With reasonable structure, convenient installation and maintenance, the utility model can facilitate the modularization and the systematization of the design of an electronic deflector for the electric power.
Description
Technical field
The utility model is applied in the electronic power conversion device, uses as device for power switching electrical communications conducting medium.
Background technology
At present, the composite bus bar of widespread usage generally is incorporate overall structure in convertor assembly.When convertor assembly power was big, the composite bus bar area was also bigger, had brought very big difficulty for design, manufacturing and installation.Simultaneously overall structure type composite bus bar also is unfavorable for installing and maintenance, especially when composite bus bar and device for power switching binding post are electrically connected, install and tend to take place a lot of problems, even appearance such as can't install at phenomenon.
Summary of the invention
The purpose of this utility model is in order to solve the difficulty of monolithic devices composite bus bar at aspects such as manufacturing and installations, and partly have very strong symmetry and unit homogeny at Power Conversion in the convertor assembly, adopted the design of carrying out combined busbar according to cellular construction.Because unit composite bus bar area is less, is easy to design, makes and installs.Particularly when the Power Conversion cellular construction is identical, can adopt identical composite bus bar, this just more can fully demonstrate superiority of the present utility model.This combined busbar is when assembling, and available appropriate interface couples together each unit composite bus bar and forms a complete composite bus bar, and this kind structure can also be eliminated alignment error and Installation Stress.
Technical solution of the present utility model is achieved in that and employedly in a kind of convertor assembly is electrically connected combined busbar, form by a plurality of unit composite bus bar, with the unit composite bus bar by connecting plate and bolt with the plane be connected, the monocline face connects, the mode a kind of or its combination of double inclined plane in connecting is connected with each other.Interface on the aforementioned single composite bus bar is the part of turning back that its marginal portion is formed through two 90 degree bendings, and the busbar interface of different layers is spaced from each other certain distance, bends up at different positions, should be consistent with the interface surface height of one deck busbar.Should have ellipse hole on the described return, long axis direction is consistent with the closure of composite bus bar.The interface connected mode of described unit composite bus bar has three kinds: the mode of a kind of or its combination in plane connected mode, monocline face connected mode and the double inclined plane.
Compare with existing monolithic devices composite bus bar, the combined busbar that the utility model proposes, overcome the former manufacture and design and installation aspect the problem that exists, made things convenient for I﹠M, reduce product cost, helped the modularization and the seriation design of convertor assembly.

Embodiment
As shown in the figure, that uses in a kind of converter device is electrically connected combined busbar, form by a plurality of unit composite bus bar, be connected with the plane by connecting plate 4 and bolt 5, the monocline face connects, mode a kind of or its combination during double inclined plane connects is connected with each other, interface 6 on the aforementioned unit composite bus bar is turn back part (its structure such as Fig. 1 that its marginal portion is formed through two 90 degree bendings, be example only among the figure with two layers, down together) the busbar interface of different layers is spaced from each other certain distance, bend up at different positions, should be consistent with the interface surface height of the busbar of one deck.
When combined busbar is assembled, the connected mode of unit composite bus bar as shown in Figures 2 and 3, therefrom can see, two unit composite bus bars will couple together with the busbar of one deck with connecting plate 4 and bolt 5 at interface 6 places, make it to form conductive path, the connecting plate size is consistent with this layer busbar interface.Combined busbar need satisfy certain electric property requirement for connecting the conducting medium of the device for power switching in the convertor assembly.Every layer of busbar can have a plurality of interfaces, and the interface of different layers will be interspersed, to reach the equally distributed purpose of electric current.The width of each interface (size of a among Fig. 1) will be selected suitably, and promptly every layer interface width sum will satisfy the requirement of this layer current load.Distance (size of the b among Fig. 1) between two interfaces will satisfy the requirement of two layers of needed clearance for insulation of potential difference.In order to increase the insulation property of interlayer, insulating barrier will extend the conducting medium edge certain-length of not bearing interface task, is as the criterion can satisfy creepage distance.Shown in A-A view among Fig. 1 and B-B view.
The connected mode of unit composite bus bar has three kinds: plane connected mode (as shown in Figure 2), monocline face connected mode (as shown in Figure 4) and double inclined plane connected mode (as shown in Figure 5).The occasion that guarantees precision for mounting plane easily adopts the plane connected mode; The occasion that is difficult to satisfy required precision for mounting plane adopts monocline face connected mode or double inclined plane connected mode, adopts the inclined-plane connected mode can eliminate scale error on the vertical mounting plane direction within the specific limits.
The interface connecting plate perforate of composite bus bar (installing and fixing bolt uses) is oval (as shown in Figure 1), and elliptical aperture can be eliminated three layers of alignment error on the composite bus bar direction.
Every layer of conducting medium can be divided into positive pole and negative pole as an electrode as two layers of composite bus bar; Three layers of composite bus bar can be divided into positive pole, negative pole and a cross streams; Other multilayer composite bus row principles are identical.
