Underground Modular High-Voltage Direct Current Electric Power Transmission System

摘要: High capacity (10 GW, for example) passively cooled non-superconducting underground high voltage direct current electric power transmission lines (100) of very low loss (1% per 1,000 km, and competitive cost. The include segment modules (101) linked together with compliant splice (102) between the segments (101), typically installed in a protective conduit (103). relatively rigid pipe- shaped conductors (117) insulated by pipe-like solid insulating layers (131) to form that resemble pipe. are through radially axially line (100). There preferably wheels (300) deployed ease insertion removal assembled into (103), center each module within and/or provide motive force braking allow be on slope.
