Description

Wicklungsanordnung für Einankerumformer mit getrennter Drehstrom-und Gleichstromwicklung. Bekanntlich kann man Einankerumformer für Drehstrom und Gleichstrom derart ausführen, daß eine gemeinsame Ankerwicklung Anwendung findet. Hierbei wird, falls das erforderliche Verhältnis zwischen Gleichstromspannung und Drehstromspannung im Umformer nicht von vornherein gegeben ist, die Drehstromnetzspannung mittels eines Transformators angeschlossen.Winding arrangement for single armature converters with separate three-phase and DC winding. It is well known that single-armature converters can be used for three-phase and direct current perform in such a way that a common armature winding is used. Here, if the required ratio between DC voltage and three-phase voltage is not given in the converter from the outset, the three-phase mains voltage by means of connected to a transformer.

Dieser Transformator läßt sich vermeiden, wenn für Gleichstrom und Wechselstrom getrennte Wicklungen auf dem Anker vorgesehenwerdexi, indem die Wechselstromwicklung in gemeinsamen Nuten über die Gleichstromwicklung gelegt wird. Da aber die Wechselstromwicklung meist eine wesentlich höhere Spannung als die Gleichstromwicklung hat, entstehen bei Anordnung beider Wicklungen in gemeinsamen Nuten Isolationsschwierigkeiten. Gute Isolierung der Wicklungen gegeneinander verursacht schlechte Ausfüllung der Nuten und damit eine ungünstige Ausnutzung der Maschine.This transformer can be avoided if for direct current and Alternating current separate windings are provided on the armature by removing the alternating current winding is laid across the DC winding in common slots. But there the alternating current winding usually a much higher voltage than the DC winding If both windings are arranged in common slots, insulation difficulties. Good insulation of the windings from one another causes poor filling of the Grooves and thus an unfavorable utilization of the machine.

Die Erfindung vermeidet diese Nachteile dadurch, daß die beiden Wicklungen in besonderen, getrennten Nuten für jede Wicklung untergebracht werden, indem sowohl für die Gleichstromwicklung wie für die WechseIstromwicklung am Ankerumfang je eine entsprechende Nutenzahl vorgesehen wird. Die Ausführung wird hierbei zweckmäßig derart getroffen, daß Gleichstrom- und Wechselstromnuten nebeneinander und in verschiedener Größe vorgesehen werden, so daß für die Gleichstromwicklung man infolge besserer Ausfüllungsmöglichkeit kleinere Nuten vorsieht wie für Wechselstrom.The invention avoids these disadvantages in that the two windings can be housed in special, separate grooves for each winding by both for the direct current winding as for the alternating current winding on the armature circumference one each corresponding number of slots is provided. The execution is expedient here made such that direct current and alternating current grooves next to each other and in different Size can be provided so that for the direct current winding one as a result of better Filling possibility provides smaller grooves as for alternating current.

Eine beispielsweise Ausführungsform der Erfindung ist in der Zeichnung schematisch dargestellt, indem ein Rotor r am Umfang abwechselnd mit Gleichstromnuten g und Wechselstromnuten w versehen. ist, wobei letztere größer sind als die Gleichstromnuten. Die Erfindung kann selbstverständlich auch derart ausgeführt werden, daß für die Wechselstromwicklung mehr Nuten als für die Gleichstromwicklung vorgesehen sind.An exemplary embodiment of the invention is shown in the drawing shown schematically by placing a rotor r on the circumference alternating with direct current grooves g and alternating current grooves w. is, the latter being larger than the DC grooves. The invention can of course also be carried out in such a way that for the AC winding more slots than are provided for the DC winding.
