Embodiment Construction

[0009] Referring to Figure 1 , the low-noise wire structure includes a load-carrying core 4 , a conductor 3 , a conductor 2 and a conductor 1 . A conductor 3, a conductor 2, and a conductor 1 are arranged outside the carrying core 4, and the conductor 3 and the conductor 2 are single wires with a circular cross section; the conductor 1 is a single wire with a special-shaped cross section, which is the outermost conductor, and the outermost conductor adopts a trapezoidal cross section aluminum wire strands. In the conductor 1, some single wires with special-shaped cross-sections are higher than other single wires with special-shaped cross-sections, and certain protrusions 5 are formed on the surface of the conductors, and the protrusions have a certain opening angle. As for the height h of the protruding part of the wire is 2.3-2.7mm, the opening angle α of the protruding part is 30°-120°.

[0010] The conductor can be made of duralumin, or rare-earth aluminum alloy, or alumin...

Abstract

A low-noise conducting wire of the invention relates to a special conducting wire used by the overhead transmission line, and the invention is especially suitable for the improving of the new-built extra-high voltage overhead transmission line and the overhead transmission. The structure comprises a bearing core and a conductor. The exterior of the bearing core is arranged with a plurality of layers of conductor. The conductor next to the bearing core is a single wire with a circular cross-section. The outmost layer conductor is a single wire with an odd-shaped cross-section. The outmost layer conductor is provided with single wire of partial odd-shaped cross-sections higher than the single wire of other odd-shaped cross-sections. A projection which is provided with an opening angle is formed on the surface of the conducting wire. The height of the projection formed on the surface of the conducting wire is 2.3-2.7mm, and the opening angle is 30-120degrees. The height of the special-shaped wire fold of the projection at the exterior layer of the low-noise conducting wire is less than the diameter of the current disturbing wire. The artificial operation for winding the current disturbing wire is saved. The invention has the advantages of light weight, convenient construction, reducing the corona sound of the conducting wire and the radio interference level, and effectively preventing the wind noise of the conducting wire.

Description

technical field [0001] The low-noise conductor of the invention relates to a special conductor for overhead power transmission lines, which is suitable for the reconstruction of newly constructed UHV overhead power transmission lines and overhead power transmission lines. Background technique [0002] With the continuous development of large-capacity and ultra-high voltage transmission lines, the wind noise and corona noise brought by the transmission lines and the impact on the environment are becoming more and more serious, and more and more people are paying attention. In the rapid development of transmission lines, especially in the preparatory work of UHV transmission lines, the research on anti-wind noise of wires has become one of the important issues that must be solved in line construction. Contents of the invention [0003] The purpose of the present invention is to provide a low-noise wire, which can reduce the corona sound and radio interference level of the wi...
