摘要
电气设备在日常运行中经常会发生局部放电的现象,这主要与其内部绝缘材料的劣化和绝缘体的击穿有着密切的关系,因此需要准确、快速地判断局部放电的位置及类型,并积极的采取措施避免扩大故障范围。文中将在分析局部放电特性的基础上,研究了氮气设备局部放电信号的特征提取以及分类方法供相关维护人员参考。
Partial discharge often occurs in electrical equipment during daily operation,which is mainly related to the deterioration of its internal insulating material and the breakdown of the insulator.Therefore,it is necessary to accurately and quickly determine the location and type of partial discharge,and actively adopt measures to avoid expanding the scope of the fault.Based on the analysis of the characteristics of partial discharges,this paper studies the feature extraction and classification methods of partial discharge signals of nitrogen equipment for reference by relevant maintenance personnel.
