摘要

Inductive-resistive modular superconductive short-circuit current limiting device with double magnetic field transition. A short-circuit current limiting device (or fault) is described superconductive, modular, inductive-resistive, with double transition by magnetic field. Said limiter is characterized by having two stages, inductive and resistive and by using the inductive part, in addition, to produce the transition of the resistive part by magnetic field, which represents an important improvement because it avoids the traditional transition by current of this element that because it is produced inhomogeneously, it causes large local dissipations that degrade or burn the superconductor. The homogeneity in the transition facilitates the modular design of higher capacity limiters, since the adjustment of the transition of each module is less critical. The resistive part must be housed in the air gap of a normally ferromagnetic circuit, which can take different forms depending on the geometry of the resistive element.
