| Abstract |
We investigated the current limiting and the recovery characteristics of a flux-lock type superconducting fault current limiter(SFCL) according to the winding directions. The flux-lock type SFCL consists of two coils. The primary coil was wound in parallel to the secondary coil through an iron core, and the secondary coil was connected with the superconducting element in series. We have changed the winding direction of coils to compare the resistive type SFCL with the flux-lock type SFCL. The current limiting and the recovery characteristics were dependent on the winding direction. The quenching time in the additive polarity winding was faster than that of the subtractive polarity winding or the resistivity type. A consumed energy in a superconducting element was represented as W=VIt=I²Rt. We found that there was a difference in the consumed energies in accordance with winding types because of differences in voltages imposed on a superconducting element in accordance with a winding direction. |
