Ringkern-Entstördrossel mit gerichtetem Streufeld.Toroidal core suppression choke with directed stray field.
Es ist bekannt, daß stromkompensierte Ringkerndrosseln, bei denen die stromdurchflossenen Wicklungen wegen der notwendigen Spannungsfestigkeit und der ebenfalls notwendigen Streuinduktivität, die zur Dämpfung von asymmetrischen Störungen erforderlich ist, mit Sektorenwicklungen aufgebaut sind, noch ein erhebliches ungerichtetes magnetisches Streufeld aufweisen. Dieses Streufeld beeinflußt z.B. in Fernsehempfängern die Geometrie des Bildes einer Bildröhre oder ein anderes Bauteil.It is known that current-compensated toroidal chokes, in which the current-carrying Windings because of the necessary dielectric strength and the also necessary leakage inductance, which is used to dampen asymmetrical Interference is required, with sector windings built up, yet another have a significant non-directional stray magnetic field. This stray field influences the geometry of the picture of a picture tube in television receivers, for example or another component.
Es war nun nach einer Lösung zu suchen, die das in Richtung z.B. der Bildröhre wirkende magnetische Streufeld auf ein Minimum reduziert, ohne dabei auf die notwendige Streuinduktivität zu verzichten, so daß keine Störungen bei magnetisch empfindlichen Bauteilen mehr auftreten können.A solution was now to be looked for, which would, for example, bring this in the direction of the picture tube acting magnetic stray field is reduced to a minimum without sacrificing the necessary stray inductance, so that no interference can occur more with magnetically sensitive components.
Die nachfolgend beschriebene Drossel, dargestellt in Figur 1 und 2, weist die geforderten vorteilhaften Eigenschaften auf.The throttle described below, shown in Figures 1 and 2, has the required advantageous properties.
Auf einem ferritischen Ringkern (1) ist zunächst die erste Wicklung (2) auf einem Ringsektor von beispielsweise 320° aufgebracht, dann eine Schutzisolierkappe (3). Auf diese Schutzkappe wird die zweite Wicklung (4) auf einem Ringsektor von beispielsweise etwa 200 symmetrisch zur ersten Wicklung, jedoch mit einem geringeren Drahtdurchmesser aufgebracht. Der dünnere Drahtdurchmesser ist notwendig, um die gleiche Windungszahl beider Wicklungen wegen der Bedingung der Stromkompensation zu erfüllen. Hierdurch ergibt sich der v/eitere Vorteil, daß ein an sich zur Einschaltstrombegrenzung notwendiger Ohm1scher Widerstand durch den Ohm'sehen Widerstand der zweiten Wicklung substituiert werden kann. Dadurch, daß diese zweite Wicklung (4) zur Gänze auf der Oberfläche der Ringkerndrossel angebracht ist, ist es leicht möglich, die entstehende Erwärmung an die Umgebung abzuführen.On a ferritic toroidal core (1), the first winding (2) is first applied to an annular sector of, for example, 320 °, then a protective insulating cap (3). The second winding (4) is applied to this protective cap on a ring sector of, for example, approximately 200, symmetrically to the first winding, but with a smaller wire diameter. The thinner wire diameter is necessary to meet the same number of turns in both windings because of the condition of current compensation. This results in the v / urther advantage that a shear se necessary for limiting the 1 ohm resistor can be substituted by the Ohm'sehen resistance of the second winding. Because this second winding (4) is attached entirely to the surface of the toroidal core choke, it is easily possible to dissipate the resulting heat to the environment.

Die so hergestellte Entstördrossel kann in einem Gehäuse (5) dergestalt montiert oder eingegossen werden, daß das resultierende magnetische Streufeld in der gewünschten Richtung austritt.The interference suppression choke produced in this way can be of this type in a housing (5) mounted or cast so that the resulting stray magnetic field emerges in the desired direction.
Nach der erfindungsgemäßen Drosselausgestaltung ergeben sich folgende Vorteile:According to the throttle configuration according to the invention, the following results Advantages:
1.) Die Stromkompensation ist annähernd ideal, jedenfalls besser als bei der herkömmlichen Bewicklung.1.) The current compensation is almost ideal, at least better than with conventional wrapping.
2.) Durch entsprechende Auswahl der gegenseitigen umfangsbezogenen überdeckung der ersten Wicklung (2) und der zweiten Wicklung (4) wird die notwendige Streuinduktivität eingestellt.2.) By appropriate selection of the mutual scope-related overlap the necessary leakage inductance is set in the first winding (2) and the second winding (4).
3.) Das resultierende magnetische Feld entsteht nur an der Stelle des Magnetkernes, die praktisch nicht von den Wicklungen (2, 4) überdeckt t wird. Damit ist es möglich, die Entstördrossel im Gerät geometrisch so 'i anzuordnen, daß z.B. die Bildröhre oder andere magnetisch empfindliche Bauelemente nicht mehr beeinflußt werden können.3.) The resulting magnetic field is generated only at the location of the magnetic core, which is practically not covered by the windings (2, 4) t. This makes it possible to geometrically arrange the interference suppression choke in the device in such a way that, for example, the picture tube or other magnetically sensitive components can no longer be influenced.
4.) Durch entsprechende Auswahl des Drahtdurchmessers der zweiten Wicklung kann der Wicklungswiderstand so dimensioniert werden, daß auch der Einschaltstromstoß aufgefangen werden kann, für den nach bisheriger Praxis ein gesonderter Ohm'scher Widerstand notwendig war.4.) By appropriate selection of the wire diameter of the second winding the winding resistance can be dimensioned so that the inrush current can also be absorbed, for the previous one In practice a separate ohmic resistor was necessary.
5.) Das resultierende magnetische Streufeld kann durch geeignete Orientierung in einem Gehäuse ausgerichtet werden.5.) The resulting stray magnetic field can be adjusted by suitable orientation be aligned in a housing.
