Description

Betriebsmäßig regelbare Drosselspule mit beweglichem Jochstück Die Erfindung betrifft eine Drosselspule mit regelbarem magnetischem Widerstand. Man hat bisher die Eisenkerne solcher Drosselspulen aus zwei gegeneinander beweglichen Teilen hergestellt. DieTeile sind durch Luftspalte voneinander getrennt, deren Weiten geregelt werden können.Operationally adjustable choke coil with movable yoke piece Die The invention relates to a choke coil with adjustable magnetic resistance. Man So far, the iron cores of such inductors consisted of two mutually movable coils Parts manufactured. The parts are separated from each other by air gaps, their widths can be regulated.

Eine solche Drosselspule zeigt schematisch die Abb. i der Zeichnung. Der Eisenkern besteht aus zwei U-förmigenBlechpaketeni,2, von denen das obere, i, gegen das untere, 2, verschoben und dadurch die Weite der Luftspalte 3 geregelt «-erden kann. Beide Teile umschließen beispielsweise eine durchgehende Sammelschiene -., deren Spannungsabfall durch die Drossel erhöht werden soll.Such a choke coil is shown schematically in Fig. I of the drawing. The iron core consists of two U-shaped sheet metal stacks i, 2, of which the upper, i, moved towards the lower one, 2, and thereby the width of the air gap 3 is regulated «-Can earth. Both parts enclose a continuous busbar, for example -., whose voltage drop is to be increased by the choke.

Solche Drosseln haben den "Nachteil, daß sie besonders in der Stellung geringsten magnetischen Widerstandes stark nach dem Leiter .I und in die äußere Umgebung streuen. Die Streulinien induzieren in den benachbarten Metallteilen Wirbelströme. Diese Teile werden erhitzt. außerdem werden die Verltiz;te im Leiter .I vergrößert.Such chokes have the "disadvantage that they are particularly in the position lowest magnetic resistance strong after the conductor .I and in the outer Scatter the surrounding area. The scatter lines induce eddy currents in the neighboring metal parts. These parts are heated. In addition, the casualties in ladder .I are increased.

Erfindungsgemäß wird zur Verminderung der Streuung in jedem Schenkel eine Reihe von betriebsmäßig regelbaren Luftspalten angebracht.According to the invention, to reduce the scatter in each leg a number of operationally adjustable air gaps attached.

Das Schema einer solchen Drosselspule zeigt die Abb. 2. Hier enthält jeder Schenkel zwei Luftspalte 3a, 3b. In den Luftspalten sind magnetische Zwischenstücke 5 angeordnet, die ein Zusammenziehen der Kraftlinien bewirken. Es wird dadurch die Streuung der Drossel bedeutend herabgesetzt.The scheme of such a choke coil is shown in Fig. 2. Here contains each leg has two air gaps 3a, 3b. There are magnetic spacers in the air gaps 5 arranged, which cause a contraction of the lines of force. It becomes the The spread of the throttle is significantly reduced.

Die Regelung der Drosselspule kann dadurch erfolgen, daß man entweder die Weite der einzelnen Luftspalte einer Reihe nacheinander oder gemeinsam ändert. Eine Regelvorrichtung der ersten Art zeigt die Abb. 3, eine Regelvorrichtung der zweiten Art die Abb. 4.The regulation of the choke coil can be done by either the width of the individual air gaps in a row changes one after the other or together. A control device of the first type is shown in Fig. 3, a control device of the second type, Fig. 4.

In Abb. 3 ist jeder Schenkel aus mehreren quaderförmigen Blechpaketen 5a bis 5c aufgestapelt. Jedes Blechpaket hat vorspringende Bolzen 6, womit es in Schlitze 7 der Laschen 8 greift, die an dem darüber angeordneten Blechpaket oder am Jochstück i befestigt sind. Beim Anheben des Jochstückes werden nacheinander zunächst das Jochstück, dann die Blechpakete 5a, 5b, 5` von ihrer Unterlage abgehoben und dadurch schrittweise Luftspalte 3a, 3b, 3c in den Eisenschenkel eingeschaltet.In Fig. 3, each leg is made up of several cuboid sheet metal stacks 5a to 5c stacked. Each laminated core has protruding bolts 6, with which it is in Slits 7 of the tabs 8 engages, which on the laminated core arranged above or are attached to the yoke piece i. When lifting the yoke piece are successively first the yoke piece, then the laminated cores 5a, 5b, 5 'lifted from their base and thereby gradually switched on air gaps 3a, 3b, 3c in the iron leg.

Die Abb.3 zeigt verschiedene Ausführungsformen der Verbindungslaschen B. Sie können entweder gelenkig oder fest an den Blechpaketen angebracht werden. Statt der Laschen 8 können auch Ketten oder biegsame Verbindungsteile, z. B. Seile, verwendet werden.Figure 3 shows different embodiments of the connecting straps B. They can be attached to the laminated cores either in an articulated manner or in a fixed manner. Instead of the tabs 8, chains or flexible connecting parts, e.g. B. ropes, be used.

Bei der Ausführung nach Abb. 3 sind im allgemeinen die Luftspalte verschieden weit. Die oberen Luftspalte 3a, 3b haben die größtmögliche Weite A, der Luftspalt 3c hat eine wesentlich kleinere Weite a, bei 3d ist praktisch überhaupt noch kein Luftspalt vorhanden.In the embodiment according to Fig. 3, the air gaps are generally different far. The upper air gaps 3a, 3b have the largest possible width A, the air gap 3c has a much smaller width a, at 3d is practical at all there is no air gap yet.

Abb. q. zeigt ein Getriebe, bei dem sämtliche Luftspalte in allen Regelstellungen wenigstens annähernd gleich sind. Hier sind die einzelnen Blechpakete an Gelenkeng von Nürnberger Scheren io befestigt.Fig.q. shows a transmission in which all air gaps in all Control positions are at least approximately the same. Here are the individual sheet metal packages attached to the joints of Nuremberg scissors io.

Um das Aneinanderkleben der Blechpakete zu verhüten, können, wie Abb. 5 zeigt, zwischen benachbarten Paketen 5a, 5b keilförmige Beilagen i i aus unmagnetischem Material, beispielsweise aujs Isoliermaterial, eingeschoben werden.In order to prevent the laminated cores from sticking together, as shown in Fig. 5 shows wedge-shaped inserts i i made of non-magnetic between adjacent packets 5a, 5b Material, for example from insulating material, can be inserted.
