| Abstract: | A 1.5m 220kV/3kA cold-dielectric high-temperature superconducting model cable was designed and fabricated in order to investigate the transient characteristic when it was put into power grid.Furthermore,fault-current experiment was successfully performed with a current of 40.4kArms and duration of 2s.The design of copper-former and homogenous current design of superconducting cable was particularly described.Short-circuit with a current of 40.4kArms and duration of 2s was applied to the model cable.The experiment indicates the cable could stand for the 220kV short-circuit demands and validate the correctness and rationality of the cable design. |
