Description

Rückmeldevorrichtung für durch überlagerungsfernsteuerung fernbediente Leistungsschalter Es ist bekannt, überlag.erungsfernsteueranlagen mit einem besonderen Rückmeldesystem derart auszuführen, daß die Empfangsstelle selbsttätig der Sendestelle noch vor der eigentlichen Signalgabe rüclnneldet, welcher Schaltakt ausgelöst werden wird. So hat man beispielsweise nach einem bekannten Vorschlag an der Empfangsstelle einen oder mehrere Verteilerarme angeordnet, die mittels eines Motors über Kontaktreihen bewegt werden. Der die Kontaktarme antreibende Motor wird durch eine von der Sendestelle kommende Vorbereitungsfrequenz über ein Resonanzorgan in Tätigkeit gesetzt. Mit den Verteilerorganen ist ein Regleraxm für leinen Rückmeldegenerator derart verbunden, daß jeder Verteilerarmstellung eine bestimmte Rückmeldefrequenz zugeordnet ist. Unter Umständen kann dabei gleichzeitig die Anordnung so getroffen sein, daß durch die Rückmeldefrequenzen die jeweilige Stellung der Verteilerarme in der Sendestelle erkennbar gemacht und bei Erreichen der gewünschten Stellung der in der Empfangsstelle angeordneten Verteilerarme die Vorbereitungsfrequenz unterbrochen und hierauf der eigentliche Schaltakt durch Aussendung einer Steuerfrequenz von der Sendestelle aus bewirkt wird. Diese Art der Rückmeldung ist immerhin nach verhältnismäßig kompliziert.Feedback device for remote control by overlay remote control Circuit breaker It is known to overlay remote control systems with a special To perform the feedback system in such a way that the receiving station automatically matches the sending station even before the actual signal is given, it reports which switching act is triggered will. So you have, for example, according to a known suggestion at the receiving point one or more distributor arms arranged by means of a motor via rows of contacts be moved. The motor that drives the contact arms is powered by one of the transmitting station upcoming preparatory frequency set in action via a resonance organ. With A regulator axm for a feedback generator is connected to the distribution organs in such a way that that each distributor arm position is assigned a specific feedback frequency. Under certain circumstances, the arrangement can be made so that through the feedback frequencies the respective position of the distributor arms in the transmission point made recognizable and when the desired position is reached in the receiving office arranged distributor arms interrupted the preparation frequency and then the actual switching act by sending a control frequency from the transmitting station is effected from. After all, this type of feedback is relatively complicated.

Nach einem anderen bekannten Vorschlag werden in überlagerungsfernsteuer,anlagenbei fernbedienten Leistungsschaltern als Rückmeldung die Änderungen des überlagerungsstromes benutzt, die sich dadurch ergeben, 4ß sich beim öffnen oder Schließen eines solchen Schalters zwangsläufig die Widerstands-, insbesondere die Kapazitätswerte dies Netzes infolge Abtrennung oder Zuschaltung eines Netzteils ändern. Die Erfindung besteht in einer besonders vorteilhaften Anzeigevorrichtung für die auf diese Weise durchgeführte Rückmeldung.According to another well-known proposal, overlay remote control is included remotely controlled circuit breakers as feedback, the changes in the superimposed current used, which result from the opening or closing of such a Switch inevitably the resistance, especially the capacitance values of this network change due to disconnection or connection of a power supply unit. the Invention consists in a particularly advantageous display device for the feedback carried out in this way.

Erfindungsgemäß sind bei einem Differentialgerät, dessen beide Stromkreise vom überlagerungsstrom beeinflußt sind, die Zeitkonstanten dieser Stromkreise verschieden groß gemacht.According to the invention are in a differential device, its two circuits are influenced by the superimposed current, the time constants of these circuits are different made great.

An Hand des in der Zeichnung dargestellten Ausführungsbeispiels soll die Erfindung näher erläutert werden.On the basis of the embodiment shown in the drawing the invention will be explained in more detail.

i ist der Generator des Netzes N mit den Abzweigungen 2, 3, q., die durch je einen Leistungsschalter 20, 30, 4.o mittels eines Resonanzrelais 21, 31,q.1 von der Steuerzentrale Z aus in bekannter Weise fernbedient werden können. Der überlagerungsstrom wird mittels der Sperrkreissch.altung 5 durch das Sendeaggregat 6 aufgedrückt, das mittels eines Kommandoschalters 7 auf die verschiedenen Kommandos eingestellt werden kann. 8 ist das Differentialrelais mit dem Zeiger (Relaisanker) 9 und den beiden Wicklungen i o, i i, die über die Wandler 12, 13 mit dem Aufdrückkreis des Senders 6 gekoppelt sind. Im Stromkreis der Wicklung io liegt der Ohmsche Widerstand 14 und parallel zur Sekundärwicklung des Wandlers 12 ist der Kondensator 15 geschaltet. Im Stromkreis der Wicklung i i dagegen liegt die Induktivität 16. Der Stromkreis der Wicklung io hat deshalb eine wesentlich kleinere Zeitkonstante als der Stromkreis der Wicklung i i. Der Zeiger g steuert mittels Kontakten die Signallampen 17, 18. An Stelle der Signallampen 17, 18 können auch Teile eines Leuchtschaltbildes mit Selbsthaltestromkreis, Flackerlichter u. dgl. treten.i is the generator of the network N with branches 2, 3, q., the each by a circuit breaker 20, 30, 4.o by means of a resonance relay 21, 31, q.1 can be operated remotely from the control center Z in a known manner. The overlay current is pressed by means of the locking circuit circuit 5 by the transmission unit 6, the can be set to the various commands by means of a command switch 7 can. 8 is the differential relay with the pointer (relay armature) 9 and the two Windings i o, i i, which are connected to the transducers 12, 13 with the pressure circuit of the transmitter 6 are coupled. The ohmic resistance 14 is located in the circuit of the winding io and the capacitor 15 is connected in parallel with the secondary winding of the converter 12. In the circuit of winding i i, however, there is inductance 16. The circuit the winding io therefore has a much smaller time constant than the circuit the winding i i. The pointer g controls the signal lamps 17, 18 by means of contacts. Instead of the signal lamps 17, 18, parts of a luminous circuit diagram can also be used Self-holding circuit, flickering lights and the like.

Die Vorrichtung arbeitet folgendermaßen: Es soll beispielsweise der Schalter 2o für die Abzweigleitung 2 durch Sendung der Frequenz 31oHertz eingelegt werden. Dann wird der Kommandoschalter 7 auf die entsprechende Schaltung, z. B. »Schalter 20 ein«, @eingestellt und damit das Netz N mit 31o Hertz überlagert. Das Einsetzen des überlagerungsstrome.s ruft einen ersten Ausschlag des Zeigers 9 hervor, der- nach kurzer Zeit abklingt und ein Beweis für die Anwesenheit des Überlagerungsstromes ist. Sobald das Relais 21 anspricht und den Schalter 2o schließt, nimmt das NetzN infolge Zuschaltung der Leitung 2 mehr überlagerungsstrom auf. Auf diese Stromzunahme stellt sich wegen der kleineren Zeitkonstante der Kreis der Wicklung to rascher ein als der der Wicklung i i. Der Zeiger 9 wird also im Drehsinn des eingezeichneten Pfeils ausschlagen und die Lampe 17 zum Aufleuchten bringen. Sobald auch der Stromkreis der Wicklung i i mit der größeren Zeitkonstante sich dem neuen Cberlagerungsstro.m angepaßt bat, verschwindet wieder der Zeigerausschlag.The device works as follows: It should, for example, the Switch 2o for branch line 2 inserted by sending the frequency 31oHertz will. Then the command switch 7 is on the appropriate circuit, z. B. "Switch 20 on", @ set and thus superimposed the network N with 31o Hertz. That The start of the superimposition current causes the pointer 9 to deflect for the first time, which decays after a short time and is evidence of the presence of the superimposed current is. As soon as the relay 21 responds and closes the switch 2o, the NetzN as a result of the connection of line 2, more superimposed current. On this increase in electricity Because of the smaller time constant, the circle of the winding turns out to be faster a than that of the winding i i. The pointer 9 is so drawn in the direction of rotation Turn out the arrow and light up the lamp 17. As soon as the circuit of the winding i i with the larger time constant follows the new superimposing current adjusted, the pointer deflection disappears again.

Wird umgekehrt der Schalter 2o, beispielsweise durch überlag erung von 37o Hertz, geöffnet, dann nimmt wegen Abschaltung der Leitung 2 der Cberlagerungsstrom ab, das Feld der Wicklung io geht schneller zurück, während das der Wicklung i i noch erhalten bleibt. Der Zeiger 9 schlägt also entgegen der Pfeilrichtung aus, und die Lampe i8 wird betätigt.If the switch 2o is reversed, for example by overlaying of 37o Hertz, open, then because line 2 is switched off, the superimposed current increases from, the field of winding io decreases faster, while that of winding i i still remains. The pointer 9 therefore moves against the direction of the arrow, and the lamp i8 is activated.

Wenn auch im Ausführungsbeispiel als Mittel für die Erzielung einer kleinen oder großen Zeitkonstante nur Induktivitäten, Widerstände und Kapazitäten angegeben sind, so können doch, .tun einen genügend großen Unterschied in der Zeitkonstante he rlyeizuführ:en, auch alle übrigen, für solche Zwecke gebräuchlichen Mittel verwendet werden, z. B. Röhrenschaltungen. Auch kann man den von den Wandlern 12, 13 gelieferten Sekundärstrom zuvor gleichrichten und die größere Zeitkonstante für das Feld der Wicklung i i durch einen Kurzschlußring auf dem Eisenkern und ähnliche Mittel herbeiführen. Da solche Mittel aus der Relaistechnik bekannt sind, soll hier nicht näher darauf eingegangen werden.Even if in the exemplary embodiment as a means for achieving a small or large time constant only inductances, resistances and capacitances are given, they can make a sufficiently large difference in the time constant He rlyeizuführ: en, also all other means used for such purposes be e.g. B. Tube circuits. The ones supplied by the transducers 12, 13 can also be used Rectify secondary current beforehand and the larger time constant for the field of Bring winding i i through a short-circuit ring on the iron core and similar means. Since such means are known from relay technology, we will not go into detail here To be received.

Die Erfindung bietet den Vorteil, daß ohne Zuhilfenahme von besonderen Leitungen, Rückmeldesendern usw. eine zuverlässige Rückmeldung erzielt wird und daß trotz der Kürze der als. Rückmeldeimpuls ausgenutzten Überlagerungsstromänderung eine genügend lange und bei Anwendung von Selbsthaltungen sogar bleibende Rückmeldeanzeige herbeigeführt wird.The invention offers the advantage that without the aid of special Lines, feedback transmitters, etc. a reliable feedback is achieved and that despite the brevity of the as. Feedback pulse utilized superimposed current change a sufficiently long and, if self-locking, even permanent feedback display is brought about.
