Description
<Desc/Clms Page number 1>
Einrichtung zum Betrieb eines Motorgenerators mit einem als Phasenverbesserer geeigneten Wechselstrommotor.
An Wechselstromnetze angeschlossene Antriebsmotoren von Motorgeneratoren sind oft so ausgeführt, dass sie während des Betriebes zugleich die Phasenverschiebung im Netze verringern oder aufheben können. Zum Beispiel werden Synchronmotoren für Übererregung eingerichtet oder Asynchronmotoren mit Hintermaschinen (Kollektorphasenschiebern od. dgl.) zu Regelsätzen vereinigt.
Erfindungsgemäss wird der Motor in den Betriebspausen vom Generator abgekuppelt und allein als Phasenverbesserer benützt. Zu diesem Zwecke wird im Gegensatz zu den gebräuchlichen Anordnungen, bei denen der Motor stets starr (z. B. durch eine Flanschkapung) mit dem Generator gekuppelt ist,
EMI1.1
kupplung, eingeschaltet. Ist die Kupplung so eingerichtet, dass sie während des Laufes ein-und ausgerückt werden kann, so ergibt sieh der Vorteil, dass der Motor beim Übergang vom Antriebe des Generators auf Leerlauf als Phasenverbesserer und umgekehrt nicht stillgesetzt zu werden braucht, wodurch die Arbeit für den neuerlichen Anlauf erspart wird. Das Einrücken und Ausrücken der Kupplung kann sowohl von Hand aus, als auch durch bekannte Hilfsmittel (z. B. elektromagnetisch) bewirkt werden.
Ebenso kann die Betätigung der Kupplung zwangläufig in Abhängigkeit von dem Betriebszustande einer Arbeitsmaschine gebracht werden, die von dem Stromerzeuger des Motorgenerators gespeist wird (z. B. in Abhängigkeit von der Stellung des Steuer-oder Bremsgerätes).
PATENT-ANSPRÜCHE :
1. Einrichtung zum Betrieb eines Motorgenerators mit einem als Phasenverbesserer geeigneten Wechselstrommotor, gekennzeichnet durch eine betriebsmässig lösbare Kupplung zwischen Generator und Motor, zum Zwecke, in den Betriebspausen den Motor allein als Phasenverbesserer betreiben zu können.

Device for operating a motor generator with an alternating current motor suitable as a phase improver.
Drive motors of motor-generators connected to AC networks are often designed in such a way that they can simultaneously reduce or cancel the phase shift in the network during operation. For example, synchronous motors are set up for overexcitation or asynchronous motors are combined with rear machines (collector phase shifters or the like) to form rule sets.
According to the invention, the motor is disconnected from the generator during breaks in operation and used solely as a phase improver. For this purpose, in contrast to the conventional arrangements in which the motor is always rigidly coupled to the generator (e.g. by a flange cap),
EMI1.1
clutch, switched on. If the clutch is set up so that it can be engaged and disengaged while running, the advantage is that the motor does not need to be shut down as a phase improver and vice versa during the transition from the generator's drive to idling, so that the work for the a new start is saved. The clutch can be engaged and disengaged either by hand or by known aids (e.g. electromagnetic).
Likewise, the actuation of the clutch can inevitably be brought into dependence on the operating state of a work machine that is fed by the power generator of the motor generator (e.g., depending on the position of the control or braking device).
PATENT CLAIMS:
1. Device for operating a motor generator with an alternating current motor suitable as a phase improver, characterized by an operationally releasable coupling between generator and motor, for the purpose of being able to operate the motor alone as a phase improver during breaks in operation.
