 und abwärts bewegen können. Der Stiel   201 trägt eine   bewegliche Spule   22.   Seine Bewegung wird durch eine Dampfung 23 verzögert. Die bewegliche Spule 22 wird von einem Stromtransformator 24 gespeist, welcher in einer Hauptleitung liegt, die Spulen 21 von zwei Spannungstransfonnatoren   25,   welche parallel an der Hauptleitung liegen. Durch chemische   Widerstände   26 wird der Strom in den Spulen 21 verringert. 



   Die Wirkungsweise ist folgende : Es sei angenommen, dass der Synchronmotor unbelastet läuft und dass das bewegliche Kontaktpaar 14 und die übrigen Teile so eingestellt sind, dass der Synchronmotor gerade so stark erregt ist, dass er weder vor-noch nacheilenden Strom abgibt, dass also mit anderen Worten der Leistungsfaktor des Systems gleich   l   ist. Unter diesen Umständen üben die beiden Spannungsspulen 21 auf die bewegliche Spule 23   gleiche Zugkräfte   aus und die letztere beeinflusst daher nicht die Lage der Magnetkerne 20 und des Kontaktpaares   14.   



  Wenn dagegen das Verteilungssystem unausgeglichen wird. so dass der Strom in der beweglichen 
 EMI2.1 
 voreilenden Strom abgibt und dadurch der Phasennacheilung im Verteilungssystem entgegenwirkt und den Leistungsfaktor wieder auf den Wert 7 bringt, vorausgesetzt, dass der Motor 
 EMI2.2 
 im   Verteilungssystem   ist die Wirkung umgekehrt.

 and move downwards. The stem 201 carries a movable coil 22. Its movement is delayed by a damping 23. The movable coil 22 is fed by a current transformer 24 which is located in a main line, the coils 21 from two voltage transformers 25 which are parallel to the main line. The current in the coils 21 is reduced by chemical resistances 26.



   The mode of operation is as follows: It is assumed that the synchronous motor runs unloaded and that the movable contact pair 14 and the other parts are set in such a way that the synchronous motor is just so strongly excited that it emits neither leading nor lagging current, i.e. with In other words, the power factor of the system is equal to 1. Under these circumstances, the two voltage coils 21 exert the same tensile forces on the movable coil 23 and the latter therefore does not affect the position of the magnetic cores 20 and the contact pair 14.



  On the other hand, when the distribution system becomes unbalanced. so that the electricity in the movable
