Description
Technical field
The present invention relates to a kind of wire shockproof structure, the connection knot of more particularly to a kind of overhead power transmission conducting wire stockbridge damper
Structure.
Background technology
The effect of the meteorological conditions such as overhead power transmission conducting wire wind-engaging, ice, low temperature, makes circuit produce vibration and wave.During vibration
Frequency is higher and amplitude very little, and wind shake is moved makes aerial line repeatedly by stubborn folding at suspension point, causes fatigue of materials, finally results in disconnected
Stock, line-outage contingency.The frequency waved is very low, and amplitude, very greatly it is easy to cause alternate flashover, causes line tripping, power failure
Or the major accidents such as wire of burning.In order to solve this problem, the wire of high-tension overhead line often hangs a hand hammer, this
Plant hand hammer damper, damper sets to reduce conductor vibration.Current stockbridge damper is by wire clamp clamping plate, steel strand wires
Constitute with tup, be arranged on wire.When overhead transmission line produces vibration, stockbridge damper up-down vibration therewith, lazy due to tup
Property effect so that steel strand wires constantly bend up and down, thus damping vibration energy.
But current overhead transmission line is in addition to aeolian vibration, under the vile weathers such as some rain, snow and strong wind, stockbridge damper
External force effect suffered by tup increases, and disengaging situation often so that the use longevity of stockbridge damper between tup and steel strand wires
Life shortens, and safeguards that replacement operation increases.Simultaneously because damper is acted on by external force, the extraneous vibration bending stress of its own
Impact can increase significantly waving of wire, reduces the service life of wire.The effect that damper is significantly waved for reduction wire
Poor.

Shockproof effect.
Shockproof effect of the present invention is good, and on two adjacent transmission pressures, being mounted opposite two groups of present invention just can be effective
The vibration preventing wire, easy to maintenance, greatly reduce the maintenance workload to wire and stockbridge damper.Tried by the present inventor
Test, shockproof effect and conventional stockbridge damper using the present invention are contrasted, the shockproof effect of the present invention is substantially better than existing shockproof
Hammer structure, adopts the present invention can be with the service life of extension lead at least 10 years.
What the tup of the stockbridge damper of the present invention was innovated makes wheel hub, wheel shaft type structure into, and sheathed impeller on wheel shaft, so
On the premise of not changing tup overall weight, when the external force such as the wind of external force, rain, snow, hail are applied on tup, impeller can
To lay down a part of external force, effectively reduce significantly waving of wire, solve the extraneous vibration bending of vibration abatement itself
The impact to wire for the stress.Because the setting of impeller and compression spring is so that the inertia action effect of tup strengthens, further
Improve the effect that stockbridge damper integrally prevents from vibrating.The setting of impeller can also lay down a part of external force gravity downward to tup
Effect, can extension lead and tup further service life.
