The first above-mentioned stockbridge damper, the second stockbridge damper, the 3rd stockbridge damper are identical with the structure of the 4th stockbridge damper.
The structure of the first above-mentioned stockbridge damper, the second stockbridge damper, the 3rd stockbridge damper and the 4th stockbridge damper is as follows: it comprises tup, steel strand wire and wire clamp clamping plate, a Compress Spring is provided with between steel strand wire and a tup, wherein tup is by the cast iron cylinder being positioned at core, and the blade of design outside cylinder is formed, be provided with the gap of 3-5 millimeter between adjacent blades, the profile that blade constitutes tup is Pear-Shaped.
Owing to adopting technique scheme, the utility model tool is had the following advantages and effect:
Four stockbridge dampers are arranged on the adjacent wire of two levels by the utility model, after being connected by spring, conductor vibration energy can better be absorbed, after the two groups of stockbridge dampers be arranged on a wire are installed at a certain distance, be connected with the stockbridge damper of on adjacent wires by damping spring, effective by the vibration energy absorption on wire, and change circuit wobble frequency, prevent the vibration of circuit and wave.Better consumption effectively prevents conductor vibration, and shockproof effect obviously strengthens, and the utility model is not by conductor vibration frequency influence, and various vibration frequency all has good shockproof effect.
The operation principle of stockbridge damper is as follows: the tup of stockbridge damper is designed to Pear-Shaped, and outside is designed to blade construction, like this under the prerequisite not changing tup overall weight, time on the External Force Acting to tup such as wind, rain, snow, hail of external force, gap is provided with between adjacent blades, and be designed to helicoidal structure, reduce the extraneous vibration bending stress of tup self to the impact of wire.Due to the setting of blade and Compress Spring, the inertia action effect of tup is strengthened, further increase the effect that stockbridge damper entirety prevents from vibrating.The arranging of blade can also lay down a part of external force to the downward Action of Gravity Field of tup, can useful life of extension lead and tup.
