Description
Anordnung von Empfangsrelais für Fernsteuerung mittels Trägerströmen In Anlagen für zentralisierte Fernsteuerung durch den Energieverteilungsnetzen überlagerte modulierte Trägerströme ist die Verwendung von Empfangsrelais bekannt, welche auf einen Mod.ulationstakt abgestimmte Drehpendel besitzen.Arrangement of receiving relays for remote control by means of carrier currents Superimposed in systems for centralized remote control through the power distribution networks modulated carrier currents, the use of receiving relays is known, which on have a rotary pendulum that is coordinated with a modulation cycle.
Um die Anzahl der fernzusteuernden Schalthandlungen zu erhöhen, muß man die Anzahl von Modulationsta'kten erhöhen, was dazu nötigt, daß man die Frequenzen dieser Takte einander möglichst nähert.In order to increase the number of switching operations to be remotely controlled, the number of modulation stages is increased, which means that the frequencies of these bars as close as possible to each other.
Um eine gute Auswahl dieser verschiedenen Takte erreichen zu können, muß man die Seleiktivität der Drehpendel der Empfangsrelais erhöhen. Zur Erhöhung dieser Selektivität muß man jedoch die diesen Drehpendeln bei jedem Impuls zugefifrte Energie vermindern, so daß die Ansprechzeit beträchtlich zunimmt, und dies führt zu Sendedauern, die sich verbieten, insbesondere wenn die Sendungen nacheinander -d'qrch je ein Speisekabel durchgeführt werden.In order to be able to achieve a good selection of these different measures, you have to increase the selectivity of the rotary pendulum of the receiving relay. To increase this selectivity, however, must be given to these rotary pendulums with each pulse Decrease energy so that the response time increases considerably, and this leads To broadcast durations that are prohibited, especially if the programs are one after the other -d'qrch a feeder cable must be passed through.
Um diese Schwierigkeiten zu beleben, sieht die Erfindung eine Anordnung zum Empfang der modulierten Sendungen vor, bei welcher ,die den Drehpendeln bei jedem Halbwechsel der Modulation mitgeteilte Energie genau 'konstant und von den Änderungen des Empfangspegels der Steuersignale und den Spannungsänderungen des Verteil.ungsnetzes. unabhängig ist.To enliven these difficulties, the invention provides an arrangement to receive the modulated broadcasts before, in which, the rotating pendulums at energy communicated to each half-change of the modulation exactly 'constant and from the Changes in the reception level of the control signals and the changes in voltage of the Distribution network. is independent.
Unter diesen Umständen ist es, da die Drehpendel der Empfangsrelais eine gegebene Selektivität für eine ebenfalls gegebene Ansprechzeit haben, möglich, daB man die Modulationstakte einander soweit wie möglich nähert ohne die Gefahr, daB auf einen Nachbartakt übergegriffen wird. Die Anordnung von Empfangsrelais gemäß der Erfindung kennzeichnet sich dadurch, daß sie ein Organ zur Auswahl der Steuerträgerfrequenz aufweist, welches ein elektromagnetisches Hilfsrelais im Modulationstakt erregt. Der bewegliche Anker dieses elektromagnetischen Relais, dessen Hub, z. B. durch :\nschläge, genau festgelegt ist. verschiebt den Befestigungspunkt der Spirale eines 1)rhpendelrelais und überträgt so eine bestimmte Energie, die von den Pegeländerungen des Steuersignals und von den Änderungen der Spannung des Verteilungsnetzes unabhängig ist.In these circumstances it is as the rotary pendulum of the receiving relay have a given selectivity for a given response time, possible, that the modulation cycles are brought as close as possible to one another without the risk of that it encroaches on a neighboring clock. The arrangement of Receiving relay according to the invention is characterized in that it is an organ to select the control carrier frequency, which has an electromagnetic auxiliary relay excited in the modulation cycle. The moving armature of this electromagnetic relay, its stroke, e.g. B. by: \ nschlag, is precisely defined. moves the attachment point the spiral of a 1) pendulum relay and thus transmits a certain energy that of the level changes of the control signal and of the changes in the voltage of the Distribution network is independent.
Weitere Einzelheiten und Vorteile der Erfindung ergeben sich aus der folgenden Beschreibung eines Ausführungsbeispieles an Hand der Zeichnung.Further details and advantages of the invention emerge from the following description of an embodiment based on the drawing.
In der Zeichnung ist i ein Schwingzungenrelais, das in bekannter Weise eine mechanisch auf die Frequenz des Steuerträgerstromes abgestimmte Zunge 2 besitzt. Diese Zunge ist an einem Pol eines Magnets 3 befestigt und wird von einer auf einem magnetischen Kreis 5 angeordneten Spule 4 erregt.In the drawing, i is a vibrating tongue relay that works in a known manner has a tongue 2 that is mechanically tuned to the frequency of the control carrier current. This tongue is attached to one pole of a magnet 3 and is one on one Magnetic circuit 5 arranged coil 4 excited.
Diese Spule 4 ist in Reihe mit einem Kondensator 6 an die Klemmen des Energieverteilungslletzes 7 und 8 geschaltet und bildet mit diesem Kondensator einen auf die Frequenz des Trägerstromes abgestimmten Resonanzkreis. Die Schwingzunge 2 stellt mit einer Gegenzunge io, deren Eigenperiode gegen diejenige der Schwingzunge 2 niedrig ist, einen Kontakt 9 her. Der Kontakt ist normalerweise geschlossen. Wenn ein Steuerstrom mit der Schwingungsfrequenz der Schwingzunge 2 die Spule 4 @durchftießt, gelangt diese Zunge in Resonanz und schwingt mit einer gewissen Amplitude. Der Kontakt 9 wind bei jeder Schwingung unterbrochen.. Die Wicklung i i eines elektromagnetischen Relais, die normalerweise durch den Kontakt 9 kurzgeschlossen und in Reihe mit einem Widerstand 12 an die Klemmen 7, 8 des Energieverteiliungsnetzes geschaltet ist, wird erregt, wenn die Schwingzunge 2 in Resonanz gelangt.This coil 4 is in series with a capacitor 6 across the terminals of the energy distribution network 7 and 8 connected and forms with this capacitor a resonance circuit tuned to the frequency of the carrier current. The swinging tongue 2 represents with a counter tongue io, the natural period of which is opposite to that of the oscillating tongue 2 is low, make a contact 9. The contact is normally closed. if a control current with the oscillation frequency of the oscillating tongue 2 flows through the coil 4 @, this tongue comes into resonance and vibrates with a certain amplitude. The contact 9 winds interrupted with every oscillation .. The winding i i of an electromagnetic Relays normally shorted by contact 9 and in series with one Resistor 12 is connected to terminals 7, 8 of the power distribution network, is excited when the vibrating tongue 2 resonates.
Die Wicklung ii zieht einen Anker 12 mit einem durch die Anschläge 13 und 14 begrenzten Hub an. Wenn der Anker 12 auf seinen Anschlag 14 gelangt, verschiebt er den Befestigungspunkt der Spirale 17 des Drehpendels, welches die Modulationstakte auswählt. Dieses Drehpendel besteht im wesentlichen aus einer Masse 16, die mit einer zu der Bildebene senkrechten Achse 15 fest verbunden ist, aus einer Spiralfeder 17, deren äußerer Befestigungspunkt mit (lern Anker 12 fest verbunden ist, und ans einem den beweglichen Kontakt i9 tragenden Arm 20. Das Tr'iglieitsmotnent der Masse 16 und das Drehmoment der Spiralfeder 17 sind so bestimmt, claß die Schwingungsperiode des beweglichen Teils des Drehpendelrelais dein Modulationstakt entspricht.The winding ii attracts an armature 12 with a stroke limited by the stops 13 and 14. When the armature 12 comes to its stop 14, it moves the attachment point of the spiral 17 of the rotary pendulum, which selects the modulation clocks. This rotary pendulum consists essentially of a mass 16, which is firmly connected to an axis 15 perpendicular to the plane of the drawing, of a spiral spring 17, the outer attachment point of which is firmly connected to the armature 12 and to an arm 20 carrying the movable contact 19 The Tr'iglieitsmotnent of the mass 16 and the torque of the spiral spring 17 are determined so that the period of oscillation of the movable part of the rotary pendulum relay corresponds to the modulation cycle.
Wenn der bewegliche Teil des Drehspindelrelais in Resonanz gelangt. gelangt rler 1>ew-egliche Konrakt i9 auf den festen l@c»itakt iS.When the moving part of the spindle relay gets into resonance. rler 1> perpetual contract i9 comes to the firm l @ c »itakt iS.
Die Wirkungsweise der =\iiordnung ist die folgende: \\'enn ein modulierter Steuerträgerstrotn, dessen Sendefrequ:nz rler Eigenfrequenz der Schwingzunge 2 entspricht, (lein Energieverteilungsnetz überlagert wird, gelangt die Zunge 2 in Resonanz und öffnet den Kontakt 9 im Takt der Modulation. Der Elekti-oniaanet ii wird nach diesem Takt erregt, und der` Anker 12 verschieht sich zwischen seinen An:chlii-c ii i 3 und i -i ebenfalls nach diesem 'Pakt, wobei er das Ende der Spirale 17 mitnimmt. Diese überträgt auf das Drehpendel 16 eine bestimmte Energie,, die sowölil unabhängig von den Änderungen des Steuersignalpegels als auch von den Änderungen der Spannung des En@e,rgieverteiltin gsnetzes an den Klemmen 7 und 8 ist.The mode of operation of the order is as follows: if a modulated one Control carrier trotn, whose transmission frequency corresponds to the natural frequency of the vibrating tongue 2, (If an energy distribution network is superimposed, the tongue 2 comes into resonance and opens contact 9 in time with the modulation. The Elekti-oniaanet ii will after this Clock excited, and the 'anchor 12 shifts between its An: chlii-c ii i 3 and i-i also according to this' pact, taking the end of the spiral 17 with him. This transmits a certain energy to the rotary pendulum 16, which is independent from the changes in the control signal level as well as from the changes in the voltage of the energy distribution network at terminals 7 and 8.
Wenn die Eigenperiode des beweglichen Teils des Dre'hpendelrelais dein Takt der Modulation des Trägerstromes entspricht, gelangt das Drehpendel 16 in Resonanz und schließt den Kontakt 18, i9, wodurch die Ausführung der Schalthandlung 'herbeigeführt wird.If the natural period of the moving part of the rotary pendulum relay If the cycle corresponds to the modulation of the carrier current, the rotary pendulum 16 arrives in resonance and closes the contact 18, i9, whereby the execution of the switching action 'is brought about.
