Abstract
The utility model discloses a multiple capacity conducting wire, wherein, the center of the conducting wire is a wire core made of carbon fibers, at least one layer of metal wire with Z-shaped sectionis stranded concentrically on the exterior of the wire core, and the metal wire is either a soft aluminum wire or an aluminum alloy wire. The multiple capacity conducting wire has the following advantages: the coefficient of linear expansion of the carbon fiber wire core is about 1/12 that of an ordinary steel core; the tensile strength of the wire core measures up to 2399MPa; the specific gravity of the wire core is 1/4 that of steel; the conducting wire can function at the temperature of 200 DEG C, and has the advantages of light weight, large strength, high-temperature resistance, low slackness and the like, as compared with the ordinary steel core aluminum strand; with the operating temperature of 200 DEG C, the conducting wire can resist frostiness and snow, thereby preventing accident associated with freezing of circuit in winter; and compared with the ordinary metal wire with round section, the Z-shaped section metal wire concentrically stranded outside the wire core can increase the conducting layer filling rate, thereby improving conductivity.
Description
Technical field
The utility model belongs to the transmission pressure that is applicable to grid, relates in particular to a kind ofly to be made core, made the big capacity high transmission pressure of conductive layer by aluminum or aluminum alloy by carbon fiber.
Background technology
Along with expanding economy, the demand of the energy is also being continued to increase, electric power need be transported to the user and just can be used effectively as the main body of the energy.Flow to the user to more electric power, except building new electrical network, the conveying capacity that improves existing line also is an importance.At present, common high voltage electricity transmission conductive wire is a steel reinforced aluminium conductor, and the operating temperature of this lead is about 70 ℃.According to relevant research conclusion, the sectional area that increases lead can increase its current capacity, and the operating temperature that improves lead besides also can not increase its ability to transmit electricity of raising under the sectional area of wire situation.But the operating temperature that improves lead is also brought some problems, is exactly along with operating temperature increases, and the sag of lead increases, waves radius and becomes big, antivibration ability drop, thereby reduces the useful life of circuit and the fail safe of operation.
Summary of the invention
The purpose of this utility model provides a kind of compound double capacity conductor, can satisfy the needs that transmission pressure moves under higher temperature, thereby improves ability to transmit electricity.
For achieving the above object, the utility model adopts following technical scheme: a kind of compound double capacity conductor, the core of its center for making by carbon fiber, at least one layer cross section is arranged is Z-shaped metal wire to concentric stranding outside core, described metal wire is annealed aluminum wire or aluminium alloy wire.
Be stranded in every layer of outer metal wire of core and comprise six roots of sensation metal wire at least.
Strand is shaped on the double layer of metal line with one heart outside core, and double layer of metal cabling direction difference is respectively clockwise direction and counter clockwise direction.
Strand is shaped on the three-layer metal line with one heart outside core, and the second layer metal line is different with other double layer of metal cabling direction.
Be coated with diaphragm at core.
Adopt the compound double capacity conductor of technique scheme, the coefficient of linear expansion of carbon fiber core is about 1/12 of common steel core, tensile strength can reach 2399MPa, the proportion of core is about 1/4 of steel, can move under 200 ℃ of high temperature, compares with common steel reinforced aluminium conductor, have in light weight, intensity is big, high temperature resistant, advantage such as degree of speeding is low, because the lead working temperature is at 200 ℃, therefore advantage cold-resistant, anti-ice-snow is arranged again, can prevent because winter circuit freeze and the generation of the accident that causes.The metal wire cross section of the outer concentric stranding of core is Z-shaped, compares for circular metal wire with common cross section, can improve the filling rate of conductive layer, thereby improve conductive capability.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the another kind of structural representation of the utility model.
Fig. 3 is the structural representation of core part.
Embodiment
As Fig. 1, compound double capacity conductor shown in Figure 3; the core 2 of its center for making by carbon fiber; be coated with layer protecting film 3 at core, twisting with one heart outside core and being shaped on three layer cross sections is Z-shaped metal wire 1, and metal wire is annealed aluminum wire or heat resistant aluminum alloy wire.Every layer of metal wire comprises six roots of sensation metal wire at least.
According to requirement difference to the lead ability to transmit electricity, the thickness of lead can change to some extent, can outside core, twist system three-layer metal line as shown in Figure 1 with one heart, also can be as shown in Figure 2, strand is made two layers of metal wire with one heart outside core, perhaps only outside core, twist system layer of metal line, the system of can certainly outside core, twisting with one heart four layers or more multi-layered metal wire with one heart.
When only strand is made the layer of metal line with one heart outside the core, the direction of lay of metal wire can be a clockwise direction, also can be counterclockwise, when the two-layer or two-layer above metal wire of the system of twisting outside the core, then the direction of lay of adjacent two layers metal wire is preferably inequality, and when being clockwise such as the direction of lay of ground floor metal wire, second layer metal cabling direction is preferably counterclockwise, and three-layer metal cabling direction is clockwise, and the like.
Core is to be made through steps such as impregnation, preheating, pultrusion, the moulding of heating under certain prestressing force control by carbon fiber, is that concentric stranding is carried out at the center with the core with aluminum steel or aluminium alloy wire then, promptly makes compound double capacity conductor.The outer diaphragm of core is to be formed by glass fibre and resin compounded, has avoided resembling the aluminum steel of plain conductor generation when energising and the couple corrosion problem between the steel core, can effectively delay the aging of lead, the useful life of improving lead.
In the utility model, the linear expansion coefficient of carbon fiber core is about 1/12 of common steel core, tensile strength Can reach 2399MPa, the proportion of core is about 1/4 of steel, can move under 200 ℃ of high temperature, with common Steel-cored aluminium strand is compared, have in light weight, intensity is big, high temperature resistant, the advantage such as degree of speeding is low, because the lead worker Therefore make temperature at 200 ℃, advantage cold-resistant, anti-ice-snow arranged again, can prevent because winter circuit freeze And the generation of the accident that causes. The metal wire cross section of the outer concentric stranding of core is Z-shaped, with common cross section is Circular metal wire is compared, and can improve the filling rate of conductive layer, thereby improves conductive capability.
