Abstract

The utility model discloses a pre-fabricated aluminum pipe jumper. The jumper is realized by two parallel aluminum pipes with evenly arranged suspending spacing rods between the two aluminum pipes, a heavy hammer which is composed of a plurality of suspended hammer pieces and is arranged at the both sides of the symmetrical spacing rods, and a two for one wire clip through a T-shaped wire clip at the end of each aluminum pipe. Compared with the prior art, the looseness of the jumper can be released, the safe operation of the electric system can be guaranteed, the sizes of a tower head can be effectively reduced, and the height of the tower can be reduced. The stability of the jumper is improved and alternating stress at the root of the tension resistance wire clip is reduced to reduce the creep fatigue. Meanwhile, the jumper reduces the floor area, green land destruction and mountain loss for protecting living environment for a human. The utility model has the advantages of simple structure, easy manufacturing and construction, prefabrication, complete fixing after completion, increased installation rate, reduced labor strength at high places, etc.

Description

The prefabricating aluminum pipe wire jumper

Technical field: the utility model relates to the drainage bridle wire apparatus of strained angled tower in a kind of 550KV ultra-high-tension power transmission line.

Background technology: in electric power system 550KV ultra-high-tension power transmission line, the drainage wire jumper of strained angled tower is directly connected to the reliability service of wire insulation suspension system, thereby is very important member.The drainage wire jumper of Shi Yonging was freely to hang wire jumper in the past, promptly used the quadripartion wire jumper identical with wire type, made its natural moulding in construction.Because this wire jumper sag sag is big, when carrying, can not guarantee necessary gap than strong wind, particularly extremely complicated at the situation compacted under that engineered paths is long, gradation for surface pollution is high relatively, insulator string is long, certainly will cause the shaft tower tower head excessive.Not only increase floor space, and improved project cost widely.

Summary of the invention: the utility model is how to reduce the sag that has strained angled tower drainage wire jumper now and guarantee the problem in gap in order to solve, thereby guarantees the safe operation of electric power system.Meanwhile the tower head size be can reduce effectively, iron tower height, floor space and project cost reduced.

Scheme of the present utility model is as described below: this utility model comprises that suspension conductor spacer, T molded lines folder, two become a wire clamp, bolt, also comprise aluminum pipe and suspending hammer sheet, it is by two parallel aluminum pipes and establishes the suspension conductor spacer of sparing cloth between two aluminum pipe, the weight of being made up of a plurality of suspending hammer sheets is established in both sides at the suspension conductor spacer of symmetry, and connects one two in the end of every aluminum pipe through T molded lines folder and become that a wire clamp realizes.

The beneficial effects of the utility model: this utility model is owing to taked two parallel aluminum pipes to replace the drainage wire jumper and be equipped with weight to become the frame mode that a wire clamp is connected with two, compared with prior art eliminated wire jumper degree of speeding substantially, guaranteed necessary gap, avoided line flashover, reduced the tower head size effectively, reduced the iron tower height, not only realized goal of the invention reliably, and owing to increased the vertical component of wire jumper system, restriction condition such as insulator in addition, can improve the stability of wire jumper and reduce the alternate stress of strain clamp root, reduce its creep fatigue.From social benefit, the reduction tower height can suitably reduce the iron tower root to be opened, and reduces floor space, has also reduced greenery patches destruction and massif simultaneously and has run off.Help the protection of environment for human survival.Of the present utility model be also advantageous in that simple in structure, be easy to manufacturing, easy construction, can assemble in advance, moulding is completely fixed, and can effectively improve installation rate, alleviates workman's work high above the ground labour intensity or the like conscientiously.

Description of drawings:

Fig. 1 is the overall structure front view of prefabricating aluminum pipe wire jumper;

Fig. 2 is the overall structure vertical view of prefabricating aluminum pipe wire jumper.

Embodiment: by prefabricating aluminum pipe wire jumper shown in Figure 1 is to be provided with by two parallel aluminum pipes 1 to replace drainage thread, promptly replace flexible conductor by hard lead, being evenly distributed with 2-3 two suspension conductor spacers 2 between two aluminum pipes 1 divides at interval, be provided with in addition counterweight of weight that a plurality of suspending hammer sheets that bolt 3 connects form 4 in the both sides of the suspension conductor spacer 2 of symmetry, and be connected and fixed one two at the two ends of every aluminum pipe 1 respectively through T molded lines folder 5 and become that a wire clamp 6 constitutes.This aluminum pipe wire jumper can be used for strained angled tower in around jumping wire jumper, the inboard wire jumper of corner and corner outside wire jumper, thereby with a wide range of applications.During installation, should will be electrically connected with one section short electric wire between aluminum pipe 1 and the drainage thread, all bolts must not exceed parts, and two changes, one wire clamp, 6 both sides bolts should be worn by the outside and prevent to produce the corona consumed energy to the inside.The utility model is steadily suspended in midair, and the suspension conductor spacer 2 on the aluminum pipe wire jumper is connected with the socket-clevis eye of wire jumper string lower end gets final product at last.This utility model has all been received well-content effect through a large amount of simulation and field experiment.

Claims

1, a kind of prefabricating aluminum pipe wire jumper, comprise and hang conductor spacer (2), T molded lines folder (5) two change one wire clamps (6), bolt (3), also comprise aluminum pipe (1) and suspending hammer sheet, it is characterized in that: it is by parallel two aluminum pipes (1) and establishes even being furnished with and hang conductor spacer (2) between two aluminum pipes (1), the weight of being made up of a plurality of suspending hammer sheets (4) is established in both sides at the suspension conductor spacer (2) of symmetry, and connects one two in the end of every aluminum pipe through T molded lines folder (5) and become a wire clamp (6) and constitute.
