Description
Schaltanordnung zur Vermeidung einer elektrodynamischen Bremsung des geführten Triebwagens von zwei in Zugsteuerung fahrenden Triebwagen Werden zwei zweimotorige, durch Fahrschalter gesteuerte ,Triebwagen zu -einem Zuge zusammengekuppelt betrieben, wie dies beispielsweise bei Straßen- und *Schnellbahnen häufig der Fall ist, so können in bekannter Weise die Motoren eines jeden Triebwagens für gemeinsame Fahrt dauernd einander parallel geschaltet und die so gebildeten Motorgruppen serienparallel durch den Fahrschalter des Führerwagens gesteuert werden. Diese Schaltung hat den Vorteil, daß die Anzahl der Starkstrom führenden Anschlußleitungen zwischen den beidenTriebwagen niedrig gehalten werden kann. Ein Nachteil dieser Schaltung ist jedoch, daß bei der Rückwärtsfahrt die Motoren des geführten Triebwagens vom Führerwagen aus nicht umgesteuert werden können; sie erregen sich daher selbst und bremsen dadurch den Zug. Um diese Selbsterregung zu vermeiden und ein Rückwärtsfahren des Zuges zu ermöglichen, werden nach der Erfindung bei Rückwärtsfahrt die Felder des geführten Triebwagens durch den Fahrschalter des führenden Triebwagens kurzgeschlossen. Der Antrieb des Zuges erfolgt hierbei lediglich durch die Motoren des Führertriebwagens.Switching arrangement to avoid electrodynamic braking of the guided railcar of two railcars driving in train control Become two two-motor, motorized railcars controlled by a driving switch coupled together to form a train operated, as is often the case, for example, with trams and high-speed railways is, so can the engines of each railcar for common in a known manner Drive continuously connected in parallel with each other and the motor groups formed in this way in series can be controlled by the driving switch of the driver's car. This circuit has the Advantage that the number of power lines leading between the both railcars can be kept low. One disadvantage of this circuit is however, that when reversing, the motors of the railcar from the driver's car cannot be redirected from; therefore they excite themselves and thereby slow down the Train. To avoid this self-excitement and to reverse the train to enable the fields of the guided according to the invention when reversing Railcar short-circuited by the drive switch of the leading railcar. Of the The train is only driven by the engines of the driver's car.
In den Abbildungen sind Ausführungsbeispiele der Erfindung schematisch für zweimotorige Triebwagen dargestellt.Exemplary embodiments of the invention are shown schematically in the figures shown for twin-engine railcars.
Abb. z zeigt die hierbei verwendete, an. sich bekannte Schaltung. Der Anker r und die Feldwicklung 2 eines Motors sind dem Anker 3 und der Feldwicklung q. des zweiten Motors in dem Ausführungsbeispiel in umgekehrter Reihenfolge parallel geschaltet. Der Strom wird dann für die Fahrt durch die zwei Leitungen 13 und 16 an den Punkten A und B den einander parallel geschalteten Motoren zugeführt, die mit der im Führertriebwagen in gleicher Weise geschalteten Gruppe in Reihen- bzw. ParallelschaltunK angelassen werden. Zum Bremsen dienen die mit C und D verbundenen Leitungen 1q. und 15, wobei die in Kreuzschaltung befindlichen Motoren des Beiwagens mit den ebenfalls über Kreuz geschalteten Motoren des Führertriebwagens etwa unter Benutzung der Leitung 13 als Ausgleichsleitung verbunden werden.Fig. Z shows the one used here. known circuit. The armature r and the field winding 2 of a motor are the armature 3 and the field winding q. of the second motor in the exemplary embodiment connected in parallel in reverse order. The current is then fed through the two lines 13 and 16 at points A and B to the motors connected in parallel, which are started in series or parallel with the group connected in the same way in the driver's railcar. The lines 1q connected to C and D are used for braking. and 15, the motors of the sidecar, which are in cross-connection, being connected to the motors of the driver's railcar, which are also cross-connected, for example using line 13 as a compensating line.
Abb.2 zeigt die Schaltung der Motoren des geführten Triebwagens. Durch den Fahrschalter 5o können die Feldwicklung :2 des Fahrmotors z und die Feldwicklung q. des Fahrmotors 3 kurzgeschlässen werden.Fig. 2 shows the circuit of the motors of the guided railcar. By the travel switch 5o can be the field winding: 2 of the travel motor z and the field winding q. of the travel motor 3 are short-circuited.
Bei Rückwärtsfahrt des Zuges werden zur Verhinderung der Selbsterregung die Feldwicklungen durch den Fahrschalter des Führertriebwagens. kurzgeschlossen, beispielsweise durch Verbinden der Leitungspaare 13 und 1q. bzw. 15 und r6: Es können auch die Motoranker selbst kurzgeschlossen werden, z. B. durch Verbindung der Leitungen 13 und 15 bzw. 1q. und 16, da dann der Ankerstrom nicht mehr durch die Erregerwicklung fließt, sondern über diese Verbindung und infolgedessen lediglich der geringe remanente Magnetismus vorhanden ist. Die Motoren des geführten Triebwagens laufen infolgedessen bei Rückwärtsfahrt leer. Der Antrieb des Zuges erfolgt dann nur durch die Motoren des Führertriebwagens.When the train is reversing, the field windings are switched off by the driving switch of the driver's car to prevent self-excitation. short-circuited, for example by connecting the line pairs 13 and 1q. or 15 and r6: The motor armature itself can also be short-circuited, e.g. B. by connecting lines 13 and 15 or 1q. and 16, since then the armature current no longer flows through the excitation winding, but only the low remanent magnetism is present via this connection and as a result. As a result, the motors of the railcar run idle when reversing. The train is then driven only by the engines of the driver's railcar.
