SELF-RECOVERING CURRENT-LIMITING FUSE

摘要

PROBLEM TO BE SOLVED: To surely secure a cut-off operation at the time of overcurrent in a self-recovering current-limiting fuse in which a current flowing state is secured by concatenating conductive particles in a liquid matrix by using dielectrophoretic force. SOLUTION: The liquid matrix of a non-magnetic material is housed in an insulated container of a non-magnetic material, and a pair of electrodes mutually opposing via this liquid matrix are arranged. The conductive particles are fluidized and dispersed in the liquid matrix. The insulated container is outside equipped with a magnetic field generating part to generate the magnetic field in a direction orthogonal to a fuse element formed by concatenation of solid particles between a pair of electrodes.
