【摘要】 介绍了一种光纤式复合绝缘子内部缺陷状态监测的新方法,利用埋植于复合绝缘子内的光纤光栅传感器现场检测其内部温度与应力的微小变化,从而可以判断其内部缺陷,通过在110 kV及220 kV线路上的挂网运行,可以实时监测复合绝缘子的运行状态。更多还原

【Abstract】 A new way of monitoring internal defects of fiber-optical composite insulator was introduced.The small changes in internal temperature and stress of the composite insulator were detected by using the fiber grating sensors implanted in it,so that the internal defects can be determined.The real-time operation status of composite insulator can be monitored through operating on 110 kV and 220 kV transmission line.更多还原
