Description
Wicklungen von Transformatoren, Drosselspulen und anderen elektrischen Apparaten für hohe Ströme bestehen gewöhnlich aus einer oder mehreren Spulen mit einer größeren Anzahl parallel geschalteter und in der Regel isolierter Leiter, mit denen zu den Durchführungen gehende Ableitungen durch Löten oder durch Bolzen verbunden sind. Auf diese Weise erhält man zwischen der Wicklung und den Durchführungen Stellen, die einmal große Übergangswiderstände haben und sich demgemäß stark erwärmen können und zum andern viel Montagearbeit und viel Raum bedingen.Windings of transformers, reactors and other electrical Apparatus for high currents usually consist of one or more coils with a larger number of parallel-connected and usually insulated conductors, with those leading to the bushings by soldering or by bolts are connected. This way you get between the winding and the bushings Places that once have high contact resistance and accordingly heat up strongly and on the other hand require a lot of assembly work and a lot of space.
Die Erfindung beseitigt diese L`belstände dank einer Konstruktion, die gleichzeitig eine einfachere Isolierung und bessere Kühlmöglichkeiten ergibt. Die Wicklung ist eine sogenannte Hochkantwicklung, die aus einer oder mehreren, durch Isolierzw ischenlagen getrennten Windungen bestehen kann. Erfindungsgemäß ist wenigstens das eine Ende der Wicklung in Längsrichtung in Streifen unterteilt, die senkrecht zu dieser Richtung in Axialrichtung umgebogen, sind.The invention eliminates these l 'debris thanks to a construction which at the same time results in simpler insulation and better cooling options. The winding is a so-called upright winding, which consists of one or more, windings separated by insulating layers can exist. According to the invention at least one end of the winding is divided into strips in the longitudinal direction, which are bent in the axial direction perpendicular to this direction.
Eine Ausführungsform der Erfindung ist in der Zeichnung dargestellt.An embodiment of the invention is shown in the drawing.
Fig. i zeigt ein Spulenblech vor dem Wickeln; Fig.2 ist ein Querschnitt durch die Wicklung, und Fig.3 und d. zeigen Längsschnitte nach den Linien A-A bzw. B-B in Fig. 2.Fig. I shows a coil sheet before winding; Fig.2 is a cross section through the winding, and Fig.3 and d. show longitudinal sections along the lines A-A and B-B in Fig. 2.
Das Spulenblech i, von dem nur die beiden Enden in Fig. i dargestellt sind, ist, wie ersichtlich, an diesen Enden in drei Streifen 2, 3 und .4 und 5, 6 und 7 aufgeschnitten, die nach dem Wickelvorgang längs den schrägen strichpunktierten Linien rechtwinklig zu der Wicklungsrichtung des Bleches aufgebogen werden, wie aus Fig. 2, 3 und .4 hervorgeht. Das Blechmaterial ist vorzugsweise ziemlich dünn, um die Zusatzverluste in erträglichen Grenzen zu halten. Die Zuführungen lassen sich daher ziemlich leicht in Richtung der Hochkante biegen und können ohne Stoßverbindungen zu den Durchführungen geführt werden. Sie bilden auch eine so nachgiebige Verbindung, wie sie bei den bekannten Ausführungsformen mit aus dickeren Schienen bestehenden Zuführungsleitern erst mit komplizierten Mitteln geschaffen werden muß. Die Windungen werden durch Einlegen eines geeigneten Isoliermaterials 8, z. B. Preßspan, von ungefähr gleicher Breite- wie das Windungsblech voneinander isoliert oder durch Einsetzen von Isolierrippen, wodurch eine wirksame Kühlung erzielt wird. Die Isolierung zwischen den Windungen kann auch aus Isolierstoff, z. B. Preßspan, mit axialer Wellung bestehen, so daß eine Vielzahl axialer Kühlkanäle entsteht.The coil sheet i, of which only the two ends are shown in Fig. I is, as can be seen, at these ends in three strips 2, 3 and 4 and 5, 6 and 7 cut open, the dash-dotted line after the winding process along the oblique Lines at right angles to the winding direction of the sheet are bent open, like from Fig. 2, 3 and .4 emerges. The sheet material is preferably quite thin, in order to keep the additional losses within tolerable limits. Leave the feedings therefore bend fairly easily in the direction of the upright and can without butt joints to the bushings. They also make such a resilient connection as in the known embodiments with existing thick rails Feed ladders must be created with complicated means. The turns are by inserting a suitable insulating material 8, z. B. Pressboard, by approximately same width as the winding sheet isolated from each other or by inserting of insulating ribs, whereby an effective cooling is achieved. The isolation between the turns can also be made of insulating material, e.g. B. Pressboard, with axial corrugation, so that a large number of axial cooling channels are created.
Wenn die Wicklung mit zwei oder mehreren konzentrisch angeordneten Spulen ausgeführt wird, werden die Ableitungen zweckmäßig-erweise auf den Umkreis verteilt.When the winding with two or more concentrically arranged Coils is carried out, the derivatives are expediently on the circumference distributed.
Um den Zusammenhalt der Windungen zu erhöhen, ist es besonders bei in axialer Richtung sich erstreckenden Spulen zweckmäßig, einen oder mehrere mit durchgehender Isolation versehene Niete oder Bolzen zu verwenden.In order to increase the cohesion of the coils, it is especially useful for expediently extending in the axial direction coils, one or more with rivets or bolts provided with continuous insulation.
