Description
Ansprechhilfsschaltung für ein Auxiliary response circuit for a
Relais. Relay.
Gegenstand der Erfindung ist eine Ansprechhilfsschaltung für ein Relais.The invention relates to an auxiliary response circuit for a relay.
Wenii ein Relais aus größerer Entfernung, d.h. über längere Zuleitungen angesteuert werden muß, reich-t oft bei gegebener Betriebsspanrlung die am Ende der Zuleiturlyeil verfügbare elektrische Energie nicht mehr aus, das Relais zum Ansprechen u bringen, obwohl sie zum Halten des Relais noch ausreichen würde.Wenii a relay from a greater distance, i.e. over longer supply lines must be controlled, often enough at the end of the given operating voltage the supply line available electrical energy is no longer off, the relay to Trigger u, although it would still be sufficient to hold the relay.
Die der Erfindung zugrunde liegende Aufgabe besteht darin, eine einfach aufgebaute Ansprechhilfsschaltung für ein Relais zu schaffen, die insbesondere bei über lange Leitungswege anzusteuernden Relais, beispielsweise in Ruf- oder Notrufanlagen, verwendbar ist.The object of the invention is to provide a simple to create built-up auxiliary circuit for a relay, in particular with Relays to be controlled via long cable routes, for example in call or emergency call systems, is usable.
Die Lösung dieser Aufgabe erfolgt erfindungsgemäß mit den im kennzeichnenden Teil des Patentanspruchs angegebenen Merkmale.This object is achieved according to the invention with the in the characterizing Part of the claim specified features.
Wie weiter unten anhand eines Ausführungsbeispiels näher erläutert, ist es mit der erfidunsgemäßen Schaltung möglich, durch Umpolen der an den Zuleitungen anliegenden Gleichspannung die am Ende der Zuleitungen zur Verfügung stehende Spannung automatisch zu verdoppeln, wodurch das Ansprechen des Relais sichergestellt ist. Nuch dem Ansprechen sinkt die Spannung wieder auf den normalen Betriebswert ab.As explained in more detail below using an exemplary embodiment, it is possible with the circuit according to the invention by reversing the polarity of the leads applied DC voltage is the voltage available at the end of the supply lines automatically doubled, whereby the response of the relay is ensured. After responding, the voltage drops back to the normal operating value.
Die erfindungsgemäße Schaltung ist mit großem Vorteil anwendbar, bei Notrufanlagen mit beispielsweise an Landstraßen in größerem Abstand von einer Zentrale aufgestell'uen Notrufsäulen. Bei derartigen Notrufanlagen müssen gewisse Schaltvorgänge, beispielsweise das Wiederausschalterl einer Rundumleuchte, von der Zentrale aus gesteuert werden, wobei in manchen Fällen sowieso ein Umpolen der Spannung scattfindet, was die Anwendung der erfindungsgemäßen Schaltung begünstigt.The circuit according to the invention can be used with great advantage in Emergency call systems with, for example, on country roads at a greater distance from a control center set up Emergency telephones. With such emergency systems must certain switching processes, for example switching a rotating beacon off again, can be controlled from the control center, in some cases reversing the polarity anyway the voltage scattfinds, which favors the use of the circuit according to the invention.
Im folgenden wird anhand der Zeichnungeil ein Ausführungsbeispiel der erfindungsgemäßen Schaltung näher erläutert.In the following an exemplary embodiment is given with reference to the drawing the circuit according to the invention explained in more detail.
Es zeigen: Fig. 1 eine Ansprechhilfsschaltung im Ruhezustand; Fig. 2 die Ansprechhilfsscialtung nach Fig. l im Arbeitszustand in der Ansprechphase und Fig. 3 die Ansprechhilfsschaltung nach Fig. 1 im Arbeitszustands in der Haltephase.1 shows an auxiliary response circuit in the idle state; Fig. 2 the response assistance system according to FIG. 1 in the working state in the response phase and FIG. 3 shows the auxiliary response circuit according to FIG. 1 in the operating state in the holding phase.
-en Bei den in den Fig. 1 bis 3 dargestellten Schaltung sind die Enden l und 2 einer Relaiswicklung W an Zuleitungen L1 und L2 angeschlossen, deren Leitungswiderstand symbolisch mit R1 und R2 bezeichnet ist. -en In the circuit shown in Figs. 1 to 3 are the Ends l and 2 of a relay winding W connected to leads L1 and L2, whose Line resistance is symbolically denoted by R1 and R2.
Das Ende l der Relaiswicklung W ist mit der Kathode einer Diode D2 verbunden, deren Anode mit der Zuleitung L2 verbunden ist. Das Ende 2 der Relaiswicklung W ist mit: der Anode einer Diode D3 verbunden, deren Kathode mit der Zuleitung Ll verbunden ist. Weiterhin ist ein Kondensator C einerseits mit dem Ende l der Relaiswicklung W und andererseits mit der Zuleitung L2 verbunden, d.h. er ist parallel zur Diode D2 geschaltet. Die mit dem Ende 1 der Relaiswicklung W verbundene Elektrode des Kondensators C ist weiterhin mit der Kathode einer Diode Dl verbunden, deren Anode mit der Zuleitung L1 verbunden ist.The end l of the relay winding W is connected to the cathode of a diode D2 connected, the anode of which is connected to the lead L2. The end 2 of the relay winding W is connected to: the anode of a diode D3, the cathode of which is connected to the lead Ll connected is. Furthermore, a capacitor C is on the one hand with the end l of the relay winding W and on the other hand connected to the lead L2, i.e. it is parallel to the diode D2 switched. The electrode of the connected to the end 1 of the relay winding W Capacitor C is also connected to the cathode of a diode Dl, the anode of which is connected to the feed line L1.
In Fig. 1 ist die Schaltung im Ruhezustand dargestellt, indem die Betriebsspannung U so angelegt ist, daß an der Zuleitung Ll positives und an der Zuleitung L2 negatives Potential liegt. iii diesem Zustand wird der Kondensator C über die Diode Dl auf die Betriebsspannung U aufgeladen.In Fig. 1, the circuit is shown in the idle state by the Operating voltage U is applied so that at the Lead Ll positive and there is a negative potential on the lead L2. iii this state becomes the capacitor C charged to the operating voltage U via the diode Dl.
Ein Ansprechen des Relais W wird dabei durch die Diode D3 verhindert.A response of the relay W is prevented by the diode D3.
Wenn das Relais angesteuert werden soll, wird die Betriebsspannung U umgepolt und die Schaltung befindet sich im Arbeitszustand. In Fig. 2 ist der erste Teil dieses Arbeitszustandes, die Ansprechphase des Relais dargestellt. In diesem Zustand addiert sich die Betriebsspannung U zu der durch die Aufladung des Kondensators C an diesem erzeugten Spannung zu einer Spannung vom Wert 2U Dies hat zur Folge, d-aß durch die Relaiswicklung W ein Strom fließt, der zum Ansprechen des Relais ausreicht.When the relay is to be controlled, the operating voltage U reversed and the circuit is in working condition. In Fig. 2 is the first part of this working state, the response phase of the relay is shown. In In this state, the operating voltage U is added to that generated by the charging of the Capacitor C at this generated voltage to a voltage of the value 2U this has As a result, a current flows through the relay winding W which is necessary to respond of the relay is sufficient.
Nach dem Anziehen des Relais und der Entladung des Kondensators C übernimmt die Diode D2 den durch die Relaiswicklung W gehenden Stromfluß, wobei zum Halten des Relais die normale Betriebsspannung U ausreicht. Dieser Zustand ist in Fig. 3 dargestellt.After pulling in the relay and discharging the capacitor C the diode D2 takes over the current flow going through the relay winding W, wherein the normal operating voltage U is sufficient to hold the relay. This state is shown in Fig. 3.
Der Kondensator C wirkt also wie eine in der Ansprechphase des Relais kurzzeitig in Serie zur Betriebsspannung geschaltete Batterie mit der Klemmenspannung U.The capacitor C thus acts like one in the response phase of the relay Battery connected briefly in series to the operating voltage with the terminal voltage U.
