摘要/Abstract

摘要： CFETR馈线导体设计采用NbTi超导线材管内电缆(CICC)结构，其中超导电缆主要由6个花瓣形状的电缆和一个中间铜芯绞制而成，而花瓣形状的电缆由NbTi超导线材与铜线沿顺时针方向通过4级绞制而成，导体外部采用不锈钢铠甲结构。计算分析了运行工况下导体结构的热稳定性参数。结果显示，在95.6kA的最高载流下，分流温度低于6K，热点温度低于250K，满足设计要求。

关键词: CFETR馈线导体, 热稳定性, 分流温度

Abstract: The structure of feeder conductor is designed as a cable in conduit conductor (CICC), and the busbar is made up of six petal-like cables twisting in the clockwise direction around a centre copper core while petal-like cable is of the four-staged winding structure of compound lines formed by winding clockwise NbTi superconductor wires and copper wires. Its thermal stability performance is analyzed. Results show that the current sharing temperature is less 6K and hot temperature is less 250K under the maximum current with about 95.6kA, meeting design values.

Key words: CFETR feeder conductor, Thermal stability, Current sharing temperature
