Description
Technical field
The utility model relates to a kind of anti-dancing device of overhead transmission line bundle conductor.
Background technology
For overhead transmission line how anti-dance, current domestic existing thinking generally comprises following mode:
(1) suppress to wave by changing wire characteristic, most anti-dance device belongs to this type of, comprises detuning pendulum, suppresses torsional oscillation type anti-dance device, two parallel wielded-proof device, integral eccentric weight etc.;
(2) object suppressing to wave is reached, as air flow spoiler by upsetting along shelves air-flow;
(3) being reached the object suppressing to wave by various ice-covering-proof measure, as adopted low curie point alloy material, using snow defence wire and great current deicing etc.;
(4) inter-phase spacer is installed on two phase conductors and suppresses alternate waving.
Wherein (1), (2) two kinds of modes do not have the alternate function of waving of suppression, (3) technology is not mature enough, and realizing has certain difficulty, and (4) can realize suppressing alternate waving, but complicated structure, installation procedure is more difficult.
Utility model content
Technical problem to be solved in the utility model is just to provide the anti-dancing device of a kind of overhead transmission line, and can effectively suppress the vertical of coated by ice of overhead power transmission line wire and level to be waved, structure is simple, simple installation.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: the anti-dancing device of a kind of overhead transmission line, overhead transmission line is hung by insulator and is arranged on transmission tower, conductor spacer is provided with between each wire of overhead transmission line, described conductor spacer is connected with wire by wire clamp, spring damping and vibration isolating device is connected with below described conductor spacer, described spring damping and vibration isolating device comprises at least one group of spring damping and vibration isolating assembly, described spring damping and vibration isolating assembly comprises cylinder, described cylinder is built with anti-icing fluid, damping spring, steel ball, described damping spring is connected with steel ball.
Preferably, described spring damping and vibration isolating device is provided with three groups of spring damping and vibration isolating assemblies, the end to end composition triangular structure of described three groups of spring damping and vibration isolating assemblies.
Preferably, the rectangular frame structure of described conductor spacer, four wires are connected to the corner of conductor spacer by wire clamp.
The utility model by installing the anti-dancing device with ballast, vibration damping on bundle conductor, the anti-dancing device of this vibration damping forms triangular structure by three spring damping quality systems, each spring damping quality system is made up of and closed at both ends steel ball, spring and anti-icing fluid, when waving generation, realized vertically by three spring damping quality systems and horizontal direction wave energy dissipation, suppress or weaken to wave.
