Description

Elektrisches Fahrzeug mit Gleichstrommotoren, die von einem aus einem Wechselstromnetz über einen Transformator gespeisten Gleichrichter und von einerBatterie ihren Strom erhalten Es ist bekannt, in mit Wechselstrom betriebenen Bahnnetzen im Verschiebedienst elektrische Fahrzeuge zu verwenden, die mit Gleichstrommotoren ausgerüstet sind, die von einer Batterie gespeist werden, die in .bekannter Weise auf dem Fahrzeug selbst über Gleichrichter vom Wechselstromnetz aufge-Sa_len wird, um hei Fehlen der Wechselstrom-#1>aiinung die Verschiebearbeiten ausführen zu können.Electric vehicle with DC motors powered by one from one AC mains rectifier fed by a transformer and by a battery Getting their electricity It is known to be in alternating current operated railway networks To use electric vehicles in the shifting service, those with DC motors are equipped, which are fed by a battery in .known manner on the vehicle itself via a rectifier from the alternating current network, in order to be able to carry out the shifting work in the absence of the alternating current signal.

ach der Erfindung ist sowohl während ,les Betriebes als auch bei Nullstellung. des Fahrschalters die Batterie parallel zu dem (Teichrichter, der über einen Transformator atn Wechselstromnetz liegt, über Drosselspulen geschaltet, so daß sie bei keiner oder geringer Stromaufnahme der Motoren gelafen wird. Dadurch ist es möglich. jede, auch die kleinste Pause im Betriebe der Lo-I<ocilotive zum Aufladen der mitgeführten Batterie zu verwenden, ohne daß .das Bedieriungspersonal auch nur im .geringsten mit zu-,:itzlicher Arbeit belastet wird. Durch die Drosselspule nach der Erfindung wird erreicht, daß selbsttätig bei geringer Belastung #ler Motoren eine Erhöhung der Gleichspannung am Gleichrichter stattfindet. Sowie die Gleichspaainung am Gleichrichter überwiegt, wird dann .die Batterie geladen.After the invention is both during, les operation and at zero position. of the drive switch, the battery parallel to the (pond rectifier, which has a transformer atn AC mains is connected via inductors, so that they are not at any or low power consumption of the motors. This makes it possible. every, even the smallest break in the operation of the Lo-I <ocilotive to recharge the ones carried along To use battery without .the operating staff even in the slightest is burdened with too -,: additional work. By the choke coil according to the invention it is achieved that automatically with a low load # of engines an increase the DC voltage takes place at the rectifier. As well as the DC pairing on the rectifier predominates, the battery will then be charged.

Die Abbildung zeigt ein Ausführungsbeispiel der Erfindung. Die Primärseite eines Einphasentransformators i eines elektrischen Fahrzeuges liegt über den Stromabnehmer 2 an der Fahrdrahtspannung. Die freien Enden der Sekun:diirseite liegen über Drossehspulen 3 und 4. an den Anoden des Gleichrichters 5, während der ullpunkt :des Transformators an der Saun nielschiene 6 angeschlossen .ist; die zweite Sammelschiene 7 steht mit der Kathode des Gleichrichters 5 ,in Verbindung. An den Sammelschienen 6 und 7 liegen parallel zueinander die Fahrmotoren 8, 9 und die Batterie io.The figure shows an embodiment of the invention. The primary side a single-phase transformer i of an electric vehicle lies across the pantograph 2 at the contact wire voltage. The free ends of the secondary side lie over choke coils 3 and 4. at the anodes of the rectifier 5, while the zero point: of the transformer connected to the sauna rail 6 .is; the second busbar 7 is with the cathode of the rectifier 5, in connection. Are on the busbars 6 and 7 parallel to each other the traction motors 8, 9 and the battery io.
