Abstract
The utility model relates to an adjustable bus duct which comprises an upper cover plate, a lower cover plate, two side plates and adjustable bolts. An accommodation cavity is formed among the upper cover plate, the lower cover plate and the side plates, wherein multiple bus bars wrapped in insulation films are accommodated in the accommodation cavity, and the bus bars are closely adjacent to each other; the side plates include vertical main plates and installation plates, and each installation plate extends transversely from the two ends of the main board and is equipped with long transverse circular holes; and installation holes are respectively formed in the upper and lower cover plates in positions corresponding to the long transverse circular holes, and the adjustable bolts respectively successively penetrate through the installation holes and the long transverse circular holes to fasten the cover plates with the side plates. According to the utility model, the long transverse circular holes are formed in the installation plates of the side plates and are matched with the installation holes in the upper and lower cover plates, so that the side plates can be adjusted according to the transverse stroke of the long transverse circular holes; and then the adjustable bolts can be used for fastening and installation, so that the application range of the bus duct is wide.
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, improved expenditure cost.
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, wherein said side plate has vertical mainboard and from the mounting panel of the two ends horizontal expansion of this vertical mainboard, offer horizontal slotted hole on described mounting panel, position corresponding with horizontal slotted hole on described upper cover plate and lower cover offers installing hole, described adjustable bolt passes installing hole successively, laterally slotted hole forms being fastenedly connected of cover plate and side plate.
Concrete, laterally be extended with several heat sink strips on described vertical mainboard.
By the above-mentioned improvement to prior art, after the installing hole offering on the mounting panel of side plate on horizontal slotted hole and cooperation upper cover plate and lower cover, make side plate to regulate according to the infeed stroke of horizontal slotted hole, the width of namely according to bus bar, closely rehearsing is adjusted to the relevant position of horizontal slotted hole and installing hole, then, by the fastening installation of adjustable bolt, obviously reached the effect applied widely of this bus duct.
Description of drawings
Fig. 1 is the front view of the utility model embodiment.
Embodiment
as shown in Figure 1, specific embodiment of the utility model is a kind of adjustable bus duct, comprise upper cover plate 1, lower cover 2 and two side plates 3 and adjustable bolt 4, and at described upper cover plate 1, form accommodating cavity between lower cover 2 and side plate 3, in the present embodiment, this accommodating cavity content is received six bus bars that coating dielectric film and be closely adjacent to each other 5, the up and down both sides of described bus bar 5 in accommodating cavity are provided with insulation strip 6, wherein said side plate 3 has vertical mainboard 30 and from the mounting panel 31 of the two ends horizontal expansion of this vertical mainboard 30, offer horizontal slotted hole 310 on described mounting panel 31, position corresponding with horizontal slotted hole 310 on described upper cover plate 1 and lower cover 2 offers installing hole, described adjustable bolt 4 passes installing hole successively, laterally slotted hole 310 forms being fastenedly connected between upper cover plate 1 and lower cover 2 and side plate 3.
Obviously as can be known, in the present embodiment, laterally be extended with six heat sink strips 32 on vertical mainboard 30 of described each side plate 3 in Fig. 1.
Above demonstration and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.Claim and equivalent thereof that the claimed scope of the utility model is appended define.
