| 摘 要： | 讨论八种常用连续小波变换检测强载波干扰中局放信号的效果，并对如何正确选择小波进行了分析。仿真结果表明，采用合适的连续小波及伸缩因子既可对局放信号进行特征提取，又可对强载波干扰信号进行抑制，因此应用合适的连续小波变换检测强载波干扰中的局放信号是可行的。

| Abstract: | In this paper the detecting effect of partial discharge using eight common types of continuous wavelet transform (CWT) is described and how to choose suitable wavelet correctly is analyzed. Simulation result shows that the feature of partial discharge can be extracted and the strong carrier disturbance can be restrained by use of appropriate CWT and scaling factor. Thus, it is suitable to detect partial discharge in strong carrier disturbance with appropriate CWT. |
