Description

Schaltung für Wechselstrompufferanlagen, bestehend aus einem kompensierten Schwungradhauptmotor- mit elektrisch betriebenen Hilfsantrieben Bei Antrieben, die von Schwungradumformern gespeist werden, bedeutet es einen großen wirtschaftlichen Vorteil, einen einmal begonnenen Arbeitsgang, z. B. einen Förderzug, auch dann beendigen zu können, wenn die den Umformer speisende Netzspannung ausbleibt. Bei bekannten Anordnungen kann man zwar den Umformer selbst dadurch in Gang halten, daß man die in den Schwungmassen aufgespeicherte Energie ausnutzt. Zur Fortsetzung des Betriebes ist es jedoch notwendig, daß auch die zu dem Antrieb gehörigen Hilfsmaschinen, ohne die der Betrieb nicht weitergeführt werden kann, z. B. Ölpumpen, Ventilatoren, Erregerumformer u..dgl., weiterlaufen.Circuit for AC buffer systems, consisting of a compensated Flywheel main motor with electrically operated auxiliary drives For drives that fed by flywheel converters, it means a great economic Advantage of an operation once started, e.g. B. terminate a conveyor train to be able to if the mains voltage supplying the converter fails. At acquaintances Arrangements can indeed keep the converter going by that one utilizes the energy stored in the flywheels. To continue operations However, it is necessary that the auxiliary machines belonging to the drive, without which the operation cannot continue, e.g. B. Oil pumps, fans, excitation converters and the like, continue to run.

Die Erfindung ermöglicht eine solche Fortführung des gesamten Betriebes in Pufferanlagen bei Ausbleiben der Netzspannung. Erfindungsgemäß wird der Hauptmotor kompensiert ausgeführt und werden Hilfsantriebe nicht an die Sammelschiene, sondern unmittelbar an dessen Klemmen, wenigstens aber zwischen diese und den ersten selbsttätigen Schalter angeschlossen. Bleibt bei einer solchen Anordnung .die Netzspannung aus, so hält der kompensierte Motor, da er der Zuführung von Blindleistung aus dem Netz nicht bedarf, die Spannung aufrecht. Er wird also zum Generator, der seine Antriebsenergie den Schwungmassen entnimmt und damit die Hilfsantriebe speist. Eine Schaltung nach der Erfindung zeigt die Abbildung.The invention enables such a continuation of the entire operation in buffer systems when there is no mains voltage. According to the invention, the main engine Executed compensated and auxiliary drives are not connected to the busbar, but directly at its terminals, but at least between these and the first automatic ones Switch connected. If there is no mains voltage with such an arrangement, so the compensated motor stops, since it is supplying reactive power from the network does not need to maintain the tension. So it becomes a generator that provides its drive energy takes from the centrifugal masses and thus feeds the auxiliary drives. A circuit after of the invention is shown in the figure.

i sei die Sammelschiene der Zentrale, die mit der Sammelschiene 2 des Umformerwerkes durch die Verbindungsleitung 3 verbunden ist. 4 ist dexAntriebsmotor d-es Schwungrad-Umformers, der durch die Kollektorhintermaschine 5 kompensiert ist. 6 ist das Schwungrad, 7 und 8 sind die Gleichstromdynamos des Umformers. Die Hilfssammelschiene 9 ist erfindungsgemäß unmittelbar an die Klemmen des Motors 4 angeschlossen und speist die Hilfsantriebe io, ii und 12, die für Erregung, für Ölzuführung u. dgl. vorgesehen sind. Sind nun die Schalter 13, 14 oder 15 mit selbsttätigen Auslösevorrichtungen versehen, so werden sie, bei Ausbleiben oder Sinken der Netzspannung, beispielsweise bei Kurzschluß auf der Leitung 3, abgeschaltet. Der Schwungradumformer läuft jedoch weiter und gibt einerseits mechanische Energie an die Gleichstromdynamos 7 und 8, andererseits mit der als Generator laufenden Maschine 4 elektrische Energie an die Sammelschiene 9 zur Speisung der Hilfsantriebe io, ii und 12 ab. Die Erfindung erstreckt sich auf alle Anordnungen mit Asynchronmaschinen, die mit beliebigen Mitteln kompensiert sind.i is the busbar of the control center that connects to busbar 2 of the converter is connected by the connecting line 3. 4 is a dex drive motor d-es flywheel converter, which is compensated by the commutator rear machine 5. 6 is the flywheel, 7 and 8 are the DC dynamos of the converter. The auxiliary busbar 9 is directly connected to the terminals of the motor 4 and according to the invention feeds the auxiliary drives io, ii and 12, which are used for excitation, for oil supply and the like. are provided. Are now the switches 13, 14 or 15 with automatic release devices provided, they are, for example, if the mains voltage fails or drops in the event of a short circuit on line 3, switched off. However, the flywheel converter is running further and on the one hand gives mechanical energy to the DC dynamos 7 and 8, on the other hand, with the machine 4 running as a generator, electrical energy to the Busbar 9 for feeding the auxiliary drives io, ii and 12. The invention extends on all arrangements with asynchronous machines, which compensated by any means are.
