Description
Schaltung-'zur-Übertragung von tonfrequenten Steuerenergien über Netztransformatoren, die in Stern-Stern geschaltet sind und eine in Polygon geschaltete Tertiärwicklung enthalten Die Erfindung betrifft eine Schaltung zur Übertragung von tonfrequenten Steuerenergien über Transformatoren, die beiderseits in Stern .geschaltet sind und eine in Polygote geschaltete Tertiärwicklung enthalten.Circuit for the transmission of audio-frequency control energies via network transformers, which are connected in star-star and a tertiary winding connected in polygon The invention relates to a circuit for the transmission of audio frequencies Control energies via transformers, which are connected in star on both sides and contain a tertiary winding connected in polygotes.
Es ist bereits vorgeschlagen worden, in Netzen, bei denen die Überlagerungsspannung zwischen der Erde als einem Leiter und den Phasenleitungen des Starkstromnetzes zusammengenommen als anderem: Leiter aufgedrückt wird, die tonfrequenten Ströme dadurch über die im Netz befindlichen Transformatoren zu übertragen, daß man die Sternpunkte der Netztransformatoren erdet, gegebenenfalls unter Zwischenschaltung von Kondensatoren. Auch hat man vorgeschlagen, Aden Netztransformator durch einen Hilfstransformator zu überbrücken, der mit seinen Wicklungen je zwischen dem Sternpunkt oder einem künstlichen Sternpunkt und der Erde eingeschaltet ist.It has already been proposed in networks where the superimposition voltage between the earth as a conductor and the phase lines of the power network Taken together as other: conductor is pushed open, the audio-frequency currents to transmit through the transformers located in the network, that one the The neutral points of the network transformers are earthed, if necessary with interconnection of capacitors. It has also been proposed to Aden mains transformer through a Auxiliary transformer to bridge, with its windings depending between the star point or an artificial star point and the earth is switched on.
Diese Schaltung ist bei Transformatoren in Stern-Sternschaltung, die mit einer in Polygon geschalteten Tertiärwicklung versehen sind, nicht anwendbar, weil in dieser Tertiärwicklung die Steuerenergie vernichtet würde. Denn in der Tertiärwicklung, die beispielsweise bei Drehstromtransformatoren auf drei Sehenkel des Transformators verteilt ist, wird in jeder Spule durch die ankom= mende Steuerenergie eine elektromagnetische Kraft induziert, welche mit den in den beiden anderen Schenkeln induzierten elektromagnetischen Kräften phasengleich ist. Diese drei Spannungsvektoren schließen sich also nicht wie bei Drehstrom zu einem Vektordreieck, so daß bei symmetrischer Belastung die resultierende Spannung gleich Null ist, in der Tertiärwid,#lung also kein Strom fließt, sondern die von der Steuerenergie herrührenden Flüsse induzieren in der Tertiärwicklung und bei allen Belastungszuständen gleichgerichtete elektromotorische Kräfte, die sich algebraisch für den Tertiärstromkreis addieren und einen sehr starken Kurzschlußstrom hervorrufen, der die zugeführte Steuerenergie verzehrt und eine Übertragung nach der anderen Transformatorseite unmöglich macht.This circuit is used in transformers in star-star circuit, the are provided with a tertiary winding connected in a polygon, not applicable, because the control energy would be destroyed in this tertiary development. Because in the tertiary development, in three-phase transformers, for example, on three legs of the transformer is distributed, the incoming control energy creates an electromagnetic coil in each coil Force induced, which with the induced in the other two legs electromagnetic Forces is in phase. So these three voltage vectors do not close as with three-phase current to a vector triangle, so that with symmetrical loading the The resulting voltage is zero, i.e. no current in the tertiary resistor flows, but the flows resulting from the control energy induce in the Tertiary winding and rectified electromotive under all load conditions Forces that add up algebraically for the tertiary circuit and a very strong one Cause short-circuit current that consumes the supplied control energy and a Making transmission to the other side of the transformer impossible.
Erfindungsgemäß wird bei derartig geschalteten Netztransformatoren die Übertragung der Steuerenergie von der einen auf die andere Transformatorseite dadurch ermöglicht, daß in das Polygon der Tertiärwicklung die eine Wicklung eines Hilfstransformators eingeschaltet wird, dessen andere Wicklung in an sich bekannter Weise in einer der beiden die Transformatorsternpunkte mit ,der Erde verbindenden Leitungen eingeschaltet ist.According to the invention, network transformers connected in this way the transfer of the control energy from one side of the transformer to the other thereby made possible that in the polygon of the tertiary winding one winding Auxiliary transformer is switched on, the other winding of which is known per se Way in one of the two connecting the transformer star points with the earth Lines is switched on.
Die Anordnung soll an Hand der beiliegenden Zeichnung erläutert werden.The arrangement is to be explained with reference to the accompanying drawing.
Mit R, S, T sind die drei Phasen der Hochspannungsseite bezeichnet, . mit U, Tl, W die drei Phasen der Mittel- oder Niederspannungsseite. Der SternpunktS, der Hochspannungsseite und der Sternpunkt S2 der Mittel- bzw. Niederspannungsseite sind gegebenenfalls über einen Kondensator C, bzw. C2 mit der Erde verbunden. Inder Hochspannungsseite ist in die Verbindungsleitung vom Hochspannungssternpunkt S, zur Erde die primäre Wicklung eines Transformators Z, eingeschaltet, die sekundäre Wicklung Z. dieses Transformators ist mit der Tertiärwicklung 0 in Reihe geschaltet. Der Zusatztransformator Z" Z= kann aber auch in die Verbindungsleitung des Sternpunktes S, zur Erde angeordnet sein.With R, S, T the three phases of the high voltage side are designated,. with U, Tl, W the three phases of the medium or low voltage side. The star point S on the high voltage side and the star point S2 on the medium or low voltage side are optionally connected to earth via a capacitor C or C2. On the high voltage side, the primary winding of a transformer Z is connected in the connection line from the high voltage star point S to earth, the secondary winding Z of this transformer is connected in series with the tertiary winding 0. The additional transformer Z "Z = can also be arranged in the connection line of the star point S to earth.
