Embodiment Construction

[0050] exist Figure 1a and 2a In , the tubular superconductor element is identified by 1, while the coil is identified by 2 (prior art) or 3 (according to the invention).

[0051] In addition, as is generally known, the ends of the superconductor element 1 have corresponding electrical contacts 4, whereby the superconductor element 1 can be electrically connected to a grid or to another current limiter element.

[0052] The electrical contacts 4 comprise materials that are common electrical conductors, typically metals such as copper, silver or alloys of these metals. Suitable materials for the electrical contacts 4 and their mounting methods are generally known and described frequently.

[0053] The coils 2 and 3 extend between the electrical contacts 4 substantially over the entire length of the superconductor element, however, the winding direction of the coil 3 according to the invention extends substantially at right angles to the winding direction of the coil 2 .

Abstract

The present invention relates to a superconductive current limiter component with magnetic field triggering having a tubular superconductor element (1) which is connected in electrical parallel with a trigger coil (3), wherein the trigger coil runs from a first end of the tubular superconductor element (1) on one side of the lateral face of the tubular superconductor element (1) in the direction of the second end of the tubular superconductor element (1), is deflected at that point to the other side of the lateral face and runs back in the direction of the first end, and so on.

Description

technical field [0001] The invention relates to a magnetic field triggered superconducting current limiter component, wherein the superconducting element is inserted into a coil and connected in parallel with the coil. Background technique [0002] Current limiters based on high-temperature superconductors (HTS) are of great benefit especially for safety systems of power supply systems, especially for high-voltage grids, since they are able to prevent unbalanced earth current spikes in the event of a short circuit, which would otherwise be Equipment damage will result. [0003] High-temperature superconductors provide new measures for optimizing power supply systems by reducing the load on devices in case of current spikes. [0004] In the superconducting state, superconductors behave like zero-loss electrical conductors. [0005] All superconducting materials suddenly lose their superconducting properties if: [0006] Exceeding a) the critical temperature (Tc); [0007]...
