Abstract
The invention discloses a flexible laminated bus bar, comprising positive and negative pole copper bars, high-temperature resistant epoxy dielectric films, butterfly-shaped gaskets and improved bolts, wherein the positive and negative pole copper bars are formed by laminating high-flexibility thin copper plates and can reduce inductance between the positive pole and the negative pole compared with a flexible monopole copper bar or a thicker single copper plate; the soft connection of the flexible laminated bus bar can be used to improve the shockproof performance of the connection and eliminate the influences of thermal expansion on connection looseness; and the cooling area of the flexible laminated bus bar is enlarged greatly, thus the larger current can flow through the flexible bus bar, thereby strengthening the utilization rate of the copper plates and saving the resources.
Description
Technical field
The present invention relates to a kind of laminated bus bars structure, be specifically related to a kind ofly be used for that laminated bus bars interconnects or a kind of flexible overlapping bus row that input, output flexibly connect.
Background technology
In existing unsteady flow field, laminated bus bars is because its low inductance, advantages such as Low ESR are widely adopted, in use, connection between the laminated bus bars or bus row and outside input, the connection of output all is by single thicker copper coin mostly, copper rod section bar or flexible one pole copper bar connect, but when stating connected mode in the use, two interpolars can produce bigger inductance, and the connection of copper coin or copper rod section bar belongs to hard link, shock resistance is poor, thermal expansion is frequent, easily cause to connect and become flexible, problems such as loose contact, in addition, single copper coin or flexible one pole copper bar area of dissipation are less, poor radiation, from current-carrying, also greatly reduce the utilance of copper material, so the laminated bus bars that needs a kind of flexibility improving switching performance, and effectively reduces the inductance of two interpolars.
Summary of the invention
The object of the invention is to provide a kind of flexible overlapping bus row, and it can reduce inductance between conductor the two poles of the earth, improves the degree of flexibility of stack bus bar, improve the copper material utilance.
In order to solve these problems of the prior art, technical scheme provided by the invention is:
A kind of flexible overlapping bus row, butterfly pad and transformation of the way screw that it comprises anodal copper bar, negative pole copper bar and connects two copper bars, described anodal copper bar, negative pole copper bar form by plurality of thin sheet copper coin stack combinations, described butterfly pad, transformation of the way screw connect thin slice copper coin group, and described anodal copper bar, negative pole copper bar offer busbar connection hole.
Detailed technical scheme: a kind of flexible overlapping bus row, butterfly pad and transformation of the way screw that it comprises anodal copper bar, negative pole copper bar and connects two copper bars, described anodal copper bar, negative pole copper bar form by plurality of thin sheet copper coin stack combinations, described butterfly pad, transformation of the way screw connect thin slice copper coin group, described anodal copper bar, negative pole copper bar offer busbar connection hole, the outer surface of described anodal copper bar, negative pole copper bar has sticked dielectric film, and described laminar copper coin is the high flexibility sheet copper.
With respect to scheme of the prior art, advantage of the present invention is:
1. flexible overlapping bus described in the invention row is by anodal copper bar, negative pole copper bar and the butterfly pad that connects two copper bars, and transformation of the way screw constitutes.Compare the inductance that can effectively reduce by two interpolars with single thicker copper coin or flexible one pole copper, and being flexible coupling of flexible overlapping bus row can improve the shock resistance of connection, eliminate thermal expansion to connecting loosening influence, and this flexible overlapping bus row has improved the area of dissipation of copper bar greatly, make this copper bar can pass through bigger electric current, increase the utilance of copper coin, reduced the waste of resource;
2. flexible overlapping bus row provided by the present invention connects laminated bus bars, structure is very compact, it not only can possess characteristics such as normal stack bus row's Low ESR, low inductance, and can reduce system noise and electromagnetic interference and radio frequency interference, realize flexibly connecting and do not have thermal expansion and be connected between laminated bus bars, improved connective stability.
