Anti-vibration hammer for high-voltage power transmission lines

Abstract

The invention relates to an anti-vibration hammer for high-voltage power transmission lines, in particular for power transmission and distribution lines in power industry, comprising a wire clip, two hammer bodies, a steel stranded wire and at least one pre-stranded wire, wherein the wire clip is fixedly connected with the steel stranded wire and is in the form of a sea horse-shaped structure; the two hammer bodies are in the form of a dumbbell-shaped structure and are symmetrically, obliquely and fixedly arranged on both ends of the steel stranded wire; and the connecting positions of the steel stranded wire and the hammer bodies are arranged on the side surfaces of hammer head at the fixed ends of the hammer bodies. Because partitioning nails are arranged on the wire clip and the pre-stranded wires are respectively arranged on the wire clip at intervals, the anti-vibration hammer and a power transmission cable are effectively connected; because the two hammer bodies are symmetrically and obliquely fixed on both ends of the steel stranded wire, the anti-vibration hammer absorbs different-frequency vibration to prolong the surface life of the lines; because the hammer bodies are designed into a dumbbell shape and windward surfaces are arranged on the hammer heads at the cantilever ends, the anti-vibration hammer has better vibration reduction effect, improves corona voltage and reduces marginal discharge; and because the circular-arc smoothing treatment is carried out on the surfaces of the hammer bodies, the anti-vibration hammer improves the integral performance and reduces pollution flashover.

Description

technical field [0001] The invention relates to an anti-vibration device for transmission and distribution lines in the electric power industry, in particular to an anti-vibration hammer for ultra-high voltage transmission lines. Background technique [0002] After retrieving relevant patent documents, an anti-vibration hammer for high-voltage transmission lines with the same structure as the present invention has not yet been retrieved. As a vibration damping device for transmission and distribution lines, the anti-vibration hammer has been widely used in overhead transmission lines. Due to its structure, the existing anti-vibration hammer has a bulky shape, and it is difficult to eliminate the deposition of water and ice. At the same time, it is easy to produce tip discharge and flash pollution under ultra-high voltage conditions. The ZL200720039659.3 applied by the patentee is named: anti-slip type anti-vibration hammer, which has greatly improved the anti-vibration effe...
