Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
104 words
In a converter having series connected thyristors assembled, together with circuit components, in a framework containing a plurality of support columns, wherein the improvement comprises support columns having: a. at least one carrier in the form of a cup with a plurality of flat side surfaces and a bottom in each column; b. vertical support elements of an electrical insulating material making up a portion of each column; c. screws connecting said carriers to said vertical support elements; and d. at least one of the carriers being made of electrically conducting material and being connected in the series circuit so as to carry current.
Claim 2
Dependent Claim
104 words
In a converter having series connected thyristors assembled, together with circuit components, in a framework containing a plurality of support columns, wherein the improvement comprises support columns having: a. at least one carrier in the form of a cup with a plurality of flat side surfaces and a bottom in each column; b. vertical support elements of an electrical insulating material making up a portion of each column; c. screws connecting said carriers to said vertical support elements; and d. at least one of the carriers being made of electrically conducting material and being connected in the series circuit so as to carry current.
Claim 3
Dependent Claim
15 words
A converter according to claim 1 wherein each carrier is of an essentially square shape.
Claim 4
Dependent Claim
41 words
A converter according to claim 2 wherein the inside surfaces of the sidewalls of the carriers are tapered such that the cross section of the cup is greater at the edge of the cup than at the bottom of the cup.
Claim 5
Dependent Claim
57 words
A converter according to claim 1 wherein the series connected thyristors are divided into groups disposed in several levels one on top of each other and wherein each support column has a carrier for each level with the carriers of each support column mechanically coupled to each other through said vertical support elements of electrically insulating material.
Claim 6
Dependent Claim
15 words
A converter according to claim 4 wherein each carrier is of an essentially square shape.
Claim 7
Dependent Claim
41 words
A converter according to claim 5 wherein the inside surfaces of the sidewalls of the carriers are tapered such that the cross section of the cup is greater at the edge of the cup that at the bottom of the cup.
Claim 8
Dependent Claim
12 words
A converter according to claim 6 wherein said carriers are metal castings.
Claim 9
Dependent Claim
25 words
A converter according to claim 1 and further including coupling between the current carrying carriers and circuit components, said couplings being made with screw connection.
Claim 10
Dependent Claim
26 words
A converter according to claim 8 wherein fuses are provided in said converter and wherein at least one current carrying carrier is coupled to said fuses.
