First Claim
Patent Images
1. A high power bulk power processing rectifier comprising:
- a plurality of components to be interconnected including, high power ferro transformers, inductors, capacitors and interconnecting current carrying busses;
the components including conductor connection bolts to which current carrying conductors are attached to interconnect at least two components;
the at least two components having the conductor connection bolts of each component of the at least two components occurring on different planar levels from each other;
wherein the improvement comprises;
at least one flexible bus bar interconnecting the at least two components,the flexible bus bar comprising a selected number greater than one of thin conducting leaves stacked on top of and directly contiguous to each other providing sufficient current carrying cross section and each thin conducting leave having a first and second pair of apertures located at opposite ends of each leave, respectively, to facilitate bolt connections to the conductor connection bolts;
all of the thin conducting leaves of the flexible bus bar being bolted through the paired apertures at each end to the at least two components each having a connection location which lie in differing planes with respect to each other,the flexible bus bar flexing and assuming a bending non planar contour when bolted to differing planes of the connection locations of the at least two components.

Abstract
A bus bar comprised of a layered stack of flexible conductive planar leaf conductors, with sufficient cross-sectional current carrying capacity, is used in a bulk rectifier for conducting heavy currents between components. The bus bar is amenable to being easily coupled to mounting structures having mounting pad planes at different levels and angular positions. It is normally uninsulated and hence heat exchange is enhanced compared with traditional insulated cable. This permits the bus bars to operate at a relatively low temperature.

6. A high power bulk power processing rectifier comprsing:
-
a supporting cabinet including a first and second ferro transformer having conductor connection apparatus and being located in a bottom of the cabinet, a plurality of inductors in a top portion of the cabinet each having conductor connection apparatus, and a central bus ascending vertically in the cabinet, first and second flexible bus bars for connecting the conductor connection apparatus of the ferro transformers to the central bus, and third and fourth flexible bus bars for connecting the conductor connection apparatus of the inductors to the central bus; wherein each flexible bus bar includes; a plurality of thin conducting leaves stacked on top of and directly contiguous to each other and having a sufficient number of individual thin conducting leaves to attain a desired current carrying total cross section and having a a first and second pair of apertures located at opposite ends of each leaf, respectively, to facilitate bolt connections to the conductor connection apparatus of the ferro transformers and to the conductor connection apparatus of the inductors and to the central bus by bolt mechanisms, the first, second, third and fourth flexible bus bars being connected to the central bus and to the first and second ferro transformers, and the first and second inductors respectively, and all of the thin conducting leaves at each of the first, second, third and fourth flexible bus bars are each dedicated to connecting two end locations, and the leaves deformed by the connection into a non planar profile. - View Dependent Claims (7, 8, 9, 10)
