Description

Wechselstrom-Gleichstrom-Synchroneinankerumformer mit feststehendem Anker und innerhalb des Ankers kreisendem Feldsystem mit Hilfspolen. Gegenstand der Erfindung ist ein Wechselstrom - Gleichstrom - Synchroneinankerumformer, dessen den Wechselstrom aufnehmender Anker stillsteht, dessen Magnetsystem nebst Hilfspolen umläuft und dessen Kommutator vom Ankerkörper getrennt angeordnet ist und. eine Drehzahl aufweist, die kleiner ist als diejenige des Feldsystems, wobei die Wicklung des Ankers mit den Kommutatorlamellen über eine entsprechende Anzahl von Schleifringen verbunden ist.AC-DC synchronous single armature converter with fixed Armature and within the armature rotating field system with auxiliary poles. object of the invention is an alternating current - direct current synchronous armature converter, whose The armature absorbing the alternating current is stationary, its magnet system and auxiliary poles revolves and the commutator is arranged separately from the armature body and. one Has speed which is smaller than that of the field system, the winding of the armature with the commutator segments via a corresponding number of slip rings connected is.

Die Maschine ist dadurch gekennzeichnet, daß die Anzahl der Feldpole kleiner ist als diejenige der Kommutatorbürstensätze und daß die Drehzahl des Feldsystems multipliziert mit der Polzahl des Feldes gleich ist der Kommutatordrehzahl multipliziert mit der Anzahl der Kommutatorbürstensätze.The machine is characterized in that the number of field poles is smaller than that of the commutator brush sets and that the speed of the field system multiplied by the number of poles in the field is the same as the commutator speed with the number of commutator brush sets.

Dadurch wird die Konstruktion des Umformers auch bei großer Leistung erleichtert, weil der Kommutator von der Maschine getrennt und mit einer viel kleineren Drehzahl betrieben wird. Da die Hauptpole wie auch die Wendepole auf dem schnellaufenden Teile der Maschine angebracht sind, ist keine schlechte Ausnutzung des Eisensystems wegen niedriger Umlaufzahl zu befürchten.This improves the design of the converter even when the power is high facilitated because the commutator is separate from the machine and with a much smaller one Speed is operated. Since the main poles as well as the reversing poles on the high-speed Parts of the machine are attached is not a bad exploitation of the iron system to be feared due to low circulation rate.

Die Zeichnung veranschaulicht zwei Ausführungsbeispiele des Erfindungsgegenstandes. In dem in Abb. i dargestellten Ausführungsbeispiel bezeichnet S den feststehenden Anker eines Dreiphasenumformers, dessen Wicklung 0 mit der Sekundärwicklung des Transformators T verbunden ist. Die Ankerwicklung ist in zwölf Teilwicklungen unterteilt und jede Teilwicklung ist mit einem Ringe des Schleifringkörpers Q und jeder Ring mit einer Lamelle des Kommutators K verbunden.The drawing illustrates two exemplary embodiments of the subject matter of the invention. In In the embodiment shown in Fig. i, S denotes the fixed anchor a three-phase converter whose winding is 0 with the secondary winding of the transformer T is connected. The armature winding is divided into twelve partial windings and each Partial winding is with one ring of slip ring assembly Q and each ring with one Lamella of the commutator K connected.

Die Geschwindigkeit des Kommutators nebst Schleifringkörper ergibt sich, wenn nR die Drehzahl des Feldsystems bezeichnet, nK die Drehzahl des Kommutators, P die Anzahl der Feldpole und B die Anzahl der Bürstensätze aus der Gleichung: nR#P == nK#B.The speed of the commutator and slip ring assembly results from the equation: nR denotes the speed of the field system, nK the speed of the commutator, P the number of field poles and B the number of brush sets: nR # P == nK # B.

Der Erregerstrom für das Umformergleichstromfeld ist von dem Hauptstromkreis abgezweigt.The excitation current for the converter DC field is from the main circuit branched off.

Die in Abb. 2 dargestellte Ausführungsform unterscheidet sich von der vorbeschriebenen dadurch, daB die Einrichtung zur Umformung des Wechselstromes in Gleichstrom mit dem Spannungstransformator des Wechselstromes in der Maschine vereinigt wird. Zu diesem Zwecke befinden sich auf dem Ständer S, nebeneinander und in den gleichen Nuten, zwei voneinander unabhängige Wicklungen W, und W2. Die Wicklung W1, welche die Primärwicklung des Spannungstransformators bildet, ist mit dem Wechselstromnetz verbunden, während die Wicklung W2, die die Sekundärwicklung dieses Transformators darstellt, wie vorher beschrieben, mit den Ringen des Schleifringkörpers Q verbunden ist. Dieser Schleifringkörper ebenso wie der Komrnutator K wird hierbei nicht vom Feldsystem mittels Rädergetriebes mitgenommen, wie dies bei der vorher dargestellten und beschriebenen Ausführungsform der Fall warf sondern durch einen besonderen Synchronmotor L angetrieben, dessen Polzahl gleich ist der Anzahl der Bürstensätze des Kommutators K.The embodiment shown in Fig. 2 differs from the above-described by the fact that the device for converting the alternating current in direct current with the alternating current voltage transformer in the machine is united. For this purpose are located on the stand S, next to each other and in the same slots, two independent windings W, and W2. the Winding W1, which forms the primary winding of the voltage transformer, is with connected to the AC mains, while the winding W2, which is the secondary winding this transformer represents, as previously described, with the rings of the slip ring body Q is connected. This slip ring body as well as the Komrnutator K is here not taken along by the field system by means of a gear train, as was the case with the previous one illustrated and described embodiment threw the case but by one special synchronous motor L driven whose number of poles is equal to the number of Brush sets of commutator K.
