 besonders hohem Grade dazu, nach einem Überregulieren durch die gegenseitige Beeinflussung der Phasen untereinander erst nach langem Hin-und Herregulieren zur Ruhe zu kommen Wenn z. B. bei einem aus einem Dreiphasennetz gespeisten Karbidofen, ähnlich wie in dem in der Zeichnung für eine Elektrode dargestellt, die drei Elektroden entsprechend den Strömen in den drei Zuleitungen eingestellt werden sollen, wird die Anordnung nach der Erfindung so getroffen, dass jede Elektrode für sich bewegt werden kann, dass aber für die drei Reguliervorrichtungen ein gemeinsamer Unterbrecher vorgesehen ist mit drei gekuppelten Kontaktscheiben, deren Kontaktsegmente um 120'gegeneinander versetzt sind, so dass die Regelung absatzweise und in den drei Phasen der Reihe anch   abwechselnd   erfolgt.

   



   PATENT-ANSPRÜCHE :
1. Anordnung zur Vermeidung des   Uberregelns   bei selbsttätigen Regelvorrichtungen, bei denen die Regelung absatzweise erfolgt, dadurch gekennzeichnet, dass durch eine besondere, von der eigentlichen 
 EMI2.1

 to a particularly high degree to come to rest after overregulating through the mutual influencing of the phases with each other only after long back and forth regulation. B. in a carbide furnace fed from a three-phase network, similar to that shown in the drawing for an electrode, the three electrodes are to be set according to the currents in the three leads, the arrangement according to the invention is made so that each electrode for itself can be moved, but that a common interrupter is provided for the three regulating devices with three coupled contact disks, the contact segments of which are offset by 120 'from one another, so that regulation takes place intermittently and alternately in the three phases of the series.

   



   PATENT CLAIMS:
1. Arrangement to avoid over-regulation in automatic regulating devices in which the regulation takes place intermittently, characterized in that by a special, from the actual
 EMI2.1
