Description

Eisengeschlossene Drossel oder Transformator, insbesondere zur Verwendung als Vorschaltgerät für Leuchtstofflampen Es ist bekannt, daß die Methode, Wickellänge und aktive Eisenkernlänge zu vergrößern, um zu einem Vorschaltgerät langgestreckter Schmal-Niiedrig-Bauform zu kommen, magnetisch schlecht ist, die magnetischen Eigenschaften des Gerätes verdirbt und in der Praxis große Schwierigkeiten bringt. Dies besonders deshalb, weil bei eitler Streckung des Eisenkerns in solcher Richtung der für den -Materialaufwand entscheidende magnetische Widerstand immer größer wird und einen höheren Erregungsaufwand erfordert. Wenn diese Nachteile vermieden werden sollen, muß verhindert werden, daß, wie es bei dem oben angegebenen Verfahren der Fall ist, mit wachsender Gerätelänge aktive Eisenweglänge und magnetomotorische Kraft wachsen.Closed iron choke or transformer, in particular for use As a ballast for fluorescent lamps It is known that the method, winding length and increase active iron core length to make a ballast more elongated Narrow-low design to come, magnetically poor, the magnetic properties of the device spoils and causes great difficulties in practice. This especially because with vain stretching of the iron core in such a direction the for the -Material cost decisive magnetic resistance is getting bigger and bigger requires higher arousal effort. If these disadvantages are to be avoided, it must be prevented that, as is the case with the procedure given above, with increasing device length, the active iron path length and magnetomotive force increase.

Die hier beschriebene Erfindung vermeidet diese Nachteile dadurch, daß sie von einer Kernanordnung ausgeht, deren Eigenschaften mit wachsender Länge des Gerätes magnetisch keine Nachtteile bringen, im Gegenteil, bei der hier vorgeschlagenen Kernanordnung wird der aktive Eisen Auerschnitt mit wachsender (.äuge und gleichem Querschnittsprofil des Gerätes sogar noch vergröbert, wobei noch dazu die aktive Eisenweglänge konstant gehalten wird.The invention described here avoids these disadvantages by that it starts from a core arrangement whose properties increase with length of the device magnetically do not bring any disadvantages, on the contrary, with the one proposed here Core arrangement becomes the active iron cutout with growing (.eye and like The cross-sectional profile of the device is even coarser, with the active one at that Iron path length is kept constant.

Die Erfindung schlägt vor, um einen in der Längenrichtung des Gerätes langgestreckten, schleifenartigen Wickel herum, d@2ssen Achse senkrecht zur Längendimension des Gerätes steht und im Verhältnis zur Wickellänge kurz ist. den Eisenkern so anzuordnen, daß er die beiden langgestreckten geraden Wickelsträngc allseitig umschließt.The invention proposes one in the longitudinal direction of the device elongated, loop-like winding around, the axis perpendicular to the length dimension of the device and is short in relation to the winding length. to arrange the iron core so that that it encloses the two elongated straight winding strands on all sides.

Der aktive Eisenkern ist dabei aufgebaut aus U-förmig gebogenen, abgekanteten, gekröpften Blechen oder aus derartigen U-förmigen Blechen und J-förrnig geschnittenen Blechen, die die Wickelstränge in ihrem ganzen gerad.liriien Verlauf ein- und, umschließen.The active iron core is made up of U-shaped bent, beveled, Cranked sheets or cut from such U-shaped sheets and J-shaped sheets Sheets that enclose and enclose the winding strands in their entire straight, linear course.

Der oder die' 13.-tricbsluftspaIte kennen dabei an beliebiger Stoßstelle der Kerne entstehen und in bekannter Weise eingestellt werden.The 13th tricbs air gap (s) know at any joint of the cores arise and are adjusted in a known manner.

1n der Zeichnung sind beispielsweise Ausführungsformen der Erfindung wiedergegeben, Es zeigen Fig. 1 und 2 einen Längsschnitt und Fig. 3, 4 und 5 einen Querschnitt der Drossel.1n the drawing are exemplary embodiments of the invention 1 and 2 show a longitudinal section and FIGS. 3, 4 and 5 show a Cross section of the throttle.

1 bezeichnet dien Wickel, 2 den E-förmig, 3 dien I-förmig, 2a, 2b den doppel-E-förmig zusammengesetzten Eisenkernteil. Aus der Zeichnung ist ersichtlich, daß die Anordnung etwa der gewoihnten Form einer langen Drc.ssel, z. B. einer Kerndrossel, mit vertauschten Rollen zwischen Kupfer und Eisen entspricht. Diese Bauform ist anwendbar für Mantelals auch Kerntypen in allen ihren Variationen, in symmetrischer oder unsymmetrischer Eisenkern- oder Wickelanordnung. Es können also außer symmetrischen Kern- und Wickelanordnungen sowohl entsprechend der Mantelbauweise unsymmetrische Eisenkernanordnungen als auch entsprechend der Kernbauweise unsymmetrische Wickelanordnungen verwendet Werden.1 denotes the coil, 2 the E-shaped, 3 the I-shaped, 2a, 2b the double-E-shaped composite iron core part. From the drawing it can be seen that the arrangement is roughly the usual shape of a long Drc.ssel, e.g. B. a core choke, with exchanged roles between copper and iron. This design can be used for sheaths as well as core types in all their variations, in a symmetrical or asymmetrical iron core or winding arrangement. In addition to symmetrical core and winding arrangements, iron core arrangements which are asymmetrical in accordance with the shell construction and also winding arrangements which are asymmetrical in accordance with the core construction can be used.

Die hier geschilderte Anordnung ergibt relativ geringen Querschnitt, aber große Länge des Einbauraumes, bei großem aktivem Querschnitt geringe Eisen Weglänge. Das wesentliche Kriterium dieser Anordnung besteht darin, daß dne magnetischen Leitwerte solcher Kernanordnungen mit kurzen Wickeiachs,en im Vergleich zu Anordnungen mit langen Wickelachsen sehr viel größer werden. Damit steigt bekanntlich die magnetische Güte.The arrangement described here results in a relatively small cross-section, but large length of the installation space, with a large active cross-section low iron Path length. The essential criterion of this arrangement is that the magnetic Conductance values of such core arrangements with short winding axes compared to arrangements become much larger with long winding axles. As is well known, this increases the magnetic Quality.
