Description
Technical field
The invention belongs to electric armour clamp technical field, more particularly, to a kind of damper hung on power transmission line.
Background technology
The power transmission line that high-altitude is set up is because the influence of aerial air-flow easily triggers mechanical oscillation phenomenon, and mechanical oscillation are with gentle breeze
Cause the oscillation phenomenon of generation the most frequent, when wind speed is relatively low, when wind laterally blows over power transmission line, meeting forms stable in its behind
The Von Karman vortices fallen, make power transmission line that the aeolian vibration of high-frequency, short arc occur, it is disconnected that this vibration can cause wire that fatigue occurs
Stock, serious meeting cause line-outage contingency, threaten the service life of overhead transmission line.
To solve the above problems, suppressing the aeolian vibration of wire usually using damper, the use of damper can have
Effect reduces wire amplitude and maximum dynamic bending strain, improves that power transmission line is safe for operation and service life.In general damper is for example
Vibrationproof disclosed in CN201320394073.4, CN201020566410.X, CN201420327082.6, CN201220418825.1
Hammer, is made up of suspension arrangement, steel strand wires, weight three parts, and suspension arrangement is used to connect steel strand wires, tup and power transmission line and will prevented
Vibration hammer is fixed on power transmission line, and steel strand wires are used to connect tup and play a part of power consumption, and tup is used to coordinate power transmission line gentle breeze
The frequency of vibration, to reduce aeolian vibration amplitude.
But further study show that, problems be present in above-mentioned existing damper:When in use, due to
Suspension arrangement smoother, damper would generally occur play along wire and deviate initial position, reduce vibration-isolating effect, together
When, the wire clamp held can make wire produce stress concentration, cause the wire in wire clamp exit easily to wear;Second, steel strand wires
Power consumption effect is limited;Third, wire is when occurring aeolian vibration, it is not planar to move completely, it also occur that out-of-plane
Vibration, therefore the actual vibration track of wire is ellipse, multiple tups of existing damper are in the same plane to be difficult to press down
The vibration of plane outer conductor processed, although two tup locus angles stagger in CN201020566410.X, its vibrationproof frequency
Rate scope is still smaller, and one end that tup is connected with steel strand wires is spherical, and it processes inconvenience, and insecure, appearance is connected with steel strand wires
Easily loosen.
The content of the invention
For the disadvantages described above or Improvement requirement of prior art, the invention provides a kind of vibrationproof hung on power transmission line
