PURPOSE:To provide a superconducting current limiter in which a superconductor is not quenched in an ordinary power transmission operation, in which a superconducting state can be maintained and in which the superconductor can be returned to the super-conducting state in a short time after it has been quenched in an abnormality. CONSTITUTION:A superconducting current limiter S is provided with a superconductor 3 which is formed on the outer circumferential face of a cylindrical support 11 and with a coil 5 which is wound on the outer circumference of the superconductor 3 and which is connected to a power line. Uneven parts 4 are formed on the outer circumferential face of the superconductor 3. Then, the critical current value of the superconducting current limiter S can be increased by the uneven parts 4 on the superconductor 3, the cooling time of the superconductor 3 is shortened, and the return time to a superconducting state can be shortened. In addition, the density of the uneven parts 4 is made denser the closer they approach end parts of the superconductor 3, and the height of the uneven parts 4 is formed to be higher the closer they approach the end parts of the superconductor 3. |
