【摘要】 实验研究了超导螺线管磁体内部损耗分布以及导线位移和短路对磁体临界电流的影响.实验结果表明 (1)磁体内部线圈的损耗比外部线圈小.内部和外部线圈损耗的总和等于整个磁体的损耗. (2)导线位移和短路分别引起磁体磁滞迥线形状两种畸变,而且这两种畸变是不一样的. (3)导线位移和短路都可以降低磁体的临界电流. (4)磁体内部有短路时,可能成倍或几十倍地增加磁体的损耗.更多还原

【Abstract】 An experimental study on distribution of losses within a superconducting solenoid magnet and the effects of wire movement and shorts in the magnet on the critical current has been made. The experimental results obtained show that:(1)The losses of the inside coils in a magnet are smaller than those of the outside ones. The sum of losses of the inside and the outside coils is equal to that of the whole magnet.(2)The distortions of the shape of the hysteresis loop of a magnet are caused by either wire movement or shorts in the magnet. But the tw,o types of distortions are different from each other.(3)Both wire movement and shorts will possibly lead to a decrease of the critical current of the magnet.(4)The loss of a magnet due to the shorts within will possibly be twice, several times or even larger than that of the magnet without shorts.更多还原
