Description

Bei der tonfrequenten Fernsteuerung von Starkstromnetzen ist es bekannt, die Empfänger an das Starkstromnetz über einen Serienresonanzkreis anzuschließen, der auf die Frequenz der überlagerungsspannung abgestimmt ist und für diese einen verhältnismäßig niedrigen, für die Frequenz der Netzspannung jedoch einen verhältnismäßig hohen Widerstand darstellt. Meistens werden die tonfrequenten Resonanzspannungen des Resonanzkreises, z. B. mit Hilfe von Gleichrichterverstärkern, weiterverarbeitet zur Auslösung der gewünschten Schaltoperation.In the audio-frequency remote control of power networks, it is known to connect the receivers to the power network via a series resonant circuit, which is tuned to the frequency of the superimposed voltage and for this one relatively low, for the frequency of the mains voltage, however, a relatively low one represents high resistance. Most often the audio frequency resonance voltages of the resonance circuit, e.g. B. processed with the help of rectifier amplifiers to trigger the desired switching operation.

Es sind auch schon Fernsteuerempfänger bekannt, bei denen die Induktivität des Resonanzkreises durch die Wicklung eines tonfrequenten Resonanzrelais gebildet wird, mit dessen Hilfe die Schaltoperationen unmittelbar eingeleitet werden können. Ein solcher Resonanzkreis ist in Fig. i der Zeichnung dargestellt. Der Serienresonanzkreis, bestehend aus der Kapazität C und der Relaisinduktivität R, ist mit seinen Klemmen i, i' an das Starkstromnetz N, z. B. ein 22o-V-Netz, angeschlossen. Der Kontakt r des Resonanzrelais arbeitet z. B. über einen nicht näher dargestellten Synchronwähler S direkt auf den Leistungsschalter.There are also known remote control receivers in which the inductance of the resonance circuit formed by the winding of an audio frequency resonance relay with the help of which the switching operations can be initiated immediately. Such a resonance circuit is shown in Fig. I of the drawing. The series resonance circle, consisting of the capacitance C and the relay inductance R, is with its terminals i, i 'to the power network N, z. B. a 22o-V network connected. The contact r of the resonance relay works z. B. via a synchronous selector, not shown S directly on the circuit breaker.

Derartigen Anordnungen, bei denen die Wicklung des Resonanzrelais zugleich ganz oder zum Teil die Induktivität des auf die Tonfrequenz abgestimmten Resonanzkreises bildet, haftet jedoch ein schwerwiegender Nachteil an. Die Induktivität der Relaiswicklung hängt nämlich von der jeweiligen Stellung des Relaisankers ab, ändert sich also, wenn- der Relaisanker aus dem abgefallenen Zustand in die Ansprechlage übergeht. Das bedeutet, daß sich die ursprüngliche Abstimmung des Resonanzkreises beim Ansprechen des Relais ändert und die Spitze der Resonanzkurve bei abgefallenem Relais bei einer anderen Frequenz liegt als bei angezogenem Relaisanker. Um diese Schwierigkeit zu vermeiden, ist es bekannt, durch einen magnetischen Nebenschluß zum Anker des Relais das Verhältnis des mit der Ankerlage veränderlichen Ankerflusses zum Gesamtfluß und damit auch die verhältnismäßige Änderung der Induktivität der Relaiswicklung in Abhängigkeit von der Ankerlage herabzusetzen.Such arrangements in which the winding of the resonance relay at the same time wholly or partly the inductance of the tuned to the audio frequency Forms resonance circuit, however, has a serious disadvantage. The inductance the relay winding depends on the respective position of the relay armature, So changes when the relay armature moves from the dropped state to the response position transforms. This means that the original tuning of the resonance circuit changes when the relay responds and the peak of the resonance curve when it has dropped out Relay is at a different frequency than when the relay armature is attracted. Around Difficulty avoiding it is known by a magnetic shunt to the armature of the relay is the ratio of the armature flux that changes with the armature position to the total flow and thus also the relative change in the inductance of the Relay winding to be reduced depending on the armature position.

Die Erfindung bezweckt, bei Fernsteuerempfängern, bei denen die Induktivität des Resonanzrelais zugleich die Induktivität des auf die Tonfrequenz abgestimmten Resonanzkreises bildet, die Rückwirkung von Stellungsänderungen des Relaisankers auf die Abstimmung des Resonanzkreises auf andere Weise zu vermindern. Das wird gemäß der Erfindung dadurch erreicht, daß der das Wechselstromrelais enthaltende Relaisserienresonanzkreis des Empfängers einerseits direkt mit einem ersten Netzleiter und andererseits mit einem Abgriff einer Induktivität verbunden ist, die mit einem an den zweiten Netzleiter angeschlossenen Kondensator in Reihe liegt und mit diesem einen ü-eiteren Serienresonanzkreis bildet, wobei der Abgriff so gewählt ist, daß die an der Induktivität abgegriffene Tonfrequenzspannung annähernd den gleichen Wert aufweist, wie die am Eingang dieses Serienresonanzkreises liegende Spannung der tonfrequenten Befehlsimpulse.The invention aims at remote control receivers in which the inductance of the resonance relay at the same time the inductance of the tuned to the audio frequency Forms resonance circuit, the reaction of changes in position of the relay armature to reduce the tuning of the resonance circuit in other ways. That will achieved according to the invention in that the AC relay containing Relay series resonance circuit of the receiver on the one hand directly to a first network conductor and on the other hand is connected to a tap of an inductance that is connected to a connected to the second power line capacitor is in series and with this forms a ü-eiteren series resonance circuit, the tap being chosen so that the audio frequency voltage tapped at the inductance is approximately the same Has value, such as the voltage present at the input of this series resonant circuit of the audio-frequency command pulses.

Der Gegenstand des Patentanspruchs ist nur in seiner Gesamtheit als Erfindung zu werten; ein Elementenschutz wird nicht beansprucht.The subject of the claim is only in its entirety as To evaluate invention; element protection is not claimed.

Die Fig. 2 zeigt eine beispielsweise Ausführung der Erfindung. Der Relaisresonanzkreis ist über einen Abgriff a an einen Teilbetrag der Induktivität L angeschlossen, die zusammen mit der Kapazität C1 den mit den Klemmen 2, 2' an das Netz angeschlossenen Serienresonanzkreis bildet.Fig. 2 shows an exemplary embodiment of the invention. Of the Relay resonance circuit is via a tap a to a portion of the inductance L connected, which together with the capacitance C1 is connected to the terminals 2, 2 ' the network connected series resonance circuit forms.

Die Wirkung der Induktivitätsänderung des Relais R auf den Resonanzkreis Cl, L ist nun erlieblich verringert.The effect of the change in inductance of the relay R on the resonance circuit Cl, L is now considerably reduced.
