摘　　要：本文介绍10kV/1.5kA/3m单相冷绝缘高温超导电缆原型的主要结构和设计参数,以及对电缆原型进行的通流实验.实验研究电缆屏蔽层感应电流大小与导电层电流、屏蔽层连接电阻之间的关系.屏蔽层连接电阻的大小通过改变屏蔽层连接铜缆的根数来调节.实验结果验证了冷绝缘超导电缆的通流原理,并且表明当导体层电流大小相同时,屏蔽层连接电阻越小,屏蔽层感应电流越大.The structure, key technical parameters, and loading test results of a single-phase prototype of a 10kV/1.5kA cold dielectric superconductor cable system are presented in this paper. The relationship among in- duced current in the shield layer, current in the conducting layer, and connection resistance of the shield layer was studied by experiment. The resistance of the shield layer is changed by altering the number of the Cu cable connect- ing the shield layer. Test results verified the design concept of the cold dielectric superconductor cable, and indicated that for the same current magnitude in the conducting layer, current magnitude in the shield layer increases with de- creasing resistance of the shield layer.
