Abstract: PROBLEM TO BE SOLVED: To provide a current limiter which has a high-temperature conductor simply and at a low price. SOLUTION: To manufacture a composite conductor 1 and 3, a silver foil 1 is put on a powder layer consisting of 2mm thick MgO on one side, and it is covered with a 600μm thick green sheet containing a high-temperature superconductor powder and an organic coupling agent on the other side. After fusion of the high-temperature superconductor, a 200μm thick glass or carbon fiber/epoxy resin layer is applied by vacuum impregnation to at least one side of the composite conductor 1 and 3 for its mechanical stabilization. To manufacture a resistant current limiter, a plate-shaped current limiting element having specified layer structure is cut in meander shape and besides two layers are bonded or pressed after interposition of cooling member as occasion demands. An inductive current limiter can be obtained by bending such a flexible plate, and besides, brazing a ring gap 9 with a metallic strip 5 consisting of silver.

Abstract: The present invention relates to a resistive superconducting current limiter with a meandering shape. This current limiter avoids current density peaks at the turning points (12) or corners of the conductor track (10, 11) in that the central path of the fault current when limiting occurs is artificially increased by appropriate design of the turning points. For this purpose, conductor material is removed in the region of the inner edge of the turning points (13), or the electrical bypass is reinforced at its outer edge (14).

Abstract: The arrangement has a superconductor (1) with weak points (A,B) distributed along the current flow direction (I) with reduced critical current density compared to the rest of the superconductor. At least one weak point has a reduced cross-section of a current-carrying cross-section of the superconductor. Independent claims are also included for the following: the use of a high temperature superconductor in a superconducting current limiter.

Abstract: A high temperature superconductor arrangement comprises a high temperature superconductor (1) and an electrical bypass (2). The current flows in the main current direction (3) through the arrangement. A contact layer (4) is provided between the superconductor and the bypass, the layer having a low anisotropic electrical conductivity. An Independent claim is also included for the production of the high temperature superconductor arrangement comprising applying the contact layer to the superconductor in a co-sintering or post-sintering process, and then applying the bypass. Preferred Features: The contact layer does not completely cover the superconductor.

Abstract: In a current limiter production process involving application of a high temperature superconductor (HTSC) starting material powder onto a silver layer (1) surface and then temperature and oxygen treatment to form the HTSC (3), the novelty is that (a), prior to applying the HTSC starting material powder, the opposite surface of the silver layer is placed on a powder layer which is chemically inert wrt. the hot HTSC; and (b) a mechanical stabilisation layer (4) is applied onto at least one main surface of the composite conductor (1, 3), after forming the HTSC (3). Also claimed is a current limiter having a composite conductor (1, 3) comprising a HTSC (3) in surface contact with a non-superconductive shunt resistor of a silver layer (1) parallel to the HTSC, the novelty being that (i) the HTSC (3) has a layer thickness (d3) of less than 500 (preferably less than 300) microns, the silver layer (1) has a layer thickness (d1) of less than 25 (preferably less than 10) microns and d1/d3 = less than 1/5, preferably less than 1/10; and (ii) at least one main face of the composite conductor (1, 3) is in surface contact with a mechanical stabilisation layer (4).
