Description
Verfahren zum Übertragen von einphasigen tonfrequenten Überlagerungsenergien für die Fernsteuerung mittels Resonanzrelais von einem Teil eines Dreiphasennetzes nach einem anderen Es ist bekannt, Resonanzrelais über bestehende Leitungen durch tonfrequente Überlagerungsströme fernzusteuern. Um die im Netz befindlichen Stromerzeuger und Stromverbraucher nicht mit tonfrequenter Energie mitspeisen zu müssen, hat man für die Resonanzrelais eine eigene Rückleitung, z. B. die Erde, gewählt.Method for the transmission of single-phase audio-frequency superimposition energies for remote control by means of resonance relays from part of a three-phase network according to another it is known to use resonance relays over existing lines remotely control audio-frequency superimposed currents. To the power generators in the network and you don't have to feed power consumers with audio-frequency energy a separate return line for the resonance relay, e.g. B. the earth, chosen.
In Drehstromnetzen, bei welchen die Nutzstromverbraucher über Niederspannungstransformatoren gespeist werden, ergibt sich die Notwendigkeit, die tonfrequenten Steuerströme über die vorhandenen Netztransformatoren hinüberzuleiten. Zu diesem Zweck ist bereits vorgeschlagen worden, die Transformatorwicklungen durch besondere kleine Einphasentransformatoren, die in geeigneter Weise zwischen Ober- und Unterspannungsseite der Netztransformatoren und Erde geschaltet sind, für die tonfrequenten Steuerströme zu überbrücken.In three-phase networks, in which the utility current consumers via low-voltage transformers are fed, there is the need to transfer the audio-frequency control currents to transfer the existing network transformers. To this end is already it has been proposed to replace the transformer windings with special small single-phase transformers, the appropriate way between the high and low voltage side of the power transformers and earth are connected to bridge the audio-frequency control currents.
Auf Grund der Erfindung erfolgt die Übertragung unter Verzicht auf Hilfstransformatoren dadurch, daß man die Netzteile durch Netztransformatoren. in Stern-Stern-Schaltung kuppelt und deren Sternpunkte erdet. Dadurch wird erreicht, daß jeder dieser Dreiphasentransformatoren für die überlagerte Energie ebenso wirkt wie je drei parallel geschaltete Einphasentransformatoren. Die Arbeitsweise eines solchen zweifach ausgenutzten Transformators kann man sich folgendermaßen veranschaulichen.Due to the invention, the transfer takes place without Auxiliary transformers by converting the power supplies through power transformers. in Star-star connection couples and their star points are grounded. This achieves that each of these three-phase transformers acts for the superimposed energy in the same way like three single-phase transformers connected in parallel. The way a Such a doubly used transformer can be illustrated as follows.
Die dreiphasige Netzenergie wird in bekannter Weise transformiert. Die überlagerte einphasige Energie ruft in den drei Schenkeln drei gleichphasige, gleichgerichtete Kraftlinienflüsse hervor, welche sowohl die Hochspannungs- wie die Niederspannungswicklung durchfließen und daher eine Transformation der überlagerten Energie entsprechend den Windungsverhältnissen des Transformators bewirken. Diese in den Schenkeln erregten, zusätzlichen Kraftlinienflüsse haben bei den üblichen Dreischenkeltransformatoren nicht die Möglichkeit, sich in dem lamellierten Eisenkern zu schließen, sondern werden, da sie gleich groß und gleichgerichtet sind, sich zum Teil durch die Luft, zum Teil durch die Befestigungsschrauben des Eisenkernes und über das Eisengehäuse des Transformators schließen. Dies ist möglich, weil im Verhältnis zur Größe des Kraftlinienflusses, der vom Netzstrom herrührt, der Kraftlinienfluß der überlagerten Energie sehr klein ist, beispielsweise weniger als z Prozent des von einer Phase des Netzstromes induzierten Kraftlinienflusses beträgt.The three-phase network energy is transformed in a known manner. The superimposed single-phase energy calls in the three legs three in-phase, rectified lines of force flows, which both the high voltage as flow through the low voltage winding and therefore a transformation of the superimposed Effect energy according to the turns ratios of the transformer. These have additional lines of force flows excited in the thighs with the usual Three-legged transformers do not have the option of being in the laminated iron core to close, but because they are equal in size and in the same direction, they become themselves partly through the air, partly through the fastening screws of the iron core and close over the iron casing of the transformer. This is possible because im Relation to the magnitude of the flux of the lines of force that originates from the mains current, the flux of the lines of force the superimposed energy is very small, for example less than z percent of the line of force flux induced by a phase of the mains current is.
In der beiliegenden Zeichnung ist eine Anlage gemäß der Erfindung dargestellt. Durch den Tonfrequenzerzeuger a .wird über den Transformator b der tonfrequente Strom auf den Erdleiter des - Primärnetzes aufgedrückt. Um den Übergang des tonfrequenten Stromes von der Hochspannungsseite auf die Niederspannungsseite über den Netztransformator d zu ermöglichen, werden beide Sternpunkte des Transformators d an Erde gelegt. Auf der Niederspannungsseite sind die Resonanzrelais g gezeichnet, welche für sich ebenfalls mit der Erde verbunden sind.In the accompanying drawing is a plant according to the invention shown. The audio frequency generator a. Is transmitted via the transformer b of the audio-frequency current pressed onto the earth conductor of the primary network. To make the transition of the audio-frequency current from the high-voltage side to the low-voltage side Via the mains transformer d, both neutral points of the transformer are enabled d laid to earth. The resonance relays g are drawn on the low-voltage side, which are also connected to the earth for themselves.
