Claims (1)

<Desc/Clms Page number 2> Sekundärwicklungen gleicher Phase gegeneinander geschaltet und dass in die Verbindungsleitungen Relais in Brückenschaltung angeschlossen sind und dass schliesslich beim Stromdurchgang durch die Relais ein Hilfsstromkreis geschlossen wird, der die in den Wechselstromzuleitungen sowie in den Gleichstromleitungen liegenden Schalter öffnet. <Desc / Clms Page number 2> Secondary windings of the same phase are switched against each other and that relays are connected in a bridge circuit in the connecting lines and that finally an auxiliary circuit is closed when the current passes through the relays, which opens the switches in the alternating current supply lines and in the direct current lines. 3. Schutzschaltung nach Anspruch 2 für Umformer, deren Gleichstromspannung mit Hilfe vorgeschalteter Drosselspulen geregelt wird, dadurch gekennzeichnet, dass auf die Drosselspulen aufgebrachte Sekundärwicklungen zur Speisung der Auslöserrelais dienen. EMI2.1 3. Protection circuit according to claim 2 for converters whose DC voltage is regulated with the aid of upstream choke coils, characterized in that secondary windings applied to the choke coils are used to feed the trip relays. EMI2.1
