Description

Verbundleiter für elektrische Freileitungen Verbundleiter für elektrische Freileitungen bestehen in der Regel aus Leitungsdrähten, die um einen Tragkern aus Eisen- oder Stahldrähten in Form eines Seiles oder einer Drahtschraube oder beides verseilt sind.Composite conductors for electrical overhead lines Composite conductors for electrical Overhead lines are usually made up of line wires that surround a support core Iron or steel wires in the form of a rope or a wire screw or both are stranded.

Man hat bisher angenommen, daß bei dieser Anordnung des Eisens im Innern des Leiters schädliche, d. h. Verluste verursachende, magnetische Kraftflüsse im Kern nicht entstehen.It has hitherto been assumed that with this arrangement of the iron in the Inside the conductor harmful, d. H. Loss-causing magnetic fluxes of force do not arise in the core.

Es wurde jedoch nunmehr gefunden, daß auch in diesem Falle Energieverluste durch Hysterese und Wirbelströme vorkommen.However, it has now been found that in this case too, energy losses occur through hysteresis and eddy currents.

Nach der Erfindung soll, um diese zu verringern oder zu vermeiden, für den Tragkörper ein Metall benutzt werden, das neben hoher Druck- und Zugfestigkeit die Eigenschaft hat, daß es nicht magnetisierbar ist, wie beispielsweise Bronze oder eine nicht oder nur äußerst schwach magnetisierbare Eisenlegierung. Eine weitere Möglichkeit zur Herabsetzung der Verluste besteht für den Fall der Verwendung schwach magnetisierbarer Metalle darin, daß man Metalle mit geringeren Hysteresisverlusten auswählt.According to the invention, in order to reduce or avoid this, a metal can be used for the support body, which in addition to high compressive and tensile strength has the property that it is not magnetizable, such as bronze or a non-magnetizable or only extremely weakly magnetizable iron alloy. Another There is a possibility of reducing the losses in case of using weak magnetizable metals in that one metals with lower hysteresis losses selects.

Mit Rücksicht auf etwaige Stromverluste kann es vorteilhaft sein, daß das Material außer den genannten Eigenschaften niedrige elektrische Leitfähigkeit besitzt. Ferner kann man zwecks Herbeiführung einer weiteren Verminderung der Verluste für den Fall, daß für den Tragkörper schwach magnetisierbares Metall verwendet werden soll, den Tragkörper in gegeneinander isolierte Drähte unterteilen.Taking into account any power losses, it can be advantageous to that the material has, in addition to the properties mentioned, low electrical conductivity owns. Furthermore, in order to bring about a further reduction in losses in the event that weakly magnetizable metal are used for the support body is to divide the support body into mutually insulated wires.
