Abstract

The utility model discloses a squirrel cage rigid jumper wire device with high voltage electric transmission circuit, which is provided with a connecting pipe as a shaft, wherein the connecting pipe is fixed with a plurality of lead separating bars and at least one suspension connecting part, the jumper wire of the utility model is made into squirrel cage shape, which not only makes a plurality of drainage jumper wires keep fixed clearance and are of no sag degree when passing the strained tower, but also keeps the location where the jumper wire passes the device of no joint. Compared with prior art, the utility model is capable of significantly decreasing line error, effectively preventing corona and significantly improving stability of the jumper wire, which lowers jumper wire creep deformation and increases electric performance and reliability of electric system. At the same time, the utility model can effectively decrease tower height, properly decrease tower amount, reduce floor area and destroy of grounds, and mountain drain and is good for environment protection. The utility model is also reasonable and simple in structure, convenient in manufacture and employment, capable of being assembled beforehand, of low cost and long service life, economical, practical, of extensive employment range and suitable for popularizing.

Description

Squirrel-cage rigid jumper device

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

Background technology: in power system high tension power line, the drainage wire jumper of strain 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 and freely hung wire jumper in the past, promptly used the many division 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.The patent No. 03251649.5 discloses a kind of prefabricating aluminum pipe wire jumper, 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 constitutes.It can eliminate wire jumper degree of speeding substantially, guarantees the gap of wire jumper necessity, has avoided line flashover, has reduced the tower head size, has reduced the iron tower height, reduces its creep fatigue simultaneously.But because this bridle wire apparatus adopts two to become a wire clamp and connect and have joint, so just increased the fault point of circuit, under the situation of especially high relatively, natural environment relative mistake, easily produced corona at gradation for surface pollution.Directly influence the safe operation of ultra-high-tension power transmission line and even electric power system.

Summary of the invention: the utility model is to solve the sag of strain tower drainage wire jumper and guarantee the problem in gap, particularly existing aluminum pipe wire jumper exists joint to cause the line fault point to increase, and under the situation of, natural environment relative mistake high relatively, easily produce corona at gradation for surface pollution.Directly influence the safe operation of ultra-high-tension power transmission line and even electric power system.

Scheme of the present utility model is as described below: this utility model comprises tube connector, the division of many leads conductor spacer, brace and suspention connector, it is by being axle with the tube connector, is connected and fixed on tube connector that a plurality of many leads division conductor spacers and at least one suspention connector realize.

The beneficial effects of the utility model: this utility model is owing to taked said structure, wire jumper is installed support by this form mouse cage, can not only make many drainage wire jumpers there is no sag and pass through remaining the fixed interval (FI) when the strain tower, and at this device place non junction.Compared with prior art can obviously reduce line fault, effectively prevent the generation of corona, significantly improve the stability of wire jumper, thereby reduce the wire jumper creep fatigue, improve the electric property and the reliability of operation of electric power system.Simultaneously can effectively reduce the iron tower height, suitably reduce the iron tower root and open, reduce floor space, reduce that the greenery patches is destroyed and massif runs off favourable ecological environmental protection.Also have simple and reasonable, make easy to use, assembled formation in advance, easy access maintenance, low life-span of cost are long, not only economy but also practicality, range of application extensively, advantage such as suit to apply.

Description of drawings:

Fig. 1 is the overall structure schematic diagram of squirrel-cage rigid jumper device;

Fig. 2 is the end view of squirrel-cage rigid jumper device.

Embodiment: by Fig. 1, squirrel-cage rigid jumper device shown in Figure 2 is to adopt hollow steel pipe as tube connector 1, and this tube connector 1 can be formed by connecting through flange by multistage as required.Evenly be fixed with a plurality of many lead division conductor spacers 2 on tube connector 1, the brace 3 of each division conductor spacer 2 on bolt and tube connector 1 is fixing.On tube connector 1, also be provided with a suspention connector 4 at least.For improve stability also can be in tube connector 1 counterweight in addition.

During making, earlier multistage tube connector 1 is connected as one through flange, fixedly connected again 3,, make division conductor spacer 2 and tube connector 1 constitute whole then through the many leads divisions of bolt conductor spacer 2.Suspention connector 4 is installed respectively on the symmetric points of tube connector 1.During installation, suspention connector 4 should be connected steady suspention with the strain tower suspension apparatus, grip and get final product and will many wire jumpers directly divide on the conductor spacers 2 with it the wire clamp of correspondence by many leads.

Claims

1. squirrel-cage rigid jumper device, comprise tube connector (1), many leads division conductor spacer (2), brace (3) and suspention connector (4), it is characterized in that: it is to be axle with tube connector (1), is connected and fixed a plurality of many leads division conductor spacers (2) and at least one suspention connector (4) formation on tube connector (1).
