Claims13
Fault current limiter comprising:
- at least one current limiting unit, wherein the current limiting unit is arranged within the interior of an insulation housing and wherein the current limiting unit including one or more superconducting elements, where the current limiting unit forms a casing which spatially separate the superconducting elements from the surrounding interior of the insulation housing and where the fault current limiter unit includes a first cooling medium circuit for cooling the superconducting elements within the current limiting unit and a second cooling medium circuit for supplying the surrounding interior of the insulation housing, wherein the one or more superconducting elements are electrically connected to current supply tubes which serve to feed and discharge cooling medium to the fault current limiting unit.
Current limiting unit comprising:
- one or more superconducting elements and current supplies for electrically connecting the superconducting elements to further current limiting units and/or to an external grit, wherein the current limiting unit forms a casing which spatially separates the superconducting elements from the surrounding wherein the one or more superconducting elements are electrically connected to current supply tubes which serve to feed and discharge cooling medium to the fault current limiting unit.
