Description

本発明は補強高温超電導線、およびそれを巻線した高温超電導コイルに関する。   The present invention relates to a reinforced high-temperature superconducting wire and a high-temperature superconducting coil wound with the same.

ハステロイなどのテープ状の金属基板上に酸化セリウムなどの中間層を形成し、その上に厚さ数μｍ程度のイットリウム系などの酸化物超電導層が形成された第２世代線材とよばれる高温超電導線が開発されてきている。この高温超電導線は、酸化物超電導層や中間層などで剥離する可能性があり、剥離した場合には超電導特性が劣化してしまうおそれがあった。   High-temperature superconductivity called second-generation wire, in which an intermediate layer of cerium oxide or the like is formed on a tape-like metal substrate such as Hastelloy, and an yttrium-based oxide superconducting layer with a thickness of several μm is formed on the intermediate layer. Lines have been developed. The high-temperature superconducting wire may be peeled off at the oxide superconducting layer, the intermediate layer, or the like, and when it is peeled off, the superconducting characteristics may be deteriorated.

したがって、形状保持や真空中での伝熱を目的として、エポキシ樹脂などで、高温超電導線を巻線したコイルを含浸した場合には、樹脂の硬化収縮や冷却時の熱応力で剥離してしまうおそれがあることが懸念される。   Therefore, when impregnating a coil wound with a high-temperature superconducting wire with epoxy resin or the like for the purpose of shape retention or heat transfer in vacuum, it will be peeled off due to the heat shrinkage of the resin or the thermal stress during cooling. There is concern that there is a fear.

この対策として、高温超電導線を補強することが考えられるが、補強構造としては、特許文献１に示されるように、金属テープ線を用いて高温超電導線を密封する方法が開示されている。   As a countermeasure, it is conceivable to reinforce the high-temperature superconducting wire. As a reinforcing structure, as disclosed in Patent Document 1, a method of sealing the high-temperature superconducting wire using a metal tape wire is disclosed.

しかしながら、図９に示すように特許文献１で開示された高温超電導線２を補強テープ線３で密封した構成では、補強テープ線３と高温超電導線２の間の空間２０が断熱層になり、補強した高温超電導線２を、巻回して樹脂含浸して高温超電導コイル（図示せず）を製作した場合に、伝熱により高温超電導線２を冷却することが困難になってしまうという課題があった。一方、補強テープ線３と高温超電導線２の間を半田などで一体化してしまうと、高温超電導線２が厚くなることで曲がりにくくなり、巻線作業が難くなると同時に、曲げ変形により高温超電導線２に応力が発生し、高温超電導線２が劣化し易くなってしまうという課題があった。   However, in the configuration in which the high temperature superconducting wire 2 disclosed in Patent Document 1 is sealed with the reinforcing tape wire 3 as shown in FIG. 9, the space 20 between the reinforcing tape wire 3 and the high temperature superconducting wire 2 becomes a heat insulating layer, When the reinforced high-temperature superconducting wire 2 is wound and impregnated with a resin to produce a high-temperature superconducting coil (not shown), it is difficult to cool the high-temperature superconducting wire 2 due to heat transfer. It was. On the other hand, if the reinforcing tape wire 3 and the high-temperature superconducting wire 2 are integrated with solder or the like, the high-temperature superconducting wire 2 becomes thick and difficult to bend, and winding work becomes difficult. There is a problem that stress is generated in 2 and the high-temperature superconducting wire 2 is likely to deteriorate.

本発明は、上述した課題を解決するためになされたものであり、酸化物超電導層を剥離させる力に弱い高温超電導線を補強テープ線などで補強したとしても、真空中での伝熱による冷却が可能であるとともに、巻線作業がし易く、超電導特性が劣化しない補強高温超電導線、およびそれを巻線した高温超電導コイルを提供することを目的とする。   The present invention has been made in order to solve the above-described problems. Even if a high-temperature superconducting wire that is weak against the force to peel off the oxide superconducting layer is reinforced with a reinforcing tape wire or the like, cooling by heat transfer in vacuum is performed. An object of the present invention is to provide a reinforced high-temperature superconducting wire that is easy to perform winding work and does not deteriorate superconducting characteristics, and a high-temperature superconducting coil wound with the same.

本発明は、金属基板上に中間層および酸化物超電導層を形成してなるテープ形状の高温超電導線と補強テープ線から構成される補強高温超電導線において、補強テープ線は、高温超電導線を覆うように幅方向の両端が折り曲げられ、折り曲げられた幅方向の両端は、高温超電導線の金属基板側の面または高温超電導線の金属基板側の面と平行な面と対向し、高温超電導線の金属基板側の面及び高温超電導線の金属基板側の面と平行な面に固着されず、かつ幅方向の両端同士は接触せずに配置されていることを特徴とする補強高温超電導線。 The present invention relates to a reinforced high-temperature superconducting wire composed of a tape-shaped high-temperature superconducting wire formed by forming an intermediate layer and an oxide superconducting layer on a metal substrate and a reinforcing tape wire. The reinforcing tape wire covers the high-temperature superconducting wire. Thus, both ends in the width direction are bent, and both ends of the folded width direction are opposed to the surface of the high-temperature superconducting wire on the metal substrate side or the surface parallel to the surface of the high-temperature superconducting wire on the metal substrate side. A reinforced high-temperature superconducting wire, characterized in that the reinforced high-temperature superconducting wire is not fixed to a surface on the metal substrate side and a surface parallel to the surface on the metal substrate side of the high-temperature superconducting wire , and is disposed without contacting both ends in the width direction.

また本発明に係る高温超電導コイルは、上記補強超電導線が巻回され、この補強超電導線の周囲またはこの補強超電導線間には絶縁材が配置され樹脂含浸されていることを特徴とする。   The high-temperature superconducting coil according to the present invention is characterized in that the reinforcing superconducting wire is wound, and an insulating material is disposed around the reinforcing superconducting wire or between the reinforcing superconducting wires and impregnated with resin.

本発明によれば、酸化物超電導層を剥離させる力に弱い高温超電導線を補強テープ線などで補強した場合においても、真空中での伝熱による冷却が可能であるとともに、巻線作業がし易く、超電導特性が劣化しない補強高温超電導線、およびそれを巻線した高温超電導コイルを得ることができる。   According to the present invention, even when a high-temperature superconducting wire that is weak to the force of peeling off the oxide superconducting layer is reinforced with a reinforcing tape wire or the like, it can be cooled by heat transfer in vacuum and the winding work can be performed. It is easy to obtain a reinforced high-temperature superconducting wire that does not deteriorate the superconducting characteristics, and a high-temperature superconducting coil wound with the same.

以下、本発明に係る補強高温超電導線、およびそれを巻線した高温超電導コイルの実施の形態について、図面を参照して説明する。   Embodiments of a reinforced high-temperature superconducting wire according to the present invention and a high-temperature superconducting coil wound with the same will be described below with reference to the drawings.

第１実施形態を、以下図１から図６を参照して説明する。   A first embodiment will be described below with reference to FIGS.

FIG. 1 shows Example 1 according to the first embodiment of the reinforced high-temperature superconducting wire of the present invention, where (a) is a longitudinal sectional view taken along a plane perpendicular to the longitudinal axis direction, and (b) is (a). It is sectional drawing which expands and shows the high temperature superconducting wire shown by. In FIG. 1A, the reinforced high temperature superconducting wire 1 is composed of a high temperature superconducting wire 2 and a reinforcing tape wire 3. The reinforcing tape wire 3 is bent at the end in the width direction orthogonal to the longitudinal axis direction and is disposed so as to cover the high-temperature superconducting wire 2.

高温超電導線２は 図１（b）に示すように、テープ形状の金属基板４の表面に、中間層５、酸化物超電導層６、および保護層７、安定化層８を順次形成した積層構造を有している。なお、図１では、保護層７および安定化層８を設けた構成を示したが、本発明で用いられる高温超電導線２は、保護層７および安定化層８のいずれかが形成されない構成とすることができる。また、高温超電導線２は、全体をホルマール（登録商標）やカプトン（登録商標）で被覆して絶縁処理された構成としても良い。   As shown in FIG. 1B, the high-temperature superconducting wire 2 is a laminated structure in which an intermediate layer 5, an oxide superconducting layer 6, a protective layer 7, and a stabilizing layer 8 are sequentially formed on the surface of a tape-shaped metal substrate 4. have. Although FIG. 1 shows a configuration in which the protective layer 7 and the stabilizing layer 8 are provided, the high-temperature superconducting wire 2 used in the present invention has a configuration in which either the protective layer 7 or the stabilizing layer 8 is not formed. can do. Further, the high-temperature superconducting wire 2 may be configured to be entirely insulated with formal (registered trademark) or Kapton (registered trademark).

補強テープ線３としては、例えば銅やステンレスなどからなる金属テープが用いられる。金属基板４としては、例えばハステロイ（登録商標）などのニッケル合金、ステンレスなどからなるテープが用いられる。   As the reinforcing tape wire 3, for example, a metal tape made of copper or stainless steel is used. As the metal substrate 4, for example, a tape made of nickel alloy such as Hastelloy (registered trademark), stainless steel or the like is used.

中間層５としては、例えば酸化セリウム、酸化マグネシウムなどからなる複数の層から構成されている。この構成によって金属基板４から酸化物超電導層６への金属の拡散を防止することができ、さらに中間層５の格子定数を金属基板４よりも酸化物超電導層６に近いものとすることができ、それにより金属基板４と酸化物超電導層６との結晶のミスマッチによる格子歪みを緩和することができる。   The intermediate layer 5 is composed of a plurality of layers made of, for example, cerium oxide or magnesium oxide. With this configuration, metal diffusion from the metal substrate 4 to the oxide superconducting layer 6 can be prevented, and the lattice constant of the intermediate layer 5 can be closer to the oxide superconducting layer 6 than to the metal substrate 4. Thereby, lattice distortion due to crystal mismatch between the metal substrate 4 and the oxide superconducting layer 6 can be relaxed.

酸化物超電導層６としては、例えばイットリウムなどの希土類（Ｒｅ）が含まれるＲｅ１２３系などの高温超電導材料が用いられ、Ｒｅは、Ｌａ、Ｎｄ、Ｓｍ、Ｅｕ、Ｇｄ、Ｄｙ、Ｈｏ、Ｅｒ、Ｔｍ、Ｙｂ、Ｌｕ及びＹから選択される１種又は２種以上の元素である。   As the oxide superconducting layer 6, for example, a high-temperature superconducting material such as Re123 containing rare earth (Re) such as yttrium is used, and Re is La, Nd, Sm, Eu, Gd, Dy, Ho, Er, Tm. , Yb, Lu and Y are one or more elements.

保護層７としては、例えば銀、金など用いられる。安定化層８としては、例えば銅からなる層が用いられる。安定化層８は、金属テープを半田付けしても良い。また、安定化層８として片面のみに付加する構成を示したが、全面を被覆する構成も可能である。   As the protective layer 7, for example, silver or gold is used. For example, a layer made of copper is used as the stabilization layer 8. The stabilization layer 8 may be soldered with a metal tape. Moreover, although the structure added only to one side was shown as the stabilization layer 8, the structure which coat | covers the whole surface is also possible.

本構成によれば、補強高温超電導線１を巻回して高温超電導コイルを製作し、冷却や電磁力印加をした場合に、図１（b）に示すように高温超電導線２の積層構造の層間を剥離させる力Ｆが働いたとしても、端部が折り曲げられた補強テープ線３により補強されているので、層間の剥離が抑制される。   According to this configuration, when a reinforced high-temperature superconducting wire 1 is wound to produce a high-temperature superconducting coil and cooling or electromagnetic force is applied, the interlayer of the laminated structure of the high-temperature superconducting wire 2 as shown in FIG. Even if the force F that peels off is applied, since the end portion is reinforced by the bent reinforcing tape wire 3, peeling between layers is suppressed.

また、巻線時には、高温超電導線２と補強テープ線３は一体化されていないため、巻線時に補強高温超電導線１の内部に発生する応力が緩和されるため、巻線作業がし易く、かつ巻回した後に樹脂含浸した場合に、高温超電導線２と補強テープ線３の間にも樹脂が含浸されるため、真空中においても伝導により高温超電導線２を冷却することが可能となる。   Moreover, since the high-temperature superconducting wire 2 and the reinforcing tape wire 3 are not integrated at the time of winding, stress generated inside the reinforced high-temperature superconducting wire 1 at the time of winding is relieved, so that the winding work is easy. When the resin is impregnated after winding, the resin is also impregnated between the high-temperature superconducting wire 2 and the reinforcing tape wire 3, so that the high-temperature superconducting wire 2 can be cooled by conduction even in a vacuum.

なお、図２の実施例１の変形例に示すように、補強高温超電導線１には複数の高温超電導線２が含まれていてもよい。   In addition, as shown in the modification of Example 1 of FIG. 2, the reinforced high temperature superconducting wire 1 may include a plurality of high temperature superconducting wires 2.

本実施例によれば、高温超電導線２の層間を剥離させる力Ｆに対して補強テープ線３により補強されているために、超電導特性が劣化することなく、また高温超電導線２と補強テープ線３の間に樹脂を含浸することが可能であるため、真空中での伝導による高温超電導線２の冷却が可能な補強高温超電導線１を提供できる。   According to the present embodiment, since the reinforcing tape wire 3 reinforces the force F for separating the layers of the high-temperature superconducting wire 2, the superconducting characteristics are not deteriorated, and the high-temperature superconducting wire 2 and the reinforcing tape wire. 3 can be impregnated with a resin, so that it is possible to provide a reinforced high-temperature superconducting wire 1 capable of cooling the high-temperature superconducting wire 2 by conduction in a vacuum.

FIG. 3 shows Example 2 according to the first embodiment of the reinforced high-temperature superconducting wire of the present invention, where (a) is a longitudinal sectional view taken along a plane perpendicular to the longitudinal axis direction, and (b) is (a). It is sectional drawing which expands and shows the high temperature superconducting wire shown by. In the high-temperature superconducting wire 2a of the reinforced high-temperature superconducting wire 1 shown as Example 2 in FIG. 3, the surface of the stabilizing layer 8 is disposed on the side where the reinforcing tape wire 3 is bent, and the surface of the metal substrate 4 is disposed on the opposite side. ing.

高温超電導線２aの中間層５は、一般的に絶縁物であるために、高温超電導線２aに通電するために、電気的に接続する場合には、基板側４ではなく、安定化層８もしくは安定化層８がない場合には保護層７と電気的に接続する必要がある。   Since the intermediate layer 5 of the high-temperature superconducting wire 2a is generally an insulator, in order to electrically connect the high-temperature superconducting wire 2a, when it is electrically connected, it is not the substrate side 4 but the stabilizing layer 8 or When there is no stabilizing layer 8, it is necessary to electrically connect with the protective layer 7.

本構成によれば、高温超電導線２aの安定化層８が、補強テープ線３で完全には覆われていないため、通電するために、リード線などと電気的に接続することが容易になる。   According to this configuration, since the stabilization layer 8 of the high-temperature superconducting wire 2a is not completely covered with the reinforcing tape wire 3, it is easy to electrically connect with a lead wire or the like for energization. .

したがって、本実施例によれば、高温超電導線２の安定化層８の面を補強テープ線３が折り曲げられた側に配置しているため、通電するために、リード線などと電気的に接続することが容易になる。   Therefore, according to the present embodiment, since the surface of the stabilization layer 8 of the high-temperature superconducting wire 2 is arranged on the side where the reinforcing tape wire 3 is bent, it is electrically connected to a lead wire or the like for energization. Easy to do.

（実施例３）
図４は、本発明の第１の実施形態の実施例３である補強高温超電導線１の断面を示している。第１の実施形態の実施例３として示す補強高温超電導線１の補強テープ線３aの折り曲げ部には、貫通孔９が形成されている。 (Example 3)
FIG. 4 shows a cross section of a reinforced high-temperature superconducting wire 1 that is Example 3 of the first embodiment of the present invention. A through hole 9 is formed in the bent portion of the reinforcing tape wire 3a of the reinforced high-temperature superconducting wire 1 shown as Example 3 of the first embodiment.

本実施例３によれば、補強高温超電導線１を巻回して高温超電導コイルを製作し、樹脂で含浸した場合に、樹脂は貫通孔９を介して、高温超電導線２と補強テープ線３の間に容易に入り込むことができる。   According to the third embodiment, when the reinforced high-temperature superconducting wire 1 is wound to manufacture a high-temperature superconducting coil and impregnated with a resin, the resin passes through the through-hole 9 and the high-temperature superconducting wire 2 and the reinforcing tape wire 3 Can easily get in between.

本実施例によれば、補強テープ線３に貫通孔９が形成されているため、真空中での伝導による高温超電導線２の冷却を可能にするために必要な高温超電導線２と補強テープ線３aの間の樹脂含浸をより確実に実施することができる。   According to the present embodiment, since the through hole 9 is formed in the reinforcing tape wire 3, the high temperature superconducting wire 2 and the reinforcing tape wire necessary to enable cooling of the high temperature superconducting wire 2 by conduction in a vacuum. The resin impregnation during 3a can be carried out more reliably.

なお、この実施例３に実施例１または２の構成である高温超電導線２、２aを適用できるのは勿論である。   Needless to say, the high temperature superconducting wires 2 and 2a having the configuration of the first or second embodiment can be applied to the third embodiment.

には、高温超電導線２の各部材間より剥離しやすい離形材１０が付加されている。 (Example 4)
FIG. 5 shows a cross section of a reinforced high-temperature superconducting wire 1 that is Example 4 of the first embodiment of the present invention. On the surface of the high-temperature superconducting wire 2 of the reinforced high-temperature superconducting wire 1 shown as Example 4 of the first embodiment, a release material 10 that is easily peeled off between the members of the high-temperature superconducting wire 2 is added.

本構成によれば、補強高温超電導線１を巻回して高温超電導コイル（図示せず）を製作し、高温超電導線２と補強テープ線３の間に樹脂を含浸した場合に、高温超電導線２の積層構造の層間を剥離させる力Ｆが働いたとしても、離形材１０が付加されているため、高温超電導線２の内部に力が伝わらず、この高温超電導線２内の層間が剥離するおそれを防止することができる。   According to this configuration, when the reinforced high-temperature superconducting wire 1 is wound to manufacture a high-temperature superconducting coil (not shown) and the resin is impregnated between the high-temperature superconducting wire 2 and the reinforcing tape wire 3, the high-temperature superconducting wire 2 Even if the force F for separating the layers of the laminated structure is applied, the release material 10 is added, so that no force is transmitted to the inside of the high-temperature superconducting wire 2 and the layers in the high-temperature superconducting wire 2 are separated. The fear can be prevented.

離形材１０としては、例えばテフロン（登録商標）などのフッ素系樹脂、パラフィングリース、シリコンオイルなどが用いられる。フッ素系樹脂を用いる場合は、フッ素系樹脂テープを用いることが好ましい。また、この離形材１０は表面全体である必要はなく効果が奏する部分に設けることも可能である。   As the release material 10, for example, a fluorine resin such as Teflon (registered trademark), paraffin grease, silicon oil, or the like is used. When using a fluororesin, it is preferable to use a fluororesin tape. Further, the release material 10 does not have to be the entire surface, and can be provided in a portion where the effect is exerted.

また、補強テープ線３の表面に離形材１０を付加しても同様の効果が得られる。   Moreover, even if the release material 10 is added to the surface of the reinforcing tape wire 3, the same effect can be obtained.

本実施例によれば、高温超電導線２と補強テープ線３の間で高温超電導線２もしくは補強テープ線３の表面または表面の一部に離形材１０が配置または塗布された離形処理が成されているため、高温超電導線２の積層構造の層間を剥離させる力Ｆが働いたとしても、高温超電導線２の層間が剥離するおそれを防止することができる。   According to the present embodiment, the mold release treatment in which the release material 10 is disposed or applied between the surface of the high temperature superconducting wire 2 or the reinforcing tape wire 3 or a part of the surface between the high temperature superconducting wire 2 and the reinforcing tape wire 3 is performed. Therefore, even if the force F for separating the layers of the laminated structure of the high-temperature superconducting wire 2 is applied, the possibility that the layers of the high-temperature superconducting wire 2 are separated can be prevented.

なお、この実施例４に実施例１から実施例３の構成を適用できるのは勿論である。   Needless to say, the configurations of the first to third embodiments can be applied to the fourth embodiment.

（実施例５）
図６は、本発明の第１の実施形態の実施例５である補強高温超電導線１の断面を示している。第１の実施形態の実施例５として示す補強高温超電導線１の高温超電導線２と補強テープ線３は、半田１１で接続されている。なお、半田１１の接続箇所は全面に接続した例で示しているが各々その一部（補強高温超電導線１の長手軸方向の一部または長手軸方向と垂直方向の一部）が電気的に接続されていれば良いのは勿論である。 (Example 5)
FIG. 6 shows a cross section of a reinforced high-temperature superconducting wire 1 that is Example 5 of the first embodiment of the present invention. The high temperature superconducting wire 2 and the reinforcing tape wire 3 of the reinforcing high temperature superconducting wire 1 shown as Example 5 of the first embodiment are connected by solder 11. In addition, although the connection part of the solder 11 is shown in the example connected to the whole surface, each part (part of the longitudinal direction of the reinforced high-temperature superconducting wire 1 or a part perpendicular to the longitudinal axis direction) is electrically. Of course, it is only necessary to be connected.
