超声波、特高频局部放电联合定位方法的应用研究

摘要

将GIS设备带电检测方法和故障定位技术相结合,通过500 kV GIS设备内部局部放电定位实例,验证了超声波法和特高频法联合定位的可行性、适用性.现场应用情况表明,两种方法相结合,能对GIS设备缺陷进行准确定位,为GIS设备安全运行提供有力保障.%This paper introduces the live detection method and fault location related technology of GIS equipment,and combines two detection methods.Through the example of partial discharge location in 500 kV GIS equipment,the feasibility and applicability of the combination of ultrasonic method and UHF method are verified.The field application shows that the combination of two methods can accurately locate the defects of GIS equipment,and provide a strong guarantee for the safe operation of GIS equipment.
