Description

Durch Windungsabschaltung regelbare Drosselspule U m die Induktiv ität von Drosselspulen, die in Wechselstromnetzen für die verschiedensten Zwecke häufig angewendet werden, beliebig regeln zu können, macht man häufig die Windungszahl veränderlich. Diese Regelung der Induktivität einer Drosselspule ist sehr einfach und betriebssicher. Sie hat jedoch den Nachteil, daß im allgemeinen nur wenig Regelstufen möglich sind, weil andernfalls dieZahl derAnzapfungen an derDrosselspule sehr groß wird.Choke coil U m die inductive, which can be regulated by switching off the turns ity of inductors used in AC networks for a wide variety of purposes are often used to be able to regulate at will, one often makes the number of turns changeable. This regulation of the inductance of a choke coil is very simple and operationally reliable. However, it has the disadvantage that generally only a few control stages are possible because otherwise the number of taps on the choke coil is very large will.

Um eine besonders vorteilhafte und feinstufige Regelung bei Drosselspulen zu erzielen, hat man diese auch bereits mit Sekundärwicklungen versehen, die eine große, unter Umständen veränderliche Windungszahl besitzen und über Widerstände kurzgeschlossen sind. Bei derartigen Drosselspulen ist eine wesentlich feinstufigere Regelung .möglich. Der Nachteil derartiger Drosselspulen besteht aber darin, daß der Aufwand an Kupfer für die beiden Wicklungen beträchtlich größer ist als wenn die Drosselspule -nur eine Wicklung besitzt.A particularly advantageous and finely tuned control for inductors to achieve, this has already been provided with secondary windings, the one have a large, possibly variable number of turns and resistances are short-circuited. In the case of such choke coils, there is a much finer level Regulation .possible. The disadvantage of such inductors is that the cost of copper for the two windings is considerably greater than if the choke coil has only one winding.

Nach der Erfindung wird eine erheblich feinstufigere Regelung bei durch Windungsabschaltung regelbaren Drosselspulen, dadurch erzielt, daß der beim Regeln abgeschaltete Teil der Drosselspulenwicklung über Widerstände (Ohmsche Widerstände, Induktivitäten oder Kapazitäten) geschlossen wird. Nach Bedarf können diese Widerstände veränderlich gemacht werden. Durch das Kurzschließen der abgeschalteten Wicklungsteile der Drosselspule kann die Regelung wesentlich feinstufiger gemacht werden, ohne daß der Aufwand an Kupfer für die Drosselspule erhöht wird.According to the invention, a considerably more finely graded regulation is used adjustable choke coils by turn-off, achieved in that the at Regulate the switched-off part of the inductor winding via resistors (ohmic resistances, Inductances or capacitances) is closed. These resistors can be used as required be made mutable. By short-circuiting the disconnected parts of the winding The regulation can be made much finer without using the choke coil that the cost of copper for the choke coil is increased.

Je nach der Art des verwendeten Widerstandes (Ohmscher Widerstand, Induktivität, Kapazität) können in dem von dem Widerstand und dem abgeschalteten Wicklungsteil gebildeten Kurzschlußstromkreis negative oder positive Amperewindungen erzeugt werden, die die Iriduktivität der Drosselspule weitgehend verändern.Depending on the type of resistor used (ohmic resistance, Inductance, capacitance) can be in that of the resistance and the switched off Winding part formed short-circuit circuit negative or positive ampere turns are generated, which largely change the iriductance of the inductor.

In der Abbildung ist als Ausführungsbeispiel eine einphasige Drosselspule dargestellt. i bedeutet die Drosselspule, 2 die Anzapfungen; mit 3 und d. sind die Zu- und Ableitungen der Drosselspule bezeichnet, die in einem beliebigen Regelstromkreis verwendet wird.The illustration shows a single-phase choke coil as an exemplary embodiment shown. i means the choke coil, 2 the taps; with 3 and d. are the Incoming and outgoing lines of the choke coil referred to in any control circuit is used.

bedeutet die beim Regeln abgeschalteten Windungen der Drosselspule, 6 den Widerstand, über den diese abgeschalteten Windungen für sich kurzgeschlossen sind.means the turns of the inductor that are switched off during regulation, 6 the resistance via which these turned-off windings are short-circuited for themselves are.

Die Erfindung kann bei Drosselspulen jeder Art Anwendung finden, beispielsweise auch bei Drosselspulen, die zum Zweck des Anlassens vor Wechselstrommotoren - etwa gemäß Patent zoo 995 - benutzt werden.The invention can be used with inductors of any kind, for example also with inductors that are used for the purpose of starting AC motors - for example in accordance with patent zoo 995 .
