Embodiment
As depicted in figs. 1 and 2, overhead transmission line is hung by insulator and is arranged on transmission tower, conductor spacer 2 is provided with between each wire of overhead transmission line, described conductor spacer 2 is connected with wire by wire clamp 21, wire clamp and conductor spacer are rotationally connected, spring damping and vibration isolating device 1 is connected with below described conductor spacer, described spring damping and vibration isolating device comprises at least one group of spring damping and vibration isolating assembly, described spring damping and vibration isolating assembly comprises cylinder 11, cylinder closed at both ends, cylinder is built with anti-icing fluid 12, damping spring 14, steel ball 13, described damping spring 14 is 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 to the corner of conductor spacer 2 by wire clamp 21, cylinder uses steel pipe manufacturing usually, and spring damping and vibration isolating device 1 is installed on conductor spacer 2 lower central place, and conductor spacer 2 is connected with wire by wire clamp 21.As shown in Figure 2, spring damping and vibration isolating device is provided with three groups of spring damping and vibration isolating assemblies, three groups of spring damping and vibration isolating assembly end to end composition triangular form structures.
Damping spring and steel ball not only absorbable guide line and vertical vibrating energy in the process of waving, also Absorbable rod horizontal vibration energy, anti-icing fluid prevents from being bonded together at ice and snow weather damping spring, steel ball and steel pipe, and self there is endergonic function, three such end to end common compositions of spring damping and vibration isolating assembly have the anti-dance system of ballast, vibration damping.
Further, as shown in Figure 3, transmission tower is provided with damper rail 3, described damper rail is provided with difference in height, and the top of described insulator is provided with cushion idler 32, and described damper rail comprises rail groove 31, and described cushion idler 32 is located in rail groove 31.As shown in Figure 4, damper rail is made up of a steel plate extended along its length and the two symmetrically arranged angle steel that are welded and fixed below steel plate.
Cushion idler is connected with shock-absorbing spring simultaneously, when the longitudinal unbalance tension force of overhead power transmission conducting wire occurs, cushion idler 32 slides along damper rail, the longitudinal unbalance tension force of automatic elimination overhead power transmission conducting wire, shock-absorbing spring can offset a part of power, avoids overhead power transmission conducting wire to swing by a relatively large margin.In addition, the top of described insulator is connected with one and hangs screw rod, and described suspension screw rod connects cushion idler by universal joint.
The V-shaped structure of described damper rail (along damper rail bearing of trend), certain damper rail also can be arc-shaped structure, difference in height can be produced equally in the orbital plane of damper rail, when the longitudinal unbalance tension force of overhead power transmission conducting wire occurs, by the balancing out motions longitudinal unbalance tension force of cushion idler along damper rail, and difference in height can be passed through simultaneously, recover initial equilibrium conditions.
When overhead power transmission conducting wire both sides do not have unbalanced tensile force, insulator is in vertical state; When overhead power transmission conducting wire both sides produce unbalanced tensile force due to uneven icing or other reason, insulator starts to offset to tension force larger side; When the longitudinal unbalance tension force of overhead power transmission conducting wire exceedes set point, insulator starts to slide under the effect of unbalanced tensile force along damper rail direction component, the overhead power transmission conducting wire length of insulator both sides changes, and tension force larger side line length increases, and tension force reduces thereupon; Tension force smaller side line length reduces, and tension force increases thereupon, and after the tension force of both sides reaches dynamic equilibrium, insulator restores balance state; When the unbalanced tensile force of insulator both sides reduces or eliminates, under the tension force effect and overhead power transmission conducting wire Gravitative Loads of both sides line length inequality, insulator slides to damper rail minimum point, finally gets back to mid point (bottom V-type) and recovers initial equilibrium conditions.
