Abstract
A composite construction special-shaped tubular tubular bus, is formed by outer tubing string (1) and internal layer tubing string (2) suit, makes the centre bore of internal layer tubing string (2) form ground floor air duct (3); On the inner headed face of described internal layer tubing string (2), there is vertically evenly distributed elongated convex tendon I (4), on periphery, there is vertically evenly distributed elongated convex tendon II (5), and the inner headed face of the periphery of elongated convex tendon II (5) and outer tubing string (1) is combined with each other, make to form second layer air duct (6) between the inner headed face of outer tubing string (1) and the periphery of internal layer tubing string (2).The utility model adopts ectonexine composite construction, forms double-deck air passage, not only improved the rigidity of bus, and ventilation and heat performance is better, and ampacity is larger, and kelvin effect is lower, and power loss is less, and temperature rise is lower, and reliability is higher.
Description
Technical field:
The utility model belongs to tubular bus technical field, is specifically related to a kind of composite construction special-shaped tubular tubular bus.
Background technology:
Existing tubular bus is ganoid round copper pipe mostly, and along with carry the diameter of the increase tubular bus of electric current and voltage grade also to increase thereupon, not only increase manufacturing cost and project cost, and can sag bent when large span, cause the generation distortion of bus junction and loose contact and cause overheated overvoltage, cause the accident.So existing tubular bus is limited in 35KV electric pressure substantially with interior use.The applicant has applied for " all insulation shielding inside and outside circle special-shaped tubular tubular bus (CN203521027U) " utility model patent for this reason, has improved the rigidity of bus, guarantees that bus junction is substantially indeformable and contacts well.But this patent only has an air duct, ventilation and heat performance needs to be promoted.In addition copper valency continue to rise in recent years, makes to take the cost of the tubular bus that copper material is raw material to rise rapidly, and product competitiveness in the market has been subject to serious restriction.
Summary of the invention:
The technical problem that the utility model solves: design a kind of composite construction special-shaped tubular tubular bus, adopt ectonexine composite construction, not only improved the rigidity of bus, and ventilation and heat performance is better, ampacity is larger, and kelvin effect is lower, power loss is less, and temperature rise is lower, and reliability is higher.
Technical solution of the present utility model: a kind of composite construction special-shaped tubular tubular bus, described tubular bus is formed by outer tubing string and inner layer pipe column sleeve dress, makes the centre bore of internal layer tubing string form ground floor air duct; On the inner headed face of described internal layer tubing string, there is vertically evenly distributed elongated convex tendon I, on periphery, there is vertically evenly distributed elongated convex tendon II, and the periphery of elongated convex tendon II and the inner headed face of outer tubing string are combined with each other, make to form second layer air duct between the inner headed face of outer tubing string and the periphery of internal layer tubing string.
The quantity of the convex tendon II having on the convex tendon I having in described inner circle and cylindrical is at least respectively 3, and is all symmetric arrays on cross section.
Described outer tubing string is copper pipe post, and internal layer tubing string is aluminum or aluminum alloy tubing string, and internal layer tubing string and convex tendon I and convex tendon II are integral type structure.
The quantity of described convex tendon I and convex tendon II is preferably respectively 6, and convex tendon I and convex tendon II are and are staggered each other.
The quantity of described convex tendon I and convex tendon II is preferably respectively 6, and convex tendon I and convex tendon II are corresponding arrangement one by one each other.
The advantage that the utility model compared with prior art has and effect:
1, adopt ectonexine composite construction, form double-deck air passage, not only improved the rigidity of bus, and ventilation and heat performance is better, ampacity is larger, and kelvin effect is lower, and power loss is less, and temperature rise is lower, and reliability is higher.
2, adopt copper aluminum compound structure, reduce the consumption of copper material, and then reduce the cost of product, improve the competitiveness of product in market.
Accompanying drawing explanation:
Fig. 1 is the cross section structure schematic diagram of the utility model the first embodiment,
Fig. 2 is the cross section structure schematic diagram of the utility model the second embodiment.
Embodiment:
1 the first embodiment of the present utility model is described by reference to the accompanying drawings.
A composite construction special-shaped tubular tubular bus, is formed by outer tubing string 1 and internal layer tubing string 2 suits, makes the centre bore of internal layer tubing string 2 form ground floor air duct 3; In the inner circle of described internal layer tubing string 2, there is vertically evenly distributed elongated convex tendon I 4, on periphery, there is vertically evenly distributed elongated convex tendon II 5, and the inner headed face of the periphery of elongated convex tendon II 5 and outer tubing string 1 is combined with each other, make to form second layer air duct 6 between the inner headed face of outer tubing string 1 and the periphery of internal layer tubing string 2.
The quantity of the convex tendon II 5 having on the convex tendon I 4 having in described inner circle and cylindrical is respectively 6, and is all symmetric arrays on cross section, is and is staggered each other.Described outer tubing string 1 is copper pipe post, and internal layer tubing string 2 is aluminum or aluminum alloy tubing string, and internal layer tubing string 2 and convex tendon I 4 and convex tendon II 5 are integral type structure.
2 the second embodiment of the present utility model is described by reference to the accompanying drawings.Basic structure is identical with embodiment 1, and difference is that convex tendon I 4 and convex tendon II 5 are corresponding arrangement one by one each other.
The third embodiment of the present utility model.Basic structure is identical with embodiment 1, and difference is that outer tubing string 1, internal layer tubing string 2 are aluminum or aluminum alloy tubing string.
The 4th kind of embodiment of the present utility model.Basic structure is identical with embodiment 2, and difference is that outer tubing string 1, internal layer tubing string 2 are copper pipe post.
On the utility model internal layer tubing string inside and outside circle, there is vertically evenly distributed elongated convex tendon, make internal layer tubing string on cross section, form polygonized structure, not only improved the rigidity of tubular bus, its amount of deflection when large span is controlled in code requirement, guarantee that tubular bus junction is substantially indeformable and contact well, meeting the specification requirement of electric power system; In addition, owing to the utlity model has double-deck air passage, ventilation and heat performance is significantly enhanced, so ampacity is larger, and kelvin effect is lower, and power loss is less, and temperature rise is lower, and reliability is higher, has reduced rate of failure.
Above-described embodiment, is preferred embodiment of the present utility model, is not used for limiting the utility model practical range, therefore all equivalent variations of being done with content described in the utility model claim all should be included in the utility model claim scope.
