sind mit Kontakten 13, 14 versehene Hebel 15, 16 verbunden, welche drehbar gelagert und übereinander angeordnet sind. Die beiden Kontakte 13, 14 bilden die Enden eines Stromkreises, welcher die eine Wicklung 24 eines Differentialrelais 22 einschliesst. Die beiden Wicklungen 23

Widerstand 27 eingeschaltet.
Die Wirkungsweise der beschriebenen Einrichtung ist folgende : Ist der Regelungswiderstand 27 kurzgeschlossen, so steigt mit der Spannung des Erregers auch die des Wechselstromerzeugers, so dass die beiden Solenoide 17, 19 stärker erregt werden und in der vorher beschriebenen Weise den Stromkreis der Spule 24 schliessen ; dadurch wird der Widerstand 27 eingeschaltet.
Entsprechend der Erhöhung des Widerstandes in der Feldwicklung der Zusatzmaschine vormindert sich einerseits die Spannung in dem Erregerstromkreise 7, 8 und die des Wechselstromerzeugers, andererseits die Anziehungskraft der Solenoide 17, 19. Die Kontakte 13, 14 trennen sich, während der Kontakt 26 durch die Spule 23 geschlossen wird und den Widerstand 27 kurzschliesst. Es ist hienach klar, dass durch geeignete Abmessungen des Widerstandes 27 erreicht werden kann, dass die elektromotorische Kraft der Zusatzmaschine derart verändert wird, dass die Spannung der Wechselstromerzeuger 2 bzw. 3 bei Belastungsschwankungen konstant bleibt, ohne dass die Erregung der Erregermaschine verändert werden braucht.

levers 15, 16 provided with contacts 13, 14 are connected, which are rotatably mounted and arranged one above the other. The two contacts 13, 14 form the ends of a circuit which includes one winding 24 of a differential relay 22. The two windings 23

Resistor 27 switched on.
The mode of operation of the device described is as follows: If the control resistor 27 is short-circuited, the voltage of the exciter also increases with the voltage of the alternator, so that the two solenoids 17, 19 are more strongly excited and close the circuit of the coil 24 in the manner described above; this turns on the resistor 27.
Corresponding to the increase in the resistance in the field winding of the auxiliary machine, on the one hand the voltage in the excitation circuits 7, 8 and that of the alternator, on the other hand the attraction of the solenoids 17, 19, the contacts 13, 14 separate, while the contact 26 through the coil 23 is closed and the resistor 27 short-circuits. It is then clear that by suitable dimensions of the resistor 27 it can be achieved that the electromotive force of the additional machine is changed in such a way that the voltage of the alternator 2 or 3 remains constant with load fluctuations without the excitation of the exciter machine needing to be changed.
