Abstract

The utility model relates to a double suspension string of extra high voltage power transmission line, solving the problems of prior suspension string such as low voltage withstand level, less division quantity, and low strength. The double suspension string comprises a U-shaped link, an adjusting plate, a ball eye, an insulator, a grading and shielding ring, a socket eye, and a suspension clamp, wherein the U-shaped link, the adjusting plate, the ball eye, the insulator and the socket eye are connected with each other to form two identical suspension strings. The utility model is characterized in that a separable combination yoke plate comprising an upper yoke plate and a lower yoke plate is installed on the socket eye, and the upper yoke plate and a lower yoke plate are linearly connected with each other through a hanging plate. Four clamp mounting holes are respectively formed on the upper and lower yoke plates, the suspension clamp is installed on the clamp mounting holes, and the grading and shielding ring is fixed on the upper yoke plate. The utility model has the advantages of high voltage withstand level, high resistance to corona and wireless reference, and large division quantity, and is suitable for octant division wire of extra high voltage power transmission grid (1,000KV).

Description

The UHV transmission line duplex string that dangles
Technical field
The utility model belongs to a kind of electric armour clamp, particularly a kind of UHV transmission line duplex string that dangles.
Background technology
At present, the principal voltage grade of China's electric power transmission network is 500KV, and promptly when the electrical network operate as normal, its voltage withstand class is 500KV.Along with economy and science and technology development, the 500KV electric power transmission network can not adapt to the requirement of China's economic construction, and therefore, building 1000KV UHV transmission network just becomes the vital task that China's power industry faces.The string that dangles is the vitals in the transmission line, bears the wind-force of weight, icing weight and the horizontal direction of vertical direction lead.The existing 500KV transmission line subject matter that string exists of dangling is: 1, voltage withstand class is low, and the voltage withstand class during the electrical network operate as normal only is 500KV, can not satisfy the voltage withstand class requirement of 1000KV UHV transmission line.2, corona and radio interference can only satisfy 500KV voltage, when voltage is higher than 500KV, will produce corona and radio interference.3, the existing string that dangles mainly is applicable to conductors on quad bundled, guarantees that the yoke plate of sub-conductor division radical and spacing is the quadripartion yoke plate, can't adapt to the requirement of 1000KV UHV transmission line eight bundle conductors.4, along with the increase of lead radical and wire diameter, the wind-force of lead deadweight, icing and horizontal direction all increases greatly, and therefore, existing intensity of dangling string can not satisfy the requirement of 1000KV UHV transmission line.
Summary of the invention
The technical problems to be solved in the utility model is, overcome the existing transmission line problems such as the voltage withstand class that string exists is low, division quantity is few, intensity is low of dangling, a kind of voltage withstand class height, the division UHV transmission line duplex that quantity is many, intensity the is high string that dangles is provided.
The utility model comprises U type link, adjust plate, ball-eye, insulator, all press shading ring, socket-clevis eye and suspension clamp, described U type link, adjust plate, ball-eye, insulator, socket-clevis eye interconnects, constitute two identical suspension strings, its special character is, the split type combination yoke plate that is made of upper connective plate and lower linking plate is housed on socket-clevis eye, being in-line between upper connective plate and the lower linking plate is connected, and link together with link plate, four wire clamp installing holes are arranged respectively on upper connective plate and lower linking plate, described suspension clamp is installed on the wire clamp installing hole, all presses shading ring to be fixed on the upper connective plate.
Advantage of the present utility model is:
1, yoke plate adopts split-type structural, and make of high-strength material, both improve intensity, alleviated weight again, saved steel, also increased the area of yoke plate, strengthen the distance between the suspension clamp, thereby improved the ability of voltage withstand class and anti-radio interference and corona, adapted to the requirement of withstand voltage of 1000KV UHV transmission line, and be convenient to install and carrying, also reduced labor intensity of operating personnel.
2, link together with link plate between the upper and lower yoke plate, reduced the resistance of wind, cushioned the torsion that the wind pendulum produces.
3, four wire clamp installing holes are set respectively on upper connective plate and lower linking plate, eight suspension clamps can be installed, division quantity is many, adapts to the requirement of 1000KV UHV transmission network eight bundle conductors.

Embodiment
As shown in drawings, the utility model comprises U type link 1, adjusts plate 2, ball-eye 3, insulator 4, all press shading ring 5, socket-clevis eye 6 and suspension clamp 10, above-mentioned parts are existing structure of the prior art, described U type link 1, adjustment plate 2, ball-eye 3, insulator 4, socket-clevis eye 6 interconnect, constitute two identical suspension strings, article two, hang the parallel assembling of string, every U type link 1 that hangs on the string adopts three, is installed in the both sides of adjusting plate 2 respectively; The split type combination yoke plate that is made of upper connective plate 7 and lower linking plate 9 is housed on socket-clevis eye 6, being in-line between upper connective plate 7 and the lower linking plate 9 is connected, be that upper connective plate 7 is on the same plane with lower linking plate 9, link together with link plate 8 between the first line of a couplet 7 plates and the lower linking plate 9, and the employing bolt, with the torsion of buffering wind pendulum generation; Four wire clamp installing holes are arranged respectively on upper connective plate 7 and lower linking plate 9, and the wire clamp installing hole has eight, and eight wire clamp mounting hole site are on same circumference, and evenly setting, to satisfy the spacing requirement of transmission line; Described suspension clamp 10 is installed on the wire clamp installing hole, all presses shading ring 5 with fixing on the upper connective plate 7.
