CURRENT LIMITER

摘要

A current limiter comprising two permanent magnets bonded between a pair of opposing cores while spaced apart from each other to form a closed magnetic circuit, and coils wound around the cores to circulate saturation magnetic flux being generated from the permanent magnets, wherein a nonmagnetic spacer is provided between the two permanent magnets closely thereto so that the nonmagnetic spacer bears an electromagnetic attraction acting between the permanent magnets to lock the permanent magnets.
