Abstract
An aluminum tube supporting heat-resistant aluminum alloy expanding bus adopts a grained aluminum tube as a support, and a heat-resistant aluminum alloy single wire is stranded outside the grained aluminum tube. The aluminum tube supporting heat-resistant aluminum alloy expanding bus adopting the grained aluminum tube as the support expands the outer diameter of the bus, and simultaneously enhances radial pressure resistance and longitudinal flexibility.
Description
[technical field]
The utility model relates to diameter enlarging bus bar, relates in particular to the aluminum pipe supporting type heat resisting aluminium alloy diameter enlarging bus bar that a kind of transformer station, current conversion station use.
[background technology]
More employing aluminium stranded conductor is made bus in China order transformer station,, complex structure various in style, construction maintenance difficult because of aluminium stranded conductor, and external diameter can not satisfy the electric power requirement greatly inadequately, presents the trend that is eliminated gradually.In present project of transmitting and converting electricity, more commonly adopt diameter enlarging bus bar to solve the problems referred to above of aluminium stranded conductor.
At present, China transformer station, current conversion station use galvanized flexible tube as supporter with the heat-resisting aluminium alloy diameter enlarging bus bar usually.Yet, this diameter enlarging bus bar part that comes with some shortcomings.For example, the resistance to pressure and the corrosion resistance of galvanized flexible tube are not enough, make the total quality deficiency of diameter enlarging bus bar.
[utility model content]
In view of this, be necessary to provide the aluminum pipe supporting type heat resisting aluminium alloy diameter enlarging bus bar of a kind of resistance to pressure, good corrosion resistance.
A kind of aluminum pipe supporting type heat resisting aluminium alloy diameter enlarging bus bar, described diameter enlarging bus bar adopt the embossing aluminum pipe as supporter, and the outer strand of described embossing aluminum pipe is wound with the heat-resisting aluminium alloy single line.
Preferably, the embossing degree of depth of described embossing aluminum pipe is 4.0 ± 0.5mm, and the pitch of adjacent embossing is 20～22mm.
Preferably, described heat-resisting aluminium alloy single line is that conductance is the aluminium alloy wire of 60%IACS.
Preferably, the outer strand of described embossing aluminum pipe is wound with two layers of described heat-resisting aluminium alloy single line.
Preferably, the external diameter of described bundle line aluminum pipe is 52.5+0.5mm.
Preferably, the diameter of described heat-resisting aluminium alloy single line is 4.38mm.
Aluminum pipe supporting type heat resisting aluminium alloy diameter enlarging bus bar of the present utility model adopts pricks the line aluminum pipe as supporter, in the external diameter that has enlarged bus, has also strengthened radially resistance to pressure and vertically flexibility.
[description of drawings]
Fig. 1 is the schematic cross-section of preferred embodiment aluminum pipe supporting type heat resisting aluminium alloy diameter enlarging bus bar of the present utility model.
[embodiment]
For understanding the utility model better, the embodiment to utility model is described in detail below with reference to accompanying drawing.
As shown in fig. 1, the schematic cross-section of preferred embodiment aluminum pipe supporting type heat resisting aluminium alloy diameter enlarging bus bar of the present utility model.This aluminum pipe supporting type heat resisting aluminium alloy diameter enlarging bus bar adopts embossing aluminum pipe a as support, with radially resistance to pressure and the vertical flexibility that strengthens diameter enlarging bus bar.Outside embossing aluminum pipe a, strand is wound with 84 heat-resisting aluminium alloy single line b.
In the illustrated embodiment, pricking the outer strand of line aluminum pipe a has two-layer heat-resisting aluminium alloy single line b, and wherein, internal layer is 39 heat-resisting aluminium alloy single line b, and skin is 45 heat-resisting aluminium alloy single line b.In other optional embodiment, the number of plies of heat-resisting aluminium alloy single line b can be set according to different actual demands with every layer radical.
The external diameter of pricking line aluminum pipe a is 52.5+0.5mm.The embossing degree of depth (not shown) of embossing aluminum pipe a is 4.0 ± 0.5mm, and the pitch between adjacent embossing is 20～22mm.
It is that 4.38mm, conductance are the aluminium alloy wire of 60%IACS that heat-resisting aluminium alloy single line b adopts diameter, can improve the amount of damming of diameter enlarging bus bar.With the conductance be the aluminum-alloy wire of 60%IACS to replace traditional conductance be the aluminum-alloy wire of 58%IACS, can reduce resistance, improve conductance, improved ampacity and electric conductivity, strengthened heat resistance, reduced line loss, also increased benefit.
The nominal cross of aluminum pipe supporting type heat resisting aluminium alloy diameter enlarging bus bar is 1600mm
2, external diameter is 70.02mm, can reduce the electric field strength of bus, thereby can reduce corona loss, noise and radio interference.
Hot aluminium alloy diameter enlarging bus bar adopts embossing aluminum pipe a to do support in the above-mentioned aluminum pipe supporting type, has enlarged external diameter, has strengthened radially resistance to pressure and vertically flexibility.Heat-resisting aluminium alloy single line b conductance is that 60%IACS replacement conductance is a 58%IACS aluminium alloy single line, reduces resistance, improves conductance, has improved ampacity and electric conductivity, has strengthened heat resistance, has reduced line loss, has increased benefit.
This product can be used for transformer station, current conversion station correlation engineering such as 500kV, 750kV, 800kV, 1000kV, and this is the diameter enlarging bus bar of external diameter maximum so far.In project of transmitting and converting electricity, use above-mentioned aluminum pipe and support the imbody that the heat-resisting aluminium alloy diameter enlarging bus bar is promotion resources conservation, environmentally friendly power grid construction.Aluminum pipe supporting type heat resisting aluminium alloy diameter enlarging bus bar needn't increase metal material and energy self enlarged diameter extraly, reaches the minimizing corona loss, improves power delivery efficient, reduces electric energy loss, increases comprehensive benefit.
The above embodiment has only expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
