Description

Vorrichtung zur Vermeidung von Wirbelströmen in Eisenteilen von Transformatoren oder Drosselspulen. Die Erfindung betrifft eine Vorrichtung zur Vermeidung von Wirbelströmen in den Eisenteilen von Transformatoren oder Drosselspulen, bei der die etwa vorhandenen Streu- oder Luftfelder durch besondere lamellierte Schutzjoche geschlossen werden. Die Schutzjoche liegen in solcher Anordnung, daß die Kraftlinien an den Schmalseiten der Blechlamellen ein- bzw. austreten. Nach der Erfindung werden diese Schutzjoche, um die aus den Stirnflächen der Spulen austretenden Luft- oder Streufelder aufzufangen, derart ausgebildet, daß sie einen wesentlichen Teil der Stirnflächen der $pulen bedecken.Device to avoid eddy currents in the iron parts of transformers or reactors. The invention relates to a device for avoiding eddy currents in the iron parts of transformers or reactors, in which the possibly existing Stray or air fields can be closed by special laminated protective yokes. The protective yokes are arranged in such a way that the lines of force on the narrow sides the sheet metal lamellas enter or exit. According to the invention, these protective yokes, to catch the air or stray fields emerging from the end faces of the coils, designed in such a way that they form a substantial part of the faces of the pulleys cover.

In der Zeichnung ist ein Ausführungsbeispiel in Abb. i in Seitenansicht mit aufgeschnittenen Spulen und in Abb. 2@ im Schnitt A-B dargestellt. Es bedeutet I i die Spulen, 12 die Kerne und 13 die Joche einer Drosselspule. Nach der Erfindung sind Schutzjoche 1q. zur Rückführung der Luft-oder Streukraftlinien vorgesehen und derart ausgebildet"daß sie den freien Teil der Stirnflächen der Spulen im wesentlichen bedecken.In the drawing, an embodiment is shown in Fig. I in a side view with cut coils and in Fig. 2 @ in section AB. It means I i the coils, 12 the cores and 13 the yokes of a choke coil. According to the invention, protective yokes 1q. provided for the return of the air or stray force lines and designed in such a way that they essentially cover the free part of the end faces of the coils.

Die Ausführung hat den Vorteil, daß die Streukraftlinierr möglichst zahlreich in die Schutzjoche eintreten, und zwar im wesentlichen an der Schmalseite der Blechlamellen.The design has the advantage that the scattering force lines as possible enter the protective yokes numerous, essentially on the narrow side of the sheet metal lamellas.

Die Form der Schutzjoche kann den jeweiligen Verhältnissen angepaßt werden. Die Schutzjoche können frei neben dein Hauptjoch 13 liegen oder an dieses angelehnt sein.The shape of the protective yokes can be adapted to the respective conditions will. The protective yokes can lie freely next to your main yoke 13 or on this be ajar.
