Description

Die Erfindung betrifft ein Verfahren zur Aufbringung einer Wicklung auf einen mehrschenkeligen Kern, wobei die Wicklung aus mehreren Teilwicklungen besteht, von denen mindestens eine eine Einzelwicklung ist, die einen einzelnen der Schenkel umgibt, und eine andere eine umfassende Wicklung ist, die eine Schenkelgruppe bestehend aus mehreren der Schenkel des Kernes umgibt. Ferner betrifft die Erfindung einen nach diesem Verfahren hergestellten Kern mit Wicklung.The invention relates to a method for applying a winding on a multi-legged core, the winding consisting of several There are partial windings, at least one of which is a single winding that surrounds one of the legs and another is a comprehensive winding that consists of a leg group surrounding several of the legs of the core. The invention further relates to a winding core produced by this method.

Bisher wurde für die Herstellung von Transformatoren mit mehrschenkeligen Kernen, die sowohl Wicklungen enthalten, die einzelne Schenkel umgeben, als auch Wicklungen enthalten, die über sehrere Schenkel reichen, eine externe Bewicklung eines Spulenkörpers oder eines Spulenkäfiges vorgenommen, der dann über die Schenkelgruppe geschoben wurde und nach der Verbindung der Schenkel mit Hilfe der Joche gegenüber den Einzelwicklungen auf den Schenkeln verkeilt wurde.So far, for the manufacture of transformers with multi-legged Cores that contain both windings, the single leg surrounded, as well as included windings that have more legs enough, an external winding of a bobbin or one Made coil cage, which then pushed over the leg group and after connecting the legs with the help of the yokes was wedged against the individual windings on the legs.

Ziel der vorliegenden Erfindung ist es, statt diesem in der Montage aufwendigen Verfahren ein einfaches, rasches und kostengünstiges Verfahren zur Bewicklung solcher Transformatoren zu finden. Der dadurch hergestellte Transformator soll kompakt sein und dennoch soll eine entsprechende Wärmeabfuhr gewährleistet sein.The aim of the present invention is instead of this in the assembly complex process a simple, quick and inexpensive Finding methods for winding such transformers. The result manufactured transformer should be compact and yet should appropriate heat dissipation can be guaranteed.

Die genannte Aufgabe wird dadurch gelöst, daß bei dem eingangs genannten Verfahren zuerst die Einzelwicklung(en) auf dem (den) einzelnen Schenkel(n) gewickelt wird (werden), daß dann die Schenkelgruppe durch Verbinden der zugehörigen Schenkel zusammengestellt und umwickelt wird und daß schließlich gegebenfalls vorgesehene nicht zur Schenkelgruppe gehörende bewickelte oder unbewickelte Schenkel oder weitere Schenkelgruppen angefügt und fixiert werden. Die Schenkelgruppe dient also als Träger für die mehrere Schenkel umschliessende Wicklung. Dadurch ist kein Spulenkörper oder Spulenkäfig mehr erforderlich und es entfällt das aufwendige Verkeilen der mehrere Schenkel umschliessenden Wicklung gegenüber den Einzelwicklungen.The above-mentioned object is achieved in that the above-mentioned First process the single winding (s) on the individual (s) Leg (s) is (are) wrapped that then the leg group assembled by connecting the associated legs and is wrapped and that eventually eventually not provided wrapped or unwrapped thighs belonging to the thigh group or other groups of legs are attached and fixed. The thigh group thus serves as a carrier for the several legs enclosing Winding. As a result, there is no longer a coil former or coil cage required and the time-consuming wedging of several is eliminated Winding surrounding the legs compared to the individual windings.

Vorzugsweise werden vor dem Umwickeln der Schenkelgruppe an deren Außenkanten Eckteile angeordnet, die parallel zur Wickelachse ausgerichtet sind. Ebenso können an den Außenflächen Distanzstücke vorgesehen sein, die ebenfalls parallel zur Wickelachse ausgerichtet sind. Diese Eckteile und Distanzstücke tragen die mehrere Schenkel umschließende Wicklung und der zwischen den Einzelwicklungen und der mehrere Schenkel umschließenden Wicklung entstehende Luftspalt sichert eine gute Wärmeabfuhr.Preferably, before wrapping around the leg group Outside edges of corner parts arranged parallel to the winding axis are. Spacers can also be provided on the outer surfaces be also aligned parallel to the winding axis are. These corner pieces and spacers carry the several legs enclosing winding and that between the individual windings and the air gap that arises from several legs surrounding the winding good heat dissipation.

Das Verbinden der Schenkel der Schenkelgruppe erfolgt vorzugsweise durch Befestigung der Joche an den Schenkeln der Schenkelgruppe. Die dabei vorzugsweise verwendete Spannkonstruktion kann gleichzeitig zur Fixierung der Eckteile und der Distanzstücke dienen.The legs of the leg group are preferably connected by attaching the yokes to the legs of the leg group. The preferably used tensioning structure can simultaneously serve to fix the corner parts and the spacers.

Sind die Schenkel der Schenkelgruppe durch die Joche des Kernes verbunden, so werden die gegebenenfalls vorhandenen bewickelten oder unbewickelten Schenkel bzw. weiteren Schenkelgruppen, die noch angefügt werden sollen, in die Joche eingeschichtet und fixiert.If the legs of the leg group are connected by the yokes of the core, so the possibly existing or wound unwrapped thighs or other thigh groups that are still attached should be layered and fixed in the yokes.

Die vorliegende Erfindung soll nun noch anhand eines in den beiliegenden Zeichnungen dargestellten Ausführungsbeispieles beschrieben werden. Dabei zeigt die Fig. 1 schematisch den möglichen Aufbau eines Kernes mit Einzelwicklungen und einer mehrere Schenkel umfassenden Wicklung; die Fig. 2 zeigt den Schnitt gemäß der Linie II-II in Fig. 1 und die Fig. 3 und 4 zeigen die Lage der Kernblechstreifen in zwei verschiedenen Schichten des Kernes. The present invention is now intended to be based on one of the accompanying drawings Drawings described embodiment described become. 1 shows schematically the possible structure of a Core with single windings and a multi-leg Winding; Fig. 2 shows the section along the line II-II in Fig. 1 and Figs. 3 and 4 show the location of the core sheet strips in two different layers of the core.

Wie man sieht trägt der Schenkel 2 eine Einzelwicklung 11, die z.B. die Primärwicklung eines Transformators sein kann, dessen Sekundärwicklung 12 die Schenkel 2, 3 und 4 umgibt. Die den Schenkel 3 umgebende Wicklung 13 und die den Schenkel 4 umgebende Wicklung 14 stellen eine Gleichstromsteuerwicklung dar. Die Wicklung 16 auf Schenkel 3 und die Wicklung 15 auf Schenkel 4 kompensieren die Unsymmetrie des Kernes. Um nunmehr diese als Beispiel dienende Anordnung herzustellen, wird der Schenkel 2 mit der Primärwicklung 11 versehen und die Schenkel 3 und 4 mit der Gleichstromwicklung 13, 14 und der Kompensationswicklung 15, 16. Dann werden die Schenkel 2, 3 und 4 durch die Joche 6 und 7 miteinander verbunden und z.B. mittels einer Spannkonstruktion fixiert. Die Schenkel 2, 3 und 4 sind somit zur Schenkelgruppe 5 zusammengefaßt. An der Außenfläche der Schenkelgruppe 5 werden in den Eckbereichen die Eckteile 8 und an den großen Flächen die Distanzstücke 9 vorgesehen, und zwar so, daß sie parallel zur Wickelachae ausgerichtet sind. Die Eckteile 8 und die Distanzstücke 9 können an der Spannkonstruktion befestigt werden. Die so gebildete Einheit kann nunmehr mittels einer Wickelvorrichtung an der Wickelmaschine angebracht werden und mit der Sekundärwicklung 12 bewickelt werden. Die Eckteile 8 und die Distanzstücke 9 tragen diese Wicklung 12 und bilden zwischen den Einzelwicklungen 11, 13, 14, 15, 16 und der mehrere Schenkel umschließenden Wicklung 12 einen Luftspalt, der eine gute Wärmeabfuhr garantiert.As can be seen, the leg 2 carries a single winding 11 which e.g. can be the primary winding of a transformer, its secondary winding 12 surrounds the legs 2, 3 and 4. The surrounding the leg 3 Set winding 13 and the winding 14 surrounding leg 4 a DC control winding. The winding 16 on leg 3 and the winding 15 on leg 4 compensate for the asymmetry of the core. Now to make this example arrangement, the leg 2 is provided with the primary winding 11 and the legs 3 and 4 with the DC winding 13, 14 and the compensation winding 15, 16. Then the legs 2, 3 and 4 are through yokes 6 and 7 joined together and e.g. by means of a Fixing structure fixed. The legs 2, 3 and 4 are thus for Leg group 5 summarized. On the outer surface of the leg group 5 in the corner areas, the corner parts 8 and on the large ones Surface the spacers 9 provided, so that they are parallel are aligned to the Wickelachae. The corner pieces 8 and the spacers 9 can be attached to the tensioning structure. The unit thus formed can now be attached by means of a winding device be attached to the winding machine and with the secondary winding 12 be wound. The corner parts 8 and the spacers 9 support them Winding 12 and form between the individual windings 11, 13, 14, 15, 16 and the winding 12 enclosing several legs one Air gap that guarantees good heat dissipation.

Die Bleche des Kernes können abwechselnd die in Fig. 3 und Fig. 4 dargestellten Lagen haben. Die derart ausgestalteten Schichten werden abwechselnd aneinandergereiht.The sheets of the core can alternately be those in FIGS. 3 and 4 positions shown. The layers designed in this way are alternately strung together.
