Embodiment
As depicted in figs. 1 and 2, overhead transmission line is arranged on transmission tower by insulator suspension, overhead transmission line
Conductor spacer 2 is provided between each wire on road, the conductor spacer 2 is connected by wire clamp 21 with wire, and wire clamp rotates with conductor spacer to be connected
Connect, be connected with spring damping and vibration isolating device 1 below the conductor spacer, the spring damping and vibration isolating device includes at least one set of spring
Damping vibration attenuation component, the spring damping and vibration isolating component include cylinder 11, and cylinder is closed at both ends, cylinder built with anti-icing fluid 12,
Damping spring 14, steel ball 13, the damping spring 14 are connected with steel ball 13.
Specific to the present embodiment, as shown in figure 1, the rectangular frame structure of conductor spacer 2, four wires are connected by wire clamp 21
In the corner of conductor spacer 2, cylinder generally uses steel pipe manufacturing, and spring damping and vibration isolating device 1 is installed on the centrally under of conductor spacer 2,
Conductor spacer 2 is connected by wire clamp 21 with wire.As shown in Fig. 2 spring damping and vibration isolating device is provided with three groups of spring damping and vibration isolating groups
Part, the end to end composition triangular form structure of three groups of spring damping and vibration isolating components.
Damping spring and steel ball not only absorbable guide line and vertical vibrating energy during waving, also absorbable level
Vibrational energy, anti-icing fluid prevent from being bonded together in ice and snow weather damping spring, steel ball and steel pipe, and itself have and absorb energy
Function, the end to end anti-dance system collectively constituted with ballast, vibration damping of three such spring damping and vibration isolating components.
Further, as shown in figure 3, being provided with damper rail 3 on transmission tower, the damper rail is provided with difference in height,
The top of the insulator is provided with cushion idler 32, and the damper rail includes rail groove 31, and the cushion idler 32 is located at rail
In road groove 31.As shown in figure 4, damper rail is by a steel plate extended along its length and two couple being welded and fixed below steel plate
Claim the angle steel composition set.
Cushion idler is connected with shock-absorbing spring simultaneously, when the longitudinal unbalance tension force of overhead power transmission conducting wire occurs, vibration damping
Roller 32 slides along damper rail, and the automatic longitudinal unbalance tension force for eliminating overhead power transmission conducting wire, shock-absorbing spring can offset one
Part power, avoids overhead power transmission conducting wire from swinging by a relatively large margin.In addition, the top of the insulator is connected with a suspension screw rod,
The suspension screw rod connects cushion idler by universal joint.
The V-shaped structure of damper rail (along damper rail bearing of trend), certain damper rail can also be in circular arc
Structure, equally difference in height can be produced in the orbital plane of damper rail, gone out in the longitudinal unbalance tension force of overhead power transmission conducting wire
Now, by balancing out motions longitudinal unbalance tension force of the cushion idler along damper rail, and simultaneously can be extensive by difference in height
Multiple initial equilibrium conditionses.
When overhead power transmission conducting wire both sides do not have unbalanced tensile force, insulator is in vertical state；Work as overhead power transmission conducting wire
When both sides are due to uneven icing or other reasons generation unbalanced tensile force, insulator starts to offset to tension force larger side；Work as frame
When the longitudinal unbalance tension force of empty transmission pressure exceedes setting value, insulator is in unbalanced tensile force along damper rail direction component
Start to slide under effect, the overhead power transmission conducting wire length of insulator both sides changes, tension force larger side line length increase, tension force with
Reduction；Tension force smaller side line length is reduced, and tension force increases therewith, and after the tension force of both sides reaches dynamic equilibrium, insulator recovers
Poised state；When the unbalanced tensile force of insulator both sides is reduced or eliminated, the uneven tension force effect of line length and aerial in both sides
Under transmission pressure Gravitative Loads, insulator slides to damper rail minimum point, is eventually returned to midpoint (V-type bottom) and recovers initial flat
Weighing apparatus state.
