Claims
- 1. A gas-insulated transmission line, comprising:
- (A) a corrugated outer conductor;
- (B) an inner conductor adapted for connection to an energizing source and disposed interiorly in said outer conductor;
- (C) an insulating gas disposed within the annular space between said outer and inner conductors;
- (D) insulating means disposed between said outer and inner conductors for insulatingly supporting said inner conductor within said outer conductor;
- (E) particle trapping means disposed proximate the inner periphery of said corrugated outer conductor for trapping particles, said particle trapping means having the capability of moving relative to said corrugated outer conductor;
- (F) rotatable attachment means affixed to said particle trapping means in a disposition of electrical continuity therewith and having a rotatable portion thereof which is rotatable on a pivot support axis disposed parallel to the direction of travel of said inner conductor;
- (G) a lever arm fixedly disposed upon said rotatable portion for being angularly moved in correspondence with rotation of said rotatable portion;
- (H) a non-binding electrical contact piece disposed on said lever arm for making non-binding electrical contact with the inner surface of said corrugated outer conductor; and
- (I) biasing means for biasing said electrical contact piece against said inner surface of said corrugated outer conductor to maintain electrical continuity between said corrugated outer conductor and said particle trapping means regardless of the axial position of said particle trapping means relative to the corrugations of said corrugated outer conductor.
- 2. The gas-insulated transmission line of claim 1 wherein the electrical contact piece is a metal roller.
- 3. The gas-insulated transmission line of claim 1 wherein said lever arm is disposed parallel with the direction of said corrugations of said corrugated outer conductor.
