Description

Bei Relais mit Anzugsverzögerung durch einen Kondensator tritt die störende Erscheinung auf, daß sich bei einer Spannungsänderung bzw. einem Spannungsabfall die Verzögerungszeit ändert.In the case of relays with a pull-in delay due to a capacitor, the disturbing phenomenon that occurs with a voltage change or a voltage drop the delay time changes.

Die Erfindung bezweckt, diesen Übelstand zu beseitigen, und erreicht dies dadurch, daß wenigstens drei Relaiswicklungen vorgesehen werden, die in der Weise geschaltet sind, daß parallel zu einer Anzugswicklung eine entgegenwirkende Wicklung in Reihe mit dem Kondensator und parallel zum Kondensator eine weitere im Anzugssinne wirkende Wicklung liegt.The invention aims to remedy this drawback and achieves it this in that at least three relay windings are provided in the Are connected in a way that parallel to a pull-in winding a counteracting Winding in series with the capacitor and another in parallel with the capacitor winding acting in the direction of tightening.

Die Anordnung nach der Erfindung und ihre Wirkungsweise ist nachstehend an Hand der Zeichnung noch näher erläutert.The arrangement according to the invention and its mode of operation is as follows explained in more detail with reference to the drawing.

Eine erste Relaiswicklung R1 ist mit dem Kondensator C in Reihe geschaltet. Ihr wirken entgegen die Wicklungen, r1 und R2, wie durch die beigegebenen Pfeile angedeutet ist. Von diesen liegt die Wicklung R2 zu der Reihenschaltung von C und R1 parallel. Zwischen C und R1 ist ein. Abschaltkontakt i des Relais eingezeichnet. Parallel zum Kondensator C liegt die Wicklung r1 zusammen mit einem Widerstand W, der regelbar sein kann. Die Schaltung kann durch einen Handschalter H an Spannung gelegt werden.A first relay winding R1 is connected in series with the capacitor C. It is counteracted by the windings, r1 and R2, as indicated by the arrows is indicated. Of these, the winding R2 is connected to the series circuit of C and R1 parallel. Between C and R1 is a. Shutdown contact i of the relay is shown. In parallel to the capacitor C is the winding r1 together with a resistor W, which can be regulated. The circuit can be powered by a manual switch H. be placed.

Die Wirkungsweise ist folgende. Nach Einlegen des Handschalters fließt ein Strom sowohl über R2, als auch über R1. Solange der Kondensator C sich noch in annähernd entladenem Zustand befindet, ist ein nennenswerter Strom über r1 und W nicht vorhanden. Bald darauf beginnt aber ein solcher über r1 und W zu fließen, um. bei aufgeladenem Kondensator seinen. Höchstwert zu erreichen. Wird nun. angenommen, daß die Spannung abgesunken ist, dann würde dies bedeuten,, daß die Einschaltverzögerung ungewollt verlängert wird, denn der Kondensator kann sich nur langsamer auf seinen Spannungswert aufladen; als -wenn er an einer höheren Spannung läge. -Durch die Erfindung wird aber die Verzögerungszeit genau gleich derjenigen gehalten., die bei konstanter Spannung vorhanden ist. Sobald nämlich ein bemerkenswerter Zweigstrom über y1 und W zu fließen. beginnt, der den Strom in der Wicklung R2 unterstützt (gleiche Richtung der Pfeile von y1 und R2), wird die Herbeiführung einer Schaltbewegung unterstützt und die Schaltbewegung zeitlich früher herbeigeführt, als wenn diese unterstützende Wicklung r1 nicht vorhanden wäre. Das bedeutet also, daß die Ansprechdauer des Relais trotz der durch die fallende Spannung hervorgerufenen vergrößerten Aufladezeit des Kondensators wieder auf das normale Maß zurückgeführt wird.The mode of action is as follows. After inserting the hand switch flows a current through both R2 and R1. As long as the capacitor C is still is in an approximately discharged state, there is a significant current through r1 and W does not exist. Soon afterwards, however, one begins to flow over r1 and W, around. when the capacitor is charged. To achieve maximum value. Will now. accepted, that the voltage has dropped, then this would mean, that the switch-on delay is extended unintentionally, because the capacitor can only slow down on its Charge voltage value; than if it were at a higher voltage. -By that Invention, however, the delay time is kept exactly the same as that is present at constant voltage. As soon as a remarkable branch stream to flow across y1 and W. starts supporting the current in winding R2 (same direction of arrows of y1 and R2), will bring about a switching movement supported and the switching movement brought about earlier than when this supporting winding r1 would not be present. So that means that the response time of the relay despite the increased charging time caused by the falling voltage of the capacitor is brought back to the normal level.
