Description

mittel zur Herabsetzung des induktiven Spannungsabfalles in einem einzelnen wechselstromdurchflossenen Leitungsglied Die Erfindung bezieht sich auf wechselstromdurchflossene Leitungsglieder, insbesondere solche, die große Stromstärken führen und bezweckt die Herabsetzung des induktiven Spannungsabfalles. Nun sind in Gestalt metallbewehrter Kabel solche Leiter bekannt, die auf ihre ganze Länge von. einem metallischen Mantel umschlossen sind. Diese Ummantelung vermag zwar das elektrische Feld abzuschirmen, nicht aber die Selbstinduktion und damit den induktiven Spannungsabfall wesentlich herabzusetzen. Dagegen wird eine beträchtliche Herabsetzung des induktiven Spannungsabfalles erfindungsgemäß dadurch erreicht, daß statt eines sich über die ganze Länge des Leiters erstreckenden metallischen Mantels in gewissen Abständen Eisenkerne mit sekundärer, toroidförmiger Kurzschlußbewicklung angeordnet werden.means to reduce the inductive voltage drop in one single AC-carrying line member The invention relates to AC-carrying line members, especially those with high currents lead and aims to reduce the inductive voltage drop. now are in the form of metal-armored cables such conductors are known that extend over their entire length from. are enclosed in a metallic jacket. This sheathing can do that shield the electric field, but not the self-induction and thus the inductive Reduce voltage drop significantly. On the other hand, there is a considerable reduction of the inductive voltage drop achieved according to the invention in that instead of one over the entire length of the conductor extending metallic jacket in certain Iron cores with secondary, toroidal short-circuit winding arranged at intervals will.

Nun ist zwar auch ein elektrischer Induktionsofen bekannt, bei dem die Schmelzrinne die Sekundäre eines Transformators bildet und konzentrisch zur Primärwicklung auf dem rahmenförmigen Kern des Transformators eine Kurzschlußwicklung angeordnet ist, welche weiterhin den die Schmelzrinne durchsetzenden Kernschenkel umschlingt. Aber abgesehen davon, daß es sich nicht um die Ausrüstung eines Leitungsgliedes im Sinne der vorliegenden Erfindung zum Schutze gegen induktiven Spannungsabfall handelt, vielmehr um eine Anordnung am Transformator eines Induktionsofens, dient die bekannte Anordnung nicht sowohl dem mit der Erfindung verfolgten Zweckgedanken als vielmehr der Übertragung der Induktionswirkung von dem von der Primären umfaßten Kernschenkel nach dem von der Schmelzrinne als Sekundärwicklung umfaßten Kernschenkel im Sinne einer Schubwicklung.Now an electric induction furnace is also known in which the melt channel forms the secondary of a transformer and is concentric to the Primary winding on the frame-shaped core of the transformer is a short-circuit winding is arranged, which continues to penetrate the melt channel through the core leg wraps around. But apart from the fact that it is not the equipment of a management link in the sense of the present invention for protection against inductive voltage drop is, rather an arrangement on the transformer of an induction furnace the known arrangement does not meet the intended purpose of the invention rather than the transfer of the induction effect from that comprised by the primary Core leg after the core leg encompassed by the melt channel as a secondary winding in the sense of a thrust winding.

Die Anwendung der Erfindung ist insbesondere gegeben bei sogenannten Hochstromleitungen mit großem Abstand zwischen Hin-und Rückleitung, wo also die Wirkung der sogenannten Gegenamperewindungen fehlt. Es ist nicht immer möglich, die beiden Leitungsglieder für Hin- und Rückleitung so nebeneinander zu legen, daß die vorstehend genannte Wirkung der teilweisen Aufhebung der Felder von Hin- und Rückleitung auftritt. In solchen Fällen bietet der Erfindungsgegenstand ein wirkungsvolles Mittel gegen den hohen induktiven Spannungsabfall.The application of the invention is given in particular in so-called High-current lines with a large distance between the outward and return lines, so where the The effect of the so-called counter amp windings is absent. It is not always possible to lay the two line links for the outward and return lines next to each other so that the aforementioned effect of partial cancellation of the fields of to and fro Return occurs. In such cases, the subject matter of the invention offers an effective one Means against the high inductive voltage drop.
