Analysis of Fault Detection of Power Transformer Based on Vibration Signal Analysis Method
According to the fault diagnosis and positioning method of transformer,the transformer fault diagnosis technology based on Vibration Analysis method is discussed.The technique involves the principle of core and wind-ing vibration,and the influence of mechanical structural changes on frequency concentration and vibration stability.Through the mutual information method,the precise positioning of the fault position has been achieved.The ex-periment shows that the Vibration Analysis method can not only provide a comparable or better detection accuracy than the traditional method,but also has the advantages of non-invasive and real-time monitoring,which is an im-portant means of power system maintenance and fault prevention.
