Description
Anordnung zum Signalisieren, Fernsteuern u. dgl. auf Wechselstromnetzen Die vorliegende Erfindung betrifft ein Verfahren und Anordnungen zum Signalisieren auf Kraftnetzen mittels einer über die normale Netzspannung überlagerten Wechs,elspannung derselben Frequenz wie die Frequenz der Netzspannung.Arrangement for signaling, remote control and the like on AC networks The present invention relates to a method and arrangements for signaling on power networks by means of an alternating voltage superimposed on the normal mains voltage the same frequency as the frequency of the mains voltage.
Die Erfindung ist hauptsächlich dadurch gekennzeichnet, daß der Empfang der ausgesandten Signale, welche durch eine Moiduilatiön einer im Verhältnis zur Netzspannung phasenverschobenen und über dieselbe überlagerten Spannung gebildet werden, in Relais erfolgt, und zwar durch die Zusammenwirkung zwischen einem von- der Netzspannung erzeugten Wechselfelde und der zur Netzspannung senkrechten Komponente des Signalstromes in einer in dem Wechselfelde beweglichen Spule. Die Erfindung ist ferner dadurch gekennzeichnet, daß die in dem Wechselfelde bewegliche Spule mit mechanischen Schwingungsgliedern versehen ist, welche auf die Modulationsfrequenz der Signalspannung abgestimmt sind. Diese Schwingungsglieder sind dann zweckmäßigerwellse mit Kontaktanordnungen versehen, und jedes Schwingungsglied ist für eine der verwandten Modulationsfrequenzen "mechanisch abgestimmt.The invention is mainly characterized in that the reception of the emitted signals, which by a Moiduilatiön one in relation to the Line voltage phase-shifted and formed via the same superimposed voltage are carried out in relays, through the interaction between one of the the alternating fields generated by the mains voltage and the components perpendicular to the mains voltage of the signal current in a coil that can move in the alternating field. The invention is further characterized in that the coil movable in the alternating field is provided with mechanical oscillating members, which on the modulation frequency matched to the signal voltage. These vibrating elements are then more expediently waves provided with contact arrangements, and each vibrating member is for one of the related Modulation frequencies "mechanically tuned.
Die Erfindung ist ferner durch eine . besondere Anordnung für die Erzeugung der überlagerten Signalspannung gekennzeichnet, welche Anordnung von einem an das Netz angeschlossenen Wechselstromgenerator mit Feldwicklung besteht. Diese Feldwicklung wird von einer oder mehreren Erregermaschinen gespeist, welche einen Gleichstromankex haben und eine Feldwicklung, die mixt einem Kondensator oder einer als Kondensator wirkenden Anordnung in Reihe gekuppelt ist.The invention is further through a. special arrangement for the Generation of the superimposed signal voltage indicated which arrangement of a AC generator connected to the grid with field winding. These Field winding is fed by one or more excitation machines, which one Have DC ankex and a field winding that mixes a capacitor or a acting as a capacitor arrangement is coupled in series.
Die Erfindung ist unten unter Hinweis zu den beiliegenden Zeichnungen erläutert.The invention is described below with reference to the accompanying drawings explained.
In Abb. i ist ein Generator für die Erzeugung der modulierten Signalspannung gezeigt.In Fig. I is a generator for generating the modulated signal voltage shown.
Abb. a zeigt eine andere Form des Generators zur Erzeugung der Signalspannung. Abb..3 ist ein Vektordiagramm, das die verschiedenen Spannungen des Generators der Abb. i zeigt.Fig. A shows another form of the generator for generating the signal voltage. Fig..3 is a vector diagram showing the various voltages of the generator's Fig.i shows.
Abb. q. ist ein Diagramm, das den Verlauf der Signalspannung im Verhältnis zu der konstanten Spannung des Netzes zeigt.Fig.q. is a diagram showing the waveform of the signal voltage in relation points to the constant voltage of the network.
Abb.5 ist auch ein Diagramm, das die konstante Spannung und die Signalspannung zeigt, in dem Falle, daß die Modulationsfrequenz höher ist als die Frequenz der normalen Netzspannung.Fig.5 is also a graph showing the constant voltage and the signal voltage shows in the case that the modulation frequency is higher than the frequency of the normal mains voltage.
Abb.6 ist ein Empfangsrelais, dass in solchen Punkten des Netzes benutzt wird, wo die Signalspannung verhältnismäßig hoch iet. Abb.7 zeigt ein Empfangsrelais, welches in solchen Punkten des Netzes benutzt wird, wo die Signalspannung in einen entsprechenden Strom umgewandelt ist, z. B. in unmittelbarer Nähe von einem Generator oder großem Motor.Fig.6 is a receiving relay that is used in such points of the network where the signal voltage is relatively high. Fig.7 shows a receiving relay, which is used in those points of the network where the signal voltage is converted into a corresponding stream, e.g. B. in the immediate vicinity of one Generator or large engine.
Abb.8 ist ein Vektordiagramm, das .die verschiedenen Spannungen zeigt, die in dem Empfangsrelais der Abb.6 wirksam sind.Figure 8 is a vector diagram showing the various voltages which are effective in the receiving relay in Fig. 6.
Abb. g und io sind -Kurven, die die Wirkung des Relais der Abb. 6 erläutern. Durch den Umstand, @daß für die Signale eine überlagerte Spannung benutzt wird, die im Verhältnis zur Netzspannung phasenverschoben ist, wird es möglich, die Feldspule des Empfangsrelals direkt an idas Netz anzuschließen, denn das von einer @so angeschlossenen Spule erzeugte Feld wird beinahe senkrecht zur Netzspannung in Phase liegen. Da jetzt die Signalspannung, die in einer in dem I;eld beweglichen: Spule einen Strom hervorruft, der dieselbe Phase hat wie die Signalspannung, erhält man immer eine auf die Spule wirkende mechanische Kraft, welche die mit der Spule verbundenen Schwingungsglieder in Bewegung versetzt, und zwar wird das Schwingungsglied in Schwingungen kommen, das für die empfangene Modulatioinsfrequenz abgestimmt ist.Fig.g and io are curves showing the action of the relay of Fig. 6 explain. Due to the fact that @ a superimposed voltage is used for the signals phase shifted in relation to the mains voltage, it is possible to to connect the field coil of the receiving relay directly to the network, because that of A field generated by a coil connected in this way becomes almost perpendicular to the mains voltage be in phase. Since now the signal voltage, which is in a movable in the I; eld: Coil produces a current that has the same phase as the signal voltage there is always a mechanical force acting on the coil, which is the same with the coil connected vibrating members set in motion, namely the vibrating member come into oscillation, which is tuned for the received modulation frequency.
Besonders vorteilhaft wird die Anordnung, wenn die Feldspule des Relais, mit einem Kondensator parallel .geschaltet wird und wenn die bewegliche Spule in Reihe mit der Feldspule und dem Kondensator geschaltet wird. Die Feldspule und der Kondensator bilden zusammen, weml sie richtig bemessen werden, einen Sperrkreis für die Netzspannung, so daß die Feldspule beinahe ausschließlich von .einem der Signalspannung entsprechenden Strom durchflossen wird. Durch die Parallelresonanz in dem Sperrkreis wird ferner das Feld senkrecht zu der Netzspannung. Das beste Resultat erreicht man, wenn, die überlagerte Signalspannung genau senkrecht zur Netzspannung liegt, aber auch wenn die Phasenverschiebung weniger als 9o° ist, erhält man doch in der beweglichen Spule eine Stromkomponente, die mit dem Feld in Phase liegt.The arrangement is particularly advantageous when the field coil of the relay, is connected in parallel with a capacitor and when the moving coil is in Series with the field coil and the capacitor is connected. The field coil and the Capacitors together, if correctly dimensioned, form a blocking circuit for the mains voltage, so that the field coil is almost exclusively from one of the Signal voltage corresponding current is flowed through. Due to the parallel resonance in the trap circuit the field is also perpendicular to the line voltage. The best The result is achieved when the superimposed signal voltage is exactly perpendicular to the Mains voltage is present, but is also received if the phase shift is less than 9o ° there is a current component in the moving coil which is in phase with the field lies.
Die Verwendung von mechanisch abgestimmten Schwingungsgliedern setzt eine sehr große Konstanz der Modulation voraus, und diese konstante Modulation wird in einer sehr einfachen Weise durch die obenerwähnten Erregermaschinen mit Kondensatoren in Reihe mit der Feldwicklung erreicht.The use of mechanically tuned vibratory links sets precedes a very great constancy of the modulation, and this constant modulation becomes in a very simple way by the aforementioned exciter machines with capacitors reached in series with the field winding.
