摘　　要：根据高温超导电缆测试用直流电源平台的要求,建立了硬件平台。该平台为模块化结构,具有输出精度高,便于扩展等特点;为方便操作,建立了基于LabVIEW的软件平台,对直流电源平台进行远程控制,并给出了远程控制的程序流程图,实现了电流的匀速上升和下降以及上升过程中的中断操作;利用该电源平台进行了超导电缆的临界电流测试实验,验证了直流电源平台符合高温超导电缆的测试要求。The hardware platform was established based on the requirements of DC power supply using in the test of HTS cable.The platform was of multiple-modules and expandable,and has high output accuracy.To control the supply conveniently,the software based on LabVIEW was constructed,which could provide remote controlling.Flow chart of the remote controlling program was given,which made the ascending and descending of the current possible.The experiment was done to measure the critical current of a HTS cable using the power system,and the result proved that the power supply meet the requirements for the test of HTS cable.
