Description
Transformator mit einer in Stufen unterteilten regelbaren Wicklung, deren einzelne Wicklungsstufen sich jeweils nur über einen Teil der Magnetschenkellänge erstrecken, und einer Wicklung zum Ausgleich der Amperewindungsverteilung, die in eine der Stufenzahl der regelbaren Wicklung entsprechende Anzahl paralleler Stromzweige aufgeteilt ist Gegenstand des Hauptpatents ist ein Transformator mit einer in Stufen unterteilten regelbaren Wicklung und einer Ausgleichwicklung, die in .eine der Stufenzahl der regelbaren Wicklung entsprechende Anzahl paralleler Stromzweige unterteilt ist. Jeder Teil der Ausgleichwicklung ist wenigstens annähernd symmetrisch zu beiden Seiten der Mittelebene einer Wicklungsstufe der .regelbaren Wicklung angeordnet. Bei dieser Anordnung ergibt sich eine enge magnetische Verkettung der beiden Wicklungsarten, die einen zuverlässigen Ausgleich in der Verteilung der Amperewindungen beim Abschalten einzelner Wicklungsstufen sichert.Transformer with an adjustable winding divided into steps, the individual winding stages of which are each only part of the length of the magnet leg extend, and a winding to compensate for the ampere turn distribution, which in a number of parallel current branches corresponding to the number of stages in the adjustable winding is the subject of the main patent is a transformer with one in stages subdivided adjustable winding and a compensating winding, which is divided into one of the number of stages the number of parallel current branches corresponding to the controllable winding is subdivided. Each part of the equalizing winding is at least approximately symmetrical to both Sides of the center plane of a winding stage of the adjustable winding. This arrangement results in a close magnetic link between the two types of winding, a reliable balance in the distribution of the ampere turns when switching off individual winding stages.
Nach der Erfindung wird die magnetische Verkettung der beiden Wicklungsarten noch dadurch verbessert, daß die Leiter der regelbaren Wicklung und der Ausgleichwicklung wenigstens annähernd gleichmäßig über den Querschnitt der einzelnen Spulen verteilt werden. Eine besonders einfache Herstellung und Montage der Wicklung wird dadurch ermöglicht, daß man beide Wicklungen bifilar, bei Scheibenspulen z. B. als doppelgängige Spirale, wickelt.According to the invention, the magnetic concatenation of the two types of winding further improved by the fact that the conductors of the adjustable winding and the equalizing winding at least approximately evenly distributed over the cross section of the individual coils will. This makes it particularly easy to manufacture and assemble the winding enables both windings to be bifilar; B. as double Spiral, wraps.
Ein Ausführungsbeispiel des Erfindungsgegenstandes ist im Schema in der Zeichnung dargestellt.An embodiment of the subject matter of the invention is shown in the scheme in shown in the drawing.
Auf dem Eisenkern i des Transformators sitzen die Erregerwicklungen io und die Scheibenspulen 2 bis 9. In -dem Querschnitt der Scheibenspule 2 liegen die Leiter 32 der Ausgleichwicklung zwischen den Leitern 22 der Stufenwicklung. Die Leiter bestehen aus Kupferbändern, die zu einer doppelgängigen Spirale unter Zwischenlage von Isoliermaterial aufgewickelt sind. Entsprechendes gilt für die übrigen Spulen 3 bis 9. je zwei Scheibenspulen, z. B. 2 und 3, bilden eine Stufe. Die inneren Leiterenden der Stufenwicklung sind stufenweise durch die Leiter 2o, die inneren Leiterenden der Ausgleichwicklung durch die Leiter 3o miteinander verbunden.The excitation windings sit on the iron core i of the transformer io and the disc coils 2 to 9. In the cross-section of the disc coil 2 lie the conductors 32 of the equalizing winding between the conductors 22 of the step winding. The conductors consist of copper strips that form a double spiral underneath Intermediate layers of insulating material are wound. The same applies to the remaining coils 3 to 9. two disc coils each, e.g. B. 2 and 3, form a stage. The inner conductor ends of the step winding are stepped through the conductor 2o, the inner conductor ends of the equalizing winding are connected to one another by the conductors 3o.
Die .äußeren Leiterenden der Stufenwicklung sind an die einzelnen Stufenkontakte a bis e angeschlossen, die äußeren Leiterenden der Ausgleichwicklung abwechselnd an die Leiter 40, 41. Auf diese Weise sind sämtliche Windungen der Stufenwicklung in Reihe geschaltet, die den einzelnen Stufen entsprechenden Windungsgruppen der Ausgleichwicklung zueinander parallel geschaltet.The outer conductor ends of the step winding are to the individual Step contacts a to e connected, the outer conductor ends of the compensation winding alternately to conductors 40, 41. In this way, all turns of the step winding are connected in series, the winding groups of the corresponding to the individual stages Compensating winding connected in parallel to each other.
