Description
Technical field
The present invention relates to transmission line of electricity field, specifically a kind of rotatable damp type conductor spacer.
Background technology
Transmission line of electricity longitudinal direction out-of-balance force is an important design load, and circuit breaking is to produce longitudinal unbalance power
One of factor.Circuit breaking mainly has following several reasons：Fatigue of materials, lightning fusing, icing is waved, foreign object collides, high wind,
Gold utensil abrasion etc..
During broken string, due to releasing the tension force of electric wire suddenly, break point is driven along linearly coupled, and it is rapid distally along wire
Propagate.After broken string, the energy discharged when electric wire is to break makees Nonlinear Free Vibration as initial excitation.Ground according to correlation test
Study carefully conclusion, circuit breaking transient dynamics effect has amplification to wire tension, dynamic tension peak value be initial tension 1.5 ~
2.5 again.
When using regular intervals rod, instant impact during conductor cord disconnection easily causes wire to be extracted out from conductor spacer,
And regular intervals rod is rigid structure, in the case of being fixedly connected at its both ends with wire, conductor spacer can not buffer broken string impact
Power, conductor spacer fracture can be caused when serious, is fallen, easily causes larger security incident.
Based on this, this case application is proposed.
The content of the invention
It is an object of the invention to provide a kind of rotatable damp type conductor spacer, can buffer broken string impulsive force, reduces disconnected
The generation of line accident.
To achieve the above object, the technical solution adopted by the present invention is：Center pull-rod is provided between two terminations to connect；Institute
State and be provided with spring damping structure inside the pull-rod of center, the end face center of its either end is provided with opening, and any termination is stretched by opening
Enter to center pull-rod inside and set with spring damping respective outer side edges；Another termination is rotatable or is fixedly connected on the another of center pull-rod
One end.
The present invention can be further arranged to：The spring damping structure includes stage clip, catch and connecting rod；Connecting rod one end
It is connected with catch, the other end is connected with the termination through opening；Stage clip is located between catch and the termination.
The present invention can be further arranged to：The termination is duckbill termination.
The present invention can be further arranged to：Center pull-rod is forged using aluminum alloy forged technique, and a diameter of 80mm, wall thickness are
6mm。
The present invention can be further arranged to：Stage clip uses stainless steel wire, and transverse elasticity coefficient is 7000kg/mm2。
The present invention can be further arranged to：The pressure spring diameter is 60mm.
The present invention can be further arranged to：Center bar length is 300mm, stage clip length is 250mm.
The present invention can be further arranged to：Nearby winding is enclosed with entirely for the junction and junction of the termination and wire
Tension force preformed armor rods, length are 3.0 meters.
Beneficial effects of the present invention：First, the rotatable damp type conductor spacer main body of the present invention（Center pull-rod）It is interior to use spring
Damping structure, it can be rotatable in broken string moment end, broken string tension force is switched into elastic potential energy, significantly alleviate broken string tension force and shake
Swing effect.2nd, termination and center of the present invention pull-rod can relatively rotate, and termination can be with the relative fortune between sub-conductor during conductor cord disconnection
Move and rotate, its structure power transmission is clear, causes moment of flexure excessive because end can not rotate in broken string so as to solve existing conductor spacer
And the problem of destroying.
3rd, the present invention is in fixing point（Termination and the junction of wire）Full tension force preformed armor rods is wound along outside wire both sides, will
Termination securely fixes with wire, makes wire be difficult to extract out from termination in broken string, reduces broken string and falls length.

Embodiment
To be easy to understand the technical means, the inventive features, the objects and the advantages of the present invention, with reference to
Embodiment, the present invention is expanded on further.
Embodiment 1
Rotatable damp type conductor spacer 2, including the termination 1 of the duckbill for being connected with wire 1, termination 2 26 and connection
Termination 1, the center pull-rod 25 of termination 2 26.Center pull-rod 25 is hollow cylinder closed at both ends, the end face center of its upper end
Provided with opening, termination 1 stretches to the inside of center pull-rod 25 by opening and is connected with intermediate connector 22.Intermediate connector
22 be the nunchakus body with certain length, and its other end is connected with catch 24, and catch 24 is slightly less than opening and can be in center pull-rod 25
It is interior freely to rotate.Catch 24 and center pull-rod 25 are to be provided with stage clip 23 between that upper end end face.Be preferably such that catch 24 with
End face keeping parallelism, so as to the uniform force of stage clip 23 positioned there between.Termination 2 26 is fixedly connected on center pull-rod 25
Other end end face on.
To make rotatable damp type conductor spacer 2 have certain tensile strength, stage clip 23 uses stainless steel in the present embodiment
Silk, transverse elasticity coefficient is 7000kg/mm2。
Center pull-rod 25 is forged using aluminum alloy forged technique, a diameter of 80mm, wall thickness 6mm, length 300mm.Phase
Adapt to, 23 a diameter of 60mm of stage clip, the length of stage clip 23 is 250mm.
To reinforce the connection between termination 1 and termination 2 26 and wire 1, when avoiding the wire 1 from being broken from termination 1 or
In termination 2 26 extract out tenesmus influence All other routes, termination 1, termination 2 26 with it is equal near the junction and junction of wire 1
It is 3.0 meters of full tension force preformed armor rodses 3 that winding, which is enclosed with length,, also will not be from termination 1 or termination 2 26 even if wire 1 is broken
Extract out, greatly reduce because of accident caused by the fracture tenesmus of wire 1.
