摘　　要：从理论上证明三相系统用低温绝缘(CD)高温超导电缆在屏蔽层互联和特定敷设条件下可以达到屏蔽电流与导体电流量值相等、相位相反,实现屏蔽处无磁场的理想运行状态。可以用于CD绝缘超导电缆的结构和CD绝缘超导电缆线路电气参数的确定。This paper presents the theoretical evidence that preferable operation status of CD HTSC cable with no magnetic field outside its shield owing to the return current flowing through the shield equal and opposite to its phase current can be achieved by bonding two ends of shields of the CD HTSC cable installed in specific configuration of the cable system. The preferred structure of CD HTSC cable and its electrical parameter can thereby be determined.
