Abstract
The utility model relates t a bus duct housing which comprises two main housings. Each main housing is provided with a longitudinal side wall and transverse side walls which extend transversely from two ends of the longitudinal side wall. Then end of each transverse side wall is provided with a longitudinally extending mounting wall. The two main housings forms an accommodating chamber for accommodating a busbar through jointing setting of the mounting wall. The external surfaces of the longitudinal side wall and the transverse side wall are provided with a plurality of heat radiation projections. According to the bus duct housing, through improving the housing structure of the bus duct from a form which is composed of an upper cover board, a lower cover board, a left side board and a right side board to a structure a structure with two jointed main housings, a defect of non-ideal heat radiation effect of the bus duct because of mounting clearances among the upper cover board, the lower cover board and the side boards. Therefore, the bus duct housing provided by the utility model has obviously no mounting clearance because the bus duct housing is obtained through jointing the two main housings. The bus duct housing further has the following advantages: simple structure, low cost, large heat radiation area, and high heat radiation effect.
Description
Technical field
The utility model relates to a kind of bus duct that is applied to the low pressure power transmission and transformation line, relates in particular to a kind of bus groove case.
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 at upper cover plate, place bus bar in the accommodating cavity that forms between lower cover and side plate, yet, due to upper cover plate, there is gap unavoidably in assembling between lower cover and side plate, therefore, the extremely responsive and important bus duct for radiating effect, most heat distributes by side plate, and due to the reason of the assemblage gap that exists between cover plate and side plate, make the cooling effect of upper cover plate and lower cover always very poor, further make heat concentrate on side plate, cause side plate often not reach rapidly effectively radiating effect, and then affect useful life of bus duct.
Summary of the invention
The purpose of this utility model is to overcome the defect of prior art, provides a kind of simple in structure, with low cost and can effectively improve the bus groove case of radiating effect.
For achieving the above object, the utility model adopts a kind of bus groove case, comprise two main casings, described main casing has longitudinal side wall and from the lateral sidewalls of described longitudinal side wall two ends horizontal expansion, the end of described lateral sidewalls has the assembly wall of longitudinal extension, described two main casings arrange by connecting of assembly wall the cavity that holds that is formed for accommodating bus bar, are provided with several heat radiation projections on the outer surface of described longitudinal side wall and lateral sidewalls.
Concrete, install by bolted between the described assembly wall that connects.
The utility model is by the above-mentioned improvement to prior art, reached the beneficial effect of following two aspects: 1, because the shell structure with prior art median generatrix groove is improved to two main shell structures that connect by the form that upper cover plate, lower cover and two of left and right side plate form, and then avoided greatly affecting the dissatisfactory defect of bus duct radiating effect because of the existence of the fit-up gap of upper cover plate and lower cover and side plate, therefore, the apparent area of dissipation that increases main casing, improved radiating effect; 2, because only having two main casing docking, bus groove case of the present utility model forms, except not having the fit-up gap between cover plate and side plate, also obviously cancellation the use of upper cover plate and lower cover, and reduced the cost payout of upper cover plate and lower cover, not only simple in structure, and effectively reduce production cost.
Description of drawings
Fig. 1 is the schematic diagram of prior art median generatrix slot shell.
Fig. 2 is the front view of the utility model embodiment.
Embodiment
bus groove case structure in the prior art as shown in Figure 1, comprise that two the side plate c in upper cover plate a, lower cover b and left and right are assembled, those skilled in the art obviously as can be known, there is this assemblage gap d between upper cover plate a and lower cover b and side plate c, the existence of this assemblage gap d will affect the radiating effect of bus duct greatly, the most of heat that namely makes bus duct produce concentrates on side plate c, and the thermolysis of upper cover plate a and lower cover b is extremely small, and what show in Fig. 2 is specific embodiment of the utility model, it is bus groove case of the present utility model, comprise two main casings, described main casing has longitudinal side wall 10 and from the lateral sidewalls 11 of described longitudinal side wall 10 two ends horizontal expansions, the end of described lateral sidewalls 11 has the assembly wall 12 of longitudinal extension, in the present embodiment, obviously as can be known, described two main casings by connecting of assembly wall 12 arrange be formed for accommodating bus bar hold cavity 2, and pass through the fastening installation of bolt 3 between the described assembly wall that connects 12, be provided with a plurality of heat radiation projections 13 on the outer surface of described longitudinal side wall 10 and lateral sidewalls 11.
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.
Claims (2)
1. bus groove case, it is characterized in that: comprise two main casings, described main casing has longitudinal side wall and from the lateral sidewalls of described longitudinal side wall two ends horizontal expansion, the end of described lateral sidewalls has the assembly wall of longitudinal extension, described two main casings arrange by connecting of assembly wall the cavity that holds that is formed for accommodating bus bar, are provided with several heat radiation projections on the outer surface of described longitudinal side wall and lateral sidewalls.
2. a kind of bus groove case according to claim 1, is characterized in that: install by bolted between the described assembly wall that connects.
