定動索があり／こ。Conventionally, a thermal superconducting switch that realizes a resistance state (OFF) and a non-resistance state (ON) by heating and cooling a conductive wire has often used a non-winding switch alone. However, in the ON state, there was an unexpected slight heat input inside the switch and 1 ((', at 1119 minutes of flow introduction).

振７１７ノ＋・衝撃によってひきおこされていた。This unexpected slight heat input was mostly due to the movement of the superconducting wire inside the switch and at the πL flow introduction part.〇This movement of the superconducting wire was caused by the movement of the superconducting wire on the i day. First name =
4) It was caused by a resistive force or an external shock to the switch.
このような、スイッチＯＮ状態の不安定性を少なくする
ため、第１図に示すように無４ガ棉ネ欠きスイッチ１，

ことも試みられていた。この場合はＯＮ状態において、
複数個のスづツテ１，２゜３．４のうちの１個がＯＦＦ
状態に転移しでも、他のスイッチがＯＮ状態を保つので
、ＯＮ状態の安定性はスイッチを単独で用いる場、合に
比しで向上した。In order to reduce the instability of the switch ON state, as shown in FIG.
Attempts have also been made to stack a plurality of 2.2 and 3.4 tubes together and electrically connect them in parallel. In this case, in the ON state,
One of the multiple studs 1, 2, 3, and 4 is OFF.
Since the other switches remain in the ON state even when the state changes, the stability of the ON state is improved compared to when only one switch is used.

働らく力か強い場合は、全並列スイッチ１，２゜３．４
が一斉にＯＦＦ状態に転移するという可能性もあった。However, in the parallel-coupled switch structure shown in Figure 1, the forces acting on each switch 1, 2, 3. , if the force acting on S*f is strong, all parallel switches 1, 2° 3.4
There was also a possibility that all of them would transition to the OFF state all at once.
この発明は、超電導線に働らく力が強い場合にもＯＦＦ
状態に転移する可能性が極めて少ない超電導スイッチを
提供するにある。This invention can be turned off even when the force acting on the superconducting wire is strong.
The object of the present invention is to provide a superconducting switch that has an extremely low possibility of transitioning to a state.
この発明は、従来の無誘導巻きスイッチ積み重ね方式に
かわって誘導巻き各スイッチの通電方向が逆転するよう
に電気的並列結合し、初数個積み重ねる方式を採る事に
よって目的を達成している。The present invention achieves the object by adopting a method in which, instead of the conventional stacking method of non-inductively wound switches, each switch is electrically connected in parallel so that the direction of conduction of each inductively wound switch is reversed, and the first few switches are stacked.
この発明の具体的実施例を第２図にもとづいて説明する
。A specific embodiment of this invention will be described based on FIG.
第２図は４個並列のスイッチ５，６，７．８の例である
が同じ単−誘導巻きスイッチ５，６，７．８′ｆｃ交互
に通電方向が逆になるように並列電気結合している。Figure 2 shows an example of four switches 5, 6, 7.8 in parallel, and the same single-induction winding switches 5, 6, 7.8'fc are electrically connected in parallel so that the current direction is alternately reversed. ing.

スイッチと全く同じ柘４気的扱いが可能となる。With this configuration, the electromagnetic force acting on the superconducting wire and the force due to vibration and impact from the applied parts are different between the alternating single switches 5, 6, and 7.8, so all the parallel switches 5, 6, and 7
．． The possibility of all 8 transitioning to the OFF autumn state all at once is extremely low. In addition, the switches 5, 6, and 7.8 on each car have inductance due to induction winding, but if they are configured as shown in Figure 2, there is no inductance, and the switches are exactly the same as conventional non-induction winding switches. It becomes possible to handle it.

チを提供出来る。By carrying out the present invention, it is possible to provide a stable superconducting switch at a lower cost than that of a non-inductive winding of a winding heel.
