The harm that few conductor vibration is brought to transmission line of electricity, it is necessary to adopt an effective measure and suppress to it.Current China mainly passes through
The devices such as damping conductor spacer, detuning pendulum are installed to realize its purpose for suppressing conductor vibration, but its effectiveness in vibration suppression is limited.Therefore grind
A kind of obvious conductor spacer of reasonable in design, effectiveness in vibration suppression of hair, is beneficial to the safe operation of transmission line of electricity, reduces maintenance cost.
The content of the invention
It is an object of the invention to provide a kind of energy by collision conductor spacer, the conductor spacer is providing the same of general interval rod function
When, have the effect for reducing transmission line of electricity vibration concurrently.
Above-mentioned purpose of the present invention is realized by following technical solution：A kind of energy by collision conductor spacer, it is characterised in that：Should
Conductor spacer is made up of mass ball, spring, metal hollow ball, metal circular tube, conductor spacer framework, wire clamp and viscoelastic material layer, described
Metal hollow ball is hollow ball structure, surrounding and metal circular tube connecting place opening, and does smooth place with metal circular tube joint
Manage to prevent Spring Card from living；Mass ball, viscoelastic material layer are respectively positioned in the metal hollow ball, wherein, mass ball is located at metal
The center of hollow ball, is suspended state, and point of suspension is located at the center of metal hollow ball；Viscoelastic material layer passes through adhesive
Sticking type is arranged on the inwall of metal hollow ball, so as to play a part of absorbing energy, passive energy dissipation；Spring is located at round metal
In pipe and metal hollow ball, on the central axis in metal circular tube, one end of spring is fixedly connected on conductor spacer framework, separately
One end is connected with mass ball；One end of metal circular tube is connected with metal hollow ball, and the other end is fixedly connected with conductor spacer framework.This
In invention, the material of viscoelastic material layer is preferably rubber, the mass ball, spring, metal hollow ball, metal circular tube,
Every the material of rod framework and wire clamp be preferably steel.
Transmission line of electricity where the energy by collision conductor spacer of the present invention is reduced by the swing and collision process of mass ball
Dynamic respons, solve transmission line of electricity Oscillation Amplitude or frequency problems of too.Compared with prior art, it is characteristic of the invention that：Outside
When portion's environmental load is smaller, is swung by mass ball and realize damping effect；When external environment condition load is larger, mass ball amplitude of fluctuation
Degree increase, collides, viscoelastic material will absorb part in collision process with the viscoelastic material of metal hollow ball inwall
Energy, realizes the effect of power consumption.Because mass ball can be swung in space any direction, and with metal hollow ball inwall viscoelastic
Property material can collide, therefore, such a energy by collision conductor spacer has a multidimensional vibration reduction characteristic, and it is reasonable in design, make letter
Single, it will be widely used in power equipment, transmission line of electricity antivibration area.
