Description

Lichtbogenschweißtransformator mit dreiphasiger Primär- und einphasiger Sekundärwicklung Das Patent 583 934 betrifft einen Lichtbogenschweißtransformator mit dreiphasiger Primär- und einphasiger Sekundärwicklung, welch letztere auf einem zylindrischen, axial verschiebbaren Eisenkörper sitzt, bei dem ein mit einer Kurzschlußwicklung versehener Hilfseisenkörper auf der Achse des verschiebbaren Eisenkörpers drehbar gelagert ist.Arc welding transformer with three-phase primary and single-phase Secondary winding Patent 583,934 relates to an arc welding transformer with three-phase primary and single-phase secondary winding, the latter on one cylindrical, axially displaceable iron body sits, in which one with a short-circuit winding provided auxiliary iron body rotatable on the axis of the movable iron body is stored.

Dieser Hilfseisenkörper verhält erfindungsgemäß noch eine weitere mit Gleichstrom gespeiste Wicklung, die als verteilte Wicklung angeordnet sein kann oder auch als solche für ausgeprägte Pole. Sie dient zur Verbesserung des Leistungsfaktors. Die dazu erforderliche Leistung ist nur gering und kann deshalb gut durch einen Trockengleichrichter abgegeben werden, der auch wegen des bei Schweißanlagen muhen Betriebes angebracht sein dürfte und sogar innerhalb des Trafogehäuses mit -untergebracht werden kann. Dabei ergibt sich weiter die Möglichkeit, für den Gleichrichter ohne besonderen Transformator auszukommen. Man kann nämlich den Stätor gleichzeitig als Autotransformator benutzen, indem man Anzapfungen der Statorwicklung zur Speisung des Gleichrichters heranzieht.According to the invention, this auxiliary iron body behaves still another DC fed winding which can be arranged as a distributed winding or as such for pronounced poles. It serves to improve the power factor. The performance required for this is only small and can therefore easily be achieved by a Dry rectifiers are issued, which is also due to the low in welding systems Operation should be appropriate and even housed within the transformer housing can be. There is also the possibility of using the rectifier without to get along with a special transformer. Namely, you can use the stator at the same time as Use autotransformer by tapping the stator winding for power supply of the rectifier.
