Description

DEUTSCHESGERMAN

Bei Hochspannungs - Kraftübertragungen werden vielfach Transformatoren in Sparschaltung verwendet, um von diesen verschiedene Spannungen abnehmen zu können. Es ist bei langen Überlandleitungen oft notwendig, die zur Übertragung verwendete Spannung nachträglich zu ändern. Dies kann ohne weiteres dadurch geschehen, daß man die Sekundärwicklung des Haupttransformators mit einer zwischen dieser Wicklung und Erde geschalteten Sekundärwicklung eines Zusatztransformators in Reihe schaltet, dessen Primärwicklung von derselben Spannungsquelle gespeist wird wie die Primärwicklung des Haupttransformators. Dies hat aber den Nachteil, daß auch die übrigen vom Haupttransformator entnommenen Spannungen gleichzeitig geändert werden. Da jedoch die Spannung für ein Versorgungsnetz oder für andere Verbraucher meist nicht geändert werden soll, sondern nur die Übertragungsspannung, so kann ein solcher Zusatztransformator nicht ohne weiteres verwendet werden.In high-voltage power transmissions, transformers are often used in economy circuit, in order to be able to relieve various tensions from these. It is with long power lines it is often necessary to subsequently change the voltage used for transmission. This can easily done by the secondary winding of the main transformer with a between this winding and earth connected secondary winding of an additional transformer in Series switches whose primary winding is fed by the same voltage source as the primary winding of the main transformer. But this has the disadvantage that the rest of the main transformer extracted voltages can be changed at the same time. However, since the tension for one The supply network or for other consumers should usually not be changed, only the transmission voltage, such an additional transformer cannot be used without further ado.

Die Erfindung betrifft eine Transformatoranordnung für Hochspannungs-Kraftübertragungen, mit der die höchste Spannung auf der Sekundärseite der Transformatoranordnung erhöht werden kann, ohne dadurch die übrigen von der Transformatoranordnung entnommenen Spannungen zu ändern. Nach der Erfindung geschieht dies dadurch, daß die Sekundärwicklung des Haupttransformators mit mehreren Sekundärwicklungen eines Zusatztransformators so in Reihe geschaltet wird, daß eine Sekundärwicklung des Zusatztransformators die erforderliche Zusatzspannung zur Spannungserhöhung liefert und die übrigen Sekundärwicklungen des Zusatztransformators Spannungen ergeben, die, von den an den Anzapfungen der Sekundärwicklung des Haupttransformators auftretenden Spannungen abgezogen, die Ausgangsspannungen für das Ortsnetz oder gewisse Verbraucher auf ihren ursprünglichen Wert halten oder gegebenenfalls auf einen anderen gewünschten Wert bringen. Die Primärwicklung des Zusatztransformators wird dabei von derselben Spannungsquelle gespeist wie die Primärwicklung des Haupttransformators. The invention relates to a transformer arrangement for high-voltage power transmissions, with which the highest voltage on the secondary side of the transformer arrangement can be increased without thereby changing the remaining voltages drawn from the transformer arrangement. According to the invention this happens because the secondary winding of the main transformer with several Secondary windings of an additional transformer is connected in series so that a secondary winding of the Additional transformer supplies the additional voltage required to increase the voltage and the rest Secondary windings of the additional transformer result in voltages that, from the taps of the Voltage occurring in the secondary winding of the main transformer is deducted, the output voltages for the local network or certain consumers at their original value or if necessary, bring it to another desired value. The primary winding of the auxiliary transformer is fed from the same voltage source as the primary winding of the main transformer.

Die Transformatoranordnung nach der Erfindung sei im folgenden an Hand der Zeichnung erläutert. Sie zeigt einen Haupttransformator 1 mit einer von einem Generator 3 gespeisten Primärwicklung 2. Alit 4 ist die Sekundärwicklung, des Haupttransformators bezeichnet. Sie hat eine Klemme 5 zur Abnahme der Fernübertragungsspannung und eine Anzapfung 6 für den Anschluß eines örtlichen Versorgungsnetzes oder eines anderen Verbrauchers. 7 ist ein Zusatztransformator mit einer Primärwicklung 8, die an dieselbe Spannungsquelle angeschlossen ist wie Transf o rmator ano r dnung
für Hodispannungs-Kraftübertragungen
The transformer arrangement according to the invention is explained below with reference to the drawing. It shows a main transformer 1 with a primary winding 2 fed by a generator 3. Alit 4 is the secondary winding of the main transformer. It has a terminal 5 for taking off the remote transmission voltage and a tap 6 for connecting a local supply network or another consumer. 7 is an additional transformer with a primary winding 8 which is connected to the same voltage source as the transformer ano r extension

die Primärwicklung 2 des Haupttransformators 1, mit einer ersten Sekundärwicklung 9 zwischen Erde und der Sekundärwicklung 4 des Haupttransformators 1 und mit einer zweiten Sekundärwicklung 10, die -einpolig an die Anzapfung 6 der Sekundärwicklung 4 des Haupttransformators 1 angeschlossen ist. Die beiden Spannungen in den Sekundärwicklungen 9 und 10 des Zusatztransformators 7 sind einander entgegengerichtet, so daß die Spannung in der Sekundärwicklung 9 zu der Spannung in der Sekundärwicklung 4 addiert wird, während die Spannung in der Sekundärwicklung 10 von der an der Anzapfung 6 entnommenen Spannung subtrahiert wird. Man kann es dabei so einrichten, daß ungeachtet der Spannungserhöhung, die an der Klemme 5 für die Fernübertragung erhalten wird, die Spannung an der Klemme 11 entweder unverändert bleibt oder einen willkürlichen Wert bekommt. Klemme 11 übernimmt also nach der Zuschaltung des Zusatztransformators 7 die Aufgabe der Anzapfung 6 des Haupttransformators 1 und dient somit der nunmehr zum Anschluß des örtlichen Versorgungsnetzes oder anderer Verbraucher, deren Spannung gegenüber der Fernübertragungsspannung niedriger und gleichbleibend sein soll.the primary winding 2 of the main transformer 1, with a first secondary winding 9 between earth and the secondary winding 4 of the main transformer 1 and with a second secondary winding 10, the single pole is connected to the tap 6 of the secondary winding 4 of the main transformer 1. The two Voltages in the secondary windings 9 and 10 of the additional transformer 7 are opposite to each other, so that the voltage in the secondary winding 9 becomes the voltage in the secondary winding 4 is added, while the voltage in the secondary winding 10 differs from that at the tap 6 taken voltage is subtracted. You can set it up so that regardless of the voltage increase applied to terminal 5 for remote transmission is obtained, the voltage at terminal 11 either remains unchanged or an arbitrary one Gets value. Terminal 11 takes over after the connection of the additional transformer 7 Task of the tap 6 of the main transformer 1 and is therefore now used to connect the local supply network or other consumers, their voltage compared to the remote transmission voltage should be lower and constant.
