摘要
从传感器、超高频信号的采集处理、信号的模式识别及超高频信号的标定等几个关键技术出发,对超高频法在电力设备局部放电在线检测中的应用现状进行了综述,并对超高频法在实际应用中存在的问题进行了探讨。最后,展望了超高频局部放电在线检测技术的发展前景。
The key techniques about the sensing, data acquisition and processing, pattern recognition and calibration of ultra- high-frequency (UHF) signals are illuminated and the present status of field applications of on-line UHF partial discharge (PD) detection method is summarized in this paper. Several problems of UHF PD detection method in practical utilizations are analyzed, At last the future prospect of this technology is further discussed.
