Description
Empfangsrelais für Fernsteueranlagen Es ist ein zum Empfang von Fernsteuerbefehlen dienendes Relais bekannt, das in einer Ausführungsform zwei Wicklungen besizt, die an die gleiche Spannung angeschlossen sind. Der Anker der einen Wicklung ist mit einer mechanischen Dämpfung versehen. Beide Anker sind durch ein Gestänge miteinander verbunden, an dem der bewegliche Teil eines Schaltkontaktes befestigt ist. Ändert sich die Netzspannung so langsam, daß der mit einer Dämpfung versehene Anker nachfolgen kann, daran ändern beide Anker ihre Lage in jedem Augenblick in gleichem Maße, so daß das sie verbindende Gestänge parallel zu sich selbst verschoben wird. Der Schaltkontakt wird infolgedessen nicht betätigt. Ändert sich dagegen die Spannung mit einer bestimmten Mindestgeschwindigkeit, dann bewegt sich unverzögert nur der Relaisanker, der keine Dämpfung besitzt, während der mit einer Dämpfung versehene Relaisanker zurückbleibt. Das die beiden Anker verbindende Geistänge erfährt dadurch eine Verdrehung, so daß der daran befestigte Schaltkontakt geschlossen wird.Receiving relay for remote control systems It is used to receive remote control commands Serving relay known, which possesses two windings in one embodiment, the are connected to the same voltage. The armature of one winding is with mechanical damping. Both anchors are linked by a linkage connected to which the movable part of a switch contact is attached. Changes the mains voltage so slowly that the armature provided with a damping follows can, both anchors change their position to the same extent at every moment, so that the linkage connecting them is moved parallel to itself. The switch contact as a result, is not actuated. If, on the other hand, the voltage changes with a certain value Minimum speed, then only the relay armature moves without delay, the none Has damping, while the relay armature provided with damping remains. The spirit length connecting the two anchors experiences a twist so that the switch contact attached to it is closed.
Dieses Relais wird nach einem Fernsteuerverfahren betrieben, bei dem jeder Schaltbefehl durch eine Senkung und ,eine einige Zeit darauf erfolgende Hebung der Netzspannung gekenlnzeichnet ist. Zwischen diesen beiden Spannungsänderungen bleibt die Spannung einige Zeit abgesenkt, und zwar ist dieser Zeitabstand maßgeblich für den jeweiligen Schaltbefehl. Das erwähnte Relais spricht infolgedessen nur dann und nur so lange an, ,als eine bestimmte Änderungsgeschwindigkeit der Spannung vorhanden ist. Hat die Spannung den abgesenkten Wert erreicht, dann würde sich der Schaltkontakt wieder äffnen, so daß besondere Mittel vorgesehen sein müssen, um ihn bis zu der darauffolgenden Hebung der Spannung geschlossen zu halten.This relay is operated according to a remote control method in which every switching command by a lowering and a subsequent raising the mains voltage is marked. Between these two voltage changes the voltage remains lowered for some time, and this time interval is decisive for the respective switching command. As a result, the mentioned relay speaks only then and only as long as there is a certain rate of change in voltage is. If the voltage has reached the lowered value, the switching contact would be reopen so that special means must be provided to keep him up to the subsequent increase in tension to keep closed.
Das Relais gemäß der Erfindung spricht ebenfalls auf eine bestimmte Änderungsgeschwindigkeit der Netzspannung an und wird in Fernsteueranlagen verwendet. Es wird aber nach einem anderen Fernsteuerverfahren betrieben, und zwar einem solchen, wie es in dem Hauptpatent 7o6270 angegeben ist. Dieses Verfahren besteht darin, daß die Ausführung von unterschiedlichen, von einem oder mehreren Geberorten aus-'' gesandten Kommandos in den einzelnen Empfangsstellen in Abhängigkeit von dem mehrmaligen kurzzeitigen Auftreten bestimmter Spannungsverminderungen und/oder bestimmter Änderungsgeschwindigkeiten der Spannungs- und Stromvektoren des Netzes erfolgt, die sämtlich in bestimmtem zeitlichem Abstand und in bestimmter zeitlicher Folge vorgen@ommen werden. Zur Einwirkung auf die Vektoren werden beispielsweise sehr kurzzeitige Unterbrechungen der Netzleiter verwendet. Bei diesem Verfahren ruft jede Unterbrechung eine Absenkung der Netzspannung hervor, die aber wegen der sofortigen Wiederzuschaltung nur sehr kurze Zeit andauert. Senkung und Hebung der Spannung schließen sich also unmittelbar aneinander an, so daß das bekannte Relais nach diesem Verfahren nicht betrieben werden kann, weil sein Gestänge zuerst nach der einen und anschließend sofort nach der anderen Seite ,ausschlagen würde.. Demgemäß wäre auch die beabsichtigte Fernsteuerwirkung in Frage gestellt.The relay according to the invention also responds to a specific one Rate of change of the mains voltage on and is used in remote control systems used. However, it is operated according to a different remote control method, namely such as it is indicated in the main patent 70270. This method consists in the execution of different, of one or more '' Commands sent to the individual receiving points depending on the location of the encoder the repeated brief occurrence of certain voltage reductions and / or certain rates of change of the voltage and current vectors of the network takes place, all at a certain time interval and at a certain time Follow @ made. To act on the vectors, for example very brief interruptions in the power line are used. In this procedure every interruption causes a lowering of the mains voltage, but this is due to the immediate reconnection lasts only a very short time. Lowering and raising the Voltage are therefore directly connected to each other, so that the well-known relay cannot be operated after this procedure, because its linkage is first after the one and then immediately to the other side, would turn out .. Accordingly the intended remote control effect would also be called into question.
Ein Relais, das auf eine bestimmte Änderungsgeschwindigkeit der Netzspannung anspricht und nach dem Fernsteuer verfahren des Hauptpatents betrieben werden kann, wird erfindungsgemäß so ausgebildet, daß die Vormagnetisierung des Relais in Abhängigkeit von dem absoluten Wert der Spannung verändert wird. Zweckmäßig wird die Anordnung so getroffen, daß ein bei Spannungsänderungen unv erzögert folgernder und ein verzögert folgender Fluß vorgesehen ist, wobei der letztere in einem geschlossenen Eisenkreis fließt.A relay that reacts to a certain rate of change in the mains voltage responds and can be operated according to the remote control method of the main patent, is designed according to the invention so that the premagnetization of the relay as a function is changed by the absolute value of the voltage. The arrangement is expedient made in such a way that one inferred without delay and one delayed in the event of voltage changes the following flow is provided, the latter in a closed iron circle flows.
In der Abbildung ist ein Ausführungsbeispiel des Relais dargestellt. Das Relais besitzt einen geschlossenen Eisenkreis und zwei mittlere Schenkel, zwischen denen der Drehanker angeordnet ist, der unter der Einwirkung einer Feder steht. Die beiden mittleren Schenkel tragen je eine Wicklung, und zwar wird diese unmittelbar von der Wechselspannung des Netzes erregt. Diese beiden Wicklungen erzeugen einen Wechselfluß, der in dem Relaiskern und in dein beiden äußeren Schenkeln den gestrichelt gezeichneten Verlauf hat. Er durchfließt also den mittleren Schenkel von links nach rechts, verzweigt sich dann nach oben und unten und hat in den beiden äußeren Schenkeln die umgekehrte Richtung.The figure shows an embodiment of the relay. The relay has a closed iron circle and two middle legs, between where the rotating armature is arranged, which is under the action of a spring. The two middle legs each carry a winding, and this becomes immediate excited by the AC voltage of the network. These two windings create one Alternating flow, the dashed in the relay core and in your two outer legs has drawn course. So it flows through the middle leg from the left to the left right, then branches up and down and has in the two outer legs the opposite direction.
Auf jedem der beiden äußeren Schenkel ist je eine Wicklung angebracht, und beide Wicklungen sind in der gezeichneten Weise geschaltet. Diese beiden Wicklungen sind mit ihren Klemmen a und b über eine Schal-:tung von Gleichrichtern und Kondensatoren an das Wechselspannungsnetz angeschlossen, p.Uerden also mit Gleichstrom erregt, und zwar folgt wegen der Anwendung von Kondensatoren die Erregung dieser Wicklungen einer etwaigen Spannungsänderung im Netz mit einiger Verzögerung nach-. Diese beiden Wicklungen erzeugen einen Gleichfluß, dessen Verlauf in der Abbildung durch eine punktierte Linie angedeutet ist. Der Gleichfluß schließt sich in dem geschlossenen Eisenkreis, der aus den beiden äußeren Schenkeln besteht, und durchsetzt die mittleren Schenkel nicht. Die Schaltung und Bemessung der beiden Gleichstromwicklungen erfolgt so., daß in keinem Fall an den Klemmen ri und b eine Wechselspannung auftritt.-Tritt eine betriebsmäßige Änderung der Netzspannung ein und sinkt diese entsprechend langsam ab, dann steigt die wirksame Permeabilität des Eisenkerns, so daß der Wechselfluß trotz sinkender Amperewindungszahl konstant bleibt. Demgemäß ändert sich auch die Stellung des Drehankers nicht. Bei schnellen Spannungsabsenkungen, wie sie bei der Aussendung von Schaltbefehlen vorkommen, folgt dagegen die Gleichstrornvormagnetisierung der Änderung der Wechselstrommagnetisierung nur verzögert, so daß eine kurzzeitige Schwächung des Wechselflusses auftritt, die einen Ausschlag des Drehankers zur Folge hat.One winding is attached to each of the two outer legs, and both windings are connected in the manner shown. These two windings are connected with their terminals a and b via a circuit of rectifiers and capacitors to the AC voltage network, i.e. energized with direct current, and because of the use of capacitors, the excitation of these windings follows any voltage change in the network with some delay. These two windings generate a constant flux, the course of which is indicated in the figure by a dotted line. The constant flow closes in the closed iron circle, which consists of the two outer legs, and does not penetrate the middle legs. The circuit and dimensioning of the two direct current windings are carried out in such a way that an alternating voltage never occurs at the terminals ri and b the alternating flow remains constant despite the decreasing number of ampere-turns. Accordingly, the position of the rotating armature does not change either. In the case of rapid voltage drops, as occurs when switching commands are sent, the direct current bias follows the change in the alternating current magnetization only with a delay, so that a brief weakening of the alternating flux occurs, which results in a deflection of the rotating armature.
