    Abstract: Overcurrent limiters (1) based on high temperature superconductors (SLa, SLb) have low availability because of inhomogeneities in high temperature superconductors, which lead to hot spots if stabilizing measures are not taken. In order to increase availability, in at least one current branch in parallel with a first high temperature superconductor (SLa), at least one inductive impedance (3) is provided. Advantageously, in at least one further current branch in parallel with this first high temperature superconductor (SLa), at least one further high temperature superconductor (SLb) is connected in series with a switch (Sb). In parallel with at least two sections of a high temperature superconductor (SLa, SLb), or in parallel with at least two high temperature superconductors connected in series, one varistor each and/or one inductive impedance each may be connected.

    Abstract: A heat pipe (1) carries off heat-loss in an inner conductor (21) and extends from the inner conductor as far as an outer conductor (22). It also has an insulating hollow body (5) to form an electric insulating section (7). The heat pipe can run in an insulator (24) to support the inner conductor. An independent claim is also included for a method for cooling a heavy-duty circuit breaker's inner conductor stretched as an oblong and surrounded by an outer conductor in the form of a casing.

    Abstract: Limitador de corriente superconductor resistivo con un circuito impreso aplicado sobre un soporte de un compuesto conductor que comprende un superconductor de alta temperatura y una derivación eléctrica, donde el circuito impreso comprende dos secciones rectilíneas de circuito impreso (10, 11) con la anchura de circuito impreso b y un elemento de esquina (15) dispuesto entre las dos secciones rectilíneas de circuito impreso (10, 11), las dos secciones rectilíneas de circuito impreso (10, 11) presentan un primer corte transversal conductor transversal Q1, el elemento de esquina (15) comprende una sección de anillo circular (12) con una capa superconductora (20) no modificada en cuanto al grosor con respecto a las secciones rectilíneas de circuito impreso (10, 11) con la anchura b, que une las dos secciones rectilíneas de circuito impreso (10, 11), caracterizado porque la sección de anillo circular (12) presenta localmente un segundo corte transversal conductor radial, que es diferente del primer corte transversal conductor Q1 con respecto a geometría y/o conductividad.

    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).
