摘要:

为把电流引线罐从EAST 大厅移到离装置约30m 外的电源大厅,重新设计和制造了连接新旧超导导体间的13 对超导接头。介绍了其中1 对超导接头的结构设计、空隙率的确定、理论直流电阻计算、压降计算和加工装配方案等。为此,制造了1 对超导接头,并进行通电测试,结果表明,所设计的超导接头结构和加工工艺满足EAST 工程的要求。

关键词: EAST, 超导接头, 压降计算, 接头电阻

Abstract:

Due to moving two current lead tanks to the new power hall which is 30 meters away from the EAST hall, 13 superconducting joints between the old and new superconducting conductor were designed and manufactured. This paper mainly introduces the structural design, air voids calculation, DC resistance theory calculation, calculation of pressure drop and process plan of one superconducting joint, etc. Therefore, a pair of superconducting joint was made and the electrical test was done. The results confirm that the design of superconducting joint structure and processing technology meet the needs of the engineering of EAST.

Key words: EAST, Superconducting joint, Pressure drop calculation, Joint resistance
