Abstract

In order to overcome the blindness of the installation of sensors in monitoring the vibration of the transformer, in this paper, a method for monitoring the DC bias of transformer based on the amplitude of the iron core is proposed. By establishing the circuit electromagnetic field force field model, a finite element analysis is used to obtain the vibration amplitude of the DC magnetic field at each position of the transformer core, then to collect the low frequency vibration of the core during the operation of the transformer. Analysis of the data and timely warning, can improve the accuracy of the vibration signal acquisition, to avoid the DC bias due to abnormal vibration of the transformer and accident tripping and other major accidents.
