  • DC reactor with bobbin equipped with supplementary winding
    Publication number: 20050018368
    Abstract: A design of a bobbin for stacking a superconducting coil used in a DC reactor of a current limiting device for limiting fault current of an electric power system, is provided. The design of the bobbin overcomes difficulties of windings and problems including insulation between coils, difficulty in design of shape of bobbin, increase of joints, and degradation of stability caused during transposing of stacked windings of the superconducting coil. A superconducting coil is not quenched at a normal state, but the superconducting coil is quenched upon occurrence of fault current. When such is a case, current generally flows along the lowest resistance path, and the portion of the superconducting coil is overheated.
