Description

Einphasentransformator mit parallel geschalteten, vollkommen gleich ausgeführten, auf zwei Schenkel verteilten, angezapften Wicklungen Es ist bekannt, bei höheren Strömen die Wicklungen von Transformatoren mit Rücksicht auf die Streuung und Stromverdrängung aus parallelen Zweigen zusammenzusetzen. Bei Einphaszntransformatoren ist es insbesondere bei Parallelschaltung von mit Anzapfungen versehenen Wicklungen üblich, diese, wie in Abb. i dargestellt, auf zwei Schenkel zu verteilen und den Wicklungen jedes Schenkels einen anderen Wickelsinn zu geben. Sind beispielsweise al und a2 die beiden Schenkel eines Einphasentran;sformators, so wird die Wicklung b1 rechts um den Schenkel a, und die Wicklung b2 links um den Schenkel a2 herum gewickelt und beide sowohl mit ihren nebeneinanderliegenden Enden f 1, f 2 als auch mit ihren Anzapfungen cl, c2 bis e1, e2 parallel. geschaltet. Eine derartige Anordnung weist aber verschiedene Nachteile auf. So leidet durch die Verschiedenheit des Wicklungssinnes der Wicklungen die Einheitlichkeit der Fabrikation. Bei gleichzeitiger Anfertigung mehrerer Transformatoren können ferner durch die Verschiedenheit der Wicklungen leicht Verwechselungen vorkommen. Schließlich müssen bei der Bestellurig von Reservewicklungen diese für beide-Schenkel in verschiedener Ausführung geliefert werden. Würde man anderseits die beiden Spulen mit gleichem Wickelsinn ausführen, so kann man die beiden Wicklungen immer nur bei einer Anzapfung parallel schalten, z. B. wie in Abb. 2 dargestellt, an den mittleren Anzapfungendl und d2.Single-phase transformer with parallel connected, perfectly the same executed, tapped windings distributed over two legs It is known in the case of higher currents, the windings of transformers, taking into account the scatter and assemble current displacement from parallel branches. With single-phase transformers it is particularly the case when windings provided with taps are connected in parallel It is customary to distribute these over two legs, as shown in Fig. i, and the To give each leg a different winding direction. Are for example al and a2 the two legs of a single-phase transformer, so the winding b1 to the right around the leg a, and the winding b2 to the left around the leg a2 wound and both with their adjacent ends f 1, f 2 as well with their taps cl, c2 to e1, e2 parallel. switched. Such an arrangement but has various disadvantages. So suffers from the difference in the sense of winding of the windings the uniformity of manufacture. With simultaneous production multiple transformers can also be achieved by the difference in the windings mix-ups can easily occur. Finally, when ordering reserve windings these are supplied in different designs for both legs. You would on the other hand, run the two coils with the same winding direction, so you can Always connect both windings in parallel with one tap, e.g. B. as in Fig. 2 shown at the middle taps endl and d2.

Diese Nachteile fallen fort, wenn man erfindungsgemäß die mit Anzapfungen verseheneg Wicklungen für beide Schenkel zwar gleich ausführt, jedoch umgekehrt auf die Schenkel aufsteckt und ihre Enden sowie die gleich weit von diesen liegenden Anzapfungen kreuzweise miteinander verbindet.These disadvantages are eliminated if, according to the invention, the one with taps provided windings are the same for both legs, but vice versa slipped onto the legs and their ends as well as those lying equidistant from them Taps crosswise connects with each other.

In Abb.3, welche ein Ausführungsbeispiel der Erfindung wiedergibt, sind Mund b2 die parallel geschalteten, gleichsinnig gewikkelten und umgekehrt auf die Schenkel aufgesteckten Wicklungen. Bei bl liegen die An-. zapfungen cl, dl, el unten, bei der Wicklung b2 hingegen die Anzapfungen c2, d2, e2 oben. Die kreuzweise ausgeführten Verbindungen der Wicklungsenden und Anzapfungen werden an die Klemmen c, d, e, f angeschlossen.In FIG. 3, which shows an exemplary embodiment of the invention, mouth b2 are the windings connected in parallel, wound in the same direction and reversely attached to the legs. At bl are the areas. taps cl, dl, el below, in the case of winding b2, however, the taps c2, d2, e2 above. The cross connections of the winding ends and taps are connected to terminals c, d, e, f .

Die Erfindung kann sinngemäß auch bei Wicklungen angewandt werden, bei welchen die Anzapfungen in den mittleren Teilen der Wicklungsanordnungen liegen; wenn also beispielsweise in Abb.3 unterhalb der Wicklung b1 und oberhalb der Wicklung b2 weitere Wicklungsteile b3 und b,1 angeordnet sind, die - wie in Abb. s urgestellt - mit ihren Enden hl, h2 bzw. g1, g2 unter sich kreuzweise parallel geschaltet und an je einem ihrer Wicklungsenden g, und g2 wahlweise mit den Anzapfungen c1, d1, e1 bzw. C2, d2, e2 der übrigen Wicklungen verbunden werden.The invention can analogously also be applied to windings, in which the taps are in the middle parts of the winding arrangements; if for example in Fig.3 below the winding b1 and above the winding b2 further winding parts b3 and b, 1 are arranged, which - as shown in Fig. s - With their ends hl, h2 or g1, g2 connected crosswise in parallel and at one of its winding ends g, and g2, optionally with the taps c1, d1, e1 or C2, d2, e2 of the remaining windings are connected.
