摘　　要：绝缘子带电检测是线路运行维护中的重要工作之一。提出了一种基于光纤电场传感器的绝缘子检测方法;并研究了相应的检测装置。运用该检测装置,首先测量绝缘子表面纵向场强,绘制场强分布曲线;然后,根据电场法并利用曲线分布规律检测出劣化绝缘子。现场试验与分析表明,该装置具有频率响应宽、绝缘性好、测量精度高等特点。Insulator detection is one of the important works in operation and maintenance of Transmission Lines. Faulty Insulator detection method and device based on optical electric field intensity senor were introduced. Firstly, the insulator surface longitudinal electric field was measured; then, field intensity distribution curves were drawn by professional software; then, faulty insulator was detected by analyzing the drawn curves according to the electric field method. Field test and analysis show that the detection device is of wide frequency response, good insulation and high measuring accuracy. ~
