Embodiment
For the technical scheme of technical problem that the present invention is solved, employing and the technique effect that reaches clearer, below in conjunction with accompanying drawing, the technical scheme of the embodiment of the present invention is described in further detail, obviously, described embodiment is only the present invention's part embodiment, rather than whole embodiment.Embodiment based in the present invention, those skilled in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Please refer to Fig. 1 and Fig. 2, it is respectively overall structure figure and the STRUCTURE DECOMPOSITION figure of a kind of low pressure hollow of the present invention bus duct.Along with emerging in large numbers of modernization project facility and equipment, the fast increasing of power consumption of all trades and professions, the appearance in especially numerous skyscrapers and large-sized workshop workshop, traditional cable as transmission pressure can not meet the demands in large electric current conveying system, and the parallel connection of multiway cable is used to on-the-spot installation and connected and brought inconvenience.Plug type bus duct arises at the historic moment as a kind of novel distribution wire, compare with traditional cable, when carrying, large electric current fully demonstrates its superiority, simultaneously owing to having adopted new technology, new technology, the junction, bus duct both ends greatly reducing and contact resistance and the temperature rise of branching port splicing position, and in bus duct, used high-quality insulating material, thus improved the security reliability of bus duct, make whole system more perfect.Bus duct in the present embodiment, is the further improvement to existing bus duct, for but be not limited only to above-mentioned occasion.
As shown in the figure, bus duct in the present embodiment, comprise housing, enclosure interior is divided into a plurality of parallel insulated cavities, one strip conductor 1 is set in each insulated cavity, described conductor 1 is low pressure hollow conductor, and described housing comprises upper shell 31 and lower house 32, and described upper shell 31 is fixedly connected with lower house 32.The link of a corresponding lower house of described upper shell 31 is provided with outside clad structure, and another link is provided with evagination waterproof construction; Described lower house 32 has the link identical with upper shell 31, upper shell 31 and lower house 32 is by screw 33 or rivet fixedly time, the outside clad structure of upper shell 31 and the outside clad structure of lower house 32 encase respectively the evagination waterproof construction of lower house 32 and the evagination waterproof construction of upper shell 31 from outside, screw 33 or rivet are fixed through outside clad structure and evagination waterproof construction.Described in each, insulated cavity is surrounded by upper insulating part 21, lower insulating part 22 and two phase insulation parts 23, is provided with a phase insulation part 23 between two adjacent insulated cavities.One group of opposite side of the cross section of described conductor 1 is isometric line segment, and another group opposite side is for waiting semicircle of radius; Corresponding with the cross section of conductor 1, described upper insulating part 21 and lower insulating part 12 are provided with the groove that cross section is semicircle, and described phase insulation part 23 is planar structure.Described housing is for being almag housing.The width of described housing is 9～11 centimetres, and the thickness of described housing is 3～6 millimeters.Described conductor 1 is the conductor that surface adopts the processing of isolated insulation technology.Described conductor 1 is cathode copper conductor, aluminium conductor, aluminium alloy conductor or copper aluminum composite material conductor.。
Low pressure hollow conductor is set in this bus duct, then housing is divided into upper shell 31 is fixedly connected with lower house 32, hollow conductor has reached maximized radiating effect by chimney type wind tunnel effect, housing is divided into upper shell 31 and lower house 31, both connecting portions superpose naturally, form " Asia " character form structure, strengthened the mechanical strength of bus duct.Structurally, this bus duct inner hollow conductor adopts the insulation of novel overall packing technology close-packed arrays, and closed assembly becomes the cramped construction of integral heat sink mutually.Molded (aluminium alloy) closure not only has higher mechanical strength, and has excellent corrosion resistance and thermal diffusivity, can be used as 100% earthing conductor and uses.This structure can the every impedance of efficient balance, thereby greatly reduces the loss of voltage of bus duct system.Utilize hollow technology.Conductor adopts cathode copper, raffinal, the copper aluminum composite material of high-quality; Adopt new insulation material, class of insulation B level, long-term work is still can keep good state of insulation at 130 ℃ of environment.Bus-bars conductor surface adopts isolated insulation technical matters, and the industrial frequency withstand voltage that can bear 3750V lasts 1mim without puncturing and flashover phenomenon.Ultrathin, only 10 centimetres of bus duct body width, shell adopts double-U-shaped structure, in evagination waterproof construction, is not only to protrude one deck waterproof material, further the housing of waterproof material below has been carried out to thickening design, the coupling part of housing is not only thickness of shell twice, but the design thicker than thickness of shell twice further embodied the perfect adaptation of " mouth " font structure and " Asia " character form structure, load is good, can realize large span level and install.Compact " sandwich " structure, adopts almag section bar shell, more than thickness reaches 3mm, unique heat sink design, the cooling surface area of super large, the conductor 1 that makes to abut against together can distribute heat soon by shell, effectively reduce bus temperature rise.Bus duct in the present invention adopts self-piercing rivet technique, and volume is little, compact conformation, and bus duct total length is intensive, and profile is very attractive in appearance.In use, because aluminium alloy is weak magnetic material, therefore in use can not produce eddy current and magnetic loss.By evagination waterproof construction, realize totally-enclosed design, possessed four anti-functions anticorrosion, moistureproof, dustproof, waterproof.Degree of protection is up to IP66.Adopt the nonmagnetic substance aluminum alloy casing that electric conductivity is good to make protection ground wire, be enclosed in busbar surrounding, because it is as much as possible near three-phase bus bar, reach reactance minimum.And shell sectional area is up to 2.5 to 4 times of phase cross-sectional area, and the remittance row (bus duct) who meets International Electrotechnical Commission's announcement and promotion is completely usingd shell as earthing conductor.
Above content is only preferred embodiment of the present invention, for those of ordinary skill in the art, according to thought of the present invention, all will change in specific embodiments and applications, and this description should not be construed as limitation of the present invention.
