摘要(Abstract)：

GIS（气体绝缘封闭组合电器）内微水含量升高会降低其绝缘水平。为了实现对GIS内部绝缘气体湿度的在线监测，设计了一种基于双锥微纳光纤的GIS湿度传感器。首先采用BPM（光束传播法）对双锥微纳光纤的光场进行仿真，研究双锥微纳光纤的光场分布与模式干涉理论，得到SF6气体随微水含量的变化规律；然后采用熔融拉锥法制备了双锥微纳光纤湿度传感器，并进行了湿度传感实验。最后结合实验得出结论，基于双锥微纳光纤的湿度传感器检测灵敏度为-51.75 pm/%RH，能够实现对电气设备湿度的连续在线监测。
An increase in moisture content within GIS(gas insulated switchgear) can compromise its insulation integrity. To monitor insulation gas humidity inside GIS, a humidity sensor using dual-cone microfibers is developed.Firstly, utilizing beam propagation method(BPM), the optical field of the dual-cone microfibers is simulated to investigate their field distribution and mode interference theory. This analysis reveals the correlation between SF6 and moisture content. Subsequently, the fused biconical taper(FBT) is used to fabricate the dual-cone microfiber humidity sensor and conduct humidity sensing experiments. Based on the experimental data, it is determined that the humidity sensor using dual-cone microfibers exhibits a detection sensitivity of-51.75 pm/%RH, enabling continuous online monitoring of humidity levels in electrical equipment.
