Claims (1)

Die bei Freileitungen auftretenden mechanischen Schwingungen kann man dadurch vermindern, daß man mit der Leitung schwingungsfähige Gebilde verbindet, die durch die Seilschwingungen ebenfalls zu Schwingungen erregt werden und dämpfend auf die Leitungsschwingungen zurückwirken. Die bekannten Dämpfer bestehen aus einem kurzen Stück eines Leitungsseiles, das der zu schützenden Leitung gleich oder ähnlich ist. Das Seilstück ist in seiner Mitte an der Leitung so befestigt, daß die beiden Enden frei schwingen können. Die Enden sind mit Gewichten versehen. Das elastische Glied des Dämpfers wird durch das Seilstück verkörpert. The mechanical vibrations that occur in overhead lines can be avoided in this way reduce the fact that one connects vibratory structures with the line, which by the Cable vibrations are also excited to vibrations and dampen the cable vibrations work back. The known dampers consist of a short piece of cable that is to be protected Line is the same or similar. The piece of rope is in its middle on the line attached so that the two ends can swing freely. The ends are with weights Mistake. The elastic member of the damper is embodied by the piece of rope. Die Anpassung der Elastizität und Dämpfung einer Vorrichtung dieser Art an die Schwingungsverhältnisse der Leitung ist unter Umständen recht schwierig. Die Federkonstante des die Gewichte tragenden Seilstükkes ist nämlich fest gegeben bzw. nur in engen Grenzen veränderbar. Diese Grenzien stimmen häufig nicht mit derjenigen Federung überein, die für die gerade vorliegenden, Verhältnisse am günstigsten ist. Außerdem bildet bei den bekanntem Dämpfern das Seilstück nicht nur die Elastizität des Gebildes, sondern auch dessen Dämpfung, da diese Dämpfung durch die innere Reibung des Seilstückes bestimmt ist. Die Erfindung beruht auf dem Gedanken, das elastische Glied der Dämpferanordnung im Gegensatz zu den bekannten Dampfern nicht aus einem Körper auszubilden, der dem Leitungsseil gleich oder ähnlich ist, sondern dazu, eine besondere Federung zu benutzen, die den jeweils vorliegenden Verhältnissen weitgehend angepaßt werden kann. Erfindungsgemäß wird als elastisches Glied eine Blattfederanordnung verwendet, bei der die Reibung zwischen den einzelnen Federn einstellbar ist.The adaptation of the elasticity and damping of a device of this type to the The vibration conditions of the line can be quite difficult under certain circumstances. The spring constant of the piece of rope carrying the weights is fixed or can only be changed within narrow limits. These borders often do not match the suspension that is used for the Conditions is most favorable. In addition, the piece of rope forms in the known dampers not only the elasticity of the structure, but also its damping, as this damping is caused by the internal friction of the Rope piece is determined. The invention is based on the idea of the elastic member In contrast to the known dampers, the damper arrangement does not consist of one body train that is the same or similar to the line rope, but also a special one To use suspension that largely adapted to the prevailing conditions can be. According to the invention, a leaf spring arrangement is used as the elastic member used in which the friction between the individual springs is adjustable. Auf der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Der Dämpfer besteht aus 'einem Bündel Blattfedern 1, das an beiden Enden mit je einem Gewicht 2 und 3 versehen und in seiner Mitte durdh eine Klemme 4 an der Leitung 5 aufgehängt ist. Treten Seilschwingungen in der Leitung 5 auf, so werden die Massen 2 und 3 zu freien Schwingungen erregt. Dabei reiben die einzelnen Lagen des Blattfederbündels aneinander und erzeugen eine Reibung, die einen Teil der Schwingungsenergie in Wärme umsetzt und dadurch wirkungslos macht.An exemplary embodiment of the invention is shown in the drawing. The damper consists of 'a bundle of leaf springs 1, the provided with a weight 2 and 3 at both ends and durdh in its middle a clamp 4 is suspended from the line 5. If rope vibrations occur in the line 5 on, the masses 2 and 3 are excited to free oscillations. In doing so, the individuals rub Laying of the leaf spring bundle against each other and create a friction that one Converts part of the vibration energy into heat and thus makes it ineffective. Die Einzelblätter des Federbündels sind von je einem Klemmbügel 6 und 7 umgeben, durch die mit Hilfe von Stellschrauben 8 und 9 die Federblätter mehr oder weniger stark aneinandergepreßt werden können. Zweckmäßig werden die Bügel 6 und 7 mit dem obersten Blatt des Federbügels fest verbunden, so daß diese sich nicht verschieben können. Die übrigen Blätter müssen jedoch im Bügel verschiebbar geführt sein. 6gThe individual leaves of the spring bundle are each surrounded by a clamp 6 and 7, by means of adjusting screws 8 and 9 the spring leaves can be pressed together to a greater or lesser extent. Appropriately, the bracket 6 and 7 with firmly connected to the top sheet of the spring clip so that they do not move can. However, the remaining leaves must be slidably guided in the bracket. 6g • Patentanspruch:• Claim: Schwingungsdämpfer für Freileitungen mit einem an der Leitung anzubringenden elastischen stabförmigen Glied und je einer an dessen frei beweglichen Enden befindlichen Masse, dadurch gekennzeichnet, daß das elastische Glied aus 'einem Bündel Blattfedern besteht, deren Reibung gegeneinander einstellbar ist.Vibration damper for overhead lines with one to be attached to the line elastic rod-shaped member and a mass located at each of its freely movable ends, characterized in that, that the elastic member consists of 'a bundle of leaf springs, the friction of which is adjustable against each other.
