Technical field
What the utility model low arc drop soft aluminum conductor related to is the extraordinary lead that a kind of overhead transmission line is used, and is applicable to the transformation of new construction overhead transmission line and overhead transmission line.
Background technology
High speed development along with Chinese national economy, demand to electric power increases substantially, the transmission line of original oepration at full load has been to satisfy the demands, overhead power transmission conducting wire is that electric energy is held the necessary carrier of delivering to receiving end from generating, is also consuming a part of energy when transmitting electric energy.Original steel reinforced aluminium conductor is 70～80 ℃ in continuous serviceability temperature, and transmission line capability is restricted.
Summary of the invention
The purpose of this utility model provides a kind of low arc drop soft aluminum conductor at above present situation, and being mainly used in overhead transmission line increases transmission of electric energy.Adopting the low arc drop soft aluminum conductor to solve the overhead power transmission conducting wire temperature can not be too high and the problem of sag, thereby increases transmission of electric energy, reaches the purpose that increases the transmission line dilatation.
The low arc drop soft aluminum conductor takes following scheme to realize: the low arc drop soft aluminum conductor partly is made up of core and conductor two, in the core arranged outside of carrying conductor is arranged.Conductor adopts 130-O type full annealing aluminum steel, and its conductance is not less than the annealed aluminum wire of 63%IACSS, is used for carrying electric current.After the lead operation working temperature raising that is under the tension force effect, the very fast generation elongation of annealed aluminum wire thigh permanent deformation, its mechanical load is all transferred to core.The linear expansion coefficient of lead is the coefficient of expansion of carrying core.Therefore the low arc drop annealed aluminum wire lead can be under higher temperature operate as normal.The low arc drop soft aluminum conductor has that sag is low, intensity is big, high temperature resistant, corrosion-resistant, advantage such as line loss is low.The core of carrying removes and adopts LB
10Outside Extra High Strength aluminium-clad steel wire or the EST Extra High Strength galvanized steel wire, also adopt G3A Extra High Strength galvanized steel wire or carbon fibre composite.
LB
10Minimum tensile strength less than 3.5mm reaches 1770Mpa to the external diameter of Extra High Strength aluminium-clad steel wire greater than 1.25, and the minimum tensile strength less than 4.25mm reaches 1700Mpa to external diameter greater than 3.5mm.

Described conductor can be the lead of the single line combination of circular cross-section.
Described conductor can be the lead of the combination of monofilaments of profiled-cross-section.
Described conductor can be the lead that the conductor of the conductor of combination of monofilaments in round cross section and odd-shaped cross section combination of monofilaments constitutes.
The utility model characteristics:
The low arc drop soft aluminum conductor is suitable for new transformation of building overhead transmission line and overhead transmission line.The low arc drop soft aluminum conductor adopts circle line, the molded lines structure of strand with one heart.The conductor of low arc drop soft aluminum conductor is to adopt full annealing aluminium, its conductance is not less than the annealed aluminum wire of 63%IACS, make the low arc drop soft aluminum conductor in use, sag amount when 120 ℃ of left and right sides and the sag of the steel core aluminium of same size strand in the time of 70 ℃ are very approaching, and ampacity has been about 180% of a same size steel core aluminium strand.The low arc drop soft aluminum conductor has that sag is low, intensity is big, high temperature resistant, corrosion-resistant, advantage such as line loss is low.
Description of drawings
The utility model is described in further detail below with reference to accompanying drawing.
Fig. 1 is the sectional side elevation of low arc drop soft aluminum conductor embodiment 1.
Fig. 2 is the sectional side elevation of low arc drop soft aluminum conductor embodiment 2.
Fig. 3 is the sectional side elevation of low arc drop soft aluminum conductor embodiment 3.
Embodiment
With reference to accompanying drawing 1-3, the low arc drop soft aluminum conductor partly is made up of core and conductor two, in core 3 arranged outside of carrying conductor is arranged.The low arc drop soft aluminum conductor adopts circle line, the molded lines structure of strand with one heart.
Partly form by core and conductor two with reference to accompanying drawing 1 low arc drop soft aluminum conductor, conductor 2 and conductor 1 are arranged in core 3 arranged outside of carrying.Conductor 1, conductor 2 are the lead of the single line combination of circular cross-section.
With reference to accompanying drawing 2 is that the low arc drop soft aluminum conductor partly is made up of core and conductor two, and the lead periphery is smooth circle, in core 3 arranged outside of carrying conductor 4 and conductor 5 is arranged.Conductor 4 and conductor 5 are the lead of the combination of monofilaments of profiled-cross-section.
With reference to accompanying drawing 3 is that the low arc drop soft aluminum conductor partly is made up of core and conductor two, in core 3 arranged outside of carrying conductor 6 and conductor 7 is arranged.Conductor is the lead that the conductor 7 of the conductor 6 of combination of monofilaments in round cross section and odd-shaped cross section combination of monofilaments constitutes.
The low arc drop soft aluminum conductor is combined with the core 3 of carrying by conductor 1, conductor 2.Conductor 1, conductor 2 are full annealing aluminium, and its conductance is lower than the annealed aluminum wire of 63%IACSS, approximately exceeds 2%IACS than common hard-drawn aluminium wire.In addition because the mechanical strength of annealed aluminum wire is lower, so during low arc drop soft aluminum conductor of the present invention work, the mechanical load of lead is mainly born by core.And annealed aluminum wire to have higher elongation be 20%～30%, elongation (1.2%～2.0%) than common hard-drawn aluminium wire is much higher, therefore when working temperature is higher than the migration point of steel reinforced aluminium conductor, the mechanical load of lead will all be transferred to core, be born whole tension force of lead by core.Because core has softening properties preferably, the intensity height, linear expansion coefficient is low and can work under higher temperature and do not reduce its mechanical strength.
