摘　　要：首先对Pt1000温度计在20K到室温范围的温度进行校准,进而应用在ITER高温超导电流引线超导模件分流器安全性能实验研究中,实现低温到室温的测量和控制。实验和测量结果表明:Pt1000温度计在20K^70K的误差一般小于1K,完全可以代替Cernox温度计用于ITER高温超导电流引线超导模件分流器的安全性研究中,能够大大降低其实验测试费用。Calibration was firstly studied in detail on ptl000 thermometer from 20K to room temperature, and then ptl000 thermometer application study was discussed to achieve the low - temperature measurement and control of temperature in safety experiment for ITER superconducting moldings shunt of high - temperature superconductive current lead. Experiments and meas- urements show that Ptl000 thermometer of error generally less than 1K in 20 -70K, instead of Cernox thermometer, can be used to LOFA experiment of HTS current leads to reduce the cost of the experimental test.
