Description
Technical field
The utility model belongs to field of electrical equipment, is related to cable shake-proof technology, and in particular to a kind of anti-positioning is adjustable
Stockbridge damper.
Background technology
At present, it is well known that the effect of the meteorological condition such as overhead power line wind-engaging, ice, low temperature, circuit is produced vibration
With dynamic dance.Vibration frequency is higher and amplitude very little, and wind shake is dynamic to make aerial cable at suspension point repeatedly by stubborn folding, causes material tired
Labor, finally result in stranded, line-outage contingency.The frequency waved is very low, and amplitude is very big, it is easy to causes alternate flashover, causes
The major accidents such as line tripping, power failure or burn wire.At present, gentle breeze vibrations are the principal modes of trolley wire vibrations, and
The final commonly-encountered vibrations for most having harm, can seriously cause electric wire to be broken, people is suffered huge economic losses.Stockbridge damper is only
It is an iron leg rod.Because it is carried additionally at circuit tower bar suspension point, with absorption or damping vibration energy, change circuit wobble frequency,
Prevent the vibration of circuit or wave.But because its mounting distance characteristic provides, installation site too far, is given typically apart from electric pole
Install, fasten the next certain difficulty of bolt band that it fixes wire above, it is not easy to operate, leave hidden danger to installation quality.Therefore,
Stockbridge damper is widely used in overhead power line, and the protection to circuit has important security implications.
