摘　　要：文中介绍了以采集卡为测量手段,由交流电流源、测量系统、电流源保护系统和补偿系统组成的高温超导带材/磁体交流损耗测试系统。测试系统将功率补偿技术、电感补偿技术应用于采集卡交流损耗测试方法中。通过单匝带材交流损耗测试、线圈交流损耗测试等测试结果,验证了高温超导带材/磁体交流损耗测试系统测试的准确性和稳定性。In this paper, a new measuring system for the AC loss of High Temperature Superconducting (HTS) tapes and coils was designed, and tested. The system consists of AC current source, acquisition system, power protection system, compensation system, and the measurement is based on the high sensitivity data acquisition card. The power compensation technology and inductance com-pensation technology were applied in this system. The tests on the AC loss of types and coils prove the testing stability and accuracy of the new AC loss measuring system for HTS tapes and coils.
