Description

Voll- oder Hohlseil für elektrische Kraftübertragung mit Schutz gegen Schnee- und Eislast durch Erwärmung mit elektrischem Strom Das Hauptpatent 456 694 betrifft ein Freileitungsseil, bei dem ein Hilfsleiter als Heizleiten im Seil eingebettet ist. Dieser Hilfsleiter kann nach dem Hauptpatent durch eine Ader des Seiles gebildet werden, die von den übrigen Adern isoliert angeordnet ist. Die Heizung soll in diesem Falle durch einen besonderen Strom, der mit dem Betriebsstrom nicht identisch ist, erfolgen. Es hat sieh jedoch als zweckmäßig erwiesen, in gewissen Fällen die Heizung auch durch den Betriebsstrom unmittelbar vornehmen zu lassen. Da die durch die Freileitung normal übertragene Leistung nur derartige Ströme ergibt, die keine erhebliche Erwärmung des Seiles verursachen, muß zur Erreichung dieses Zweckes der Heizleiterquerschnitt so gewählt werden, daß die gesamte zu übertragende Leistung im Heizleiter eine derartige Stromdichte ergibt, daß eine wirksame Heizung des Leiters eintritt. Nach der vorliegenden Erfindung wird dies dadurch erreicht, daß das Seil durch isolierende Zwischenlagen in einzelne parallele Leitungen, die sich z. B. aus den einzelnen Seillagen zusammensetzen, unterteilt ist. Während der Heizperiode wird natürlich nur ein Teil des Gesamtquerschnittes des Seiles zur Übertragung der Leistung benutzt.Solid or hollow rope for electrical power transmission with protection against Snow and ice load due to heating with electric current The main patent 456 694 relates to an overhead cable in which an auxiliary conductor is embedded in the cable as a heating conductor is. According to the main patent, this auxiliary conductor can be formed by a wire in the rope which is arranged isolated from the other wires. The heater should be in this Trap by a special stream that is not identical to the operating stream, take place. However, it has proven to be useful, in certain cases the heating can also be carried out directly by the operating current. Since the through the overhead line Normally transmitted power only results in currents that do not cause significant heating cause of the rope, the heat conductor cross-section must be used to achieve this purpose be chosen so that the entire power to be transmitted in the heating conductor is such Current density shows that effective heating of the conductor occurs. According to the present Invention this is achieved in that the rope by insulating intermediate layers into individual parallel lines, which z. B. assemble from the individual rope layers, is divided. Of course, only part of the total cross-section is used during the heating season of the rope used to transmit the power.
