Abstract

In contrast to the DC and single-phase AC electric traction systems existing on the electrified railways of the world, in the developed three-phase electric traction system, when one phase of power supply (one of two wires of contact network) is switched off, it becomes necessary to switch three-phase equipment of electric rolling stock, in particular six-pulse bridge rectifiers, into the partially phased mode. In this connection, the features of six-pulse bridge rectifiers operation are considered in this article. The instantaneous schemes of six-pulse bridge rectifiers operation in the partial phase mode and also vector diagrams of transformer secondary winding voltages connected by "star-delta" and "star-star" schemes in the full- and open phase modes of three-phase systems of traction power supply are presented. Based on the studies carried out, the relations of the connecting voltages, currents and powers of the considered six-pulse bridge rectifiers in the open phase mode are presented for both controlled and uncontrolled converters.
