Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
175 words
An angle transition joint for a gas-insulated power transmission system; said power transmission system comprising first and second bus conductors, first and second outer conductive housings enclosing said first and second bus conductors, respectively, first and second insulator support means supporting said first and second bus conductors coaxially within said first and second outer conductive housings, respectively, and high pressure dielectric gas filling the interior of said first and second outer conductive housings; said first and second bus conductors being straight and having axes which intersect one another at an angle other than 180*; said tansition joint comprising a generally cylindrical conductive strip of constant width and a bus connection means having a smooth outer surface and extending between the opposing ends of said first and second bus conductors; said first and second outer housings having spaced coplanar edges which each form an angle relative to their respective axes which is other than 90*; said cylindrical strip connected at either side to and extending around the spaced coplanar edges of said first and second housings.
Claim 2
Dependent Claim
175 words
An angle transition joint for a gas-insulated power transmission system; said power transmission system comprising first and second bus conductors, first and second outer conductive housings enclosing said first and second bus conductors, respectively, first and second insulator support means supporting said first and second bus conductors coaxially within said first and second outer conductive housings, respectively, and high pressure dielectric gas filling the interior of said first and second outer conductive housings; said first and second bus conductors being straight and having axes which intersect one another at an angle other than 180*; said tansition joint comprising a generally cylindrical conductive strip of constant width and a bus connection means having a smooth outer surface and extending between the opposing ends of said first and second bus conductors; said first and second outer housings having spaced coplanar edges which each form an angle relative to their respective axes which is other than 90*; said cylindrical strip connected at either side to and extending around the spaced coplanar edges of said first and second housings.
