Description

Reihen-, Reihenparallel-, Parallelschaltung für eine gerade Anzahl von Elektromotoren, insbesondere für Bahnbetriebe. Es sind bereits verschiedene Arten von Reihen-, Reihenparallel-, Parallelschaltungen bekannt. Bei den bisher verwendeten Schaltungen dieser Art, die ohne Leistungsunterbrechung umzuschalten gestatten, wurde in den meisten Fällen eine der Anzahl der Motoren entsprechende Anzahl von Widerstandssätzen zum Anlassen der Motoren vorgesehen, wodurch umständliche Schaltungsaufgaben entstanden. Wurde hingegen nur ein Widerstandssatz verwendet, so wurde dieser ungleichmäßigen Belastungen ausgesetzt. Diese beiden Anordnungen ergaben daher Schwierigkeiten, die mit den zu Gebote stehenden Mitteln nur schwer beseitigt werden konnten. Nach der Erfindung erfolgt das Anlassen einer geraden Anzahl von Motoren in Reihen-, Reihenparallel-, Parallelschaltung mit einem einzigen Widerstandssatze, der während des gesamten Anlaßvorganges in allen Teilen vollkommen gleichmäßig belastet ist. Dieses wird dadurch erreicht, daß der Widerstandssatz eine der Anzahl der Motoren entsprechende Anzahl 211 von Anzapfungen besitzt, von denen die eine zweckmäßig an dem einen Ende des Widerstandssatzes liegt. Die in der Mitte des Widerstandssatzes liegenden Anzapfungen 211-i können über je einen Schalter an je einen Verbindungspunkt zweier während des Anlassens und während des Betriebes dauernd miteinander verbundenen Motorklemmen und die letzte am Ende liegende Anzapfung mit dem einen freien Ende der hl der genannten Weise miteinander fest verbundenen Motoren angelegt werden. Die Schaltungsweise des Widerstandssatzes ergibt hierbei gleichsam ein Spiegelbild der Schaltweise der :Motoren als Ganzes betrachtet. Die Stromrichtung wird in den Widerstandsteilen in gleicher Art umgekehrt wie in den einzelnen Motoren. Um ohne Leistungsunterbrechung zu .schalten, wird bei den Übergängen von einer zur anderen Motorgruppierung immer nur eine Motorgruppe bzw. einzelne der Motoren über einen Teil des Anlaßwiderstandes hinweg einen Augenblick lang kurzgeschlossen.Series, series-parallel, parallel connection for an even number of electric motors, especially for railway companies. They are already different Types of series, series-parallel, parallel connections are known. With the so far used circuits of this type that switch without interrupting the power allowed, in most cases one of the number of motors was used Number of resistor sets provided for starting the engines, making it cumbersome Circuit tasks arose. If, on the other hand, only one set of resistors was used, so it was exposed to uneven loads. These two arrangements therefore resulted in difficulties that were difficult with the means available could be eliminated. According to the invention, the tempering takes place in a straight line Number of motors in series, series-parallel, parallel connection with a single one Resistance sets that are perfect in all parts during the entire starting process is evenly loaded. This is achieved in that the resistor set has a number 211 of taps corresponding to the number of motors, of one of which is conveniently located at one end of the set of resistors. In the taps 211-i lying in the middle of the set of resistors can each have one Switch to one connection point of two during starting and during Operation continuously interconnected motor terminals and the last tap at the end with one free end of the mentioned Motors that are permanently connected to each other can be created. The way of switching of the set of resistance results in a mirror image of the switching mode of the : Engines viewed as a whole. The current direction is in the resistor parts reversed in the same way as in the individual motors. To without interruption of service to .switch is always at the transitions from one motor grouping to the other only one motor group or individual motors over part of the starting resistor short-circuited away for a moment.

Die Abb. i der Zeichnung zeigt schematisch die Schaltung, während die Abb.2 angibt, welche Schalter in den einzelnen Stellungen geschlossen sind. Die wagerechte Zahlenreihe über der Tabelle bedeutet die Bezeichnungen. der Schalter, während die senkrechte Zahlenreihe links neben der Tabelle die Schaltstellungen angibt. Es bedeutet in der Abb. 1: 15 die Stromzuleitung, 16 und 1 7 zwei Hauptschalter, 1, 2, 3 ... 8 vor dem Anlaßwiderstand liegende Schalter, 9, 11, 12 und 13 hinter den vier Anzapfungen liegende Schalter, io und 14 zwei Schalter, die die Verbindung mit der Erde herstellen, und 18, i9, 20 und 21 die vier Motoren.Fig. I of the drawing shows a schematic of the circuit, while Fig. 2 shows which switches are closed in the individual positions. The horizontal row of numbers above the table means the designations. the switch, while the vertical row of numbers to the left of the table indicates the switch positions. In Fig. 1: 15 it means the power supply, 16 and 1 7 two main switches, 1, 2, 3 ... 8 switches located in front of the starting resistor, 9, 11, 12 and 13 switches located behind the four taps, io and 14 two switches that make the connection to earth, and 18, i9, 20 and 21 the four motors.

In der ersten Stellung sind die Schütze 16 und 9 geschlossen. Der Strom fließt :hier von der Zuleitung 15 über den Schalter 16, durch den gesamten Widerstand, den Schalter 9, die vier in Reihe liegenden Motoren 18, 19, 20 und 21 an Erde. In der Stellung 2 wird ein Teil des Anlaßwiderstandes durch den Schalter 4 kurzgeschlossen. In der Stellung 3 liegen die Motoren in Reihenschaltung an voller Spannung über die Schalter 16, 8 und 9; der noch eingerückte Schalter .1 wird in der nächsten Stellung 3a unterbrochen und dafür der Schalter 12 eingelegt. In dieser Zwischenstellung 3a fließt ein Strom über den Schalter 16, die obere Hälfte des Widerstandes, den Schalter 12 und die beiden Motoren 2o und 21 an Erde. Ein zweiter Strom wird über die Schalter 17, 8 und 9 zu den Motoren 18, i9 usw. geleitet. In der darauffolgenden Zwischenstellung 31' wird der Schalter 9 unterbrochen und die beiden Motoren 18 und i 9 sind über den unteren Teil des Widerstandes einen Augenblick lang kurzgeschlossen. In der Stellung q. wird der Schalter io geschlossen, so daß die beiden Motorgruppen 18, i 9 und 2o, 21 über den gesamten Widerstand durch den Schalter 12 gespeist werden. Hierauf wird in, der Stellung 5 ein Teil des Widerstandes durch die Schalter 2 und 6 abgeschaltet. Diese beiden Schalter unterbrechen aber wiederum in der Stellung 6, in der der Schalter q. :eingelegt wird, so daß in dieser Stellung die Reihenparallelstellung der vier Motoren erreicht wird.In the first position the contactors 16 and 9 are closed. Of the Current flows: here from the lead 15 via the switch 16, through the entire Resistance, the switch 9, the four motors 18, 19, 20 and 21 in series on earth. In position 2, part of the starting resistance is through the switch 4 shorted. In position 3, the motors are connected in series to full Voltage across switches 16, 8 and 9; the switch .1, which is still engaged, changes to the next position 3a is interrupted and the switch 12 is inserted. In this Intermediate position 3a, a current flows through the switch 16, the upper half of the Resistance, the switch 12 and the two motors 2o and 21 to earth. A second Power is fed to motors 18, i9, etc. via switches 17, 8 and 9. In the subsequent intermediate position 31 ', the switch 9 is interrupted and the both motors 18 and i 9 are about the lower part of the resistor for a moment long shorted. In the position q. the switch io is closed, so that the two motor groups 18, i 9 and 2o, 21 over the entire resistance through the Switch 12 are fed. Then, in position 5, part of the resistance switched off by switches 2 and 6. However, these two switches interrupt again in position 6, in which the switch q. : is inserted so that in this Position the series parallel position of the four motors is achieved.

Die weitere Schaltung, d. h. der Obergang von der Reihenparallel- zur Parallelschaltung, vollzieht sich in den. einzelnen Motorgruppen 18, i9 und 20, 21 in gleicher Weise wie zu Anfang bei Übergang von der Reihen- zur Reih enparallelstellung aller vier Motoren. In der Zwischenstellung 61' werden hierbei wiederum zwei der Motoren für kurze Zeit über einen Teil des Anlaßwiderstandes hinweg kurzgeschlossen, während die zwei anderen Motoren an Spannung liegen, so daß auch hier ohne Unterbrechung der Leistung geschaltet wird.The further circuit, d. H. the transition from the row parallel for parallel connection takes place in the. individual engine groups 18, i9 and 20, 21 in the same way as at the beginning with the transition from the row to the row parallel position of all four engines. In the intermediate position 61 ', two of the Motors short-circuited over part of the starting resistance for a short time, while the two other motors are connected to voltage, so that here too without interruption the power is switched.
