Background technology
Electric armour clamp will stand to ice on the transmission line of long-time running, the baptism of snow, storm, strong wind, sleet, icing easily cause the faults such as wire ice-shedding, phase fault, wire collision lightning conducter, so electric armour clamp must possess higher mechanical strength and enough coefficient of safetys.Suspension string is the important gold utensil in the transmission line, bear the wind-force on weight, icing weight and the horizontal direction of vertical direction wire, the junction flexibility of insulator string two ends and gold utensil is bad in the suspension string of existing ± 500kV transmission line, rotation is dumb, can affect the reliability of connection during conductor vibration.
Summary of the invention
That the utility model provides is a kind of ± and 500kV common-tower double-return circuit is with double hanging point single lug duplex V-type composite insulation substring, and make the upper/lower terminal of insulator string form soft chain with gold utensil and be connected.
For achieving the above object, the utility model is taked following technical scheme:
± 500kV common-tower double-return circuit double hanging point single lug duplex V-type composite insulation substring, comprise two groups of V-shaped suspension insulators, every group of suspension insulator is comprised of the insulator string of two parallel connections, one end of every insulator string of every group of suspension insulator connects UL shape link successively, the DB type is adjusted plate, U-shaped link and EB hardware, the other end is connected with same yoke plate by UL shape link, yoke plate is connected with the quadripartion hanging yoke plate by the right angle link plate, at yoke plate grading ring is installed, at the quadripartion hanging yoke plate suspension clamp is installed.
As light ice formation wire suspension string, adopt EB hardware formation double hanging point and shaft tower to link, the DB type is adjusted the length of every group of suspension insulator of plate capable of regulating.Every insulator string of every group of suspension insulator all is comprised of synthetic insulator, and the oval ring of the synthetic insulator at every insulator string two ends all is ring-ring connecting hinge contact with UL shape link, has formed flexible soft chain, make rotate flexibly, connect reliable.
Technique scheme can also be done following improvement: hanging yoke plate can install heavy punch piece additional as required, also is provided with the preformed lines that protect in the wire folder hole of suspension clamp.
The connection at the utility model insulator string two ends is reliable, rotation is flexible, and operation is all safe and reliable under various operating modes.
