Description
Anordnung zum Betrieb von Induktionsmaschinen mit nur elektrisch gekuppelter Kollektorhintermaschine. Für den Betrieb von Induktionsmaschinen mit nur elektrisch gekuppelter Kollektorhintermaschine ist bereits eine Anordnung bekannt, bei der die Kollektorhintermaschine von einer mit dem Netz gekuppelten Synchronmaschine angetrieben wird Die Kollektorhintermaschine wird im Läufer über Schleifringe erregt, und zwar von einer mit der Hauptmaschine gekuppelten Synchronmaschine, deren Ständerwicklung an die Schleifringe der Hintermaschine angeschlossen ist, während die Läuferwicklung mit Gleichstrom erregt wird. Es ist also dafür eine besondere Gleichstromquelle erforderlich. Die Erfindung betrifft nun eine Verbesserung einer derartigen Anordnung, die sich insbesondere dann als zweckmäßig erweist, wenn die obengenannte Gleichstromquelle für die Erregung der Synchronmaschine nicht schon vorhanden ist. Erfindungsgemäß wird für den Antrieb der Kollektorhintermaschine eine als Einankerumformer ausgebildete Synchronmaschine vorgesehen, wobei der Gleichstromkollektor gleichzeitig die Erregung der mit der Hauptmaschine gekuppelten Synchronmaschine speist. Insbesondere wird man zweckmäßigerweise eine Synchronmaschine asynchroner Bauart mit Gleichstromkollektor für die Selbsterregung benutzen. Der Gleichstromkollektor dieser Synchronmaschine speist also außer seiner eigenen Erregung noch die Erregung der mit der Hauptmaschine in der Drehzahl gekuppelter Erregermaschine. i Die Zeichnung zeigt die neue Anordnung an einem Beispiel. i ist der asynchrone Hauptmotor, 2 die Kollektorhintermaschine für die i Phasenkompensierung bzw. für die Regelung der Drehzahl des Hauptmotors. Die Kollek torhintermaschine ist mit dem Hauptmotor nur elektrisch gekuppelt, sie wird von der synchron ; arbeitenden Asynchronmaschine 1 ¢ angetrieben. Die Maschine 14 wird auf ihrer Läuferseite über Schleifringe vom Transformator i i aus gespeist. Sie besitzt einen Gleichstromkollektor, dessen um i8o° einander gegenüberstehende Bürsten für den synchronen Betrieb die dreiphasige Ständerwicklung in der gezeichneten Schaltung mit Gleichstrom erregen- Die Ständerwicklung steht außerdem mit dem Anlasser 15 in Verbindung. Die auf der Welle des Hauptmotors sitzende Wechselstromerregennaschine 9 wird .ebenfalls vom Gleichstromkollektor der Maschine 14 erregt, und die Sekundärwicklung der Wechselstromerregermaschine 9 erregt wieder die Kollektorhintermaschine 2.Arrangement for the operation of induction machines with only electrically coupled Collector rear machine. For the operation of induction machines with only electric coupled collector rear machine is already known an arrangement in which the collector rear machine from a synchronous machine coupled to the network is driven The collector rear machine is excited in the rotor via slip rings, namely from a synchronous machine coupled to the main machine, its stator winding is connected to the slip rings of the rear machine, while the rotor winding is excited with direct current. So it is a special DC source for this necessary. The invention now relates to an improvement in a Such an arrangement, which proves particularly useful when the The above-mentioned direct current source for the excitation of the synchronous machine does not already exist is available. According to the invention for driving the collector rear machine a synchronous machine designed as a single armature converter is provided, the direct current collector at the same time the excitation of the synchronous machine coupled with the main machine feeds. In particular, it is expedient to make a synchronous machine more asynchronous Use type with DC collector for self-excitation. The DC collector this synchronous machine also feeds the excitation in addition to its own excitation the speed of the exciter coupled to the main machine. i The drawing shows the new arrangement using an example. i is the main asynchronous motor, 2 die Collector rear machine for the i phase compensation or for the regulation of the Main motor speed. The collector rear machine is with the main engine only electrically coupled, it is synchronized by the; working asynchronous machine 1 ¢ powered. The machine 14 is on its rotor side via slip rings from Transformer i i powered off. It has a direct current collector, its around i8o ° opposing brushes for synchronous operation the three-phase Excite the stator winding in the circuit shown with direct current - The stator winding is also in communication with the starter 15. The one on the shaft of the main engine seated AC rain machine 9 is. Also from the DC collector of the machine 14 energized, and the secondary winding of the alternating current exciter 9 again excites the collector rear machine 2.
Die Wirkungsweise der geschilderten Anordnung ist im übrigen dieselbe wie bei der Verwendung einer asynchron arbeitenden Drehstromnebenschlußmaschine. Mittels des regelbaren Transformators i i kann daher ebenfalls die Größe der Gleichspannung am Kollektor der Maschine 14 und damit die Größe der von der Maschine 9 gelieferten Wechselspannung beeinflußt werden.The mode of operation of the arrangement described is otherwise the same as when using an asynchronous three-phase shunt machine. The size of the direct voltage can therefore also be determined by means of the controllable transformer i i at the collector of the machine 14 and thus the size of the one supplied by the machine 9 AC voltage can be influenced.
