Description

Vorrichtung zum Aufhängen elektrischer Freileitungen an Isolatoren mittels gelenkig gelagerter Abspannklemmen Man hat bereits vorgeschlagen, Freileitungen zur Verminderung von Seilschwingungen federnd derart aufzuhängen, daß der Isolatorklöppel unter Zwischenschalten von Schraubenfedern eingesetzt ist. Derartige Anordnungen sind jedoch zur Unterdrückung und zum Dämpfen von Seilschwingungen ungeeignet, .da Schraubenfedern bekanntlich eine sehr geringe Dämpfung haben. Sie nehmen die Belastungsschwankungen zwar elastisch auf, geben sie jedoch mit fast der gleichen Stärke weiter, so daß die Seilschwingungen nicht unterdrückt werden.Device for hanging electrical overhead lines on insulators by means of articulated tensioning clamps It has already been proposed overhead lines to reduce rope vibrations in such a way that the insulator clapper is inserted with the interposition of coil springs. Such arrangements are unsuitable for suppressing and damping rope vibrations, because It is known that coil springs have very little damping. You take the load fluctuations although elastic, they pass on with almost the same strength, so that the rope vibrations are not suppressed.

Man schlug daher vor, in die Gliederketten der Hängeisolatoren bzw. zwischen den Isolatoren und den gelenkig gelagerten Abspannklemmen Elemente aus Holz, Hartgummi und Filz einzuschalten, die den Seilschwingungen Energie entziehen und sie auf diese Weise dämpfen. Mit derartigen Stoffen machte man jedoch keine guten Erfahrungen, da sie mit der Zeit unter dem dauernden Druck der schweren Leitung ihre elastischen und schwingungsdämpfenden Eigenschaften verlieren. Außerdem sind diese Stoffe den atmosphärischen Einflüssen in hohem Maße unterworfen und werden durch die Luftfeuchtigkeit rasch unbrauchbar., Auch die wasserdichte Kapselung dieser Körper und die Durchführung der Tragbolzen mittels Stopfbuchsen durch die Kapselwand vermag die schwingungsdämpfenden Stoffe auf die Dauer nicht genügend gegen Feuchtigkeit zu schützen: Die Stopfbuchsen in den Kapselwänden werden nämlich im Laufe der Zeit durch die dauernden Bewegungen der Gliederkette ausgearbeitet und sind dann naturgemäß nicht mehr wasserdicht.It was therefore suggested that the link chains of the suspension insulators or elements between the insulators and the articulated suspension clamps Switch on wood, hard rubber and felt, which extract energy from the rope vibrations and dampen them that way. But none of these were made with such substances Good experiences, as they are under the constant pressure of heavy management over time lose their elastic and vibration-damping properties. Also are these substances are and are to a great extent subject to atmospheric influences quickly unusable due to the humidity., Also the waterproof encapsulation of this Body and the implementation of the support bolts by means of stuffing boxes through the capsule wall In the long run, the vibration-damping substances are unable to withstand moisture to protect: The stuffing boxes in the capsule walls will become in the course of time elaborated by the constant movements of the link chain and are then natural no longer waterproof.

Diese Übelstände werden gemäß der Erfindung dadurch beseitigt; daß als energieverzehrende Elemente Körper aus kunstharzhaltgen Isolierstoffen verwendet werden,, die in die auch für Traganordnungen nutzbar gemachten, beweglich gelagerten Abspannklemmen eingeschaltet sind. Derartige Körper weisen bei Formänderungen einen sehr hohen Energieverbrauch auf und sind besonders wetterbeständig, so daß keine besonderen Schutzvorrichtungen gegen die Einflüsse der Witterung notwendig sind.These drawbacks are eliminated according to the invention; that bodies made of synthetic resin-containing insulating materials are used as energy-consuming elements are, the movably mounted in the also made usable for support arrangements The suspension clamps are switched on. Such bodies have a shape changes very high energy consumption and are particularly weather-resistant, so no special protective devices against the effects of the weather are necessary.
