摘要
研究电晕放电辐射信号既有利于消除其危害又有助于加强对其利用。针对小波变换提出在不同情况下对不同类型的电晕放电进行分析时,选取小波基函数的方法,理论上可以通过信号与小波波形的匹配或者通过计算信号与小波相关系数的方法来确定,而在不确定放电类型时可进行实际分析。
It is advantageous to remove its harm and to utilize in strengthen as to it's exploitation for studying the corona discharge radiation signal. The wavelet transform technique is an efficient way to analyze the corona discharge radiation signal. This paper aims at the method of selecting the best wavelet function under different circumstance to analyze different type of corona discharge by wavelet analysis : In theory , the best wavelet function can be selected by matching the signal and the wavelet or by computing the related coefficient of the signal and the wavelet, while the indeterminable discharge be analyzed actually.
