摘要： A method for producing an aluminum-stabilized superconducting wire is dislcosed herein, which comprises alternately winding superconducting elementary wires and high purity wires around a core, such as an electrically insulated copper wire core, impregnating the entire wire arrangement with solder to bind the wires together and subsequently forming or drawing the wire arrangement to increase the adhesion between the wires. In another embodiment, the thus-impregnated wire arrangement is subjected to a heat treatment to recover the residual resistance ratio of the aluminum. The impregnated wire arrangement is characterized by having a high mechanical toughness and improved electrical contact for greater electrical stability.

摘要： The invention relates an Al-stabilized superconducting wire for use in a superconducting magnet used in a charging magnetic field, such as a pulse magnet and the like, and particularly to an Al-stabilized superconducting wire having the properties of reduced size and light weight, high current density, high stability, low AC loss, etc., and a method for producing the same. The said Al-stabilized superconducting wire has a core chosen from a superconducting elementary wire, an electrically insulated Cu or a Cu alloy, or a nonmagnetic metal or alloys thereof, and wherein the superconducting elementary wires and high purity Al wires are alternately stranded around said core. The stranded cable is bonded by impregnating it with solder, or further by subjecting it to a reduction process and heat treatment thereby making it possible to obtain an aluminum stabilized superconducting wire having said high properties.

摘要： A current limiting device using a superconductor limits a current flowing throu A c5 V pV:a current limiting coil, which mangetically couples to the superconductor. A control coil is provided to magnetically couple with the current limiting coil when the superconductor is switched to a normal conduction state. A variable control impedance is connected to the control coil to adjust a control current flowing through the control coil. The current limiting impedance value of the current limiting coil is adjusted by the value of the control impedance to obtain an adjustable value of the current flowing through the current limiting coil.

摘要： A superconducting wire comprises a wire element wherein a plurality of superconducting filaments are arranged in a metallic matrix, and a covering layer which is formed on the surface of the wire element with a number of filaments and has a laminated structure including at least one insulator film as the lower layer and at least one thermal conductor film as the upper layer. Frictional heat generated on the surface of the superconducting wire is prevented from being conducted to superconducting filaments by virtue of the presence of the insulator film, and is conducted through the thermal conductor film to be dissipated. Therefore, the temperature of the superconducting filaments is hardly raised.
