Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in the figure, in order to solve the problems of the technologies described above, a kind of bus duct of the present invention, comprise housing 1, a plurality of current－carrying conductor 2, described current－carrying conductor 2 is longitudinally arranged in described housing 1, and described current－carrying conductor 2 is cylinder, and described current－carrying conductor 2 peripheries are provided with corresponding insulating barrier 3; Described housing 1 is comprised of the first plate body 11, the second plate body 12, and described the first plate body 11 links into an integrated entity by coupling assembling respectively at two ends Shang Xia 12 with described the second plate body; Described coupling assembling comprises and the connecting plate 111 that is arranged on described the first plate body 11 ends, be arranged on the installing hole 121 of described the second plate body 12 ends, during connection, described connecting plate 111 inserts in described installing hole 121, and with installing hole 121 interference fit, make the first plate body 11 be fixedly connected with and be integral with the second plate body 12, be combined into housing 1; The first plate body 11 is plate, and two ends are equipped with outer flanging 5, described the first plate body 11 parallel longitudinals be provided with a plurality of semi-circular recesses 4; The second plate body 12 is plate, two ends are equipped with outer flanging 5, described the second plate body 12 parallel longitudinals be provided with a plurality of semi-circular recesses 4, during installation, semi-circular recesses 4 on the first plate body 11 matches with the semi-circular recesses 4 on described the second plate body 12, forms circular cavity and in current－carrying conductor 2 is installed.Because described current－carrying conductor 2 is longitudinally arranged in described housing 1, described current－carrying conductor 2 is cylinder, and described current－carrying conductor 2 peripheries are provided with corresponding insulating barrier 3; The heat producing during work can be by hollow the distributing of current－carrying conductor 2 inside, and because current－carrying conductor 2 is for hollow cylinder has increased area of dissipation, the heat that current－carrying conductor 2 is produced can conduct fast, thereby, greatly improved the heat dispersion of bus duct.In order further to improve the thermal diffusivity of this bus duct, can on the lateral surface of described the first plate body 11 and the second plate body 12, longitudinally be provided with respectively fin 4, the outer peripheral face of described fin 4 is provided with protruding stupefied 5,
In sum, the present invention has the following advantages:
