Research and analysis of winding short circuit fault of rectilinear phase shift transformer rectifier system

In order to study the fault characteristics of linear transformer in rectifiers of linear phase-shifting transformer, two kinds of short-circuit faults between winding Bridges and internal winding disconnection faults are analyzed by Ansys simulation and prototype test. Winding short-circuit fault between bridge including the same bridge, the bridge between the winding and different bridge bridge between winding short-circuit two types, the original edge input current is obtained by simulation experiment, vice side output voltage, twelve phase winding unit of phase current waveform simulation and experiment, and the electrical characteristics for Fourier analysis, concluded under the interphase short circuit fault feature, and the internal winding circuit fault simulation test, The corresponding characteristics of winding break fault are summarized. It is of certain significance to study and analyze the characteristics of the device under two working conditions.
