管内电缆导体传输交流损耗的理论计算和实验
Theoretical and Experimental Study on Transport Current Loss for Cable-in-Conduit Conductors
摘要
Abstract
For practical applications of large superconducting nuclear fusion experimental devices,such as international thermonuclear experimental reactor and China fusion engineering test reactor,AC Joss is the main criteria on the stability performance.Considering the numerical calculation on transport AC loss of NbTi/Nb3Sn-based strands and cable-in-conduit conductors (CICCs) for nuclear fusion magnets was rarely presented before,a distributed parameter equivalent circuit model of N-strands conductors for current analysis was investigated.Based on the current distribution of the whole cable,the transport current loss was calculated.Meanwhile,the results were compared to the critical state (CS) model to verify the feasibility of the proposed model.Finally,an improved experimental system was proposed,which gives a good reference for next step CICC cables and coils measurement.Further,a scaling law of single strand was obtained,which lays the foundation of transport current loss calculation for CICCs.关键词
