Description

Es sind Transformatoren mit gewickeltem Joch und geschichteten Schenkeln bekannt. Diese Transformatoren werden hergestellt, indem beim Wickeln des Joches zwischen das bandförmige Blechmaterial an den für die Schenkel vorgesehenen Stellen in jeder Blechlage Abstandsstücke eingelegt werden. Diese dadurch erhaltene Spirale wird zusammengepreßt und durch einen Glühprozeß spannungsfrei gemacht. Danach werden die einzelnen Abstandsstücke durch Einführen der Schenkelbleche herausgestoßen.They are transformers with a wound yoke and layered legs known. These transformers are made by winding the yoke between the strip-shaped sheet metal material at the points provided for the legs Spacers are inserted in each sheet metal layer. This spiral thus obtained is pressed together and made stress-free by an annealing process. After that will be the individual spacers pushed out by inserting the leg plates.

Diese Art der Verbindung von Joch und Schenkelblech ist jedoch äußerst zeitraubend und eignet sich nur für die manuelle Herstellung derartiger Kerne. Ein gleichzeitiges Herausstoßen der gesamten Abstandsstücke durch das Schenkelpaket ist wegen der nicht festzulegenden Abstände der einzelnen Jochbänder bzw. Schenkelbleche technisch unmöglich. Die Mechanisierung ist bei dieser Herstellungsart, wenn überhaupt, nur mit komplizierten Mitteln durchführbar. Dadurch wird der Kern, der in magnetischer sowie mechanischer Hinsicht gegenüber den üblichen Kernformen wesentliche Vorteile hat, für eine Massenfertigung nicht geeignet.However, this type of connection between the yoke and the leg plate is extreme time consuming and only suitable for the manual production of such cores. A simultaneous pushing out of the entire spacer by the leg package is because of the non-definable distances between the individual yoke strips or leg plates technically impossible. In this type of production, mechanization is, if at all, only feasible with complicated means. This makes the core, which is in magnetic as well as mechanical advantages over the usual core shapes has, not suitable for mass production.

Diese Nachteile werden bei dem Verfahren nach der Erfindung zur Herstellung mehrschenkliger Magnetkerne für Transformatoren und Drosselspulen mit aus durchlaufendem Blechband gewickeltem Joch und darin eingeschichteten Schenkeln dadurch beseitigt, daß erfindungsgemäß die einzelnen Schenkelbleche während des Wickelvorganges des Joches an den für die Schenkel jeweils vorgesehenen Stellen unmittelbar eingelegt werden.These disadvantages become apparent in the method of manufacture according to the invention multi-limbed magnetic cores for transformers and reactors with a continuous Yoke wrapped in sheet metal band and legs layered in it eliminated, that according to the invention the individual leg plates during the winding process of the Yoke inserted directly into the places provided for the legs will.

Durch die Erfindung wird erreicht, daß nicht erst, nachdem das Joch gewickelt ist, die Schenkelbleche eingeschichtet werden müssen, sondern bereits beim Wickeln des Joches an den für die Schenkel vorgesehenen Stellen die Schenkelbleche bereits mit eingeschichtet sind. Dieser Arbeitsgang ist verhältnismäßig leicht zu mechanisieren; das zeitraubende Herausstoßen der einzelnen Abstandsstücke durch die einzelnen Schenkelbleche entfällt damit.The invention achieves that not only after the yoke is wound, the leg plates must be layered, but already when winding the yoke at the points provided for the legs, the leg plates are already layered. This operation is relatively easy too mechanize; the time-consuming pushing out of the individual spacers the individual leg plates are thus omitted.

Auf diese Weise werden die Vorteile eines gewikkelten Magnetkernes in elektrischer Hinsicht, nämlich die Verminderung der Leerlaufverluste und des Leerlaufstromes, mit den Vorteilen eines üblichen Magnetkerns in mechanischer Hinsicht, nämlich einfache Herstellung, leichte Montage und Demontage der Wicklung; in zweckmäßiger Weise kombiniert.In this way, the advantages of a wound magnetic core in electrical terms, namely the reduction of no-load losses and the No-load current, with the advantages of a conventional magnetic core in mechanical terms, namely simple manufacture, easy assembly and disassembly of the winding; in more expedient Way combined.
