摘要: |
本文基于三通道扭曲堆叠导体和准各向同性导体, 提出了三通道准各向同性导体. 在有限元仿真软件中使用自洽模型对两种导体进行建模, 分析并对比了两种三通道导体的临界电流、 临界电流各向异性、 工程电流密度与导体半径之间的关系. 仿真结果表明三通道准各向同性导体在背景场条件下具有使用价值, 同时也为提高两种三通道导体工程电流密度提出了建议。 |

Abstract: |
Based on 3-channel twisted stacked-tape cable conductor and quasi-iso tropic strand, this paper proposes 3-channel quasi-isotropic conductor. These kinds of conductors were modeled using self-consistent models in the finite element simulation software, and the relationships between the critical current, critical current anisotropy, engineering current density and conductor radius of the two 3-channel conductors were analyzed and compared. The simulation results show that the 3-channel quasi-isotropic conductor is useful under background field conditions, and it is also proposed to improve the engineering current density of these 3-channel conductors. |
