Es ist bekannt, die auf den einzelnen WagenIt is known to work on the individual wagons
eines Zuges angeordneten Elektromotoren von dem Führerwagen aus zu regeln, der. mit einer alle Elektromotoren speisenden Dynamomaschine ausgerüstet ist.of a train arranged by electric motors to regulate the driver's car, the. with a dynamo that feeds all electric motors is equipped.
Die Erfindung besteht darin, daß die Anker der -Elektromotoren und deren Magnetwicklungen getrennt voneinander aus durchgehenden Leitungen gespeist werden und die Schal tung der Elektromotoren für Vorwärtsgang, Rückwärtsgang und Bremsung durch auf dem Führerwagen vereinigte Apparate, z. B. einen einzigen Umschalter, bewirkt wird. Ferner ist gemäß der Erfindung die Gruppe der Anker mit der der Magnet wicklungen für Vorwärts- und Rückwärtsgang in Reihe geschaltet.The invention consists in that the armature of the electric motors and their magnetic windings are fed separately from one another from continuous lines and the circuit the electric motors for forward gear, reverse gear and braking by devices combined on the driver's car, e.g. B. a single toggle switch, is effected. Furthermore, according to the invention, the group is the anchor connected in series with the magnet windings for forward and reverse gear.
In beiliegender Zeichnung ist eine Ausführungsform der Schaltung beispielsweise dargestellt. D ist der Anker einer fremd erregten Dynamomaschine, deren Spannung also beliebig geändert werden kann, α sind die Anker und b die Feldwicklungen der Fahrzeugelektromotoren. U ist ein zweipoliger, auf dem Führerwagen angeordneter Umschalter, der in Stellung I Vorwärtsfahrt, in Stellung II Bremsung und in Stellung III Rückwärtsfahrt ergibt. In Stellung I geht der Strom von dem + Pol der Dynamo in die Leitung i, verzweigt sich auf sämtliche ^Anker der Elektro-In the accompanying drawing, an embodiment of the circuit is shown as an example. D is the armature of an externally excited dynamo, the voltage of which can therefore be changed at will, α are the armature and b are the field windings of the vehicle's electric motors. U is a two-pole switch located on the driver's car, which results in forward travel in position I, braking in position II and reverse travel in position III. In position I the current goes from the + pole of the dynamo into line i, branches off to all ^ armatures of the electric
motoren und kommt in der Leitung 2 wieder zusammen, geht sodann durch den Umschaltermotors and comes back together in line 2, then goes through the switch
. in die Leitung 3, verzweigt sich hier auf die Feldmagnetwicklungen und wird durch die Leitung 4 zum —.Pol der Dynamo zurückgeleitet. In Stellung III ändern sich die Verbindungen nur insofern, als der Strom die Anker β in Richtung von 2 nach 1 durchfließt. Die Kontaktplatten E sind an den- Schalthebeln isoliert befestigt.. into line 3, branches off here to the field magnet windings and is returned through line 4 to the —.Pol of the dynamo. In position III the connections change only insofar as the current flows through the armature β in the direction from 2 to 1. The contact plates E are attached to the switching levers in an insulated manner.
Die selbsttätige Regelung der Fahrgeschwindigkeit nach der Größe des Bewegungswiderstandes des Zuges tritt dadurch ein, daß die Anker der Elektromotoren mit den Feldwicklungen wie bei Hauptstrommotoren in Reihe geschaltet sind. Bei zunehmendem Bewegungswiderstände erhöht sich die Ankerstromstärke und damit auch die Erregerstromstärke in den einzelnen Feldmagnetwicklungen.The automatic control of the driving speed according to the size of the resistance to movement the train occurs in that the armature of the electric motors with the field windings as with main current motors are connected in series. With increasing resistance to movement the armature current strength increases and thus also the excitation current strength in the individual field magnet windings.
In Stellung II des Umschalters U sind die Elektromotoren auf Bremsung geschaltet. Die Ankerleitungen 1 und 2 sind mit dem Bremswiderstand B verbunden, und der Strom der Dynamo wird durch die an den Schalthebeln isoliert befestigten Überbrückungskontakte E unmittelbar in die. Magnetwicklungen geleitet. Die Bremswirkung tritt ein, sobald die Dynamomaschine D erregt wird. Niedrige Werte der Dynamospannung genügen bereits zu ausreichender Erregung der Elektromotorenfelder. Um dadurch die Feinheit der Bremsregulierung nicht zu beeinträchtigen, kann in die Leitung zwischen der Dynamomaschine und dem Überbrückungskontakt ein Vorschaltwiderstand von zweckmäßiger Größe gelegt werden. Da die Erregerstromstärke aller Elekiromotoren. bei der angegebenen SchaltungIn position II of switch U , the electric motors are switched to braking. The armature lines 1 and 2 are connected to the braking resistor B , and the current of the dynamo is directly fed into the by the bridging contacts E , which are insulated on the shift levers. Magnet windings conducted. The braking effect occurs as soon as the dynamo D is excited. Low values of the dynamo voltage are already sufficient to excite the electric motor fields. In order not to impair the fineness of the brake regulation, a series resistor of suitable size can be placed in the line between the dynamo and the bridging contact. Since the excitation current of all electric motors. with the specified circuit
(2. Auflage, ausgegeben am S. Januar igiz.)(2nd edition, issued on January 5th igiz.)
überall gleich-ist, so hängt die Bremswirkung der einzelnen Elektromotoren von deren Umdrehungszahl ab. Zur Erzielung gleicher Belastung aller Anker beim Bremsen wie beim Fahren kommt es also darauf an, daß sie stets möglichst gleiche Umdrehungszahlen haben.is the same everywhere, the braking effect depends of the individual electric motors on their number of revolutions. To achieve the same load of all anchors when braking as when driving it is important that they always have the same number of revolutions as possible.
Um die-Überlastungen einzelner Anker auszugleichen, kann man sich eines Parallelwider-Standes zu den Magnetwicklungen- der Elektromotoren bedienen, der zweckmäßig aus einem Material mit möglichst hohem Temperatürkoeffizienten hergestellt wird. Dieser Parallelwiderstand ist so zu bemessen, daß er einen Teil des dem. einzelnen Elektromotor zugeführten Erregerstromes nicht durch die Erregerwicklung gehen läßt, sondern vorbeileitet. Wird dieser Parallel widerstand indem Gehäuse des Elektromotors an einer Stelle befestigt, bei der sich Erwärmungen des Ankers' zuerst bemerkbar machen (also in der Regel in der Nähe des Kollektors), so wird mit zunehmender Änkerbelastung seine Temperatur und damit sein Widerstand erhöht. Der vorbeigeleitete Strom wird geschwächt und der Erregerstrom entsprechend erhöht. Die dadurch eintretende Steigerung der elektromotorischen Gegenkraft des Ankers hat. die gewünschte Reduktion der Ankerstromstarke zur Folge.In order to compensate for the overloading of individual anchors, a parallel resistance can be used to use the magnetic windings of the electric motors, which expediently a material with the highest possible temperature coefficient is produced. This parallel resistance is to be measured in such a way that it is part of the dem. single electric motor supplied excitation current does not go through the excitation winding, but bypasses it. Will this parallel resistance by adding Housing of the electric motor fastened at a point where the armature heats up first become noticeable (i.e. usually in the vicinity of the collector), it increases with increasing Ankerbelastung increases its temperature and thus its resistance. The one escorted by Current is weakened and the excitation current is increased accordingly. The thereby occurring increase in the counter electromotive force of the armature. the desired Reduction of the armature current strength as a result.
