Embodiment
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, the embodiments of the present invention are explained in detail.But, persons of ordinary skill in the art may appreciate that in each execution mode of the present invention, proposing many ins and outs to make reader understand the application better.But, even without these ins and outs with based on the many variations of following execution mode and amendment, each claim of the application technical scheme required for protection also can be realized.
First embodiment of the invention relates to a kind of laminated bus bar, such as, be copper bar or aluminium row.As shown in Figure 1, laminated bus bar 1 comprises body 10, efferent 11 and two electric capacity C1, C2.Efferent 11 is extended out by a side of body 10, and the edge of the edge of efferent 11 and body 10 forms two point of interfaces E1, E2.Efferent 11 in present embodiment and body 10 are mutually vertical, that is, two point of interfaces E1, E2 are intersecting vertically a little of the edge of efferent 11 and the edge of body 10, but present embodiment does not impose any restrictions this.
In present embodiment, each electric capacity has positive pole, negative pole and a central point, and central point is the positive pole of this electric capacity and the mid point of negative pole line.Two electric capacity C1, C2 are arranged at body 10, and the central point of each electric capacity is positioned at (namely two electric capacity are positioned at same row) on same level line, and this horizontal line is electric capacity neutrality line M.But present embodiment does not impose any restrictions the concrete number of electric capacity and arrangement mode, multiple electric capacity also can be arranged in different row, and the multiple electric capacity often arranged are positioned on identical electric capacity neutrality line.Electric capacity neutrality line M is parallel to the edge of body and perpendicular to vertical direction line D, two electric capacity C1, C2 are arranged at the left and right sides of this vertical direction line D respectively symmetrically.Efferent 11 in present embodiment is perpendicular to body 10, and namely the outbound course of efferent is vertical direction, but present embodiment does not impose any restrictions this, and the outbound course of efferent also can be not orthogonal to body.
In present embodiment, E1 is comparatively near for electric capacity C1 distance point of interface, and therefore, the line of the central point F1 of point of interface E1 and electric capacity C1 is the capacitance direction line D1 of electric capacity C1, and the positive pole of electric capacity C1 and negative pole lay respectively on this capacitance direction line D1.That is, the positive pole of point of interface E1, electric capacity C1, the negative pole of electric capacity C1 are arranged in order on this capacitance direction line D1.In like manner, E2 is comparatively near for electric capacity C2 distance point of interface, and therefore, the line of the central point F2 of point of interface E2 and electric capacity C2 is the capacitance direction line D1 ' of electric capacity C2, and the positive pole of electric capacity C2 and negative pole lay respectively on this capacitance direction line D1 '.That is, the positive pole of point of interface E2, electric capacity C2, the negative pole of electric capacity C2 are arranged in order on this capacitance direction line D1 '.
