Abstract
The utility model relates to an adjustable bus duct which comprises an upper cover plate, a lower cover plate, side plates and adjustable bolts. The side plates include a vertical main plate and a first installation plate and a second installation plate which respectively extend at edges of the upper and lower ends of the vertical main plate along the transverse direction, the upper cover plate is overlapped onto the first installation plate, and the second installation plate is overlapped onto the lower cover plate; first positioning plates extending downwards in the vertical direction are arranged at edges of the left and right ends of the upper cover plate, and second positioning plates extending upwards in the vertical direction are arranged at edges of left and right ends of the lower cover plate; a transverse screwed hole is formed in each of the first and second positioning plates; and the adjustable bolts abut against the vertical main board of the side plates. According to the utility model, the side plates are adjusted in the transverse direction by screwing up or backing out the bolts in the screwed holes; and thus, according to the number and total width of bus bars, the side plates can be adjusted to be suitable for accommodating the bus bars, thereby effectively broadening application range of the bus duct.
Description
Technical field
The utility model relates to the bus duct mains system of low pressure power transmission and transformation line, belongs to the technical field that the power bus-bar groove is made, and is specifically related to a kind of adjustable bus duct.
Background technology
In order to meet the needs of the high-current low-voltage transmission line in industry, civil engineering construction, the bus duct mains system is all adopted in the power distribution design, continuing to increase along with the electric line capacity in recent years, the bus duct mains system is widely applied in engineering, the structural design of bus duct product is also from the air-insulated type to the dense insulation type, from the outer cover of steel plate to the aluminum alloy casing, realization progressively update; In prior art, bus duct comprises upper cover plate, lower cover and two side plates, and place bus bar in the accommodating cavity that forms between upper cover plate, lower cover and side plate, yet, because the space that accommodating cavity limits is more fixing, therefore, each bus duct can only be applicable to the bus bar of respective numbers, for in the situation that the bus bar quantity in electric power system is uncertain or needs are changed, the scope of application of described bus duct just seems and relatively limits to, often need to change bus duct, the corresponding expenditure cost that improved.
Summary of the invention
The purpose of this utility model is to overcome the defect of prior art, and a kind of adjustable bus duct simple in structure, applied widely is provided.
for achieving the above object, the utility model adopts a kind of adjustable bus duct, comprise upper cover plate, lower cover and two side plates and adjustable bolt, and at described upper cover plate, form accommodating cavity between lower cover and side plate, this accommodating cavity content is received several bus bars that coating dielectric film and be closely adjacent to each other, the up and down both sides of described bus bar in accommodating cavity are provided with insulation strip, described side plate has vertical mainboard and respectively from the first mounting panel and second mounting panel of the edge horizontal expansion of two ends up and down of this vertical mainboard, described upper cover plate is overlapped on described the first mounting panel, described the second mounting panel is overlapped on described lower cover, the edge, two ends, left and right of described upper cover plate has vertical the first location-plate to downward-extension, the edge, two ends, left and right of described lower cover has vertically upwardly extending the second location-plate, offer respectively the horizontal thread hole adaptive with the external screw thread of described adjustable bolt on described the first location-plate and the second location-plate, described expansion screw forms butt by vertical mainboard of described screwed hole and described side plate.
Concrete, the position that connects with described adjustable bolt on described vertical mainboard offers counterbore, and the external diameter of the internal diameter of this counterbore and the screw portion of described adjustable bolt is adaptive.
Concrete, laterally be extended with several heat sink strips on described vertical mainboard.
By the above-mentioned improvement to prior art, due to the precession of adopting adjustment screw on screwed hole or revolve the mode of moving back, realize the laterally adjustable of side plate, therefore, can be according to the quantity of bus bar and the compact arranged integral width of bus bar and side plate is laterally adjusted and adapted to the placement of described bus bar, effectively enlarged the scope of application of bus duct.
