Abstract

Die Erfindung betrifft eine stromkompensierte Drossel (1) mit einem Ringkern (23) mindestens zwei jeweils aus derselben Anzahl von Windungen (42.1, 42.2, 44.1, 44.2) bestehenden Wicklungen (41, 43), wobei im Inneren des Ringkerns (23) ein nicht leitender Körper (14) mit paarweise spiegelsymmetrisch zu einer Symmetrieachse (A-A) des Ringkerns ausgeführten Löchern (15.1, 15.2, 15.3, 15.4, 15.5, 15.6) angeordnet ist, wobei durch jedes Loch zumindest einiger der Paare symmetrischer Löcher (15.1, 15.4; 15.2, 15.5; 15.3, 15.6) jeweils eine Windung (42.1, 42.2, 44.1, 44.2) geführt ist, und durch die beiden zu einem Paar gehörenden Löcher (15.1, 15.4; 15.2, 15.5; 15.3, 15.6) einander entsprechende Windungen (42.1, 44.1; 42.2, 44.2) unterschiedlicher Wicklungen (41, 43) geführt sind und ein Verfahren zur Herstellung einer solchen stromkompensierten Drossel (1).

Figure imgaf001
The invention relates to a current-compensated choke (1) having a toroidal core (23) at least two windings (41, 43) each consisting of the same number of turns (42.1, 42.2, 44.1, 44.2), wherein inside the toroidal core (23) a not conductive body (14) is arranged with pairs of mirror-symmetrical holes (15.1, 15.2, 15.3, 15.4, 15.5, 15.6) in the form of an axis of symmetry (AA), through each hole at least some of the pairs of symmetrical holes (15.1, 15.4, 15.2 , 15.5, 15.3, 15.6) in each case one turn (42.1, 42.2, 44.1, 44.2) is guided, and through the two belonging to a pair of holes (15.1, 15.4, 15.2, 15.5, 15.3, 15.6) corresponding turns (42.1, 44.1, 42.2, 44.2) of different windings (41, 43) are guided and a method for producing such a current-compensated choke (1).
