Description

Spannungsregelnder Transformator mit zwei relativ zum Kern verschiebbaren Jochteilen und in Nuten eingebetteten Induktionswicklungen Bei einem spannungsregelnden Transformator mit zwei relativ zum Kern verschiebbaren Jochteilen und in Nuten eingebetteten Induktionswicklungen, der unter dem Namen »Schubtransformator« sich in der Technik eingebürgert hat, werden die Nuten sowohl des Kernes als auch der Joche symmetrisch zueinander angeordnet, so also, daß man immer gerade Wicklungen erhält. Die Regelkurve eines derartig stufenlos regelnden Transformators nähert sich nur entsprechend der Nutenzähl der idealen geradlinig ansteigenden Spannungskurve.Voltage regulating transformer with two displaceable relative to the core Yoke parts and induction windings embedded in grooves Transformer with two yoke parts which can be moved relative to the core and which are embedded in grooves Induction windings, which is known in the art under the name »shear transformer« has become naturalized, the grooves of both the core and the yokes become symmetrical arranged to each other, so that you always get straight windings. The control curve such a continuously variable transformer only approximates accordingly Groove count of the ideal linearly increasing voltage curve.

Die Erfindung beabsichtigt, bei einem derartigen spannungsregelnden Transformator die Spannungskurve zu verbessern, und zwar möglichst unter Beibehaltung der gleichen Anzahl von Nuten> Erfindungsgemäß erfolgt dies dadurch, daß die Nuten der Joche axial gegeneinander versetzt bzw. verschöben sind oder die zu beiden Seiten des Kernes liegenden Nuten in dieser Weise angeordnet werden. Durch diese Maßnahme wird ein Aufeinanderwirken der Wicklungen auf einen größeren Bereich und damit die bessere Spannungsregelcharakteristik erzielt.The invention is intended in such a voltage regulating Transformer to improve the voltage curve, preferably while maintaining it the same number of grooves> According to the invention, this is done in that the grooves of the yokes are axially offset or shifted from one another or on both sides of the core lying grooves are arranged in this way. By this measure an interaction of the windings on a larger area and thus the better voltage regulation characteristics achieved.

In den Abbildungen sind Ausführungsbeispiele gemäß der Erfindung dargestellt: Nach Abb. i sind die Nuten ix mit den darin befindlichen Wicklungen i2 der beiden Joche 13, 1q. gegeneinander versetzt, so daß die außerhalb der Joche liegenden Wicklungsteile (Wickelköpfe) schräg verlaufen, wie dies gestrichelt angedeutet ist. Die Nuten in dem Kernteil 15 sind bei diesem Ausführungsbeispiel noch symmetrisch zur Kernachse. Es können natürlich auch die oberhalb und unterhalb der Wicklungen. 12 gezeichneten Hauptwicklungen in gegeneinander versetzte Jochnuten untergebracht werden.In the figures, exemplary embodiments according to the invention are shown: According to Fig. I, the slots ix with the windings i2 of the two yokes 13, 1q located therein. offset from one another, so that the winding parts (winding heads) lying outside the yokes run obliquely, as indicated by dashed lines. In this exemplary embodiment, the grooves in the core part 15 are still symmetrical to the core axis. Of course, the above and below the windings can also be used. 12 drawn main windings are housed in mutually offset yoke slots.

# Es ist jedoch auch möglich, gemäß Abb. 2 die Nuten 16 zu beiden Seiten des Kernes 15 gegeneinander zu versetzen und diesen dargestellten Kern in Verbindung mit den beiden Jochen 13, 1q. nach Abb. x zu bringen, so daß sowohl Kern als auch Joche versetzte Nuten besitzen. Auch läßt sich der Kern nach Abb. 2 mit Jochen zusammensetzen, die nicht axial gegeneinander versetzte Nuten besitzen.# However, it is also possible, as shown in Fig. 2, the grooves 16 to both To offset sides of the core 15 from one another and this core shown in Connection with the two yokes 13, 1q. to bring to Fig. x, so that both core as well as yokes have staggered grooves. The core according to Fig. 2 can also be used Assemble yokes that do not have axially offset grooves.

Eine andere Möglichkeit zeigt Abb.3, nach der die Nuten 16 des Kernteiles 15, die die einzelnen Eisenbleche durchlaufen, in einem gemeinsamen Winkel zur Schichtrichtung verlaufen. Die Winkel können naturgemäß auch verschieden sein, insbesondere für die oberste und unterste Nutenzahl. Die Nuten in den Jochen 13, 14 lassen sich- naturgemäß auch so ausbilden, wie dies in Abb. 2 und 3 für den Kernteil 15 beschrieben ist.Another possibility is shown in Fig.3, according to which the grooves 16 of the core part 15, which pass through the individual iron sheets, at a common angle to the layer direction get lost. The angles can of course also be different, in particular for the top and bottom number of slots. The grooves in the yokes 13, 14 can be naturally also train as described in FIGS. 2 and 3 for the core part 15 is.
