Description

Bei der Verwendung von Relais, die mit Hilfe von Widerständen oder von parallel geschalteten Kondensatoren verzögert sind, hat man in vielen Fällen ein Interesse daran, die für die Anzugsverzögerung eins Relais wirksamen Mittel zu überprüfen, um sicherzustellen, daß die gewünschte Verzögerungszeit zwischen dem Einschaltvorgang und der Kontaktgabe ,des zu verzögernden Relais eingehalten wund.When using relays with the help of resistors or are delayed by capacitors connected in parallel, one has in many cases an interest in the means effective for the pick-up delay of a relay check to make sure the desired delay time between the switch-on process and the contact making of the relay to be delayed is observed sore.

Gemäß der Erfindung kann dies dadurch erreicht werden, da,ß man nicht das in Frage kommende Steuerrelais, sondern ein Hilfsrelais durch Vorschalten eines Widerstandes und Parallelschelten eines. Kondensators in bekannter Weise verzögert anziehen läßt und dann dem eigentlichen Steuerrelais über den nunmehr durch das Hilfsrelais aufgeladenen Kondensator einen Aufladestromstoß gibt, worauf der Anker das Steuerresai&, anzieht. Durch geeignete Wahl der Wicklung des .Steuerrelais und der Größe des Kondensators kann man eine Mindestaufladung des Kondensators festlegen, bei der das Steuerrelais gerade noch anzieht. Durch die Begrenzung der Kondensatoraufladung nach unten hat man aber gleichzeitig eine Kontrolle darüber, ob das. Hilfsrelais und damit auch das Steuerrelais eine bestimmte Mindestvarzögerungszeit für den Ankeranzug hat.According to the invention, this can be achieved because, ß one not the control relay in question, but an auxiliary relay by connecting one upstream Resistance and parallel scolding one. Capacitor delayed in a known manner can tighten and then the actual control relay via the now through the Auxiliary relay charged capacitor gives a charging surge, whereupon the armature the tax repository &, attracts. By suitable selection of the winding of the control relay and the size of the capacitor, a minimum charge of the capacitor can be determined, at which the control relay still picks up. By limiting the charging of the capacitor downwards one has at the same time a control over whether the auxiliary relay and thus also the control relay a certain minimum delay time for the anchor tightening Has.

Ein Ausführungsbeispiel gibt die Zeichnung wieder. Der Kontakt S soll den Stromkreis schließen. Der Anker des Steuerrelais B soll aber erst nach beispielsweise 3 Sekunden anziehen. Schließt der Kontakt S den Stromkreis, so wird zuerst der Kondensator C über den Widerstand W langsam aufgeladen. Erst nach bestimmter Zeit, hier z. B. nach 3 Sekunden, wenn der Kondensator eine genügend: große Aufladung hat, zieht der Anker des Hilfsrelais H an. Dadurch wechselt der Umschaltkontakt Hl seine Stellung, und nun entlädt sich der Kondensator C über die Wicklung des Steuerrelais B; dessen Anker zieht an und legt durch den KontaktBi die Wicklung des Relais B an Spannung.The drawing shows an exemplary embodiment. Contact S should close the circuit. The armature of the control relay B should, however, only after, for example Tighten for 3 seconds. If the contact S closes the circuit, the capacitor becomes first C slowly charged through resistor W. Only after a certain time, here z. B. after 3 seconds, when the capacitor has a sufficiently high charge, pulls the armature of the auxiliary relay H on. As a result, the changeover contact Hl changes its position, and now the capacitor C discharges through the winding of the control relay B; whose Armature picks up and applies voltage to the winding of relay B through contact Bi.

Würde im Stromkreis des Kondensators C ein Drahtbruch od. dgl. vorliegen, käme keine Auf-Ladung des Kondensators zustande und das Steuerrelais B bliebe abgefallen und würde hierdurch eine Störung anzeigen. Auch jede Störung am Köndenr sator selbst würde sich hierbei bemerkbar machen. Gleichzeitig ist man: in der Lage, eine Störung, also z. B. einen Kurzschluß des Widerstandes W, festzustellen. Zu diesem Zweck kann man eine Sicherung M vorsehen, die infolge des plötzlichen Stromstoßes, sobald der Widerstand W überbrückt ist, durchbrennt. Statt dar Sicherung kann man, auch ein Reläis verwenden, das nur bei dem plötzlichen Stromstoß zum Anziehen kommt.If there were a wire break or the like in the circuit of the capacitor C, the capacitor would not be charged and the control relay B would remain de-energized and would thereby indicate a malfunction. Also every fault on the core aerator itself would be noticeable here. At the same time you are: able to resolve a fault, so z. B. a short circuit of the resistor W to determine. To this end can you provide a fuse M, which as a result of the sudden current surge, as soon as the Resistance W is bridged, burns out. Instead of a backup, you can also use a Use a relay that only pulls in when there is a sudden surge of electricity.
