Abstract:
The present invention relates to an energy management and distribution system for a railbound vehicle (1 ), comprising: - a plurality of power electronic traction transformers (5) for coupling to an AC catenary (3) for receiving high-voltage AC power; - a common DC bus (6) being connected for supplying electrical energy to one or more loads (8); and - a control unit (9) capable of activating and deactivating the power electronic traction transformers (5) depending on the total power required by the loads (8).
Abstract:
The present invention relates to an end ring element (10) for forming an end ring (5) for a coil device (1), wherein the end ring element (10) is formed by a plane band which extends along a longitudinal direction (L) and a width direction (W), wherein the band provides a constant spacing capability over its length along the longitudinal direction (L); and a higher stiffness in the width direction (W) than in the longitudinal direction (L).
Abstract:
The invention relates to a traction transformer for railbound vehicles comprising: an insulating liquid filled enclosure, at least two windings contained in the enclosure, a transformer core, mounting means for mounting the transformer to the railbound vehicle, wherein the transformer core is arranged outside the enclosure, and wherein the mounting means are attached to the transformer core.
