Abstract

Eine Schwingdrossel weist einen symmetrischen Doppel-E-Kern auf. Dieser hat zwei geometrisch gleiche Wicklungsfenster, einen quaderförmigen Mittelschenkel (17) und zwei quaderförmige Aussenschenkel (18, 19). Der Doppel-E-Kern ist so ausgeführt, dass die Querschnittsfläche des Mittelschenkels (17) grösser als 90 mm2 ist, wobei als Längsschnitt der Schnitt anzusehen ist, der den Doppel-E-Kern in zwei einfache E-Kerne trennen würde, und der Querschnitt zum Längsschnitt derart senkrecht steht, dass im Querschnitt das Doppel-E erkennbar ist, wobei sich der Doppel-E-Kern in einem Bauelementevolumen kleiner 26,5 mm x 26,5 mm x 15 mm (Breite x Tiefe x Höhe) befindet.
