摘要
Dy-Ba-Cu-O是电流引线的理想材料,因为它具有低导热性和高临界电流密度,在高磁场下可达77 K。本研究研究了低温冷却条件下Dy-Ba-Cu-O大电流引线的载流性能。电流引线由Dy-Ba-Cu-O块超导体40 mm x 3 mm x 0.8 mm、铜电极和保护玻璃纤维增强塑料片组成。当温度为77 K时,电流引线可输送400 A以上的大电流,并且随着冷却温度的降低,电流引线的载流能力增加。
Dy-Ba-Cu-O is an ideal material for current leads because it has a low thermal conductivity and a high critical current density of 77 K in high magnetic fields. In this study, current carrying properties of Dy-Ba-Cu-O bulk current leads under the cryocooler-cooled condition have been investigated. The current leads consisted of a Dy-Ba-Cu-O bulk superconductor 40 mm x 3 mm x 0.8 mm, copper electrodes and a protective glass-fiber-reinforced-plastic sheet. Large currents of more than 400 A could be transported through the current leads at 77 K and the current-carrying capacity of the current leads increased with decreasing cooling temperature.
