    • Electric fault current limiter has superconducting elements inside a cryogenic vessel and bushings for connecting an external circuit. The electric fault current limiter (1) includes a cryogenic vessel (2) and superconducting assemblies (5) including high temperature type superconducting elements (HTSC) immersed in a liquid coolant (6) such as liquefied nitrogen. Bushings (25, 28) with conductors (17, 18) are associated with a main body (3) of the vessel (2) such that the conductors (17, 18) extend horizontally from a surrounding space into an ullage space (8) situated between a level (7) of the liquid coolant (6) inside the vessel (2) and a cover (4). The arrangement of the bushings (25, 28) according to the invention allows for removing the cover (4) without dismantling electrical connections between the current limiter (1) and a circuit to be protected as is necessary with prior art limiters.
    • 电气故障限流器在低温容器内部具有超导元件和用于连接外部电路的衬套。 电气故障限流器(1)包括低温容器(2)和超导组件(5),其包括浸入液化冷却剂(6)如液氮中的高温型超导元件(HTSC)。 具有导体(17,18)的衬套(25,28)与容器(2)的主体(3)相关联,使得导体(17,18)从周围的空间水平延伸到空的空间(8) 位于容器(2)内的液体冷却剂(6)的水平面(7)和盖(4)之间。 根据本发明的衬套(25,28)的布置允许移除盖(4)而不拆卸电流限制器(1)和要被保护的电路之间的电连接,如现有技术的限制器所必需的。
