Claims
- 1. A gas-insulated transmission line comprising:
- an elongated, hollow outer sheath;
- an elongated inner connector at high potential with respect to said outer sheath disposed within said outer sheath;
- an insulating gas electrically insulating said inner conductor from said outer sheath;
- an insulating spacer insulatably supporting said inner conductor within said outer sheath; and
- a longitudinally-extending particle-trapping ring secured to said spacer and extending longitudinally-outwardly therefrom, said particle-trapping ring being spaced-apart from said outer sheath and said inner conductor, said particle-trapping ring comprising a central portion adjacent said spacer having a first, fixed diameter and two tapering end portions extending longitudinally-outwardly from opposite longitudinal ends of said central portion and radially-inwardly towards a second diameter less than said first diameter.
- 2. The gas insulated transmission line according to claim 1 including a plurality of insulating spacers and a plurality of particle-trapping rings with a particle-trapping ring being secured to each insulating spacer, said particle-trapping rings being disposed longitudinally adjacent to each other.
- 3. The transmission line according to claim 2 wherein said outer sheath and said inner conductor are disposed along an arc.
- 4. The transmission line according to claim 1 wherein said outer sheath is corrugated.
- 5. The transmission line according to claim 1 wherein said particle-trapping ring is of one integral piece.
- 6. The transmission line according to claim 5 including a toroid secured at the longitudinal end of each of said two tapering end portions.
- 7. The transmission line according to claim 1 wherein said particle-trapping ring is comprised of said two tapering end portions being welded to said central portion.
