Description

Elektromagnetischer Strombegrenzer mit intermittierender Unterbrechung, bei dem eine Hauptstromspule mit geringer Windungszahl bei eintretender Überlastung die Kurzschlußverbindung einer zweiten, den Netzstromkreis unterbrechenden Spule aufhebt, dadurch gekennzeichnet, daß sowohl die Öffnung und Schließung des Kurzschlußkontaktes (12) für die Kurzschlußspule (2) als auch die öffnung und Schließung des Unterbrechungskontaktes (5) des Netzstromkreises erst nach Zurücklegung eines bestimmten Weges durch die Anker (3 und 9) der Spulen (1 und 2) erfolgt.Electromagnetic current limiter with intermittent interruption in which a main current coil with a low number of turns in the event of an overload, the short-circuit connection of a second, the Mains circuit interrupting coil cancels, characterized in that both the opening and closing of the short-circuit contact (12) for the short-circuit coil (2) as well as the opening and closing of the interruption contact (5) of the mains circuit takes place only after covering a certain distance through the armature (3 and 9) of the coils (1 and 2).

Claims (1)

Patentanspruch:Claim: durch Einstellung des Ankers 3 mit der Feder 4 durch die Stellschraube 10 bestimmt werden kann, zieht die Spule 1 den Anker 3 an, so daß die Feder 12 vom Kontakt 11 abgehoben wird. Nunmehr liegt die Spule 2 im Stromkreis und zieht den Kern 9 an, der mit seinem Anschlag 16 den Hebel 5 mitnimmt und die Verbindung mit dem Kontakt 8 unterbricht. Hierdurch geht die Feder 6 über den Totpunkt und hält den Hebel 5 so lange, bis durch Abfallen des Kernes 9 der Anschlag 15 den Hebel wieder mitnimmt.can be determined by adjusting the armature 3 with the spring 4 through the adjusting screw 10 can, the coil 1 attracts the armature 3, so that the spring 12 is lifted from the contact 11. The coil 2 is now in the circuit and attracts the core 9, which with its stop 16 the lever 5 takes along and the connection with the contact 8 interrupts. This is how the Spring 6 over the dead center and holds the lever 5 until the core 9 falls off Stop 15 takes the lever with it again. Die Anordnung hat den Vorteil, daß normal nur eine verhältnismäßig kleine Spule 1 im Stromkreis liegt, wodurch der Spannungsabfall gering bleibt und erst bei eintretender Überlastung die eigentliche Arbeitsspule in den Stromkreis eingeschaltet wird.The arrangement has the advantage that normally only a relatively small coil 1 in the Circuit, which means that the voltage drop remains low and only when an overload occurs the actual work coil is switched on in the circuit.
