In the known example, the superconducting wire and the aluminum wire having the same linear shape are arranged, and the superconducting wire is arranged at the center, and the aluminum wire and the superconducting wire are alternately arranged around the periphery, so that a total of seven wires are arranged. In this case, the stability is improved by using aluminum, and the AC loss is reduced because the aluminum is divided and arranged. However, since the wire diameters are the same, the cross-sectional area ratio between the superconducting part and the aluminum part is always constant. Therefore, it is difficult to meet the required specifications, critical current density, stability, AC loss value, etc. of each superconducting device.

とにある。In the above-mentioned prior art, when aluminum is attached around the superconducting wire, it is technically difficult to make it thinner than a certain value because of the limit of the thickness of aluminum. Also in the case of the above-mentioned known example, the ratio of aluminum to the superconducting material is always constant. Therefore, when the amount of the stabilizer is not so large, there is a problem that the amount of aluminum is too large and the current density is lowered and the AC loss is increased. An object of the present invention is to provide a method for designing an aluminum-stabilized superconducting wire, which facilitates adjustment of the amount of stabilizing material, and can achieve improvement of current density, reduction of AC loss, improvement of stability and high strength.

することができる。That is, according to the present invention, the aluminum stabilizing material arranged around the central superconducting wire has a wire shape different from that of the central superconducting wire, and the aluminum wire is made of a material having high resistance and high strength such as CuNi. Then, a method of designing a superconducting wire in which a superconducting wire having the same diameter as the aluminum wire is mixed in a certain ratio and twisted around the central superconducting wire.
A specific example of the aluminum-stabilized superconducting wire of the present invention is shown in FIG. FIG. 1 is a cross-sectional structure diagram of the superconducting wire. In this example, four aluminum wires 8 and eight superconducting wires 9 are twisted around the central superconducting wire.
By changing the ratio of the aluminum wire 8 and the superconducting wire 9 arranged around the, it is possible to easily select the optimum amount of the stabilizing material, and increase the critical current density and high resistance.

の交流損失が大幅に低減される。From the above equation, in order to reduce the eddy current loss, it is necessary to reduce the diameter of the stabilizing material. According to the structure of the present invention, the aluminum stabilizer has a smaller diameter than that of the case of the aluminum external attachment shown in FIG. 2, so that the AC loss can be significantly reduced.
Since it is coated with a high strength material, reinforcement of low strength aluminum can be achieved. Next, in the conventional aluminum external wire, the amount of the stabilizer is adjusted by changing the thickness of aluminum, but it is difficult to make aluminum thinner than a certain value because of insufficient strength. In the case of not requiring so much, the amount of the stabilizer was over the specification value. In the configuration of the present invention, the amount of the aluminum stabilizer can be adjusted by changing the ratio of the aluminum wire 8 and the superconductor wire 9 twisted around the central superconducting wire. is there. This is the central superconducting wire 7, the surrounding aluminum wire 8 and the superconducting wire 9.
This is achieved by having different wire diameters. In addition, the central superconducting wire 7, the aluminum wire 8 and the superconducting wire 9 are made of CuN.
Since coating is performed with a material having high resistance and high strength such as i, a large loop of eddy current is cut off, and AC loss mainly due to eddy current loss is significantly reduced.

However, when the number of aluminum is 0, the resistance of aluminum is 1/10 of that of copper. Therefore, the equivalent amount (S) of the stabilizing material was calculated by the following equation. For comparison, the case where copper, which has been conventionally used, is used as the stabilizing material instead of aluminum is also shown.

きる。Generally, the larger the amount of the stabilizer, the better the stability, and the higher the critical current density per conductor cross-sectional area, the more compact the coil may be. Conversely, the smaller the AC loss, the better. 8 to 10, the stability is excellent when the amount of aluminum is large, but the critical current density decreases and the AC loss increases. On the other hand, when the amount of aluminum is small, the stability decreases, but the current density increases and the AC loss decreases. Therefore, it is common to determine the configuration according to the specifications and uses. If the amount of the stabilizing material, the critical current density, and the AC loss amount are specified, the configuration can be easily determined.

数はこれに限らす８〜１６程度にとることができる。On the other hand, in the conventional aluminum external wire, the amount of stabilizing material is adjusted by changing the thickness of aluminum. Since there is a limit to thinning the thickness of aluminum, if the stabilizer is not required so much, the structure will have too much aluminum, resulting in a decrease in current density and an increase in AC loss. According to the invention,
By arbitrarily changing the diameters of the central superconducting wire and the surrounding wires, it is possible to flexibly adapt and achieve high current density and low AC loss. In the region where the amount of the aluminum stabilizing material is small, the present invention improves the current density by about 10% as compared with the conventional case. Regarding AC loss, when comparing superconducting wires with the same current capacity, conventional aluminum external type and high resistance CuNi
Compared with superconducting wires that are not coated with and superconducting wires in which stabilizing material wires are twisted, the AC loss values that they have are one to two orders of magnitude lower. The case where the total number of the aluminum stabilizing wires and the superconducting wires twisted around the central superconducting wire is 12 has been described above, but the total number can be about 8 to 16 which is not limited to this.

る。According to the present invention, since it is possible to construct a structure in which a stabilizing material, which is difficult to realize with an aluminum external superconducting wire, is rarely required, there is an effect of increasing the current density.
In addition, since aluminum is coated with a material with high resistance and high strength such as CuNi, the AC loss can be reduced by one to two orders of magnitude compared to the conventional superconducting wire in which the stabilizing wire and superconducting wire are simply twisted together. It also has the effect of increasing strength.
