Description

Verfahren zum willkürlichen Fernsehalten in Netzen - Die Erfindung betrifft ein Verfahren zum willkürlichen Fernsehalten in Netzen mit mindestens drei Leitungen, von denen eine die Erde sein kann. Sie hat die Aufgabe, soweit als möglich auch noch bei Netzstörungen den Fernschaltbetrieb aufrechtzuerhalten.Method for arbitrary television viewing in networks - The invention relates to a method for arbitrarily watching TV in networks with at least three Lines, one of which can be earth. She has the task as far as possible to maintain remote switching operation even in the event of network faults.

Die Erfindung macht von der an sich bekannten Erdüberlagerung, beider von einer Stelle des Netzes aus eine Leitung, die nicht die Erde ist, gegen Erde mit netzfremder Frequenz überlagert wird, Gebrauch. Erfindungsgemäß werden die die Schaltung betätigenden, auf die überlagerten Frequenzen abgestimmten Empfangsrelais an sämtliche Leiter des Netzes angeschlossen.The invention makes both of the earth superposition known per se from a point in the network a line that is not earth to earth is superimposed with non-network frequency, use. According to the invention, the The receiving relay that activates the circuit and is tuned to the superimposed frequencies connected to all conductors in the network.

Die Erfindung soll an Hand der Zeichnung näher erläutert werden.The invention will be explained in more detail with reference to the drawing.

R, S, T ist ein Drehstromnetz, mit O ist die Erde angedeutet. Fig. i zeigt im Schema den Sender, die Fig.2 einen Empfänger. i (F ig. i ) ist ein Tonfrequenzgenerator, der über einen auf die zu überlagernde Frequenz abgestimmten Aufdrückkreis mit dem Kondensator 2 und der Drosselspule 3 an dem beweglichen Kontakt q. =eines Wählerschalters mit den feststehenden Kontakten 5 bis 7 angeschlossen ist. Der Kontakt 5 ist mit der Phase R, der Kontakt :6 mit der Phase S und der Kontakt 7 mit der Phase T verbunden. Das Empfangsrelais 8 (Fig. 2) ist in das Dreieck der Sekundärwicklung g von Hilfstransformatoren (z. B. Spannungswandlern) geschaltet, deren in Stern geschaltete Primärwicklungen mit ihrem Sternpunkt geerdet sind.R, S, T is a three-phase network, with O the earth is indicated. Fig. i shows the transmitter in the diagram, and FIG. 2 shows a receiver. i (Fig. i) is a tone frequency generator, which is matched to the superimposed frequency with the Capacitor 2 and the choke coil 3 at the movable contact q. = a selector switch is connected to the fixed contacts 5 to 7. Contact 5 is with phase R, contact: 6 connected to phase S and contact 7 connected to phase T. The receiving relay 8 (Fig. 2) is in the triangle of the secondary winding g of auxiliary transformers (e.g. voltage transformers), their star-connected primary windings are grounded with their star point.

Die Vorrichtung arbeitet folgendermaßen: Solange das Netz nicht gestört ist, kann der Wählerschalter q. bei der Seildung beliebig auf irgendeinen der Kontakte 5; bis 7 umgelegt werden. Es wird dann die betreffende Phase des Netzes von dem Sender i über den Aufdrückkreis 2; 3 gegen Erde überlagert. Die überlagerungsspannung wirkt an den Empfangsstellen auf die an die betreffende Phase angeschlossene Primärwicklung i o ein und induziert in der dazu gehörigen Sekundärwicklung g eine Spannung gleicher Frequenz; die das Relais 8 erregt. Wenn das Relais auf diese Frequenz abgestimmt ist, spricht es an und führt die gewünschte Schaltung aus. Sind .zwei Phasen, z. B. R und S, durch Erdschluß o.:dgl. gestört, dann kann der Fernsteuerbetrieb trotzdem aufrechterhalten werden, indem .man den Wählerschalter q, auf den Kontakt 7 umlegt, der an die nicht gestörte Phase T angeschlossen ist. Auf diese Weise können durch Sendung verschiedener Frequenzen die verschieden ans Netz angeschlossenen Relais ausgewählt und zu verschiedenen Schaltungen veranlaßt werden.The device works as follows: As long as the network is not disturbed the selector switch q. on any of the contacts when forming the rope 5; to 7 are turned over. It then becomes the relevant phase of the network from that Transmitter i over the pressing circle 2; 3 superimposed against earth. The superimposition voltage works at the receiving stations to the one connected to the phase in question Primary winding i o and induces in the associated secondary winding g a Voltage of the same frequency; which energizes relay 8. When the relay is on this frequency is tuned, it responds and carries out the desired circuit. Are two Phases, e.g. B. R and S, by earth fault or the like. disturbed, then the remote control operation can can still be maintained by moving the selector switch q to the contact 7, which is connected to the undisturbed phase T. That way you can by sending different frequencies that are differently connected to the network Relays can be selected and caused to various circuits.

An Stelle der in Fig. 2 dargestellten Empfangsvorrichtung können auch drei, gegebenenfalls auf eine gemeinsame Achse einwirkende Relais verwendet werden, von denen jedes an eine Phase des Netzes angeschlossen ist: Die einzelnen Empfangsrelais können auch zum Teil oder durchweg auf die gleiche Frequenz abgestimmt sein, wenn man die Relais in bekannter Weise mit Zeitwählern o. dgl. versieht, die es gestatten, die Relais selektiv durch verschieden lange Impulse, Impulse verschiedener Zahl oder Zeitabstände zu betätigen.Instead of the receiving device shown in FIG. 2, three relays, possibly acting on a common axis, are used, each of which is connected to a phase of the network: the individual receiving relays can also be partially or entirely tuned to the same frequency, if the relays are provided in a known manner with time selectors or the like that allow the relays selectively by impulses of different lengths, impulses of different numbers or to operate time intervals.
