摘　　要：输电线路覆冰威胁着线路稳定运行。现有覆冰在线监测装置监测传感器为有源器件,信号传送均为电信号传输,易受到电磁干扰且装置工作稳定性较差。笔者设计了一种基于光纤布拉格光栅传感器的输电线路在线覆冰监测装置,并在110 kV震走线44号塔进行了挂网试运行。试验结果表明,研制的光纤布拉格光栅传感器单元线性度高,灵敏度较好,覆冰在线监测装置运行稳定,监测数据准确。Ice accretion has been a huge threat for the stable operation of transmission line. At present, all the online monitoring devices of icing use active sensors, and the working stability is low. Signals are transmitted in the electrical form, which are easily affected by the electromagnetic interference. In this paper, an online monitoring device of transmission line icing based on fiber bragg grating （FBG） sensor is designed,and is operated as a pilot unit on the 44# tower of 110kV Zhenzou line. Experimental results show that the online icing monitoring device operates stably, and the designed fiber bragg grating sensor has high linearity, good sensitivity and high accuracy.
