The utility model provides a kind of concentration bus duct, comprise cover plate, side plate and busbar, described cover plate comprises upper cover plate, the lower cover of integral type and the distance piece that connects upper cover plate and lower cover, biside plate forms two relatively independent chambers with described upper cover plate, lower cover and distance piece respectively, and described busbar places described two chambers respectively.
Alternatively, cavity is arranged at interval between described two relatively independent chambers.
Alternatively, be distributed with fin on described upper cover plate, lower cover and the biside plate.
Alternatively, the upper end of described busbar and bottom are sealed with insulation strip.
Alternatively, described cover plate and side plate are almag.
Alternatively, described busbar is copper bar or aluminium row.
Alternatively, described biside plate rides over by air clamper with described busbar.
Alternatively, described biside plate and described upper cover plate and lower cover link together by thread tapping.
Alternatively, the exit of described bus duct is connected with the joint connecting plate.
Bus duct of the present utility model is compact conformation, mechanical strength height not only, and radiating effect is very good, improves about 1 times than traditional bus duct radiating effect, therefore can make improve about 30% the useful life of busbar.
Description of drawings
By reading hereinafter detailed description of the preferred embodiment, various other advantage and benefits will become cheer and bright for those of ordinary skills.Accompanying drawing only is used for the purpose of preferred implementation is shown, and does not think restriction of the present utility model.And in whole accompanying drawing, represent identical parts with identical reference symbol.In the accompanying drawings:
Fig. 1 concentration bus duct of the present utility model cross section structural representation.
Embodiment
The utility model will be further described below in conjunction with accompanying drawing and concrete execution mode.
The utility model provides a kind of concentration bus duct, comprise cover plate, side plate and busbar, described cover plate comprises upper cover plate, the lower cover of integral type and the distance piece that connects upper cover plate and lower cover, biside plate forms two relatively independent chambers with described upper cover plate, lower cover and distance piece respectively, and described busbar places described two chambers respectively.
Fig. 1 shows concentration bus duct of the present utility model cross section structural representation.As shown in fig. 1, described concentration bus duct comprises upper cover plate 1, the lower cover 2 of integral type, connects distance piece 3, side plate 4 and the busbar 5 of upper cover plate and lower cover.Described biside plate 4 forms two relatively independent chambers with described upper cover plate 1, lower cover 2 and distance piece 3 respectively.When transmission line is four-wire system, respectively insert two busbars respectively in described two separate chamber; When transmission line is five-wire system, insert two busbars in the chamber, insert three busbars in another chamber.
Compared to prior art all busbars are placed a chamber, bus duct described in the utility model places two separate chamber respectively with described busbar, make busbar separately to dispel the heat, not only avoided busbar to concentrate in together the not vaporific drawback of heat, also increase area of dissipation, made the heat dissipation of busbar body be greatly improved.And, because cover plate is integrated, make higher than existing bus duct of the mechanical strength of bus duct described in the utility model, so the intensity that can bear is bigger, more durable.
In order further to improve radiating efficiency, cavity is arranged at interval between described two relatively independent chambers.As shown in fig. 1, be equipped with inside also cavity 6 at interval between two separate chamber of busbar.This cavity 6 can be used as the passage of thermal wind exhausting, and being positioned at the heat that the busbar of these cavity both sides distributes can discharge bus duct through this passage, by this passage, can also increase convection current and the flowability of air, accelerates the discharge of heat, promotes radiating efficiency.
Described distance piece can be tabular, strip or other Any shape, as long as itself and upper cover plate, lower cover and two side plates can form two independent cavity.Described distance piece can be interblock dividing plate or a spacer bar, and at this moment, described two independent cavity lay respectively at the both sides of distance piece.Preferably, described distance piece is two interblock dividing plate or spacer bars, and keeps at a certain distance away between two interblock dividing plates or the spacer bar, to form cavity 6 as shown in fig. 1, makes that described two independent cavity are spaced apart by this cavity 6, forms the passage of thermal wind exhausting.
Be distributed with fin on the upper cover plate of described bus duct, lower cover and the biside plate.As shown in fig. 1, the outside of the outside of biside plate 4 and upper cover plate 1 and lower cover 2 is distributed with fin 7.After the heat that busbar distributes reaches upper cover plate and lower cover, can distribute quickly via these fin, thereby further improve the radiating efficiency of busbar.
During the assembling bus duct, busbar and distance piece are close to, by air clamper side plate are ridden on the busbar tightly then, then with electric tool and thread tapping side plate and upper cover plate, lower cover are locked.The upper end of described busbar contacts with upper cover plate, and the lower end contacts with lower cover, causes damage for fear of the upper and lower side of busbar in installation process owing to stressed, can form certain protection to it in the top and bottom of busbar sealing label insulation strip 8.It will be understood by those skilled in the art that, tight connected mode between busbar described in the utility model and side plate and side plate and the cover plate is not limited to the mode described in the present embodiment, and any mode that busbar and side plate and side plate and cover plate can be tightened together all can adopt.
Cover plate and the side plate of bus duct described in the utility model are made by almag.Because almag aluminium has advantages such as the hard amount of matter is light, density is low, thermal diffusivity is better, crushing resistance is stronger, corrosion-resistant, cover plate and side plate adopt the almag section bar, both be conducive to the heat radiation of bus duct, strengthened shell rigidity again, also be convenient to install, alleviated bus duct weight simultaneously, but large span design and minimizing mounting bracket.Certainly, described cover plate and side plate also can be made by other materials, as long as satisfy the production standard of bus duct shell.
Busbar described in the utility model is copper bar or aluminium row.Be understandable that the busbar of other kinds also is applicable to the utility model.
The exit of described bus duct is connected with joint connecting plate 9, as shown in fig. 1.Described joint connecting plate can be protected the busbar that stretches out bus duct.
Two chambers dispel the heat concentration bus duct described in the utility model by concentrating the busbar that wraps up to place mutually independently respectively originally, have improved radiating efficiency greatly.Because the busbar radiating effect is good, excellent protection is provided therefore for the insulating material that is wrapped in the busbar surface, improve bus useful life thereby reach, economical with materials reduces the purpose of use cost.And cover plate of the present utility model is formed in one, and mechanical strength is improved, and the intensity that makes bus duct to stand also improves greatly, has prolonged its useful life.
It should be noted that above-described embodiment describes the utility model rather than the utility model is limited, and those skilled in the art can design alternative embodiment under the situation of the scope that does not break away from claims.In the claims, any reference symbol between bracket should be configured to limitations on claims.Word " comprises " not to be got rid of existence and is not listed in element or step in the claim.Being positioned at word " " before the element or " one " does not get rid of and has a plurality of such elements.Any order is not represented in the use of word first, second and C grade.Can be title with these word explanations.
