Abstract
Abstract An encapsulated high voltage-switching installation, the cylindrical conductor of which serves to carry a high voltage and is surrounded by a grounded cylindrical sheath filled with an insulating gas. The conductor is concentrically attached within the sheath by means of insulating supports. According to important aspects of this invention at least one trumpet-shaped foil possessing a rotationally symmetrical construction and widening in the axial direction of the conductor is arranged between the conductor and the sheath, this trumpet-shaped foil being formed of an insulating material.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
69 words
An encapsulated high voltage-switching installation comprising a cylindrical conductor intended to carry a high voltage, a grounded cylindrical sheath filled with an insulating gas surrounding said conductor, insulating support means for concentrically connecting said conductor with said sheath, and at least one rotationally symmetrical substantially trumpet-shaped foil formed of insulating material arranged between said conductor and said sheath, said trumpet-shaped foil widening in the axial direction of the conductor.
Claim 2
Dependent Claim
69 words
An encapsulated high voltage-switching installation comprising a cylindrical conductor intended to carry a high voltage, a grounded cylindrical sheath filled with an insulating gas surrounding said conductor, insulating support means for concentrically connecting said conductor with said sheath, and at least one rotationally symmetrical substantially trumpet-shaped foil formed of insulating material arranged between said conductor and said sheath, said trumpet-shaped foil widening in the axial direction of the conductor.
Claim 3
Dependent Claim
69 words
An encapsulated high voltage-switching installation comprising a cylindrical conductor intended to carry a high voltage, a grounded cylindrical sheath filled with an insulating gas surrounding said conductor, insulating support means for concentrically connecting said conductor with said sheath, and at least one rotationally symmetrical substantially trumpet-shaped foil formed of insulating material arranged between said conductor and said sheath, said trumpet-shaped foil widening in the axial direction of the conductor.
Claim 4
Dependent Claim
69 words
An encapsulated high voltage-switching installation comprising a cylindrical conductor intended to carry a high voltage, a grounded cylindrical sheath filled with an insulating gas surrounding said conductor, insulating support means for concentrically connecting said conductor with said sheath, and at least one rotationally symmetrical substantially trumpet-shaped foil formed of insulating material arranged between said conductor and said sheath, said trumpet-shaped foil widening in the axial direction of the conductor.
Claim 5
Dependent Claim
44 words
An encapsulated high voltage-switching installation as defined in claim 1, wherein the same creepage path lengths are selected by appropriate curvature of the surface of said foil for the same electrical potential differentials determined from the field pattern between the conductor and the sheath.
Claim 6
Dependent Claim
40 words
An encapsulated high voltage-switching installation as defined in claim 2, wherein said insulating support means comprises a disc-shaped insulation support member, and wherein said trumpet-shaped foil at the end thereof having the largest opening bears against said insulation support member.
