By structure and working condition, bus duct can be divided into several large classes such as air-insulated type bus duct, concentration bus duct and fire resistant busbar.Wherein the main structure of concentration bus duct is by coated for bus insulating material formation insulating barrier, dense arrangement, is close to the side plate of cell body.The bimetallic composite conductor material of copper covers aluminium composite bus to be a kind of with aluminium be core body, external sheath copper, it is complex as a whole the high-quality electric conductivity of aluminium, the energy of low cost and the high chemical stability of copper, lower contact resistance as conductor material.Thus, copper cover aluminium composite bus be a kind of not only can saving copper resource, but also the conductor material of product cost can be reduced.
At present, concentration bus duct common on the market comes with some shortcomings: the connected mode between busbar side board and cover plate and cross-over block adopts the connected mode that punching bolt is fixing on side plate mostly, be divided into screw at side plate outside and screw two kinds, side plate inside, screw is in the low scope of application affecting bus duct of the shell protection grade of side plate outside, and affect the attractive in appearance of shell, screw is the easy modification of sheet material when the inner processing technology complexity of side plate and punching, reduce the intensity of shell, easy modification in assembling transport installation process, complex manufacturing technology, cost is high, these shortcomings are affecting the result of use of concentration bus duct in low-voltage distribution field.
Chinese utility model patent ZL201220249907.8 discloses a kind of concentration bus duct, comprises bus duct shell, busbar and cross-over block, and described bus duct shell is made up of cover plate and side plate.Bus slot cover board and side plate fasten clamping by end bending edges, replace the mode that original screw connects, thus overcome prior art coping screw the shell protection grade of side plate outside is low and affect the scope of application of bus duct and affect shell defect attractive in appearance.But, the mode that this structure still adopts screw to connect between side plate and cross-over block,, thus, do not overcome coping screw and cause processing technology complicated in side plate inside, sheet material easy modification during punching, reduce the intensity of shell, easy modification in assembling transport installation process, complex manufacturing technology, the many defects of high in cost of production, and these shortcomings are affecting the result of use of concentration bus duct in low-voltage distribution field.
Summary of the invention
The technical problems to be solved in the utility model overcomes above-mentioned the deficiencies in the prior art exactly, and provides a kind of rational in infrastructure, and intensity is high, Stability Analysis of Structures, thermal diffusivity are good, the simple intensive copper-aluminum compound bus duct of process and assemble.
For solving the problems of the technologies described above, the technical solution of the utility model is:
A kind of intensive copper-aluminum compound bus duct, comprise bus duct shell, busbar, cross-over block and fixed head, described bus duct shell comprises upper and lower cover plates and left side plate, described busbar is Copper-Aluminum compound bus, skin is copper, internal layer is aluminium, be connected with the groove fixing of coupling by protruding rib between described cover plate and side plate, two row's draw-in grooves by outside relative two row chuck and the cross-over blocks of side board edge two jiaos match between left side plate and cross-over block fix and are connected, be connected by the groove fixing of protruding rib and coupling between described side plate outside and corresponding fixed head.
Rib protruding between described cover plate and side plate is the poker running through side plate front/rear end, or is made up of the segmentation that multistage is spaced apart.
Rib protruding between described cover plate and side plate and the number of recesses of coupling have one or two.
Between described side plate outside and fixed head, protruding rib is the poker running through side plate front/rear end.
Between described side plate outside and fixed head, the number of recesses of protruding rib and coupling has 8-20.
Described busbar skin arranges insulating barrier.
Described cover plate and side plate adopt almag section bar to make.
The beneficial effect of technical solutions of the utility model is:
1, structurally, bus slot cover board and side plate described in the intensive copper-aluminum compound bus duct of the utility model, side plate and cross-over block, all connected by clamping structure between side plate and fixed head, instead of the mode that the screw being positioned at side plate inside and outside described in prior art connects completely, not only overcoming prior art coping screw the shell protection grade of side plate outside is low affects the scope of application of bus duct and affects shell defect attractive in appearance, also overcome coping screw causes processing technology complicated in side plate inside simultaneously, sheet material easy modification during punching, reduce the intensity of shell, easy modification in assembling transport installation process, complex manufacturing technology, the many defects of high in cost of production.Thus, the utility model bus duct intensity is high, Stability Analysis of Structures, and thermal diffusivity is good, and process and assemble is simple, applied range.
2, structurally, rib protruding between cover plate described in the utility model and side plate can be the poker running through side plate front/rear end, also can be made up of the segmentation that multistage is spaced apart, quantity has one or upper and lower two, version is versatile and flexible, and embodiment is many, easy to implement; Between described side plate outside and fixed head, protruding rib is the poker running through side plate front/rear end, and the quantity of this rib has 8-20, not only increase the intensity of monolithic case, and radiating effect is better; In addition, the utility model busbar adopts copper-aluminum composite conductor, and skin is copper, and internal layer is aluminium, and performance parameter is substantially close to copper conductor, lightweight, cost is low, and energy-saving effect is remarkable; Shell adopts almag section bar to make, and weight is lighter.
3, to sum up, the intensive copper-aluminum compound bus duct of the utility model is rational in infrastructure, and intensity is high, Stability Analysis of Structures, thermal diffusivity are good, process and assemble is simple, applied range, and lightweight, cost is low, energy-saving effect significantly, therefore, is very suitable for promotion and implementation.
