摘要
提出一种用于气体绝缘封闭组合电器金属颗粒放电的检测方法。利用超声波局部放电检测的图谱分析、幅值法定位和频率法定位,结合特高频局部放电检测、SF6气体湿度和成分分析,以实现GIS设备的带电检测和综合诊断,为GIS设备状态的精确评价提供可靠而有效的参考。
A method for detecting metal particle discharge in gas-insulated metal-enclosed switchgear(GIS )is proposed.The method combines with ultra-high frequency partial discharge detection,SF6 gas humidity and component analysis,meanwhile it makes use of the atlas analysis,the amplitude localization and the frequency localization of ultrasonic partial discharge detection.The proposed method can realize the live detection and can comprehensively diagnosis of GIS equipment,providing reliable information for the accurate evaluation of GIS equipment status.
