Abstract
The utility model relates to a simply connected V-type suspension string which solves the problem that the existing V-type suspension string can not meet the requirements of plus or minus 800kV direct current power transmission lines and comprises two suspension strings with the same structure and presenting in V shape; each suspension string is formed by hanging point hardware fittings, an adjusting plate, a ball head hanging ring, an insulator, a socket hanging plate, a coupling plate and suspension clamps which are connected in sequence; and a grading and shielding ring is arranged on the suspension string. The utility model is characterized in that the coupling plate is a whole plate, the number of the suspension clamps is six and the suspension points of the suspension clamps are respectively distributed at the edge of the coupling plate. The suspension string has the advantages of high strength and light weight, saves steel materials, improves voltage-resistant level and resistance to radio interference and corona discharge, can adapt the voltage-resistant requirements of plus or minus 800kV direct current power transmission lines, is convenient to install and carry and reduces the labor intensity of operators.
Description
Technical field
The utility model belongs to a kind of electric armour clamp, particularly a kind of simply connected V-type string that dangles.
Background technology
The V-type string that dangles is a vitals in the transmission line, bears the wind-force of weight, icing weight and the horizontal direction of vertical direction lead.The existing V-type 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 800KV DC power 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 V-type 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 ± requirement of 800KV DC power transmission line six-multiple conductor.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, the dangle intensity of string of existing V-type can not satisfy ± requirement of 800KV DC power transmission line.
Summary of the invention
The purpose of this utility model is to overcome the existing transmission line V-type problem that voltage withstand class is low, division number is few, intensity is low that string exists of dangling, provide a kind of voltage withstand class height, division quantity is many, intensity the is high simply connected V-type string that dangles, with the specification requirement of satisfied ± 800KV DC power transmission line.
Technical solution of the present utility model is: comprise that two-strip structure is identical and the suspension string of the assembling that is in the shape of the letter V, every is hung string is to be made of the hanging point gold utensil 9 that connects successively, adjustment plate 2, ball-eye 3, insulator 4, socket-clevis eye 5, yoke plate 8, suspension clamp 7, on the suspension string, be provided with and all press shading ring 11, its special character is: described yoke plate 8 is whole plate, and suspension clamp 7 is that the hitch point of six and suspension clamp 7 is distributed on yoke plate 8 edges.
The above-mentioned simply connected V-type string that dangles, the hitch point of suspension clamp 7 is positioned on the same circumference.
The utility model has the advantages that: the intensity height, in light weight, save steel, 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, the requirement of withstand voltage of adaptation ± 800KV DC power transmission line, and be convenient to install and carrying, also reduced labor intensity of operating personnel.
