Description

Schalteinrichtung zum Regeln der Spannung von Stufentransformatoren. Im Hauptpatent 271990 ist eine Schalteinrichtung zum Regeln der Spannung von Stufentransformatoren mittels eines Systems von Schaltdrosselspulen beschrieben, das insgesamt mehr als zwei Schenkel hat und das dadurch gekennzeichnet ist, daß die Anzapfungen des Transformators zeitweise an mehrere parallele Stromzweige der Drosselspule angeschlossen werden.Switching device for regulating the voltage of step transformers. In the main patent 271990 is a switching device for regulating the voltage of step transformers described by means of a system of switching inductors that total more than has two legs and is characterized in that the taps of the transformer temporarily connected to several parallel branches of the choke coil.

In dem Ausführungsbeispiel des Hauptpatentes sind als Schaltdrosselspulen Dreifachdrosselspulen dargestellt. Diese Anordnung ist unter Umständen ungünstig insofern, als diese Kraftflüsse durch die verschiedenen Kerne ungleich sind, und die Abmessungen des Transformators der Drosselspule daher groß ausfallen. Eine zweckmäßigere Ausgestaltung der Schaltdrosselspulen ergibt sich, wenn der Erfindung gemäß die an den Anzapfungen des Transformators zeitweise nebeneinanderliegenden Stromzweige aus mehreren magnetisch getrennten Drosselspulen eines aus insgesamt mehr als zwei Schenkeln bestehenden Drosselspulensystems gebildet werden, an deren Mittelpunkten die Enden einer mit den Arbeitsleitungen verbundenen Drosselspule angeschlossen sind. Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung veranschaulicht. t ist der Transformator mit den Anzapfungen a, b, c. An jeder Anzapfung liegen mehrere Schalter, z. B. a', a", parallel, mit Hilfe deren parallel liegende Stromzweige zugleich an dieselben Anzapfpunkte eines Transformators angeschlossen werden. Als Stromzweige dienen die Drosselspulen t1, t2, von denen je die Anfänge z. B. gleichzeitig zu den Schaltern a', ä ' des Anzapfpunktes a führen, die Enden gemeinsam zu der Anzapfung b mit Hilfe der Schalter b', b".In the embodiment of the main patent, triple choke coils are shown as switching inductors. Under certain circumstances, this arrangement is unfavorable insofar as these force flows through the various cores are unequal, and the dimensions of the transformer of the choke coil are therefore large. A more expedient embodiment of the switching inductors results if, according to the invention, the current branches temporarily adjacent to one another at the taps of the transformer are formed from several magnetically separated inductors of a inductor system consisting of a total of more than two legs, at the midpoints of which the ends of a inductor connected to the working lines are connected are. An embodiment of the invention is illustrated in the drawing. t is the transformer with taps a, b, c. There are several switches at each tap, e.g. B. 'be a ", in parallel, by means of which lying parallel current branches connected at the same time to the same tapping points of a transformer. Are used as current paths, the choke coils t1, t2, from each of which the beginnings z. B. simultaneously to the switches a' a, ä 'of the tap point a, the ends together to the tap b with the help of switches b', b ".

Wie bei dem Schaltverfahren des Hauptpatentes werden der Reihe nach die Schalter a', ä', b', b", dann ä', b', b", c' usw. eingeschaltet, so daß sich der Reihe nach Stufenspannungen entsprechend den Punkten a" b, b, c usw. ergeben.As with the switching method of the main patent, the switches a ', ä', b ', b ", then ä', b ', b", c' etc. are switched on in sequence, so that step voltages according to the points a "b, b, c etc. result.
