Description
Die Erfindung bezieht sich auf einen Regeltransformator oder auf eine regelbare Drosselspule, die einen dreischerikeligen Eisenkern besitzen und bei denen zur Einstellung der Induktivität eine Gleichstromvormagnetisierungswicklung auf dem mittleren Schenkel vorgesehen ist.The invention relates to a regulating transformer or on an adjustable choke coil with a three-core iron core and where a DC bias winding is used to adjust the inductance is provided on the middle leg.
Bei bekannten Transformatoren, die einen dreischerikeligen Eisenkern haben, ist die Primärwicldung auf dem einen Außenschenkel, die Sekundärwicklung auf dem. zweiten Außenschenkel und die Wicklung für die Gleichstromvormagnetisaerung auf dem mittleren Schenkel angeordnet. Hierbei können, insbesondere wenn die Sättigung in dem als Streusteg ausgebildeten mittleren Schenkel eine gewisse Grenze überschreitiet, Streulinien auf irgendwelchen unregelmäßig gestalteten Wegen aus den. Wicklungen austreten. Das zo verursacht erhebliche Zusatzverluste.In known transformers having a dreischerikeligen iron core, the Primärwicldung is on an outer leg, the secondary windings on the. second outer leg and the winding for the DC bias is arranged on the middle leg. In this case, especially if the saturation in the middle leg designed as a scattering web exceeds a certain limit, scattering lines can emerge from the irregularly shaped paths. Windings leak out. The zo causes considerable additional losses.
Aufgabe der Erfindung ist es, einen Transformator oder eine Drosselspule bei geringen Verlusten leicht regelbar zu gestalten und diesen Apparaten einen einfachen Aufbau zu geben.The object of the invention is to provide a transformer or a choke coil at low To make losses easily controllable and to give these devices a simple structure give.
Das wird erfindungsgemäß dadurch erreicht, daß der .mittlere Schenkel einen Streupfad für die Sekundärwicklung bildet, die den mittleren Schenkel mit der Vormagnetisierungswicklung und den die Erregerwick-• lung tragenden einen äußeren Schenkel umfaßt. Der zweite äußere Schenkel bleibt unbewickelt. This is achieved according to the invention in that the middle leg forms a scattering path for the secondary winding which the middle leg with the bias winding and the exciter winding • ment carrying an outer leg includes. The second outer leg remains unwound.
In der Figur ist ein Ausführungsbeispiel eines Transformators gemäß der Erfindung dargestellt. Der Eisenkern 1 hat die beiden äußeren Schenkel 2 und 3 und einen mittleren Schenkel 4, der die Gleichstromvormagnetisierungswicklung 5 trägt. Die Gleichstromvormagnetisierung kann in bekannter Weise geregelt werden, und zwar entweder -durch Zu- und Abschalten von Windungen der im Gleichstromkreis liegenden Vormagnetisierungswicklung oder durch Ändern der Größe eines regelbaren Widerstandes in dem Gleichstromkreis bei Verwendung einer Vormaignetisierungswicklung ohne Anzapfungen. Die Erregerwicklung 6 ist auf dem äußeren Schenkel 2 angeordnet. Der mittlere Schenkel 4 mit der Wicklung 5 und der äußere Schenkel 2 mit der Wicklung 6 werden von der Sekundärwicklung 7 umfaßt. An diese können Verbraucher angeschlossen werden, denen .eine, regelbare Spannung zuzuführen ist, z.B. Schweißapparate, Gleichrichter oder Motoren. Die Sekundärwicklung kann aber auch durch Widerstände belastet werden, die gegebenenfalls regelbar sind. Dann läßt sich der Apparat als Drosselspule, z.B. in ErdschluBschutZSchalrungen bzw. zur Kompensation des Erdschlußstromes, verwenden.In the figure is an embodiment of a transformer according to the invention shown. The iron core 1 has the two outer legs 2 and 3 and a middle one Leg 4, which is the DC bias winding 5 carries. The DC bias can be controlled in a known manner, either -by connecting and disconnecting turns of the bias winding in the direct current circuit or by changing the size of an adjustable resistor in the DC circuit when using a pre-marking winding without taps. The excitation winding 6 is on the outer Leg 2 arranged. The middle leg 4 with the winding 5 and the outer one Legs 2 with winding 6 are encompassed by secondary winding 7. To this Consumers can be connected to which a controllable voltage can be supplied e.g. welding machines, rectifiers or motors. The secondary winding can, however are also burdened by resistances, which can be regulated if necessary. Then you can the apparatus as a choke coil, e.g. in earth-fault protection circuits or to compensate for the earth fault current.
