Abstract
The utility model provides a conductor for an overhead power transmission line, wherein the surface of the conductor is wound with current disturbing wires in a diagonal manner. The conductor can effectively reduce the level of wind noises and corona noises of the conductor of a power transmission line. Meanwhile, the conductor can also reduce the influence of the power transmission line on the ambient environment.
Description
Technical field
The utility model relates to a kind of conductor wire, belongs to the power transmission and transformation field.Be a kind of lead that is used for overhead transmission line specifically.
Background technology
Electric power often needs to adopt overhead transmission line in the process of transporting, and the transporting in the process of high-tension electricity, around overhead transmission line, can produce wind noise and corona noise, and this transmission line usually can cause noise problem through the residence.
The lead wind noise generally is meant the insufferable sound of people's ear that natural wind acts on the lead to be produced.The vibration frequency of wind noise is roughly 50～250Hz, belongs to the low-frequency range of sound.The lead wind noise has stronger penetration power, along with the increase decay of space length is slower, therefore can propagate into place far away, generally can reach 1000m.Because the supertension line transmission line capability is big, conductor cross-section is big, and division number is many, and iron tower is high, and the probability that lead produces wind noise increases; And sometimes, high-tension line often will be through densely populated areas; General civil buildings acoustic material can only prevent high-frequency noise, is difficult to isolate low-frequency noise, and resident's complaint is increasing; The wind noise problem becomes and is on the rise, and has caused the attention of relevant department.Begin immediately the mechanism of transmission pressure wind noise and the method for control thereof are studied, people have had understanding comparatively clearly to the transmission pressure wind noise gradually.
In general, the lead wind noise has following characteristics:
(1) perhaps crosses over the almost rectangular transmission line of area, mountain valley, wind direction and lead through the open ground, wind noise takes place easily;
When (2) blowed high wind winter, wind noise took place easily;
(3) wind noise takes place in heavy in section, multiple fission conductor easily;
(4) the lead wind noise is similar to the low frequency that jet plane sends and " shouts " sound, and is different with the high-frequency sound that iron tower parts, insulator produce.
Therefore, a kind of overhead transmission line conductor ten minutes necessity that can reduce transmission line wire wind noise and corona noise level is set.
The utility model content
The technical problem that the utility model will solve is: a kind of lead that is used for overhead transmission line is provided, and it can effectively reduce transmission line wire wind noise and corona noise level.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of lead that is used for overhead transmission line, comprise wire body, and wherein, also be wound with the flow-disturbing line with cornerwise form on the surface of said wire body.
At the described lead that is used for overhead transmission line, be preferably, the quantity of said flow-disturbing line is more than two.
At the described lead that is used for overhead transmission line, be preferably, said flow-disturbing line twines in the face of claiming along the longitudinal axis of wire body.
The described lead that is used for overhead transmission line of the utility model, its surface at wire body also is wound with the flow-disturbing line with cornerwise form.It can effectively reduce transmission line wire wind noise and corona noise level.
Description of drawings
Fig. 1 is the said structural representation that is used for the lead of overhead transmission line of the utility model;
Fig. 2 is said another structural representation that is used for the lead of overhead transmission line of the utility model;
Fig. 3 is the said another structural representation that is used for the lead of overhead transmission line of the utility model.
Embodiment
Below, combine accompanying drawing that the utility model is made more detailed description with embodiment.Present embodiment only is the description to the utility model preferred forms, and the scope to the utility model does not have any restriction.
Embodiment
Like Fig. 1, Fig. 2 and shown in Figure 3, the said lead that is used for overhead transmission line comprises wire body 1 and the flow-disturbing line 2 that twines with cornerwise form on the surface of said wire body 1.
Preferably, the quantity of said flow-disturbing line 2 can be for more than two.Said flow-disturbing line 2 twines in the face of claiming along the longitudinal axis of wire body 1.Can certainly be that folk prescription to being wrapped on the wire body 1 with continuing.
The described lead that is used for overhead transmission line of the utility model, its surface at wire body also is wound with the flow-disturbing line with cornerwise form.It can effectively reduce transmission line wire wind noise and corona noise level.Reduce the influence of transmission line to surrounding environment.
Claims (3)
1. a lead that is used for overhead transmission line comprises wire body, it is characterized in that: the surface at said wire body also is wound with the flow-disturbing line with cornerwise form.
2. the lead that is used for overhead transmission line according to claim 1 is characterized in that: the quantity of said flow-disturbing line is more than two.
3. the lead that is used for overhead transmission line according to claim 1 is characterized in that: said flow-disturbing line twines in the face of claiming along the longitudinal axis of wire body.
