| 摘 要： | 通过注入陡脉冲信号校验现场GIS特高频传感器的有效性会受到各种因素的影响。在GIS真型试验平台上开展了不同的典型缺陷与陡脉冲信号源所激发特高频信号的传播衰减特性对比分析，并应用小波包分析，对比分析了信号在不同频段的传播规律。试验结果表明：不同人工陡脉冲信号源会对检测结果产生较大影响，悬浮放电模型更加类似于人工陡脉冲信号源。通过注入陡脉冲信号对在运GIS的特高频传感器有效性开展验证，发现部分传感器存在问题。

| Abstract: | In this paper, the factors affecting the on-site calibration of GIS UHF sensors (ultra-high frequency sensors) are studied and compared. The characteristics of propagation and attenuation of UHF signals excited by different typical flaws and steep pulse sources are compared and analyzed on the real test platform of GIS. Then, the wavelet packet analysis is used to analyze the propagation rules of signals in different frequency. Finally, combined with the status of ultra high frequency sensors of GIS on site, the validity of the experiment is tested, and some problems are found to be defective. |

| Keywords: | UHF sensors field calibration wavelet packets analysis characteristics of propagation attenuation |
