Description

Leiter für Hochspannungsfreileitungen zur Verringerung der Koronaverluste Bei Steigerung der Wechselstrom- oder Drehstromspannungen ist es erforderlich, auf die Verringerung der Koronaverluste hinzuwirken. Ein bekanntes Mittel besteht in der künstlichen Verdickung des Leiters. Mit dem Wachsen der Betriebsspannung muß aber der Leiterdurchmesser noch mehr vergrößert werden, was zu einer Vergeudung des teuren Leitungsmetalls wie auch zu einer schädlichen zusätzlichen Belastung der Maste und Leitung führen kann. Man hat daher auch vorgeschlagen, eine Vergrößerung des Leiterdurchmessers dadurch zu bewirken, daß der Leiter mit einer rohrartigen Umhüllung. von entsprechender innerer Weite umgeben wird. Nach der Erfindung kann jede gewünschte Verdickung des Leiters dadurch erzielt werden, daß über das Leitungsseil b volle oder gefalzte Röhre a aus gutleitendem Metallblech, wie Kupfer oder Aluminium, geschoben und durch Tragwände c aus dem gleichen Metalle, die durch ihre Form das Aufschieben auf das Leitungsseil erleichtern, auf dem Seile gestützt werden, so daß das Leitungsseil in der Mitte des Rohrdurchmessets liegt. Um Übergangswiderstände zu vermeiden und eine hohe Festigkeit zu erreichen, werden die Rohre durch Schweißung miteinander verbunden, wobei gleichzeitig die Tragwände c mitverbunden werden können.Conductor for high voltage overhead lines to reduce corona losses When increasing the AC or three-phase voltages, it is necessary to work towards reducing corona losses. A well-known remedy is the artificial thickening of the conductor. As the operating voltage grows, it must but the conductor diameter can be enlarged even more, resulting in waste of the expensive line metal as well as a harmful additional burden who can lead masts and lines. It has therefore also been proposed to enlarge it of the conductor diameter by the fact that the conductor with a tubular Wrapping. is surrounded by a corresponding inner width. According to the invention can any desired thickening of the conductor can be achieved that over the cable b full or folded tube a made of conductive sheet metal, such as copper or aluminum, pushed and supported by supporting walls c made of the same metals that, by their shape, make the Make it easier to slide onto the line rope on which ropes are supported, see above that the cable is in the middle of the pipe diameter. About contact resistance to avoid and to achieve high strength, the pipes are welded connected to each other, at the same time the supporting walls c can also be connected.

Vor den Hänge- und Abspannklemmen e endet das Rohr. Es erhält hier einen nachgiebigen, Artsatz d, der bis zur Klemme reicht und derart federnd nachgibt, daß, .sich das Rohr, den Schwingungen und Wärmeänderungen folgend, ausdehnen oder zusammenziehen kann. jedes Strumpfende trägt einen aufgeschweißten Kabelschuh f. Die zusammengehörigen Kabelschuhe werden sowohl untereinander als auch mit den zugehörigen Hänge- oder Abspannklemmen elektrisch gut leitend und mechanisch fest verbunden. Beispielsweise ist ein Lappen mit Loch an den Klemmen vorgesehen, mit dem die Kabelschuhe durch einen Schraubenbolzen g verbunden werden.The pipe ends in front of the suspension and tensioning clamps e. It gets here a resilient, type set d, which extends to the clamp and so resiliently yields, that, .sich the pipe, following the vibrations and heat changes, expand or can contract. each end of the stocking has a welded-on cable lug f. The associated cable lugs are both with each other and with the associated Suspension or tension clamps have good electrical conductivity and are mechanically firmly connected. For example, a tab with a hole is provided on the terminals with which the cable lugs be connected by a screw bolt g.
