摘　　要：简述了300kW超导单极电机低温试验用的氦液化系统，指出了在液化系统设计和安装中应着重考虑的有关问题；介绍了300kW超导单极电机的超导磁体低温系统及低温试验，详细介绍了磁体预冷、液氮液氦输往过程和磁体的降温情况，提出了提高液氦输送效率应采取的有关措施。　The helium liquefying system used for the cryogenic experimental research on the 300kW　superconducting homopolar machine has been briefly introduced, and some problems must be　taken into account in designing and installation of the system have been presented. The super　conducting magnet system of the 300kW superconducting hoinopolar machine and it's cooling　down and transfer with liqiud helium, and the cryogenic experimental results of the magnet　have been emphatically provided. And the methods for raising the liquid helium transfer coefficient 　have been given
