摘要：

A superconducting (SC) current feeder system for LHD has been operated since March of 1998, It consists of 9 SC bus-lines, 9 pairs of current leads and 3 current lead cryostats. SC bus-lines have a total length of 497 m, rated current of 32 kA and withstand voltage of 5 kV under 77 K helium gas condition. After 2 fears operation of this system it was demonstrated that the SC current feeder system is reliable and useful. On the basis of these operational experiences we have evaluated performance, reliability, and operation cast of the SC current feeder system in comparison with non-SC type current feeder system. We have concluded that the SC current feeder system with high current capacity is more suitable than other current feeder systems such as using water-cooled bus bar, especially for large-scale SC fusion experimental devices.
