Abstract:Under the impact of short-circuit current,the vibration characteristics of transformer is an important feature of vibration analysis method. To study this feature,firstly construct impact platform of influence of short-circuit current on transformer vibration,and then use this platform to study the distribution rule of correlation coefficient of transfer function and correlation coefficient threshold selection. On this basis,by waveform time-domain analysis and simulation research,explore the effects of winding short-circuit fault on transfer function,and finally study the relationship between the preload and the correlation coefficient,via the above study,define the relationship between the vibration characteristics of transformers under impact of short-circuit current,it laid the foundation for further analysis on transformer fault by vibration method.
Keywords:impact of short-circuit current  transfer function  correlation coefficient  preload  vibration analysis method
