Description
Im Patent ist eine Schaltdrossel beschrieben, die zur Erleichterung der Stromunterbrechung in Wechselstromschalteinrichtungen, insbesondere Stromumformern, mit mechanischen Kontakten dient, indem durch sprunghafte Entsättigung ihres beim Nennstromwert hochgesättigten Magnetkerns jedesmal in der Nähe eines Stromnullwertes eine stromschwache Pause hervorgerufen wird. Der Kern ist zur Verbesserung seiner magnetischen Eigenschaften aus Eisenbandlagen flach übereinandergewickelt und hat vorzugsweise die Form eines Ringes. Damit die Eigenkapazität.der Schaltdrossel und ihre Kapazität gegen den Kern und gegen Erde möglichst gering ist, wird die Wicklung z. B. in Form von Scheibenspulen aufgebracht. Wegen der @ geschlossenen Ringform des Kernes können die Spulen nicht als Formspulen vorher gewickelt und nachträglich auf den Kern geschoben werden, sondern sie müssen auf den Kernen selbst unter Durchfädeln der einzelnen Windungen aufgewickelt werden.In the patent, a switching throttle is described, which makes it easier the current interruption in AC switching devices, especially current converters, with mechanical contacts is used by abrupt desaturation of their at Nominal current value of the highly saturated magnetic core every time in the vicinity of a current zero value a low-power pause is caused. The core is to improve it Magnetic properties of iron tape layers wound flat on top of each other and has preferably in the form of a ring. So that the self-capacitance of the switching reactor and If its capacity against the core and against earth is as low as possible, the winding becomes z. B. applied in the form of disc coils. Because of the @ closed ring shape of the core, the coils cannot be pre-wound as preformed coils and subsequently be pushed onto the core, but instead they have to be threaded onto the cores themselves of the individual turns are wound.
Nach der vorliegenden Erfindung kann die Wickelarbeit dadurch vereinfacht werden, daß an den Stirnseiten des Kernes über dessen Breite hinausragende Ringscheiben aus Isolierstoff mit Aussparungen für die Wicklungsspulen angebracht werden.According to the present invention, the winding work can thereby be simplified be that on the end faces of the core beyond its width protruding annular disks made of insulating material with recesses for the winding coils.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt, und zwar in Fig. i in Draufsicht und in Fig. 2 in Form eines Schnittes durch die Achse des Ringkernes.An exemplary embodiment of the invention is shown schematically in the drawing shown, namely in Fig. i in plan view and in Fig. 2 in the form of a section through the axis of the toroidal core.
Der Ringbandkern ist in Fig. 2 mit i r bezeichnet. Auf ihm befinden sich- die Scheibenspulen 12, von denen in Fig. i nur einige im Schnitt dargestellt sind. Zwischen Wicklung und Kern befinden sich gezahnte Ringscheiben 13, die beispielsweise aus Holz oder aus einem geschichteten Isolierfaserstoff od. dgl. bestehen können. Durch die Ringscheiben 13 wird die fertige Wicklung in vorteilhafter Weise versteift. Die beschriebene Ausführung der Schaltdrossel ist insbesondere vorteilhaft für sogenannte Kleinumformer mit einem Nennstrom in der Größenordnung von ioo Ampere.The toroidal tape core is denoted by i r in FIG. 2. Located on it the disc coils 12, of which only a few are shown in section in FIG are. Toothed ring disks 13 are located between the winding and the core, for example made of wood or a layered insulating fiber or the like. Can exist. The finished winding is advantageously stiffened by the annular disks 13. The described embodiment of the switching throttle is particularly advantageous for so-called Small converters with a nominal current in the order of magnitude of 100 amperes.
