In the case of smaller three-phase transformers, one puts the switching device usually to the

Für diese beiden verschiedenen Ausführungsformen waren bisher verschiedene Umschaltvorrichtungen erforderlich, da einmalDifferent switching devices have hitherto been used for these two different embodiments required because once

Die Erfindung ermöglicht es, für beide 'Schaltarten die gleiche Umschaltvorrichtung zu verwenden, in der Weise, daß die für die Schaltart nach Abb. 2 erforderlichen 3 Umschalter so eingerichtet werden, daß sie auch für die Schaltart nach Abb. 1 angewendet werden können. In Abb. 3 ist) ein solcher Umschalter dargestellt.The invention makes it possible to use the same switching device for both types of switching to be used in such a way that the 3 changeover switches required for the type of switching according to Fig. 2 be set up in such a way that they are also used for the switching type according to Fig. 1 can be. Such a switch is shown in Fig. 3.
Derselbe -besteht aus einer Anzahl im Kreise angeordneter Kontakte I I, II II, III III, über die ein Kontakt r" gleitet, der an einen um die Achse α drehbaren Hebel h sitzt. Die Anordnung der Kontakte geht aus der eine Abwicklung zeigenden Abb. 4 hervor. Die Mittellinie des festen Kontaktes d liegt parallel der den festen Kontakten e und f gemeinsamen Mittellinie; dabei ist die Kontaktfläche vond annähernd so groß, wie die Summe der beiden Kontaktflächen vone und/. Zur Erlangung eines sicheren Kontaktes mit den drei Einzelkontakten ist das bewegliche Kontaktstück! in zwei elektrisch verbundene aber mechanisch gegeneinander federnde Hälften rx und r% unterteilt. Führt man r als Rolle aus, so ist es zweckmäßig, die Abstände der festen Kontakte in der Bewegungsrichtung der Rolle verschieden zu machen, wie aus der Abb. 4 zu erkennen ist. Die Rolle findet dann in den großen Lücken eine Arretierung, während sie beim Weiterschalten über die kleinen Lücken glatt hinweggleitet. It consists of a number of contacts II, II II, III III arranged in a circle, over which a contact r "slides, which sits on a lever h rotatable about the axis α . The arrangement of the contacts is shown in the Fig. 4. The center line of the fixed contact d lies parallel to the center line common to the fixed contacts e and f ; the contact area of d is approximately as large as the sum of the two contact areas of e and / the movable contact piece! is divided into two electrically connected but mechanically mutually resilient halves r x and r % . If r is designed as a roller, it is useful to make the distances between the fixed contacts different in the direction of movement of the roller, as shown in Fig 4. The roller then finds a lock in the large gaps, while it slides smoothly over the small gaps when switching on.
Abb. S und 6 zeigen, in weicher Weise der Umschalter an die Wicklungen der Transformatoren anzuschließen ist, um ihn für beide Schaltarten zu verwenden. Dadurch, daß in der Schaltung nach Abb. 6 die beidenFig. S and 6 show in a soft way the changeover switch on the windings of the transformers must be connected in order to use it for both types of switching. The fact that in the circuit according to Fig. 6 the two

S verwendbar. split contacts e and / or reconnected to one, in this arrangement the apparatus can be used for a current twice as high as in the circuit according to Fig. S.
