摘要： PROBLEM TO BE SOLVED: To supply uniform AC current to all superconducting wires and increase AC critical current by electrically taking out a plurality of superconductor layers concentrically stacked through an insulating material in the mutually insulated state, and connecting them to an impedance adjusting device. SOLUTION: Taking out conductors 21-23 of a terminating connection device 20 are coaxially constituted through an insulating material between conductors. The taking out conductors 21-23 are taken out to the atmosphere through a bushing 24, and constitute terminal part 21a-23a in the atmosphere. The terminal parts 21a-23a are connected to impedance adjusting devices 41-43 with lead wires or bus bars respectively, the adjusting devices 41-43 are electrically bundled and connected to an AC supply system 44. The adjusting devices 41-43 are adjusted so that the sum of impedance of the adjusting devices 41-43 is equal to that of impedance of the superconductor layers 11-13 to make current flowing through the superconductor layers 11-13 uniform.

摘要： PROBLEM TO BE SOLVED: To protect a shield layer sufficiently, and to prevent an excessive current form flowing through the shield layer in case of short circuit accident. SOLUTION: Mulutiple oxide superconductive line materials or the like are spirally wound on the outer peripheral surface of a winding core 1 to form a superconductive conductor layer 2. A tape made of craft paper or semi- synthetic paper is wound as multiple layers on the superconductive conductor layer 2 to form an insulating layer 3. Multiple superconductive wires are spirally wound on the outer peripheral surface of the insulating layer 3 to provide a shield layer 4, thereby forming a core part of a superconductive cable. A protective tape layer 5 is formed on the shield layer 4. Then, a metal tape protective layer 6 using a copper tape, a copper wire or a copper braiding is formed to protect the shield layer 4 and to distribute short circuit current in a short circuit accident.

摘要： PROBLEM TO BE SOLVED: To improve the operating rate of installed devices in a container by providing a means, which heats the intended part on the upper side than the liquid surface to be measured in addition to a heating means for heating the upper end part of a liquid-surface detecting element comprising a superconductor wire. SOLUTION: A liquid-surface inspecting element 1 comprises a superconductor wire, which is arranged in the up and down directions. One end of a heater wire 2 is connected to the upper end of the liquid-surface detecting element 1, and the other end is connected to a current source 7 through a lead wire 3b. The lower end of the liquid-surface detecting element 1 is connected to the current source 7 and a voltmeter 8 through lead wires 3a and 4a, and the upper end is connected to the voltmeter 8 with a lead wire 4b. Among heaters 11a-11c, the heater 11a is provided in the vicinity of the upper side of the highest position of the liquid surface, and the heater 11c is provided in the vicinity of the upper side of the lowest position of the liquid surface. When the liquid surface starts to be lowered from the initial highest position and stops the change, the heating of the heater 11a and the lowering of the liquid surface are confirmed. The same motion is performed for the heaters 11b and 11c. Even, if the part upper than the liquid surface is frozen, the liquid surface level can be measured without heating the entire container.

摘要： PROBLEM TO BE SOLVED: To provide a superconducting cable for alternating current which reduces an AC loss through uniformization of currents conductor layer and shield layer by adjustment of the winding pitch of each of the layers, and reduces an AC due to the longitudinal magnetic field by reducing the generation of the vertical magnetic field. SOLUTION: When the number of conductor layers is an integer N, the conductor layers are wound in the same direction from layer one to layer N/2 counted from the inside when the number of the layers is an even number, while from layer one to layer (N-1)/2 counted from the inside when the number of the layers is an odd number with the length of the pitch increasing gradually. Next, the conductive layers are wound in the direction opposite to the inside layers from layer N/2+1 to layer N when the number of the layers is an even number, while from layer (N+1)/2 to layer N when the number of the layers is an odd number with the length of the pitch decreasing gradually. The cable comprises the conductor layers, and the shield layers formed of the layers according to similar relations to the conductor layers, when the number of the shield layers is assumed to be an integer n.

SOLUTION: In a superconducting cable having plural shield layers 5, 6, and 7 insulated each other, the connection portion position of each shield layer on both sides is replaced with each other (inside position is replaced with outside position, middle position with inside position and outside position with middle position) and connected at the required connection portions so as to have the substantially same cable length in which each shield layer after connecting a set of cables of wire paths is from the inner layer and the outer layer. The connection portion of the superconducting cable has the following configuration. A cable conductor 1 is connected at a connection portion 2, an insulator 3 is connected at a reinforce insulator 4, after which the cable shield layers on both sides are wound back and stage-cut, the connection portion position of each shield layer on both sides is replaced with each other and connected, and a heat insulation sleeve 9 is covered and connected to a cable heat insulation tube 10.

摘要： PROBLEM TO BE SOLVED: To improve the efficiency of a quench monitor by fixing leads for voltage measurement to at least two superconductors out of three or more superconductors connected in parallel, and measuring voltages which are simultaneously generated in the two superconductors. SOLUTION: Lead wires 30 are connected, via current taps 20, with superconductors 10, 11 out of superconductors 10, 11, 12, 13 connected in parallel. The lead wires 30 are connected with voltage measuring apparatuses 40, 41. The voltages generated in the superconductors 10, 11 are monitored by comparing the voltages with a previously set regulation value. The regulation value is set by considering precision of the measuring apparatuses, noise, perturbation of an external electromagnetic field, etc. When the measured voltages of the superconductors 10, 11 are higher than or equal to the regulation values, it is judged that a circuit is quenched or in its preceding stage. When only the one out of the superconductors 10, 11 generates a voltage higher than or equal to the regulation value, it is not judged that the circuit is quenched.
