摘要(Abstract)：

UHF法作为一种抗干扰性能佳、灵敏度高、易识别缺陷类型以及可实现放电源定位的局部放电检测方法,在GIS绝缘缺陷和故障诊断中有着良好的应用前景。通过介绍近年来GIS局部放电电流特性、UHF信号传播特性、UHF传感器设计与测试、诊断与评估技术等方面的重要研究成果,讨论了UHF检测盲区、幅值量化标定、危险度评估等目前在研究和实践中存在的问题,提出了今后GIS UHF技术的研究与应用发展方向。
As a partial discharge(PD) detection method, the ultra-high frequency(UHF) detection method has been widely accepted due to its good anti-interfere performance, high sensitivity, capability of defect type recognition and PD source location. By introducing PD current characteristics of GIS, UHF signal transmission characteristics, UHF sensor design, test, diagnosis and detection technologies, the paper expounds their key research achievements in recent years and discusses problems in ongoing dead zone of UHF detection, amplitude quantization and calibration as well as risk level evaluation; moreover, it presents the research and application direction of UHF detection technology of GIS.
