Abstract
The utility model discloses a single-pole multilayer composite bus bar, comprising insulating layers, a conductor bar and bonding layers, wherein the conductor bar is formed by bonding and compositing a plurality of thin metal plates with the same thickness through the bonding layers, and two surfaces of the conductor bar are respectively laminated with a layer of the insulating layers, and then made into a three-dimensional structure with a formed angle having the radian of R through hot press forming. The conductor bar is laminated by the plurality of thin metal plates, and enables current to be evenly distributed on each metal plate, thereby avoiding the problem that the surface of the bus bar is overheated due to the skin effect generated by high frequency; the integral thick metal plate is replaced by the multi-layer thin metal plates, thereby decreasing the rigidness of the bus bar and facilitating the installation and connection; and after being formed into the three-dimensional structure, the bus bar has high production efficiency, and is suitable for mass production.
Description
Technical field
The utility model relates to a kind of composite bus bar, particularly a kind of one pole multilayer composite bus row.
Background technology
Along with the fast development of power electronics cause, the composite bus bar application is more and more wider, and instructions for use is also more and more higher, and especially frequency is in the high frequency use occasion of several KHZ to hundreds of KHZ, and traditional busbar can't satisfy instructions for use.The conventional composite busbar structure is to select the suitable thickness copper coin as electric conducting material according to the operating current size, reaches the current density of designing requirement, thereby the temperature rise of control composite bus bar reaches requirement.But for high-frequency alternating current occasion, because of kelvin effect impact, electric current mainly concentrates on conductive surface, and inside is CURRENT DISTRIBUTION seldom, will make the conductive surface electric current excessive and generate heat.Each extremely generally all is to be made of one deck copper coin for existing composite bus bar, because there is kelvin effect in the high-frequency alternating electric current, most of electric current trend copper coins surface, only there is seldom electric current in the middle of the copper coin, the surface is owing to large gathering of electric current generated heat, and actual copper plate thickness does not play the effect of Uniform Dispersion electric current.Application number is that 201120518930.8 utility model patent discloses a kind of aluminium alloy compound busbar, each utmost point of this busbar is a monoblock aluminium alloy plate, cause electric current to concentrate on the aluminium alloy plate surface because of kelvin effect easily equally, make the aluminium alloy plate surface current excessive and generate heat.Therefore, be badly in need of a kind of novel composite bus bar of exploitation and solve electric current kelvin effect problem, reduce composite bus bar in the caloric value of high frequency occasion, make it reach stable condition of work.According to the generation principle of kelvin effect, the composite bus bar copper coin can be processed into and hollowly replace existing whole thick copper coin structure, but hollow copper coin difficulty of processing is larger, follow-up manufacturing process also is difficult to realize.
On the other hand, along with electric and electronic power is increasing, the composite bus bar copper coin is more and more thicker, the harder and bad processing of thick copper coin, and its processing dimension often is difficult to satisfy high-precision installation requirement.
Summary of the invention
Technical problem to be solved in the utility model is for the prior art deficiency, to provide a kind of one pole multilayer composite bus row easy to process, solution high frequency occasion composite bus bar heating problem, reduction composite bus bar rigidity.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of one pole multilayer composite bus row, comprise insulating barrier, conductor row and tack coat, described conductor row is composited by described tack coat bonding by the some identical metal sheets of thickness.
As preferred version, described forming angle radian R＞2t, wherein t is described insulating barrier, conductor row and the tack coat thickness after superimposed.
Can conductor row two sides stack unification layer insulating be carried out hot pressing according to needs are installed, bending and molding is that the forming angle radian is the three-dimensional structure of R after the hot pressing.
The utility model is by with each utmost point copper coin of busbar or aluminium alloy plate by some thinner copper coins (for example, originally to adopt the copper coin of 1 layer of 2mm thickness as a utmost point, the substitute is, copper coin stack with 4 0.5mm) stacks up, make every one deck balanced current distribution, electric current can both reach equally distributed effect in a whole utmost point copper coin relatively, has avoided busbar because high-frequency produces kelvin effect and has caused busbar surface problems of excessive heat.
On the one hand, the multi-layer thin copper coin replaces whole thick copper coin or aluminium alloy plate, has reduced the rigidity of busbar in addition, is more conducive to install connect.
As preferred version, described metal sheet is a kind of in copper plate, aluminium sheet, the brass sheet.
Compared with prior art, the beneficial effect that the utility model has is: the utility model is superimposed as conductor row with the polylith metal sheet, make the balanced current distribution on each piece metallic plate, avoided busbar because high-frequency produces kelvin effect and caused the overheated problem in busbar surface; The multi-layer thin metallic plate replaces whole thick sheet metal, has reduced the rigidity of busbar, is more conducive to install connect; After being shaped to three-dimensional structure, its employed mould is simple, and production efficiency is high, is fit to produce in enormous quantities.

Embodiment
As shown in Figure 1-Figure 3, the utility model one embodiment comprises insulating barrier 1,9, conductor row and tack coat 3,5,7, described conductor row is composited by described tack coat bonding 3,5,7 by the identical metal sheets 2,4,6 of some thickness, 8, described conductor row two sides stack unification layer insulating 1,9 rear hot-forming be the three-dimensional structure of R for the forming angle radian.Forming angle radian R＞2t, wherein t is described insulating barrier, conductor row and the tack coat thickness after superimposed.
Metal sheet can be copper plate, aluminium sheet or brass sheet.
Bonding being assembled into together of composite bus bar of the present utility model more than two can be used, to satisfy the different demands of different occasions.
