Abstract
The utility model discloses a composite carbon fiber-cored double capacity conductor, wherein the center thereof is a conductor core made of carbon fibers and a plurality of layers of circular metal wires are concentrically stranded outside the conductor core. In the composite carbon fiber-cored double capacity conductor, the linear expansion coefficient of the carbon fiber conductor core is 1/12 that of a common steel core, the tensile strength can reach 2399MPa, the specific gravity of the conductor core is 1/4 that of steel, and the conductor core can run under 200 DEG C; compared with the common steel-cored aluminum strand, the composite carbon fiber-cored double capacity conductor has the advantages of light weight, high strength, high temperature resistance, low sag degree and the like; and because the working temperature of the conductor is 200 DEG C, the composite carbon fiber-cored double capacity conductor has the advantages of freezing resistance as well as ice and snow resistance and can be used for preventing the occurrence of accidents triggered by wire icing in winter.
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 high voltage electricity transmission conductive wire 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 operating temperature that improves lead is the effective ways that improve ability to transmit electricity under the sectional area of wire situation not increasing.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 carbon fiber core and holds lead for compound times, 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 carbon fiber core holds lead for compound times, the core of its center for making by carbon fiber, and strand is shaped on one deck circular metal line at least with one heart outside core.
Between core and circular metal line, layer protecting film is arranged.
Described metal wire is pure aluminum wire or aluminium alloy wire.
Strand is shaped on the double layer of metal line with one heart outside core.
Strand is shaped on the three-layer metal line with one heart outside core.
Strand is shaped on the layer of metal line with one heart outside core.
Adopt the carbon fiber core of technique scheme to hold lead for compound times, 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 under 200 ℃ of high temperature, move, compare 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.

Fig. 2 is the another kind of structural representation of the utility model.
Fig. 3 is the structural representation of core part.
Embodiment
Hold lead for compound times as Fig. 1, carbon fiber core shown in Figure 3, the core 2 of its center for being made by carbon fiber is coated with layer protecting film 3 at core, and strand is shaped on three layers of circular metal line 1 with one heart outside core, and metal wire is pure aluminum wire or heat resistant aluminum alloy wire.
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.
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 carbon fiber core and holds lead for compound times.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, compares with common steel-cored aluminium strand, have in light weight, intensity is big, high temperature resistant, the advantage such as degree of speeding is low, because the lead operating 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.
