Abstract
The utility model relates to a cross type linkage plate used in the suspended tension insulator string of EHV transmission line, solving the problem of large weight of single piece and small split number of prior linkage plate used in the suspended tension insulator string of electric transmission line. The utility model is provided with a lower linkage plate, characterized in that an upper linkage plate is installed on the lower linkage plate, wherein the upper linkage plate and the lower linkage plate are connected together by a suspension plate, the upper linkage plate is provided with a perpendicular triangle linkage plate, and the upper linkage plate and the lower linkage plate are respectively provided with four open holes of cable cleats. The utility model has the advantages that: by using the split structure and high-strength materials, the strength is increased and the weight is reduced as well, convenient for installation and carrying; the upper and lower linkage plates are connected together by a suspension plate, buffering the torsion of swing caused by wind; the upper linkage plate and the lower linkage plate are respectively provided with four open holes of cable cleats, being able to install eight suspension clamps, the bigger split number adapting to the requirements of eight multiple conductors of 1000 KV EHV transmission network.
Description
Technical field
The utility model belongs to a kind of electric armour clamp, and particularly a kind of UHV transmission line is dangled to go here and there and used cross yoke plate.
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.Yoke plate be transmission line dangle the string in vitals, mainly bear the wind-force of weight, icing weight and the horizontal direction of vertical direction lead.Lead is connected with yoke plate by suspension clamp, guarantees its division radical and spacing by yoke plate.The yoke plate that existing 500KV transmission line dangles in the string can not adapt to the requirement of 1000KV UHV transmission network, and subject matter is: existing yoke plate adopts Q235 to make, and tensile strength is lower, and be integral structure, single-piece weight is bigger, thereby installation and carrying are all very difficult.In addition, existing yoke plate is the quadripartion yoke plate, and the division radical of sub-conductor is four, can only be applicable to conductors on quad bundled, can't adapt to the requirement of 1000KV UHV transmission network eight bundle conductors.
Summary of the invention
The technical problems to be solved in the utility model is, overcomes existing transmission line big, the few problem of division quantity of series connection plate weight of dangling, the cross yoke plate of string that provides that a kind of single-piece weight is little, the many UHV transmission line of division quantity are dangled.
The utility model has a lower linking plate, its special character is, upper connective plate is housed on lower linking plate, links together with link plate between upper connective plate and the lower linking plate, the triangle yoke plate perpendicular with it arranged on upper connective plate, four wire clamp installing holes are arranged respectively on upper connective plate and lower linking plate.
Advantage of the present utility model is:
1, adopts split-type structural, and make, both improved intensity, alleviated weight again, saved steel, and be convenient to install and carrying, also reduced labor intensity of operating personnel of high-strength material.
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.
Description of drawings
Fig. 1 is a structural representation of the present utility model,
Fig. 2 is the left view of Fig. 1.
Embodiment
As shown in drawings, the utility model has a lower linking plate 7, and lower linking plate 7 is a pentagon, and both sides are symmetrical, and described lower linking plate 7 adopts and alleviates design, promptly processes a circular hole 6 in the centre of lower linking plate 7, to reduce windage and weight; Upper connective plate 1 is housed on lower linking plate 7, and upper connective plate 1 is the U font; Be in-line between upper connective plate 1 and the lower linking plate 7 and be connected, promptly upper connective plate 1 is on the same plane with lower linking plate 7, links together with link plate 4 between the first line of a couplet 1 plate and the lower linking plate 7, and adopts bolt 3 fixing, puts the torsion of generation with buffering wind; The triangle yoke plate 2 perpendicular with it arranged on upper connective plate 1, and the string so that the composition duplex is dangled adopts the insertion slot type welding procedure to weld together, to improve its bulk strength between described upper connective plate 1 and the triangle yoke plate 2; Four wire clamp installing holes 5 are arranged respectively on upper connective plate 1 and lower linking plate 7, and wire clamp installing hole 5 has eight, and eight wire clamp installing holes 5 are positioned on the same circumference, and evenly is provided with, to satisfy the spacing requirement of transmission line.
