Definitions
- the invention relates to a high-temperature superconducting strip conductor composite comprising a substrate layer, a buffer layer lying thereon, an HTSC layer lying thereon, and a cover layer, and to be assigned to the field of superconductive current limiters in electrical power engineering.
- the substrate, the carrier tape, a superconducting tape conductor is used as a cold reservoir.
- the previous solutions for energy absorption reduce the electrical Banleiterwi- resistance, making it unattractive or unusable for use in the superconducting current limiter technology.
- the invention has for its object to reduce the temperature after a certain time in the current-carrying, normal conducting state in order not to damage the HTSC layer or to prevent the melting of strip conductors, in which a low-melting solder is used.
- the cooling layer is a metal layer to poor to non-conductive oxide layer of alkali, alkaline earth and rare earths and their compounds or ceramic materials.
- the cooling layer has a thickness of 20 microns to about 200 microns.
- the coating is an electrically poor or non-conductive cooling layer with good thermal conductivity and heat capacity.
- the cooling layers are thus metal oxides but also alloyed and unalloyed metals or ceramic materials.
- the poor or non-electrically conductive thin oxide layer is applied as a cooling layer.
- the oxide layer may be partially applied to the tape conductor or completely enclose the tape conductor.
- the additional layer does not affect the electrical properties of the stripline during normal operation of superconducting current transport. The job does not damage the tape conductor.
- the special effect is, on the one hand, that the temperature in the superconductor can be kept low during the limiting process, and, on the other hand, the recooling time after the limiting process is shortened by the layer itself. This is due to the good thermal conductivity and the small layer thickness, combined with the large and rough surface in contact with the coolant LN 2 .
- the layer fulfills the function of an electrical insulation layer and replaces insulation foils interposed therebetween with poor contact with the strip conductor.
- the strip conductor is represented by a piece in the single FIGURE 1.
- Figure 1 shows a section of the strip conductor, which is covered with the oxide layer as a cooling layer.
- the layer thickness ratios and the rest of the geometry are not drawn to scale. Only the layer sequence should be expressed in the detail sketch.
- the substrate is immediately covered by the buffer layer or layers, which may be an oxide layer or may be different oxide layers. This situation is followed by the superconductor, here for example YBCO. This superconductor layer follows the cap layer. Until then, the existing superconductor tape is present. This band is now covered with the oxide layer as a cooling layer. In order to give a dimension idea, the dimension specification for the substrate thickness is made here: it is up to 200 ⁇ m.
- Such superconductor tape is cooled by liquid nitrogen, LN 2 , or gaseous nitrogen, GN 2 , depending on the transition temperature.
- the different expansion coefficients of the cooling layer and the strip conductor are a a technical challenge.
- a metal such as aluminum
- This additionally applied metal is subsequently oxidized.
- the aluminum layer is stable and firmly bonded to the residual aluminum, which in turn has a solid metallic bond with the strip conductor.
- the so-structured band conductor increases the possible switching energy in current limiters, which consist of such superconducting band conductors - coated conductors or 2G wires in technical language.
- the high electrical resistance of the additional layer causes no increase in the limited short-circuit current.
