摘　　要：为了有效掌握复合绝缘子的运行状态,弥补现有检测手段的不足,在概述现有运行复合绝缘子的在线监测方法的基础上,分析了复合绝缘子故障的典型特点,提出了应力和温度是进行复合绝缘子运行状态在线监测的两个关键参量,制定了光纤布拉格光栅传感器应用于复合绝缘子芯棒应力和温度监测的技术途径。经多方协作研发,成功试制了在芯棒中植入了光纤传感器的复合绝缘子,并先后进行了实验室应力、温度传感特性试验和220 kV输电线路挂网试验。实验室试验结果证实了该技术的可行性,现场挂网试验表明基于该技术的智能复合绝缘子在线监测系统能够在现场环境下稳定运行,所监测的数据准确,有效弥补了现有检测手段的不足。Online monitoring methods and the fault types for running composite insulators were analyzed.To master online status of composite insulators and offset scarcity of existing monitoring methods,both stress and temperature were proposed as two key parameters of online monitoring the operating conditions of the composite insulators.The technical means which the optic fiber sensors were used to measure stress and temperature of the composite insulator mandrel were presented.After collaborative research and development,the composite insulators with optic fiber sensors embedded in the mandrel inclusion were produced,meanwhile,the 220 kV transmission lines linking network was tested.The technical feasibilities are fully confirmed by the experimental results,while the prospects and requirements of the next phase are also proposed,in order to optimize the technology platform.
