Description

A kind of Great span self damping conductor

Technical field

A kind of Great span of the utility model is related to a kind of overhead transmission line large-span conductors with self damping conductor, is applicable In the novel conductive wire for having very big damping action to aeolian vibration.

Background technology

With the continuous development of power industry technologies, the voltage class more and more higher of overhead line conveying electricity, stringing distance is got over More to grow, the section of wire is also increasing, in most cases also to cross over mountain after mountain, and crosses river cross a river.Because wire is to set up It is skyborne, under certain weather conditions（Mainly wind）The motion of small amplitude can be made with high frequency, that is, vibrated.Vibration is very Common, as long as there is beam wind just can.Vibration is very unfavorable to wire, and with increasing for vibration number, wire will be tired, Final stranded damage.Particularly Great span aerial condutor, lead height is high, across the water surface, easily forms uniform layer Wind is flowed, aeolian vibration is extremely serious, and the major technique of large-span conductors vibrationproof scheme is the mechanical energy by consuming wiring system Amount, reduces its aeolian vibration.At present, the vibrationproof scheme that large-span conductors use is that wire adds damping wire and damper scheme, is led Line itself is without damping capacity.

The U of patent CN 203179601 use trapezoidal cable architecture self damping conductor, but large-span conductors use it is high-strength Aluminium-magnesium-slicon alloy wire is spent, using the aluminium alloy wire of trapezium structure, conductive line surfaces are twisted out-of-flatness, and point is easily produced in running End electric discharge.The A of patent CN 105632616 use the damping wire of SZ type structures, but SZ molded line can not form stable support, Just it is collapsed by traction wheel and disk tool post gap after wire stranding, conductor structure is unstable.

The content of the invention

The utility model purpose is directed to the deficiency of above-mentioned prior art, there is provided a kind of Great span self damping conductor, is leading Made improvements in the structure of line in itself, be specifically manufactured a kind of Stability Analysis of Structures, smooth outer surface, can voluntarily consume wind shake, vibration damping effect The very big novel conductive wire of fruit.

A kind of Great span of the utility model is to take following technical scheme to realize with self damping conductor：

A kind of Great span self damping conductor includes the plurality of conductive layers of load cored wire and bag in cored wire periphery, more conductive layers Gap, gap filling lubricant grease are provided between load cored wire and between conductive layer and conductive layer.

The plurality of conductive layers uses the aluminum steel of special-shaped cable architecture, and described abnormally-structured aluminum steel must be configured into cylinder Supporting surface, in order to form gap between conductive layer and load cored wire and between conductive layer and conductive layer.

As further improvement of the utility model, the reinforced-core is zinc-plated using High Strength Steel line, high intensity Aluminium alloy layer steel wire or high intensity aluminum-clad steel wire.

As further improvement of the utility model, the plurality of conductive layers（Internal layer aluminium conductor and outer layer aluminium conductor）Using High-strength aluminium-magnesium-slicon alloy wire.

The cross section of the special-shaped wire structure aluminum steel is c-type, and conductive line surfaces are twisted smooth, and point will not be produced in running End electric discharge, conductor structure are stable.

As further improvement of the utility model, between the aluminum-wire layer and aluminum-wire layer of plurality of conductive layers and aluminum-wire layer is with adding Strong cored wire（Steel core）Between keep 0.3-1.5mm gap, in aluminum-wire layer aluminum steel in cylindrical cross section with retaining layer body and gap Stability.

As further improvement of the utility model, the gap filling lubricant grease having, prevent from rushing caused by vibration Abrasion is hit, has protective effect to steel core layer and aluminum-wire layer.

Beneficial effect：Compared with prior art, its remarkable advantage is the utility model：A kind of Great span of the utility model is used Self damping conductor is reasonable in design, simple in construction, easy to install.The utility model is by by load cored wire（Steel core layer）And aluminium Line layer and aluminum-wire layer are separated with aluminum steel interlayer with gap, when wire is by outside aeolian vibration, due to consolidating for each layer metal Have that frequency is different, the friction of dynamic disturbance and interlayer is produced during vibration, percussion power consumption, plays damping effect.Simultaneously in Great span Using self damping conductor the tension force of wire can be made to be undertaken completely by steel core in circuit, reduce sag and vary with temperature amplitude, subtract Small sag, tower height is reduced, advantageously reduce the cost of power transmission sequence construction.A kind of Great span self damping conductor of the utility model Surface is twisted smooth, will not produce point discharge in running, conductor structure is stable.
