Description

mittels eines beweglichen magnetischen Nebenschlusses regulierbarer Transformator mit unterteilter Primär- und Sekundärwicklung Die Erfindung bezieht sich auf Transformatoren, die mittels eines beweglichen magnetischen Nebenschlusses regulierbar sind. Die Erfindung besteht darin, daß sowohl die Primärwicklung als auch die Sekundärwicklung in mehrere hintereinandergeschaltete Spulen verschiedener Größe unterteilt ist, und daß einer großen Primärspule eine kleine Sekundärspule und umgekehrt eine kleine Primärspule einer großen Sekundärspule auf dem gleichen Kernschenkel zugeordnet ist und die so gebildeten Teiltransformatoren zu beiden Seiten des magnetischen Nebenschlusses angeordnet sind. Es sind zwar schon Transformatoren bekannt, deren Sekundärwicklungen in Spulen verschiedener Größe unterteilt sind, die auf verschiedenen Schenkeln des Transformatorkerns sitzen. Allein einer solchen geteilten Sekundärwicklung hatte man immer nur eine einzige Primärwicklung zugeordnet, die auf der leinen Seite des magnetischen Nebenschlussies saß, während bei der Erfindung im Gegenteil. jeder Sekundärwicklung eine besondere Primärwicklung zugeteilt ist, die mit ihr auf dem gleichen Transformatorschenkel und auf der gleichen Seite des magnetischen Nebenschlusses sitzt. Man erzielt dadurch eine größere Regnli!erbarkeit, wobei zugleich der Sekundärstrom verstärkt und die magnetischen Verluste vermindert werden.adjustable by means of a movable magnetic shunt Transformer with divided primary and secondary winding The invention relates focus on transformers that operate by means of a moving magnetic shunt are adjustable. The invention consists in that both the primary winding as also the secondary winding in several different coils connected in series Size is divided, and that a large primary coil is a small secondary coil and vice versa a small primary coil of a large secondary coil on the same Core leg is assigned and the partial transformers formed in this way to both Sides of the magnetic shunt are arranged. They are transformers already known, the secondary windings of which are divided into coils of different sizes, which sit on different legs of the transformer core. Alone such split secondary winding was only ever assigned to a single primary winding, who sat on the leash side of the magnetic shunt while in the invention on the contrary. each secondary winding is assigned a special primary winding, those with her on the same transformer leg and on the same side of the magnetic shunt sits. This results in greater rainability, at the same time the secondary current is amplified and the magnetic losses are reduced will.

Die Erfindung ist in der Zeichnung schematisch dargestellt.The invention is shown schematically in the drawing.

Der gezeigte Transformator ist ein Spartransformator, der an .den Klemmen i i und 13 mit Primärstrom gespeist wird, während an den Klemmen i i und 12 der Sekundärstrom abgenommen wird. Sowohl die Primärwicklung als auch die Sekundärwicklung bestehen aus je vier hintereinandergeschalteten Spulen verschiedener Größe; von denen je zwei eine größere, die beeiden anderen eine kleinere Anzahl von Windungen hesitzen. Nun besteht die Erfindung darin, daß den beiden großen Primärspulen 15, 16 die beiden Sekundärspulen 19, 20 und den beiden kleinen Primärspulen 14, 1 7 die großen Sekundärspulen 18, 21 zugeordnet sind, wobei jede Primärspule mit ihrer Sekundärspule auf dem gleichen Kernschenkel des Transformators und auf -der gleichen Seite des als ma.gneti,-scher Nebenschluß dienenden beweglichen Eisenkörpers 22 angeordnet ist. Diese durch je eine Primär- und eine Sekundärspule gebildeten Teiltransformatoren 1q., 18 bzw. i5,.i9 und 16,20 sowie 17, 21 sind zu beiden Seiten des magnetischen Nebenschlusses 22 angeordnet. Durch den in den Spulen durch gegenseitige Einwirkung entstehenden Kompensationsstrom können die Spannungsver# luste im Sekundärstromkreis ausgeglichen werden. Anstatt die Primär- und Sekundärspulen hintereinanderzuschalten, könnte man sie in bekannter Weise auch parallel schalten.The transformer shown is an autotransformer, which is fed with primary current at terminals ii and 13, while the secondary current is drawn from terminals ii and 12. Both the primary winding and the secondary winding consist of four series-connected coils of different sizes; two of which have a larger number of turns, the other two have a smaller number of turns. The invention now consists in that the two large primary coils 15, 16 are assigned the two secondary coils 19, 20 and the two small primary coils 14, 17 are assigned the large secondary coils 18, 21, each primary coil with its secondary coil on the same core leg of the transformer and is arranged on the same side of the movable iron body 22 serving as a magnetic shunt. These partial transformers 1q., 18 or i5, .i9 and 16, 20 and 17, 21 each formed by a primary and a secondary coil are arranged on both sides of the magnetic shunt 22. The voltage losses in the secondary circuit can be compensated for by the compensation current that arises in the coils as a result of mutual action. Instead of connecting the primary and secondary coils in series, they could also be connected in parallel in a known manner.
