Abstract
The utility model discloses a kind of diameter enlarging bus bar used for intelligent electric network, comprise expanding supporting layer and the conductive layer being stranded in expanding supporting layer periphery; The aluminium-alloy pipe that described expanding supporting layer adopts the aluminum alloy strip of linkage structure to make.Diameter enlarging bus bar of the present utility model has that enlarging rate is large, flexible, good bending property, conduct electricity very well, intensity is large, fail safe good, current capacity is strong, without electromagnetic consumable with without advantages such as electrochemical corrosion, for in Ultra-high Voltage Substations, the diameter of wire can be considerably increased, reduce corona and radio interference level, improve diameter enlarging bus bar safety in utilization.
Description
Technical field
The utility model relates to a kind of diameter enlarging bus bar used for intelligent electric network.
Background technology
Along with the electric pressure of overhead transmission line is more and more higher, for the connection for voltage power distribution equipment at different levels in transformer station, and the connection of the electric equipment such as transformer and corresponding power distribution equipment, namely collect, distribute and transmit the bus of electric energy, its requirement is also more and more higher, special in the transformer station being positioned at High aititude geographical position, the electric field of its bus used, magnetic field, audible noise, and radio interference level can substantially exceed related request, this not only can bring environmental pollution, and a large amount of energy loss can be produced, the best technique means addressed these problems increase bus diameter.
At present, increase the method for bus external diameter main as: one, increase wire glass, but this will certainly increase the weight of bus, thus add the load of erection bus load tower; Two, employing is dredged around structure, namely some single lines are extracted out relatively to increase bus stranded layer at the twisted wire internal layer of common lay configuration, thus reach expanding object, but this enlarging rate taking out the expanding mode of stock is little, enlarging rate is generally below 1.2, therefore, it is only only applicable in high-tension transmission circuit, and can not meet the requirement of extreme high voltage high altitude localities to bus.For this reason, people begin one's study the larger wire of enlarging rate, and as adopted embossing aluminium pipe structure, but the bus of this structure is comparatively hard, not flexible, not easily replys after bending.
Utility model content
The purpose of this utility model solves prior art Problems existing, provides the diameter enlarging bus bar used for intelligent electric network that a kind of intensity is large, flexibility is good.
The technical scheme realizing the utility model object is a kind of diameter enlarging bus bar used for intelligent electric network, comprises expanding supporting layer and the conductive layer being stranded in expanding supporting layer periphery; The aluminium-alloy pipe that described expanding supporting layer adopts the aluminum alloy strip of linkage structure to make.
The external diameter of described expanding supporting layer is selected according to wire enlarging rate, and supporting layer external diameter is at 10mm ~ 100mm.
The tight uniform winding of described conductive layer is arranged in expanding supporting layer periphery.
Described conductive layer at least arranges one deck; Every layer forms by single line is stranded.
Described every layer of single line can be circle line, also can be trapezoidal, " S ", the various special-shaped wire such as " Z " shape; Also can be internal layer be, and circle line skin is various special-shaped molded line;
Have employed technique scheme, the utility model has following beneficial effect: (1) the utility model adopts linkage structure as expanding supporting layer, very soft, improves the flexibility of wire, reduces bending radius, constructability; Comprehensively solve and adopt at present embossing aluminium pipe structure comparatively hard, not flexible, the not easily problem such as reply after bending.
(2) expanding supporting layer of the present utility model adopts aluminum alloy strip, and aluminum alloy strip has intensity greatly on the one hand, has good tension and crushing resistance, therefore can improve wire-break power, and can reduce pipe thickness, support effect is good simultaneously; On the other hand, conduct electricity very well, both played expanding effect, again can loaded current, improve current carrying capacity of conductor; Again, aluminum alloy strip is nonmagnetic, can not produce magnetic hysteresis loss, reduces line loss, improves bus service life.
(3) to adopt the aluminum alloy strip of linkage structure to make aluminium-alloy pipe easy to process for the utility model, can according to the requirement of different size diameter enlarging bus bar, and be processed into the pipe of various outer diameter, accuracy is high, and cost is lower; Its flight pitch adjustable range is large in addition, and therefore, it is convenient to coordinate with gold utensil;
Accompanying drawing explanation
In order to make content of the present utility model more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail, wherein
Fig. 1 is structural representation of the present utility model.
Fig. 2 is another kind of structural representation of the present utility model.
Attached number in the figure is: expanding supporting layer 1, conductive layer 2.
Embodiment
(embodiment 1)
See Fig. 1, the one diameter enlarging bus bar used for intelligent electric network of the present embodiment, comprise expanding supporting layer 1 and the conductive layer 2 being stranded in expanding supporting layer 1 periphery; The aluminium-alloy pipe that described expanding supporting layer 1 adopts the aluminum alloy strip of linkage structure to make.Described conductive layer 2 closely uniform winding is arranged in expanding supporting layer 1 periphery.Described conductive layer 2 arranges 1 layer; Every layer forms by single line is stranded, and inner-layer conducting layer adopts circle line, outer conducting layer adopts Z-shaped.The material of conductive layer 2 can be aluminum steel, high strength alumin ium alloy line, middle strength aluminum alloy line, heat resistant aluminum alloy wire, high strength heat resistant alloy line.The cross sectional shape of the single line of conductive layer 2 is trapezoidal, can certainly be other shapes such as circle line, Z-shaped or S shape.The shape of conductive layer 2 between which floor can be the same or different.
As shown in Figure 2, conductive layer 2 is two-layer, adopts one deck circular single line 2-1 stranded, and one deck Z-type single line 2-2 is stranded forms.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
