Description
Technical field
The invention belongs to electric armour clamp technical field, more particularly, to a kind of damper hanging on power transmission line.
Background technology
The power transmission line that high-altitude sets up easily causes mechanical vibration phenomenon due to the impact of aerial air-flow, and mechanical vibration are with mild wind
Cause the oscillation phenomenon of generation the most frequent, when wind speed is relatively low, when wind laterally blows over power transmission line, stable can be formed behind at it
The Von Karman vortices falling, make power transmission line that altofrequency, the aeolian vibration of short arc to occur, and this vibration can lead to wire to occur fatigue disconnected
Stock, serious meeting causes line-outage contingency, threatens the service life of overhead transmission line.
For solving the above problems, damper is usually used to suppress the aeolian vibration of wire, the use of damper can have
Effect reduces wire amplitude and maximum dynamic bending strain, improves power transmission line and runs safety and service life.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 part, suspension arrangement is used for connecting steel strand wires, tup and power transmission line and preventing
Vibration hammer is fixed on power transmission line, and steel strand wires are used for the effect connecting tup and playing power consumption, and tup is used for coordinating power transmission line mild wind
The frequency of vibration, to reduce aeolian vibration amplitude.
But further study show that, there is problems with above-mentioned existing damper：One is in use, due to
Suspension arrangement smoother, damper would generally occur play to deviate initial position along wire, reduces vibration-isolating effect, with
When, the wire clamp held can make wire produce stress concentration, leads to the wire in wire clamp exit to be susceptible to wear and tear；Two is steel strand wires
Power consumption limited use；Three is wire when there is aeolian vibration, is not planar to move completely, it also occur that out-of-plane
Vibration, therefore the actual vibration track of wire are ellipse, and multiple tups of existing damper are in the same plane to be difficult to press down
The vibration of plane outer conductor processed although in CN201020566410.X two tup locus angles stagger, but its vibrationproof frequency
Rate scope is still less, and one end that tup is connected with steel strand wires is spherical, and its processing inconvenience is connected with steel strand wires insecure, holds
Easily loosening.
