Resistive short-circuit current limiter e.g. for AC supply mains

摘要

A resistive short-circuit current limiting device includes a carrier or supporting body made of an electric insulating material, and at least one conductor path structure of high temperature coefft. (Tc) superconducting material is arranged on the carrier body. Mainly linearly extending conductor path sections and non-linear conductor path sections are contained in the conductor path structure, which also includes end pieces for making contact with the adjoining conductors. The non-linear conductor path sections (11a,16b) are arcuate in shape and of a maximum radius: v = ra/rc of 7, where ra is the outer radius and rc the inner radius of the respective arcuate conductor path section.
