Patent ID: 7995312

Claim:
An electric current limiter comprising: a cryogenic vessel having a main body and a cover, both defining an inner space separated from a surrounding space; superconducting elements of the HTSC type immersed in a cryogenic liquid contained in the inner space of the vessel; an ullage space between the cryogenic liquid and the cover; and bushings with conductors extending from the inner space of the vessel to the surrounding space, the conductors connecting the superconducting assemblies with a current path to be protected against a fault current, wherein the bushings are positioned in an area of the main body of the vessel surrounding the ullage space underneath the cover and wherein the cover is removable, and wherein said bushings are positioned in opposed wall parts of the main body of the cryogenic vessel, such wall parts of the main body designed as cylindrical extensions housing the bushings and that a flange is provided at the end of each extension for coupling ongoing electrical equipment.
