摘要
介绍了变压器运行中有载分接开关振动信号的分离提取方法,然后分析了几种方法的优劣,最后通过实验证明了小波分析方法提取有载分接开关振动信号的可行性.
The separation and extraction method of on-load tap-changer vibration signals in transformer operation is introduced, and the advantages and disadvantages of several methods are analyzed, and finally the feasibility of wavelet analysis to extract the on-load tap-vibration signals is proved by the entity experiment.
