Abstract
The utility model relates to a multifunctional clearance conductor, a clearance with a certain space is arranged between a load carrying steel core and an aluminium conductor stranded with the outside layer, and the clearance is filled with anticorrosion lubricant. The utility model has the advantages of improving current carrying capacity, reducing sag of the conductor between the towers, reducing air bias, reducing wind resistance, and corrosion protection without increasing the section of the conducting wire; not only the cost of conductor material and erection can be saved, but also the performance can be improved and the service life of the conductor can be lengthened.
Description
Technical field
The utility model belongs to a kind of electric wire, definite a kind of multi-functional gap lead of saying so.
Background technology
Present common gap lead, though can improve ampacity under the condition that does not increase sag, as the clearance type lead that Japanese J-PowerSystems company produces, its shortcoming is that kind is single and function is few, is not suitable for requiring more complicated occasion to use.And corrosion-proof vibration-proof wire, though can reduce conductor vibration, its structure is to coat one deck seamless aluminium tubing between steel strand wire and aluminium stranded conductor, and the production difficulty is big, the technological requirement height.And this corrosion-proof vibration-proof wire seamless aluminium tubing unbalance stress when crooked, the situation of fatigue fracture, poor reliability take place easily.
Summary of the invention
The purpose of this utility model is to provide a kind of multi-functional gap lead.It not only can improve ampacity under the condition that does not increase sag, and can reduce wind dance and windage, prevents corrosion.
The purpose of this utility model is realized by following method:
Between the conductor in the core that carries and the outside, the gap of filling anti corrosion lubricant is arranged.Conductor is used for transmission current.When wire erection uses along with the increase gradually of electric current, the conductor expanded by heating and since its with the carrying core between gapped, and the lubrication of lubricant is arranged, conductor then can slide in carrying core periphery and expand, promptly the frictional force between core and conductor levels off to zero.This moment, the tension force of lead was transferred on the core of carrying fully.The coefficient of linear expansion of integrated wire approaches to carry the coefficient of linear expansion of core, makes the sag increment of lead be reduced to minimum.When lead was waved by wind-force, conductor and core produced collision, with waving that the vibration that reduces integrated wire brings.
Owing to adopted the appeal scheme, make the utility model in use, under the situation that does not increase conductor cross-section,, also can guarantee its tensile strength even increase transmission current.Reduce the sag of lead between the tower bar as far as possible.And reduce wind dance and windage, prevent corrosion.
Below in conjunction with accompanying drawing the utility model is elaborated:
Description of drawings
Accompanying drawing 1, accompanying drawing 2, accompanying drawing 3 are sectional side elevations of three embodiment of the present utility model.
There are conductor 2 and conductor 1 in core 4 outsides in carrying, between core 4 and the conductor 2 certain clearance are arranged, with the filling anti corrosion lubricant.
Accompanying drawing 2 is that the lead periphery is smooth circle, and conductor 1 conductor 2 is the lead embodiment of the single line combination of odd-shaped cross section;
Accompanying drawing 3 is lead embodiment that conductor 1 conductor 2 is the single line combination of circular cross-section;
Embodiment
The gap 3 that the filling anti corrosion lubricant is arranged between the core 4 of conductor 1, conductor 2 and carrying.When wire erection uses along with the increase gradually of electric current, conductor 1, conductor 2 expanded by heating, the frictional force that core 4 and conductor are 2 levels off to zero.This moment, the tension force of lead was transferred on the core 4 of carrying fully.The coefficient of linear expansion of the core 4 that the coefficient of linear expansion of integrated wire approaches to carry makes the sag increment of lead be reduced to minimum.When lead was waved by wind-force, conductor 2 produced collision with core 4, vibrated waving of bringing to reduce integrated wire.Anti corrosion lubricant can prevent core 4 corrosion of external condition to metal material.The lead periphery is that smooth circle can reduce windage.
Claims (5)
1, a kind of multi-functional gap lead is characterized in that between the conductor in the core of carrying and the outside gap of filling anti corrosion lubricant being arranged.
2, multi-functional gap according to claim 1 lead is characterized in that the conductor of single line combination in round cross section and the conductor of odd-shaped cross section single line combination constitute.
3, multi-functional gap according to claim 1 lead is characterized in that the lead periphery is smooth circle, is the single line combination of odd-shaped cross section.
4, multi-functional gap according to claim 1 lead is characterized in that conductor is the single line combination of circular cross-section.
5, multi-functional gap according to claim 1 lead, it is characterized in that conductor can adopt soft aluminium, duralumin, semihard aluminium, rare earth aluminium alloy, aldray, cathode copper, the core of carrying can adopt carbon steel, steel alloy, invar (invar), carbon fiber, carbon fibre composite, organic material, organic composite material.
