介绍了超导储能系统的失超保护实验,分别对实验装置、失超保护系统、实验连线以及实验电路四个方面进行了阐述.在超导储能系统运行过程中,通过测量在磁体电流超过临界电流情况下,失超保护系统中失超电压及电流的变化曲线,分析了不同充电电流对磁体阀值电压的影响以及在磁体参数改变下失超保护系统的适用情况.实验结果表明,失超保护系统能快速、准确地检测失超信号,并进行保护动作.同时,实验数据的统计也说明了不同的充电电流速度对阀值电压没有产生影响.

In this paper, the experiment about the quench protection of SMES System is presented. Respectively, the four aspects of the experiment are described which include the experimental device, the quench protection system, the experimental connection and circuit. During the running of SMES system, by measuring the curve about the quench voltage and current of the quench protection system in the condition of the current surpasses the magnet critical current, the correlation between the different charging current and the magnet threshold voltage is analyzed,as well the application of the quench protection system if the magnet parameters change . The results indicate that the quench protection system can quickly and accurately detect the quench signal and carry out the protection action. At the same time, the statistics data also shows that different speed of the charging current does not affect the threshold voltage.
