Test and Analysis on the DC and AC I-V Characteristics of High Temperature Superconducting Cable
摘要
Abstract
The test methods for the DC and AC I-V characteristics are proposed respectively for a cold dielectric high temperature superconducting (HTS) cable that consists of YBCO coated conductor. A 0.2m, 110kV/1.5kA demo HTS cable is constructed using YBCO coated conductor, and an I-V characteristics test system is set up as well to obtain the DC, 30Hz, 50Hz and 100Hz AC I-V curves for the HTS cable. The experimental results show that the currents and voltages in the DC critical current characteristic curve behave E-J power exponential relationship, and the quench point of the HTS cable can be found clearly in this curve. But for the AC I-V characteristics curve, the voltages of the HTS cable is smooth when the current amplitude is less than the critical current of HTS cable. The voltage increases with the increase of the AC current in the HTS cable, and there is no inflection point in AC I-V characteristics curve of HTS cable. Those test results provide a reference for the operational stability of superconducting cable.关键词
