Abstract

The utility model relates to a bus duct housing which comprises two main housings. Each main housing is provided with a longitudinal side board. The upper end and the lower end of the longitudinal side board are respectively provided with a first crossbeam and a second crossbeam which extend transversely. The end of the first crossbeam is provided with a first mounting wall which longitudinally extends upwards. The end of the second crossbeam is provided with a second mounting wall which longitudinally extends downwards. Each main housing is provided with a groove with an opening through a longitudinal side wall, the first crossbeam and the second crossbeam. In each groove, a heat radiation board which is parallel with the longitudinal side wall is arranged between the first crossbeam and the second crossbeam. An accommodating chamber for accommodating a bus is formed between the heat radiation boards. Each heat radiation board is provided with a plurality of transversely extending heat radiation projections on a side end surface which is next to the longitudinal side wall. The longitudinal side wall is provided with a plurality of heat radiation holes. According to the bus duct housing, through arranging a heat insulation space and ventilation holes on the longitudinal side wall, not only is excellent heat radiation effect ensured, but also the safety is improved.

Description

Bus groove case

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, moreover, because side plate directly is exposed in air, with respect to personnel, easily touch, therefore have certain potential safety hazard, while bus groove case ratio is easier to affected by environment, such as dust, air humidity etc. are larger on the radiating effect impact of bus groove case.

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, safe and reliable 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 plate, the two ends up and down of described longitudinal side plate have respectively first crossbeam and the second cross beam of horizontal expansion, the end of described first crossbeam has vertically upwardly extending the first assembly wall, the end of described second cross beam has vertical the second assembly wall to downward-extension, described main casing forms the groove with opening by longitudinal side wall and first crossbeam and second cross beam, in described groove, be provided with the heating panel parallel with longitudinal side wall between described first crossbeam and second cross beam, the opening that described main casing the has setting that corresponds to each other and connect, and then be formed for the cavity that holds of accommodating bus bar between described heating panel, and form insulated space between described heating panel and described longitudinal side wall, on described heating panel, near the heat radiation projection that is provided with several horizontal expansions on the side end face of longitudinal side wall, offer several ventilation holes on described longitudinal side wall.

Concrete, described main casing forms fastening installation by bolt in the position that connects of the first assembly wall and the second assembly wall respectively.

the utility model is by the above-mentioned improvement to prior art, reached the beneficial effect of following three aspects:: 1, owing to being provided with insulated space and offering ventilation hole in main casing on longitudinal side wall, after making the heat of bus bar reach heating panel, carry out heat exchange with the air in insulated space, carry out effective circulation of air by extraneous air by the air in ventilation hole and insulated space again, thereby when reaching effective radiating effect, make the temperature comparison of longitudinal side wall be unlikely to make the injury to personnel that touches bus groove case close to room temperature, embody safe and reliable characteristic, 2, 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, 3, because only having two main casing docking with heating panel, 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.
