   Es ist bekannt, zur Dämpfung der dritten Oberwelle an   Dreiphasentransformatoren,   deren Arbeitswicklungen in Stern geschaltet sind, eine besondere in   Dreieck geschaltete Wicklung hinzuzufügen.   



     Erfindungsgemäss   kann diese besondere Wicklung fortfallen, wenn man die leitenden Press-oder Schutzringe, die ohnehin zum Zusammenpressen der Transformatorspulen oder zu ihrem Schutz gegen steile   Spannungswellen   benötigt werden, in der Weise miteinander verbindet, dass die aus je einpr Einzelverbindung bestehenden geschlitzten Ringe zusammen in Dreieck geschaltet werden. 



   In welcher Weise das geschehen kann, ist aus der Zeichnung ersichtlich, in der a die genannten

 in Fig. 2 können Pressbolzen verwendet werden, wobei die nicht als Verbinder dienenden Bolzen gegen die Ringe elektrisch zu isolieren sind : die Schlitze e in den Ringen a müssen dann oben und unten etwas gegeneinander versetzt werden. Die Querverbindungen b können entweder durch besondere Leiter oder auch durch ohnehin vorhandene Bauteile des Transformators gebildet werden. Ferner kann man die

 Stück kann gemäss Fig. 3 in bezug auf alle drei Mittelachsen symmetrisch ausgebildet werden, indem die Schlitze c je zweier benachbarter Ringe vereinigt und in die Mittelachsen verlegt werden.

   Ja man kann sogar die Schlitze bis auf den Innendurchmesser der Ringe verbreitern, so dass für die Dreieckwicklung das Bild nach Fig. 4 entsteht ; solch ein einziger   länglicher,   alle drei Transformatorkerne umfassender. geschlossener Ring hat ebenfalls die technische Wirkung einer in Dreieck geschalteten Wicklung, indem durch ihn die dritte Oberwelle kompensiert wird. 



   Die   Dreieckwicklung kann selbstverständlich   ausser zur Dämpfung der dritten Oberwelle auch zu anderen Zwecken dienen und kann auch   bei Drosselspulen Anwendung   finden.

 EMI1.1
 



   It is known to add a special triangle-connected winding to damp the third harmonic on three-phase transformers whose working windings are connected in star.



     According to the invention, this special winding can be omitted if the conductive compression or protective rings, which are required anyway to compress the transformer coils or to protect them against steep voltage waves, are connected to one another in such a way that the slotted rings, each consisting of a single connection, are joined together in a triangle be switched.



   The way in which this can be done can be seen from the drawing, in which the mentioned
 EMI1.2
 In FIG. 2, compression bolts can be used, the bolts not serving as connectors having to be electrically insulated from the rings: the slots e in the rings a must then be slightly offset from one another at the top and bottom. The cross connections b can be formed either by special conductors or by components of the transformer that are already present. You can also use the
 EMI1.3
 According to FIG. 3, the piece can be designed symmetrically with respect to all three central axes by combining the slots c of two adjacent rings and relocating them to the central axes.

   You can even widen the slots up to the inner diameter of the rings, so that the image according to FIG. 4 is created for the triangular winding; such a single elongated one, encompassing all three transformer cores. The closed ring also has the technical effect of a winding connected in a triangle, in that it compensates for the third harmonic.



   In addition to damping the third harmonic, the delta winding can of course also be used for other purposes and can also be used in inductors.
