Problems solved by technology

[0002] In the existing field of conversion, laminated busbars are widely used due to their advantages of low inductance and low impedance. During use, the connection between laminated busbars or the connection between busbars and external input and output ends They are all connected through a single thicker copper plate, copper rod profile or flexible unipolar copper bar. However, when using the above connection method, a large inductance will be generated between the two poles, and the connection of the copper plate or copper r

Example Embodiment

[0017] Examples:

[0018] Such as figure 2 As shown, the flexible laminated bus bar described in this embodiment includes a positive copper bar 1, a negative copper bar 2, a butterfly gasket 7 connecting the two copper bars, and a modified screw 3, such as Figure 4 As shown, the positive copper bar 1 and the negative copper bar 2 are all composed of a plurality of flaky copper plates 8 superimposed and combined, and each group of flaky copper plates 8 is fixed and connected by a modified screw 3 to form the required copper bar. A butterfly washer 7 is provided on the connecting surface of the screw 3 and the copper bar, and a busbar connection mounting hole 4 is opened on the surface of the positive copper bar 1 and the negative copper bar 2 oppositely. The busbar connection mounting hole 4 is used for connection The laminated bus bar 5, the positive copper bar 1 and the negative copper bar 2 are relatively superposed and bonded, and the outer surface of the positive copper bar...

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 [0001] The invention relates to a laminated busbar structure, in particular to a flexible laminated busbar for mutual connection of laminated busbars or flexible connection of input ends and output ends. Background technique [0002] In the existing field of conversion, laminated busbars are widely used due to their advantages of low inductance and low impedance. During use, the connection between laminated busbars or the connection between busbars and external input and output ends They are all connected through a single thicker copper plate, copper rod profile or flexible unipolar copper bar. However, when using the above connection method, a large inductance will be generated between the two poles, and the connection of the copper plate or copper rod profile is a hard link, and the shock resistance is poor. , frequent thermal expansion, easy to cause problems such as loose connection, poor contact, etc. In addition, the heat dissipation area of ​​a single ...
