Abstract
A gas insulated transmission line having an inner conductor disposed within a cylindrical outer sheath. A spacer assembly for supporting the transmission line comprises two members which fit over the inner conductor and which together surround the inner conductor. The two members are secured together by a curved plate, and the entire assembly can be disposed within the outer sheath to support the inner conductor within the outer sheath. The material of which the two members are made is preferably a material having a relative permittivity less than approximately 3.7. The two members together in cross section can be disc-shaped or conically-shaped.
Claims10
A gas insulated transmission line comprising:
- an elongated, cylindrical inner conductor disposed within said outer sheath, said inner conductor having a radial outer radius;
- an insulating gas disposed within said outer sheath, said insulating gas electrically insulating said inner conductor from said outer sheath;
- and
- at least one spacer assembly disposed within said outer sheath, said spacer assembly insulatably supporting said inner conductor within said outer sheath, said spacer assembly comprising:
- a first member having a radial shape defined along its radial extremities by an inner radius substantially the same as said inner conductor outer radius and by an outer radius being substantially the same as said outer sheath inner radius, said first member along its inner radial extremity extending for an arc distance of 180.degree., said first member being disposed intermediate said inner conductor and said outer sheath, said first member inner radial extremity being positioned adjacent said inner conductor, said first member having a pair of cavities therein extending inwardly from said outer radial extremity;
- a second member having a radial shape defined along its radial extremities by an inner radius substantially the same as said inner conductor outer radius and by an outer radius less than said outer sheath inner radius, said second member being disposed intermediate said inner conductor and said outer sheath, said second member inner radial extremity extending for an arc distance of 180.degree. and being positioned adjacent said inner conductor, said first and second member outer radial extremities together extending for an arc distance of 360.degree.;
- and
- a curved plate having inner and outer radial extremities defined by an inner radius substantially the same as said second member outer radius and by an outer radius substantially the same as said outer sheath inner radius, said plate being positioned intermediate said second member and said outer sheath, said plate having an inwardly projecting nub at each circumferential end thereof, said plate circumferentially extending beyond said second member outer radial extremity to said first member cavities such that said nubs are disposed within said first member cavities, said plate securing said first member to said second member.
