【発明の詳細な説明】
〔産業上の利用分野〕
本発明は核融合装置用超伝導コイル、大型加速器用超伝

超伝導システム用超伝導コイルに適用される超伝導導体
構造に関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention is directed to superconducting coils for nuclear fusion devices, superconducting coils for use in superconducting systems for supplying large currents to superconducting power storage devices such as superconducting films for large accelerators, etc. It relates to superconducting conductor structures applied to coils.
従来考えられている超伝導電力貯蔵装置用大電流超伝導
導体構造は、電流を安定に通電するために超伝導線材の
横に電気抵抗の小さい安定化材を大量に配置して安定化
を図っている。The conventional high-current superconducting conductor structure for superconducting power storage devices involves placing a large amount of stabilizing material with low electrical resistance next to the superconducting wire to stabilize the current flow. ing.

〔発明が解決しようとする課題〕
安定化材は何らかの外乱により、超伝導線が常伝導に転

ために、安定化材の断面積を大きくとるとともに比抵抗

。(Complete stabilization) [Problem to be solved by the invention] When the superconducting wire transitions to normal conductivity due to some disturbance, the stabilizing material bypasses the current flowing through the superconducting wire and stabilizes it. This is to allow it to flow through the material. At this time, in order to suppress Joule heat generation in the stabilizing material, pure CLI, pure A1, etc., which have a large cross-sectional area of the stabilizing material and have a small specific resistance, are generally used.
大電流用導体の場合、この安定化材の寸法は大きくとる
必要があるが、安定化材の寸法が大きくなると、安定化
胴中を流れるバイパス電流が一様になるのに時間を要し
、この−様になるまでの期間、局所的に電流密度の高い
部分が懲戒され全体としても一様に電流が流れた場合と
比べてジュール発熱量が大きくなるといった欠点がある
。In the case of a conductor for large currents, the size of this stabilizing material must be large, but when the size of the stabilizing material becomes large, it takes time for the bypass current flowing through the stabilizing shell to become uniform. During the period until this happens, there is a disadvantage that the portions where the current density is locally high are punished and the amount of Joule heat generated is larger than when the current flows uniformly throughout the entire device.
上記、技術水準ではバイパス電流が一様になるまでの期
間中に発生する高いジュール発熱量は安定性を低下させ

までの時間を短縮させうる超伝導導体構造を提供しよう
とするものである。According to the above-mentioned state of the art, the high joule heat generated during the period until the bypass current becomes uniform works in the direction of reducing stability. Therefore, the present invention shortens the time until the bypass current becomes uniform. The purpose of this study is to provide a superconducting conductor structure that is transparent.

分割してなることを特徴とする超伝導導体構造である。The present invention is a superconducting conductor structure characterized in that a stabilizing material disposed around a superconducting wire is finely divided in the direction of current flow using a material having lower electrical conductivity than the stabilizing material.

When using carbon, as a material with low electrical conductivity,
uNi alloy, S[IS material, when using pure helium as a stabilizing material, use^1 alloy, Cu as a material with low electrical conductivity.
When using a CuNi alloy as a Ni alloy, a SuS material, or a stabilizing material, a SUS material is used as a material with low electrical conductivity.

間が短縮され安定性が向上する。By making the superconducting conductor structure of the present invention as described above, when the superconducting wire transitions to normal conduction due to a disturbance, the bypass current flowing through the stabilizing material will flow through the divided stabilizing material. At this time, the time for the current to diffuse into the stabilizing material is shortened because the dimensions of the individual stabilizing materials are small, and the period during which Joule heat generation is high as in the prior art is shortened and stability is improved.

、製造コストの低減の効果がある。In addition, the material used to divide the stabilizer has higher strength than the material normally used for the stabilizer, and can be used to support the electromagnetic force applied to the superconducting wire, simplifying the structure and manufacturing. This has the effect of reducing costs.
本発明の一実施例を第１図によって説明する。 An embodiment of the present invention will be described with reference to FIG.

わち電気伝導度の低い、金属材料で構成した分割板３で
分割細分化している。The arrangement of the stabilizing material 2 around the superconducting wire l is the same as in the conventional example, but the stabilizing material 2 is a divided plate made of a metal material with high electrical resistance, that is, low electrical conductivity. It is subdivided into 3 parts.
このように分割することにより、超伝導が常伝導に転移
した場合に安定化材２への拡散電流４が流るとともに分
割板３の表面を高速で移動し、他の面からも安定化材２
中へ拡散電流５が侵入する。この拡散により、拡散時間
の短縮即ち安定性の向上を招く。By dividing in this way, when superconductivity transitions to normal conduction, a diffusion current 4 flows to the stabilizing material 2 and moves at high speed on the surface of the dividing plate 3, and the stabilizing material is also spread from other surfaces. 2
A diffusion current 5 enters inside. This diffusion shortens the diffusion time, ie improves stability.

割数が多い方がよいが、これは構成、加工性、工数等積
々の条件によって決められるものであって、要は安定化
材を分割細分化したことに本発明のポイントがある。Furthermore, it is better to divide the above-mentioned stabilizing material into many parts in order to suppress heat generation, but this is determined by various conditions such as composition, workability, man-hours, etc., and the key is to divide the stabilizing material into The key point of the present invention lies in dividing and subdividing.

上させる。さらに分割板を構造材料として使用すること
により、構造の簡略化、製造コスト低減の効果も期待で
きる。By subdividing the stabilizing material with dividing plates made of material with low electrical conductivity, the current diffusion time is shortened and stability is improved. Furthermore, by using the dividing plate as a structural material, the effect of simplifying the structure and reducing manufacturing costs can be expected.
