Description

Einrichtung zur Fernanzeige von Schalterstellungen u. dgl. mittels Hochfrequenzströmen. Es ist häufig %v ichtig, in einem Kraftwerk oder einer Unterstation die Stellung eines Schalters zu kennen, durch den ein Verbraucher am Ende der Speiseleitung angeschlossen wird. Man kann hierzu vorteilhaft Hochfrequenzschwingungen benutzen, die der Fernleitung durch einen in der Nähe de:. Schalters aufgestellten Röhrensender gegebenenfalls nach Verstärkung durch eine Verstärkerröhre aufgedrückt werden. Der Schalter, dessen Stellung angezeigt werden soll, besitzt zu diesem Zwecke Hilfskontakte, die sich beim Abfallen des Schalters schließen und hierdurch beispielsweise die Primärwicklungen der Anoden- und Gitterkreise des Röhrensenders und des Verstärkers speisen. Der Verstärker speist beispielsweise die Primärwicklung eines regelbaren Kopplungstran#;forinators. Die Sekundärwicklung des letzteren ist einerseits über einen Bloekkendensator an die Fernleitung und andererseits über eine Abstimmdrossel an Erde gelegt. In dem letztgenannten Stromkreis liegt zweckmäßig noch ein weiterer vom Schalter gesteuerter Hilfskontakt. Bei geschlossenem Schalter ist also die gesamte Sonderanordnung abgeschaltet und verbraucht keineEnergie. Beim Abfallen des Schalters werden durch die Sonderanordnung Hochfrequenzschwingungen erzeugt und längs der Fernleitung nach dem Kraftwerk oder der Unterstation fortgeleitet, wo eine geeignete Empfangsanordnung vorgesehen ist. Den Gegenstand der Erfindung bildet nun eine besondere Ausbildung dieser Empfangsanordnung, von welcher ein Ausführungsbeispiel in der Zeichnung dargestellt ist.Device for remote display of switch positions and the like by means of High frequency currents. It is often% important in a power plant or substation to know the position of a switch through which a consumer at the end of the feed line is connected. High-frequency vibrations can be used advantageously for this purpose, that of the pipeline through a nearby de :. Tube transmitter set up by a switch may be pressed on after reinforcement by an intensifier tube. Of the The switch, the position of which is to be displayed, has auxiliary contacts for this purpose, which close when the switch falls and thereby, for example, the Primary windings of the anode and grid circuits of the tube transmitter and the amplifier Food. The amplifier feeds, for example, the primary winding of a controllable Coupling tran #; forinators. The secondary winding of the latter is one hand over a block capacitor to the pipeline and on the other hand via a tuning choke laid on earth. In the last-mentioned circuit there is expediently another one Auxiliary contact controlled by the switch. When the switch is closed, the entire Special arrangement switched off and does not consume any energy. When the switch falls are generated by the special arrangement high-frequency vibrations and along the Pipeline forwarded to the power plant or substation where appropriate Receiving arrangement is provided. The subject of the invention now forms a special one Formation of this receiving arrangement, of which an embodiment in the Drawing is shown.

In dieser bedeutet i die Sammelschiene des Kraftwerkes oder der Unterstation, an welche über einem Schalter 2 die Fernleitung 3 angeschlossen ist. Der Einfachheit halber ist nur eine Phase dargestellt. Die dargestellte Phase der Sammeischienen ist über einen Blockkondensator q., die Primärwicklung 5 eines Kopplungstransformators und eine Abstimmdrossel 6 geerdet, durch welch letztere der eben genannte Stromkreis auf die Frequenz der ankommenden Schwingungen abgestimmt werdeji kann. Die Sekundärwicklung 7 speist einer. Stromkreis, der ein Entladungsgefäß 8, die Wicklung g eines Relais und die Sekundärwicklung io eines Transformators enthält, durch welchen diesem Kreis eine geeignete, annähernd konstante, aber einstellbare Spannung aufgedrückt wird. Die Primärwicklung i i dieses Transformators liegt an einer beliebigen Spannungsquelle. Im Nebenschluß zur Sekundärwicklung 7 des Kopplungstransformators liegt ein Kondensator 1z, durch welchen der Sekundärkreis auf die Frequenz der zu empfangenden Ströme abgestimmt werden kann.In this i means the busbar of the power plant or the substation, to which the long-distance line 3 is connected via a switch 2. Of simplicity only one phase is shown for the sake of The illustrated phase of the bus bars is via a block capacitor q., the primary winding 5 of a coupling transformer and a tuning choke 6 grounded, through which the latter the circuit just mentioned can be tuned to the frequency of the incoming vibrations. The secondary winding 7 one feeds. Circuit comprising a discharge vessel 8, the winding g of a relay and the secondary winding io contains a transformer through which this circuit a suitable, approximately constant, but adjustable voltage is applied. The primary winding i i of this transformer is connected to any voltage source. Shunted to the secondary winding 7 of the coupling transformer lies a capacitor 1z, through which the secondary circuit to the frequency of the to be received Currents can be tuned.

Das Entladungsgefäß 8 ist in irgendeiner der bekannten Weisen unsymmetrisch auszubilden, so daß es zwischen seinen zwei Elektroden im allgemeinen nur Ströme in einer Richtung durchläßt. Zu diesem Zwecke können die beiden Elektroden beispielsweise umgleich groß sein, oder es kann die eine Elektrode mit einem das Kathodengefälle herabsetzenden Oxyd bedeckt sein. Das Glasgefäß ist zweckmäßig mit Neon oder einem anderen trägen Gas bei vermindertem Druck gefüllt. Das Gas, sein Druck und die den Elektroden durch die Sekundärwicklung io aufgedrückte Spannung sind so gewählt, daß diese Spannung etwas unterhalb derjenigen liegt, bei welcher eine Entladung durch dfas Gefäß hindurchgeht. Wenn nun an der entfernten Stelle der Schalter abfällt und hierdurch der Fernleitung 3 Hochfrequenzschwingungen zugeführt werden, dann werden diese im Kraftwerk bzw. in der Unterstation aufgenommen, und es wird durch -denKopplungstransformator 5, ; dem Entladungsgefäß 8 eine zusätzliche Spannung aufgedrückt, und dies genügt nun, um eine Entladung durch das Gefäß hervorzurufen. Es fließt daher durch die Relaiswicklung 9 Strom so lange, als die Hochfrequenzschwingungen empfangen werden. Das Relais 9 schließt seinen Kontakt 13 und hierdurch einen Ortsstromkreis, der von einer Stromquelle i,. über ein Relais 15 führt. Das Relais 15 kann irgend eine Anzeigevorrichtung in Tätigkeit setzen, beispielsweise eine Lampe 16 einschalten, indem es seinen Kontakt 17 schließt.The discharge vessel 8 is asymmetrical in any of the known ways so that there are generally only currents between its two electrodes in one direction. For this purpose, the two electrodes can, for example the same size, or it can be one electrode with a cathode slope degrading oxide must be covered. The glass vessel is useful with neon or a other inert gas filled at reduced pressure. The gas, its pressure and the Electrodes imposed by the secondary winding io voltage are chosen so that that this voltage is slightly below that at which a discharge passes through the vessel. If now the switch falls off at the remote point and high-frequency vibrations are thereby supplied to the long-distance line 3, then these are taken up in the power plant or in the substation, and it is through -the coupling transformer 5,; the discharge vessel 8 an additional voltage pressed open, and this is now sufficient to cause a discharge through the vessel. Current therefore flows through the relay winding 9 as long as the high-frequency oscillations be received. The relay 9 closes its contact 13 and thereby a local circuit, from a current source i ,. via a relay 15 leads. The relay 15 can any activate a display device, e.g. switch on a lamp 16, by closing its contact 17.

Wie sich aus Vorstehendem ergibt, verbraucht auch die Empfangsanordnung im Ruhestand keinen nennenswerten Strom. Ferner können sämtliche Hilfsstromquellen der Empfangsanordnung ,Wechselstromquellen sein, auch dort, wo in der Zeichnung der Einfachheit halber Gleichstromquellen eingezeichnet sind. Der Wechselstrom kann dem Netz selbst entnommen werden.As can be seen from the above, the receiving arrangement also consumes no significant electricity in retirement. Furthermore, all auxiliary power sources the receiving arrangement, alternating current sources, also where in the drawing DC sources are shown for the sake of simplicity. The alternating current can taken from the network itself.
