Description
Technical field
The present invention relates to the duplex-joint V-shaped insulator string that power circuit insulator hardware string, particularly UHV transmission line adopt single hanging point mode.
Background technology
There is following weakness in the V-arrangement overhanging golden tool string of existing transmission line, and one is owing to adopt the double hanging point mode, under inhomogeneous icing situation, after being offset along line, the V string can have a unloading situation, be unfavorable for safe operation, and when deicing jump, insulator can block; Its two, whole grading ring structure is not easy to the gold utensil string and installs, and sustains damage in work progress easily; Its three, the six-multiple conductor yoke plate is split type, has the end of a thread and yoke plate collision problem under the strong wind operating mode; Its four, do not have the long function of adjusting of string, can not fine satisfied actual stringing needs.
Summary of the invention
The purpose of this invention is to provide and a kind ofly adopt the double hanging point mode, be convenient to the duplex-joint V-shaped suspended insulator chain for ultrahigh voltage transmission line that on-the-spot installation, the end of a thread and yoke plate can not collide.
The object of the present invention is achieved like this: a kind of duplex-joint V-shaped suspended insulator chain for ultrahigh voltage transmission line, comprise synthetic insulator, the hanging point gold utensil, the outstanding yoke plate upper edge of six divisions is same to be evenly distributed in six wire clamp holes, and the outside of place, six wire clamp holes circle has two connecting holes on this yoke plate, be connected with a right angle link plate on each connecting hole, this right angle link plate connects one two yoke plate again, two Kong Shangjun of two yoke plates are connected with the identical gold utensil insulator string of structure: the socket-clevis eye lower hinge is on the hole of two yoke plates, socket-clevis eye top is fixed on composite insulation substring one end, the grading ring that is positioned at composite insulation substring one end is fixed on two yoke plates, the insulator string other end connects firmly ball-eye, ball-eye articulates the second U-shaped link again, the second U-shaped link is fixed on the hole of adjusting plate, adjust on the plate other end and connect firmly the first U-shaped link, the first U-shaped link is connected with the hanging point gold utensil.
Above-mentioned six distances that divide 1 connecting hole wire clamp hole immediate with it of the yoke plate that dangles equal the distance in another connecting hole wire clamp immediate with it hole.
The above-mentioned first U-shaped link and adjust also be connected with between the plate two have a round eye on it adjust plate as the bar shaped of transferring length.
Compared to existing technology, the present invention has following characteristics and advantage:
1, duplex V-type overhanging golden tool string of the present invention adopts single hanging point form.Compare the employing double hanging point, under inhomogeneous icing situation, can have a unloading situation after the V string is offset along line, be unfavorable for safe operation.And when deicing jump, insulator can block.Therefore the limb duplex insulator with the V string is designed to single hanging point mode, the lower end is connected with bundle conductor link plate (promptly six divide the yoke plate that dangles) with a right angle link plate by two yoke plates, be equivalent to duplex and close as a wholely, can avoid the generation of problem under the heavy icing area situation.
2, two V string grading rings adopt split type.After electric pressure improves, grading ring main ring pipe size increases, simultaneously, because the connection spacing strengthens, the contour structures of traditional relatively grading ring significantly increases, for ease of installing, guarantee that the aluminum grading ring is not subjected to the damage of work progress, guarantee that self anticorona performance is unaffected, with respect to traditional monolithic construction form, this design is designed to the split formula with two V string grading rings, can solve grading ring like this can be after insulator string installs, install at last, guarantee that its main ring tube-surface quality is unaffected, finish its electrical protection function.
3, the six division yoke plates that dangle adopt overall structure, and lead is packed into behind the suspension clamp, hangs on this yoke plate, finishes suspension insulator guiding and supporting lead.Because six division yoke plates adopt integral types, can effectively guarantee the relative position of six roots of sensation sub-conductor with respect to composite type, and the gold utensil part is few, simple in structure, when design, considered deflection emphatically at strong wind operating mode lower wire, this yoke plate structure can guarantee 50 ° of lead rotations, and wire clamp does not bump yoke plate.With respect to 30 ° of anglecs of rotation of circuit in the past, had significantly to promote.
4, V goes here and there and is provided with the adjustment plate on two limbs, can effectively adjust the length of two limbs.
