Description

Die vorliegende Erfindung betrifft eine elektrische Filteranordnung, bei der parallel zum Nutzkreis ein auf die zu unterdrückende Frequenz abgestimmtes Kurzschlußglied und in Serie mit der Selbstinduktion des Kurzschlußgliedes eine magnetische Kopplungsspule vorgesehen ist, durch welche die infolge des Ohmschen Widerstandes des Kurzschlußgliedes nicht unterdrückte Wechsel-Stromkomponente kompensiert wird. Derartige Anordnungen haben den meist gebräuchlichen, aus Kettenleitern bestehenden Filtern gegenüber den Vorteil, daß die elektromotorischen Kräfte, die durch die zu unterdrückende Wechselstromkomponente erzeugt werden, einander aufheben, ohne daß ein Nebenweg für die Wirkkomponente erforderlich wäre.The present invention relates to an electrical filter assembly in which parallel to the useful circuit a short-circuit element matched to the frequency to be suppressed and in series with the self-induction of the short-circuit member, a magnetic coupling coil is provided through which the as a result of the ohmic resistance of the short-circuit element not suppressed alternating current component is compensated. Such arrangements have the most common one consisting of chain ladders Filters over the advantage that the electromotive forces caused by the to suppressing AC components are generated cancel each other without a byway for the active component would be required.

Eine derartige bekannte Schaltung ist auf der Zeichnung in Abb. 1 schematisch dargestellt. Such a known circuit is shown schematically in the drawing in FIG.

Es bedeuten 1 die Stromzuführungsklemmen, die mit den Belastungsklemmen 2 unter Zwischenschaltung eines Filters verbunden sind, bestehend aus Spulen 3 und 4, die auf einen Kern 5 gewickelt sind, und aus einer Spule 6 und einem Kondensator 7, die in Reihe zwischen einer der Klemmen 1 und der Verbindung zwischen den Spulen 3 und 4 angeschlossen sind. Die Wechselkomponente des durch die Klemmen 1 gelieferten Stromes wird durch die Spulen 3 und 6 geschickt, und es entsteht wegen der induktiven Beziehung zwischen den Spulen 3 und 4 in der Spule 4 eine EMK, die die EMK der Spule 6 und des Kondensators 7 aufhebt und den Wechselstrom von dem Nutzkreis abschließt.It denotes 1 the power supply terminals, which are connected to the load terminals 2 below Interposition of a filter, consisting of coils 3 and 4, which are connected to a core 5 are wound, and a coil 6 and a capacitor 7, which in Series connected between one of terminals 1 and the connection between coils 3 and 4 are. The alternating component of the current supplied by terminals 1 is sent through coils 3 and 6, and it arises because of the inductive relationship between the coils 3 and 4 in the coil 4 an EMF, which the EMF of the coil 6 and the Capacitor 7 cancels and terminates the alternating current from the utility circuit.

Vorliegender Erfindung gemäß wird parallel der der Kompensation dienenden Induktionsspule des Kurzschlußgliedes eine Selbstinduktion in Serie mit einem Ohmschen Widerstand gelegt.According to the present invention, the induction coil used for compensation is parallel of the short-circuit element, a self-induction is placed in series with an ohmic resistance.

Es hat sich gezeigt, daß die bekannten Anordnungen gemäß Abb. 1 für eine Leitung and Belastung gute Resultate geben; wo aber die Belastungen sich beträchtlich ändern,It has been shown that the known arrangements according to Fig. 1 for a line and strain give good results; but where the loads change considerably,

hat sich gezeigt, daß eine Schaltung gemäß der Erfindung gegenüber solchen Änderungen weit unempfindlicher ist. Da nämlich die Filterwirkung dadurch erzeugt wird, daß eine induktive Spannung gegen eine andere ausgeglichen wird, müssen die verschiedenen Elemente so bemessen werden, daß dieser Ausgleich auch bei allen Belastungen aufrechterhalten bleibt, was durch Anordnungit has been shown that a circuit according to the invention can withstand such changes is far less sensitive. Because the filter effect is generated by the fact that one inductive voltage is balanced against another, the different Elements are dimensioned in such a way that this balance is maintained even with all loads what remains by arrangement

ίο des Nebenschlußweges erreicht wird.ίο the shunt path is reached.

Die Erfindung ist schematisch in den Abb. 2 und 3 dargestellt.The invention is shown schematically in Figs.

Die Schaltung gemäß Abb. 2 unterscheidet sich von der bekannten gemäß Abb. 1 dadurch, daß im Nebenschluß zur Spule 3 eine Spule 8 und ein Widerstand 9 angeordnet sind. Zweckmäßigerweise ist im Nebenschluß ein Kondensator 10 vorgesehen, der vom Bclastungskreis eine etwaige Wechselstromkomponente absperrt, die der Strom nach Passieren des Filters noch besitzen könnte. Naturgemäß muß der Kondensator 10 so bemessen werden, daß er mit den mit ihm in Reihe liegenden Induktanzen nicht in Resonanz ist.The circuit according to Fig. 2 differs from the known one according to Fig. 1 in that that in the shunt to the coil 3, a coil 8 and a resistor 9 are arranged are. Appropriately, a capacitor 10 is provided in the shunt, which is from the load circuit blocks any alternating current component that the current could still have after passing through the filter. Naturally, the capacitor 10 must be dimensioned so that it can with the with him in Series lying inductances is not in resonance.

Wie Abb. 3 zeigt, kann die Spule 6 auf denselben Kern gesetzt werden wie die Spulen 3 und 4.As Fig. 3 shows, the coil 6 can be placed on the same core as the coils 3 and 4.
