Description

Die Erfindung betrifft eine weitere Ausbildung der Schaltung des Hauptpatents ' 404602. Abb. ι und 2 stellen die neue Schaltung schematisch dar. Wie Abb. 1 zeigt, sind die Schaltkontakte so angeordnet, daß einmalj wie im Hauptpatent, 1 mit I, 2 mit II usw., aber auch! I mit 2, II mit 3 usw. verbunden werden können. Außerdem kann aber auch II mit 1, III mit 2 usw. verbunden werden. Es entstehen so mit fünf Kontakten 13 Regelstufen, bestehend aus drei Leerspannungsstufen, wobei zwei dieser Leerspannuingen in je vier Stufen, die eine, wie in dem Hauptpatent, in fünf Stufen in der Streuung regelbar sind. Es wird so also mit wenig Anzapfungen eine weitgehende Regelbarkeit der Lastspannung erreicht.The invention relates to a further embodiment of the circuit of the main patent '404602. Fig. Ι and 2 represent the new circuit schematically. As Fig. 1 shows, are the switching contacts arranged so that once as in the main patent, 1 with I, 2 with II etc., but also! I connected to 2, II to 3, and so on can be. In addition, II can be connected to 1, III to 2, and so on. This creates 13 control levels with five contacts, consisting of three no-load voltage levels, two of these idle spans in each four levels, one, as in the main patent, adjustable in five levels in the spread are. This means that the load voltage can be largely controlled with only a few taps achieved.

Diese Anpassung kann noch weiter dadurch erhöht werden, daß nach Abb. 2 die einzelnenThis adaptation can be further increased by the fact that according to Fig. 2 the individual

ao Zuschaltspulen der auf dem Neberikern liegenden Wicklung von den Stufenspulen der Hauptkernwicklung verschiedene Windungszahlen erhalten. (In Abb. 2 bedeuten die eingeschriebenen Zahlen beispielsweise Windungszahlen.) ao connection coils of the winding lying on the Neberikern from the step coils of the Main core winding received different numbers of turns. (In Fig. 2, the inscribed Numbers, for example, number of turns.)

Es läßt sich also mit der neuen Schaltung eine Anpassung der Sekundär spannung sowohl unter Last als auch leer erreichen, die bei den bisher bekannten Anordnungen auch mit vielen Anzapfungen nicht in gleicher Weise erreichbar war.So it can be with the new circuit an adaptation of the secondary voltage both under load as well as empty, with the previously known arrangements also with many taps could not be reached in the same way.
