Description

Drehstromtransformator mit fünfschenkligem Kern Es ist bekannt, Drehstromtransformatoren mit fünf in einer Ebene liegenden Schenkeln auszuführen, von denen die drei mittleren die Wicklungen tragen. Trotz dieser Anordnung ist die Streuung der in den drei Hauptschenkeln erzeugten Felder ungleich groß.Three-phase transformer with five-legged core Three-phase transformers are known to be carried out with five legs lying in one plane, of which the three middle ones wear the windings. Despite this arrangement, the spread is that in the three main legs generated fields of unequal size.

Dieser Nachteil der bekannten Konstruktion wird erfindungsgemäß dadurch behoben, daß je auf einem zwischen den Hauptschenkeln liegenden Jochteil und dem ihm zunächst liegenden Hilfsschenkel gegenläufig aufeinander geschaltete Ausgleichwicklungen angeordnet sind. Diese Ausgleichwicklungen ermöglichen es, die Streuung des mittleren Schenkels so weit zu erhöhen, daß sie denselben Wert erreicht, auf welchen infolge der Wirkung der Ausgleichwicklungen die Streuung der weiter außen liegenden Hauptschenkel herabgesetzt ist.According to the invention, this disadvantage of the known construction is thereby eliminated fixed that each on a yoke part lying between the main legs and the Compensating windings connected to one another in opposite directions are arranged. These equalizing windings make it possible to reduce the spread of the mean Schenkels so far that it reaches the same value to which as a result the effect of the equalizing windings is the scattering of the main legs further out is reduced.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt. Mit i ist der Transformatorkern bezeichnet. 2, 3 und ¢ sind die drei mittleren Schenkel (Hauptschenkel) dieses Kernes, welche die Primärwicklungen, 5, 6 und 7 und die Sekundär-Wicklungen 8, 9 und io tragen. i i und 12 sind die beiden Hilfsschenkel. 13 und 1q. sind die beiden Teile einer von vier Ausgleichwicklungen. Die Spule 13 ist auf einem die Schenkel 3 und q. verbindenden Jochteil untergebracht, während die Spule 14 auf dem diesem Jochteil zunächst liegenden Hilfsschenkel 12 angeordnet ist. Beide Spulen sind gegeneinander geschaltet. Die Anordnung der anderen drei Ausgleichwicklungspaare entspricht der eben geschilderten Anordnung des Wicklungspaares 13 und 1q..An embodiment of the invention is shown in the drawing. The transformer core is denoted by i. 2, 3 and ¢ are the three middle legs (Main leg) of this core, which contains the primary windings, 5, 6 and 7 and the secondary windings Wear 8, 9 and io. i i and 12 are the two auxiliary legs. 13 and 1q. are the both parts one of four equalizing windings. The coil 13 is on a die Leg 3 and q. connecting yoke part housed while the coil 14 on the auxiliary leg 12 lying next to this yoke part is arranged. Both coils are switched against each other. The arrangement of the other three equalizing winding pairs corresponds to the just described arrangement of the winding pair 13 and 1q ..
