| Abstract: | The distribution of fault currents is studied when the 110kV cold dielectric high temperature superconducting(HTS) cable is in quench state.On this basis,the calculating model of the temperature relationship with time under different fault currents was established.The calculating results were gotten through MATLAB and the results were analyzed.In order to make further research of the effect of fault currents on the temperature of the HTS cable,the time consumed was calculated when the cable temperature rose up to a certain value under different fault currents. |
| Keywords: | CD HTS cable Quench Fault currents Temperature calculation |
