Spring friction damper for suspended conductor - has two-piece conductor clamp for attaching helical spring and inertial weight to conductor

The damper comprises at least on helical spring, at least a portion of the turn of which are close wound and a two piece conductor clamp for attaching the spring to a conductor in spaced relation to it. At least one inertial weight is mounted on or attached to the spring so that the weight can be re...

Summary:The damper comprises at least on helical spring, at least a portion of the turn of which are close wound and a two piece conductor clamp for attaching the spring to a conductor in spaced relation to it. At least one inertial weight is mounted on or attached to the spring so that the weight can be resiliently suspended from the conductor by the spring and attaching. The inertial weight is effective to relatively translate and thereby provide sliding friction between the close wound turns of the spring in a direction perpendicular to the axis of the spring when an associated conductor undergoes vibration above a given magnitude. The weight bends the helical spring such that adjacent close wound turns of the spring separate from and impact against each other. Le dispositif comprend au moins un ressort à enroulement 4, dont au moins une partie des spires sont serrées, un moyen 10 permettant de fixer le ressort au conducteur suspendu 12, et au moins un poids inerte 2 relié au ressort et destiné à être suspendu élastiquement au conducteur par le ressort et par le moyen de fixation, et ayant alors pour effet de donner un mouvement de translation relatif aux spires du ressort et de les faire frotter les unes contre les autres dans une direction perpendiculaire à l'axe longitudinal du ressort lorsque le conducteur subit des vibrations excédant une amplitude donnée.
