摘　　要：文中所述机械型超导开关是一种新型超导开关,其主要用做超导储能磁体的持续电流开关(persistentcurrent switch,简称PCS)。文章简要介绍机械型超导开关的原理并计算PCS的损耗,然后详述机械型超导开关的设计,最后描述初步实验结果。When Superconducting Magnetic Energy Storage （SMES） moves in the energy -storage state, it needs a super- conducting switch to form circuit for holding the energy. The superconducting switch is also called persistent current switch （PCS）. Mechanical superconducting switch is a new kind of superconducting switch which is different from the thermally controlled and the magnetically controlled superconducting switch, it has high resistance when it is closed. In this paper, we compute the loss of PCS for first, then the basic properties of mechanical superconducting switch are discussed in detail. At last, we gives the result of experiment and conclusions.
