Abstract
Abstract A high-power converter of the type where converter rectifiers and fuses are mounted on bus bars in which at least a portion of the bus bar structure is attached in a self-supporting manner on a base frame through at least one insulating spacer, the bus bar thus forming a frame for the complete converter structure including necessary enclosures thereby making it possible to eliminate otherwise customary, relatively expensive frame structures used in converter arrangements.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
136 words
A high power converter of the type wherein converter elements and fuses are mounted on bus bars comprising: a. a rectangular base frame; b. a positive DC bus bar; c. a negative DC bus bar; e. first means for insulating attaching said positive DC bus bar in a self supporting manner to one of the long sides of said base frame; f. second means for insulating attaching said negative DC bus bar in a self supporting manner to the other long side of said base frame, said DC bus bars forming a supporting frame work for the complete converter structure including enclosures; g. a plurality of AC bus bars fastened only to said DC bus bars; h. insulating layers separating each of said AC bus bars from said DC bus bars to which they are attached.
Claim 2
Dependent Claim
136 words
A high power converter of the type wherein converter elements and fuses are mounted on bus bars comprising: a. a rectangular base frame; b. a positive DC bus bar; c. a negative DC bus bar; e. first means for insulating attaching said positive DC bus bar in a self supporting manner to one of the long sides of said base frame; f. second means for insulating attaching said negative DC bus bar in a self supporting manner to the other long side of said base frame, said DC bus bars forming a supporting frame work for the complete converter structure including enclosures; g. a plurality of AC bus bars fastened only to said DC bus bars; h. insulating layers separating each of said AC bus bars from said DC bus bars to which they are attached.
Claim 3
Dependent Claim
36 words
A high-power converter according to claim 1 and further including at least one bulkhead partition arranged between the bus bars of opposite polarity, said bulkhead partition being fastened to the bus bars on only one side.
Claim 4
Dependent Claim
22 words
A heavy duty converter according to claim 2 and further including insulating supports attached between the DC bus bars of opposite polarity.
Claim 5
Dependent Claim
33 words
A heavy duty converter according to claim 3 and further including an insulating bar attached to said DC bus bars of one polarity transversely to the longitudinal axis of said DC bus bars.
Claim 6
Dependent Claim
21 words
A heavy duty converter according to claim 4 and further including at least one enclosure surface attached to said insulating bar.
Claim 7
Dependent Claim
25 words
A heavy duty converter according to claim 5 wherein a plurality of DC bus bars of one polarity are combined into a common bus bar.
Claim 8
Dependent Claim
17 words
A heavy duty converter according to claim 6 wherein said bus bar is of an E-shaped design.
Claim 9
Dependent Claim
61 words
A heavy duty converter according to claim 7 wherein the three lug-shaped ends of each E-shaped DC bus bar are each associated with one of the three phases of a three-phase system with the AC bus bar associated with a corresponding phase attached to said lug-shaped end and further including converter elements and fuses attached to each of said lug-shaped ends.
Claim 10
Dependent Claim
27 words
A heavy duty converter according to claim 8 and further including cooling fins on one side of each bus bar to which a converter element is mounted.
Claim 11
Dependent Claim
39 words
A heavy duty converter according to claim 9 wherein said AC bus bars are fastened to said DC bus bars approximately at right angles thereto and further including means insulating said AC bus bars from said DC bus bars.
Claim 12
Dependent Claim
80 words
A heavy duty converter according to claim 10 wherein each of said DC bus bars is fastened to one side of the crosspiece of a beam having a T cross section, the stem of said T being attached by said insulating spacers to said base and further including bus bars for taking off current fastened to the other side of the crosspiece of said T and wherein said DC bus bar is free of cooling fins in the attachment area.
Claim 13
Dependent Claim
27 words
A heavy duty converter according to claim 11 and further including means arranged in cooperation with said DC bus bars to form a plurality of air shafts.
