摘要
提出了用小波分析和分形相结合求局部放电信号分维的方法。不同的局部放电信号 ,分维不同 ,故分维能用来识别局部放电信号 ,以便对局部放电信号进行相关处理 ,实验表明该方法能精确地识别声电信号 ,找出声电信号的对应关系 。
The paper presents a method to compute the fractal dimension of partial discharge with wavelet transform and fractal.Because the fractal dimension of different partial discharge is different,the fractal dimension can be used for identifying partial discharge signals and correlation processing The experiment results show that the method can identify accurately partial discharge signals and can find out corresponding relationship of electricity and ultrasonic signal,as a result of improving the locating precision.
