Abstract
The utility model relates to a hollow expanded diameter conductor belonging to the electric power transport technology field. The provided twisted aluminum tube set supporting hollow expanded diameter conductor is characterized in that the center of the conductor is a set of twisted aluminum tubes (1), at least two and at most four single wire twisting layers (2) are arranged and wound on the outsides of the set of twisted aluminum tubes mutually, densely and reversely, and the single wire twisting layers (2) are aluminum single wire twisting layers, high strength aluminum alloy single wire twisting layers or aluminum single wire and high strength aluminum alloy single wire mixed twisting layers. Compared with the conventional hollow expanded diameter conductor, the comprehensive property of the twisted aluminum tube set supporting hollow expanded diameter conductor is improved substantially. The twisted aluminum tube set supporting hollow expanded diameter conductor is stable in structure, strong in corrosion resistance and long in service life, enables the complexity of the manufacture and construction processes to be reduced and the efficiency to be improved, enables the overall weight of the conductor to be reduced while improving the tensile strength and carrying capacity slightly, is better in tension-weight ratio, abandons a T-shaped crimping head, and is more reliable in crimping quality by using the conventional aluminum stranded conductor crimping tubes.
Description
Technical field
The utility model relates to a kind of high voltage, the transmission of electricity of high altitude localities circuit and low corona and the hollow expanded diameter conductor to radio and the low interference of HF communication for substation bus bar, relate in particular to a kind of stranded aluminum pipe group and support hollow expanded diameter conductor, belong to electric power transportation technology field.
Background technology
Hollow expanded diameter conductor is transmission of electricity equipment conventional in high voltage power transmission and transforming circuit, multiplexly in high altitude localities and 330KV and 500KV transformer station, as bus, uses.Traditional hollow expanded diameter conductor is the support component as hole enlargement with galvanized metal flexible hose, and object is that twisted wire external diameter is expanded, and reduces the electric field strength on twisted wire surface, avoids producing visual corona, reduces wireless interference.The enlarged diameter effect of hollow expanded diameter conductor is fine, but owing to using galvanized metal flexible hose as support component, the shortcoming of its corrosion-resistant has had a strong impact on the useful life of wire.While is as mixed the strand between internal layer aluminum steel of steel wire of reinforced element, because the elasticity difference of steel, aluminium is large, and the excessive softness of galvanized flexible tube, cause the structural stability of expanded conductor poor, manufacture and construction process requirement high, production and efficiency of construction is not high and the quality of connection of T junction during conductor compression jointing is poor.In order to make up above deficiency, be necessary expanded conductor to carry out new design.
Summary of the invention
The utility model, in order to make up the above-mentioned weak point of prior art, has carried out new design to expanded conductor, provides a kind of stranded aluminum pipe group to support hollow expanded diameter conductor.
Complete foregoing invention task, the utility model adopts following technical proposals:
Stranded aluminum pipe group supports a hollow expanded diameter conductor, and the center of described wire is one group of stranded aluminum pipe group, and in the outside of stranded aluminum pipe group, mutually reverse solid matter is being wound around at least two-layer, maximum four layers of single line stranded layer; Described single line stranded layer is aluminium single line stranded layer, high-strength aluminum alloy single line stranded layer or aluminium single line and high-strength aluminum alloy single line mixing stranded layer.
Described stranded aluminum pipe group is by seven stranded forming of aluminum pipe.
Described stranded aluminum pipe group can meet the requirement of wire to bending property completely, compare the galvanized metal flexible hose that traditional hollow expanded diameter conductor uses simultaneously larger radial support power can be provided, can provide the not available axial tension of galvanized metal flexible hose and conductive capability simultaneously, structure will be stablized a lot, and corrosion resistance is stronger, can effectively improve the whole service life of wire;
Described aluminium single line stranded layer, high-strength aluminum alloy single line stranded layer have higher tensile strength and good electric conductivity, thereby can improve the whole tensile strength of wire for wire provides axial resistance to tension in conduction, than the steel wire supporting material weight of traditional expanded conductor is lighter, electric conductivity is superior, is a kind of good conduction supporting material;
The utlity model has following advantage: by appropriate design, the combination of stranded aluminum pipe group, aluminium single line stranded layer, high-strength aluminum alloy single line stranded layer, making the combination property of built on stilts expanded conductor compare traditional hollow expanded diameter conductor has had and has significantly improved: Stability Analysis of Structures, corrosion resistance is strong, wire extends useful life, manufacture and the reduction of complicated construction technique degree, efficiency improves, when tensile strength and ampacity slightly improve, wire overall weight reduces, draw anharmonic ratio more excellent, coupling compression joint better quality.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure, 1, stranded aluminum pipe group, 2, single line stranded layer.
Embodiment
With the embodiment providing, the utility model is illustrated by reference to the accompanying drawings:
As shown in Figure 1, a kind of stranded aluminum pipe group supports hollow expanded diameter conductor, and the center of described wire is one group of stranded aluminum pipe group 1, and in the outside of stranded aluminum pipe group 1, mutually reverse solid matter is being wound around at least two-layer, maximum four layers of single line stranded layer 2; The principle of each layer of single line stranded layer direction of lay is that the outermost layer of wire integral body is dextrad, and inside adjacent layer is opposite direction successively.In this embodiment, described stranded aluminum pipe group 1 is by seven regular stranded forming of aluminum pipe; Described single line stranded layer 2 is two-layer; Described single line stranded layer 2 is aluminium single line stranded layer, high-strength aluminum alloy single line stranded layer or aluminium single line and high-strength aluminum alloy single line mixing stranded layer.As, internal layer is aluminium single line stranded layer, skin is high-strength aluminum alloy single line stranded layer; Or internal layer is high-strength aluminum alloy single line stranded layer, skin is aluminium single line stranded layer; Or internal layer, skin are the stranded layer that aluminium single line mixes with high-strength aluminum alloy single line; Or one deck is aluminium single line stranded layer or high-strength aluminum alloy single line stranded layer, another layer is the stranded layer that aluminium single line mixes with high-strength aluminum alloy single line; Can, according to the whole burst of intensity of wire and the different requirements of D.C. resistance, select and combine.
