, judge trend of temperature change and determine specific location of abnormal temperature point, provide important reference for the timely detection of failures and to ensure stable and reliable operation of the reactor.
