摘　　要：现有GIS设备局部放电监测多基于电学传感,感知数据来源单一、数据特征挖掘深度不足,感知数据无法准确表征局部放电发生、发展的内在特点及其变化规律,导致GIS绝缘故障的漏报率及误报率偏高。局部放电必然导致光、电、声、气体分解等物理现象的发生,文中分别介绍了局部放电光、电、声、气体分解等不同特征两点感知方法,在此基础上阐述了联合感知技术是未来发展方向,该方法可以获取GIS典型缺陷局部放电伴生的光、电表征信息,有助于更加全面掌握GIS局部放电发生、发展的内在规律,提升GIS绝缘状态评估的准确性。最后对上述研究的发展趋势进行了展望。The partial dischange(PD)monitoring of existing GIS equipment is mainly based on electrical sensing,the source of sensing data is single,the depth of data feature mining is insufficient,and the sensing data can not accurately characterize the internal characteristics and change law of PD occurrence and development,resulting in high missed and false alarm rate of insulation fault of GIS.The partial discharge will inevitably lead to occurrence of such physical phenomena as light,electricity,sound and gas decomposition.In this paper,the two-point sensing methods with different characteristics such as light,electricity,sound and gas decomposition of partial discharge are introduced.On this basis,it is expounded that joint sensing technology is the development direction in the future.This method can be used to obtain the light and electricity characteristic information associated with partial discharge of typical defects in GIS.It is helpful to more comprehensively master the internal law of occurrence and development of partial discharge in GIS and improve the accuracy of insulation state assessment of GIS.Finally,the development trend of the above research is prospected.
