本発明は、超電導導体に係り、特に、超電導磁石を作る
とき、電磁力による動きを抑えるため、超電導導体間を
強固に連結するのに好適な導体構造に関する。[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to superconducting conductors, and in particular, a method suitable for strongly connecting superconducting conductors in order to suppress movement caused by electromagnetic force when making a superconducting magnet. Regarding conductor structure.
超電導磁石を作るための、超電導導体の中で、近年、特
に注目されているものに、一般にバンドル形導体と呼ば
れる構造の導体かめる。Among the superconducting conductors used to make superconducting magnets, one that has received particular attention in recent years is a conductor with a structure generally called a bundle-type conductor.

＆−Ｆれス旙論部炒め巾に勧めた鰭浩のえのである。For example, as shown in Figure 1, it is a bundle made of twisted thin wires made of superconducting materials, which is a combination of wires made of superconducting materials. be.
この構造は、超電導より線ｌの長手方向の引張強度が弱
いため、それを補強部材２で補なうことケ主な目的とし
て考案されたものであるが、通常、コンジットとより線
の間および、エリ線同士の間のわずかな隙間に、冷却媒
体ケ流す強制冷却方式にも使用される。This structure was devised primarily to compensate for the weak longitudinal tensile strength of the superconducting strands 1 with the reinforcing member 2, but it is usually It is also used in forced cooling systems in which the cooling medium flows through the small gaps between the edge wires.
この形の導体は、従来の中実導体と比較して、大電流？
流すことができる利点があるが、一方その大′ｔＪＬ＃
、のために、導体に発生する電磁力もまた強大になる。Does this type of conductor have a higher current than a conventional solid conductor?
It has the advantage of being able to flow, but on the other hand, its large 'tJL#
, the electromagnetic force generated in the conductor also becomes stronger.
従って、その電磁力に対して特に考慮する必要かめる。Therefore, special consideration must be given to the electromagnetic force.
超電導磁石を作る場合、一般に、導体をパンケーキ巻き
、或いは、ソレノイド巻きとしてコイルケ作るか、その
巻線において、導体の各層間に隙間のないコイル？作る
ことは、事実上不可能である。When making a superconducting magnet, generally the conductor is coiled by pancake winding or solenoid winding, or the coil is wound with no gaps between each layer of the conductor. It is virtually impossible to create.
しかし、この導体間の隙間の大小は、超電導磁石の性能
？左右する重要な因子で返る。However, does the size of the gap between the conductors determine the performance of the superconducting magnet? Returns with important influencing factors.
即ち、通電により電磁力が発生したとき、導体間に隙間
がおると、導体は電磁力の方向に移動する。そのため、
それに伴って、導体のひずみが増加するので、超電導導
体の性能が低下してしまう。That is, when an electromagnetic force is generated by energization, if a gap is created between the conductors, the conductors move in the direction of the electromagnetic force. Therefore,
Along with this, the strain in the conductor increases, resulting in a decrease in the performance of the superconducting conductor.
従来、中実導体の場合は、この隙間ケ、樹脂含浸によっ
て埋め、或いは、ＦＲＰの薄板？隙間に合わせて挿入す

これらの方法は、大電流、大電磁力の場合には、もはや
充分でない。Conventionally, in the case of a solid conductor, this gap was filled with resin impregnation, or with a thin FRP plate. Replenishment has been carried out by methods such as inserting it into the gap. but,
These methods are no longer sufficient in the case of large currents and large electromagnetic forces.
それは、電磁力によって、充填物に圧縮変形を生じ、そ
の変形量が無視できない値になってしまうからでろる。This is because the electromagnetic force causes compressive deformation of the filling, and the amount of deformation becomes a value that cannot be ignored.
本発明の要点は、充填物を強度の高い材料に変え、更に
、所定の初期圧力？与えて挿入できるよう楔形にするの
に好適なように、導体の角部に斜面ケ設けたことにある
。The key point of the present invention is to change the filling material to a high-strength material, and also to maintain a predetermined initial pressure. The conductor is provided with beveled edges at its corners so as to be suitable for wedge-shaped insertion.
第１図および第２図に本発明の実施例ケ示す。 Embodiments of the present invention are shown in FIGS. 1 and 2.
第１図は、導体の断面図？示し、超電導線よりなるより

材２の角部に斜面３ヶ設けている。Is Figure 1 a cross-sectional view of a conductor? IJ! 1 and a reinforcing member 2 enclosing the reinforcing member 2, and three slopes are provided at the corners of the reinforcing member 2.
この導体を使用してコイル？作った場合の例全第２図に

＠間に楔４七打込み、所定の初期面圧？与えて導体間を
連結する。Coil using this conductor? An example of how it is made is shown in Figure 2. Is the diagram part of a pancake coil? and each I of the conductor
@ Drive 47 wedges in between, specified initial surface pressure? to connect conductors.
このときの楔の初期面圧？、電磁力が加わったときの圧
力以上に設定しておけば、各導体は、見かけ上、連続体
のように挙動するので、導体の動＠量ケ最小限に抑制で
きる。What is the initial surface pressure of the wedge at this time? If the pressure is set to be higher than the pressure when electromagnetic force is applied, each conductor will apparently behave like a continuum, so the movement of the conductor can be suppressed to a minimum.
楔４は、このときの圧力に耐える絶縁物５、例えば、セ
ラミック等ケ使用し、また、抜は出し防止のため、接着

りに溶接を用いても差し支えない。The wedge 4 is made of an insulating material 5, such as ceramic, that can withstand the pressure at this time, and is fixed at the same time as being driven using an adhesive to prevent it from being pulled out. However, this wedge may be made of insulated metal, and in that case, welding may be used instead of adhesion.
また、本実施例は、斜面ヶ二ケ所に設けているが、四ケ
所でも同様の効果がある。Further, in this embodiment, the slopes are provided at two locations, but the same effect can be obtained with four locations.
