摘　　要：本文提出利用在线测量器身振动监测电力变压器铁心及绕组状况的方法 ;分析讨论了如何从器身振动信号中提取铁心及绕组的振动信号。根据参考文献以及实测得到的变压器器身振动信号频谱图 ,研究了铁心及绕组振动信号的基本特征 ;The method of measuring the tank vibration for on line monitoring the power transformer is described. How to extract the core's and the winding's vibration signals is also discussed and analyzed.According to the measured frequency domain characteristics of the tank vibration signals,we have described the feature of the core's and the winding's vibration signals.In conclusion,measuring the tank vibration to monitor the power transformer is more feasible than measuring the noise.
