摘要： Disclosed is a half-wave expulsion type superconducting fault-current limiter having an integral high speed switch module. The fault-current limiter has minimum superconducting elements and a circuit of which is formed in a hybrid type with an integral high speed switch module. The fault-current limiter supplies an electric power supplied from a power feeder to a system without loss thereof according to unique characteristics of the superconducting element when a normal current flows, and restricts an over current through a high speed switching contact point integrally inter-working with a driving coil and an arc changeover switch past a half period in a case that the over-current is generated by accidents such that electric power appliances, including circuit breakers in an electric power system, can be normally operated.
