Rezumat | ||||||
The model for three-phase three legs phase-shifting transformers is realized, calculations and research of steady state asymmetric modes particularities were fulfilled, taking into account the electromagnetic coupling of the windings, located on different legs. Calculations and analysis include the most characteristics steady state asymmetric modes that occur during different short circuits and other asymmetric modes, including ones, associated with the occurrence of zero sequence magnetic flux. For the considered modes vector diagrams for currents and voltages were constructed, as well as for the relative values of magnetic fluxes in legs, which in ensemble give a clear idea about their particularities. Obtained results could be used for the design of phase shifting transformers for estimation of winding insulation requirements, electromagnetic forces at short circuits, etc. |
