Performance of a technical and economical feasibility study of an HVDC compressed gas insulated transmission line. [600 kV]

Technical Report ·
OSTI ID:6706492
Progress in evaluating the technical feasibility of gas-insulated cables and circuit breakers for HVDC systems (600 kV) is reported. Investigations with a model cable resulted in cautious optimism that it will be possible to commission the total length of an installed cable with HVDC. The major problem is to prevent the insulators from being contaminated by residual particles. The model cable was used to test a new design principle that particles moving towards the insulator can be directed toward a shield on the conductor adjacent to the insulator and be confined at the end edges of the shield. Then they can be trapped and retained inside a particle trap at the bottom of each bulge. Results showed that all metal particles can be moved out of a 2 ft length of enclosure in minutes, and that no particles were seen on or in the vicinity of the insulator. Specific plans for accelerating this project are outlined. (LCL)
