本発明は、誘導反発形磁気支持及びヌルフラックス磁気
案内方式の磁気浮上列車において、車両に搭載した超電
導磁石装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a superconducting magnet device mounted on a vehicle in a magnetic levitation train using induced repulsion magnetic support and null flux magnetic guidance.
従来のＭｉ磁気浮上列車おける超電導磁石装置は、車内

ッチコにより閉回路が構成されている。 。The superconducting magnet device in the conventional Mi magnetic levitation train is mounted symmetrically under the floor inside the train, and each superconducting coil (hereinafter referred to as a coil) is installed in either one or 4il! Within several ranges, the first
As shown in the figure (&), a closed circuit is constructed by a permanent electric value switch for each of the 11 coils. .

された案内用地上コイルＪ。If there is no abnormality in the superconducting magnet device, and the train is being supported and guided by the magnetic levitation blades and magnetic guiding force and is levitating with slight displacement near the equilibrium position, then Guide ground coil J connected by null flux with null 7 sixes line.

案内用地上コイルＪ１あるいはコイルｌ′と案内用地上
コイル３′間の電磁力も小さい。A magnetic flux j%S' having almost the same magnitude and opposite sign intersects l. Therefore, the magnitude of the current generated in the guiding ground coil J%J' is proportional to the sum of the linkage magnetic fluxes JSj' of the seven pairs of left and right guiding ground coils 3.3' connected in a null-flutter chain. Therefore, the electromagnetic force between the coil l and the guiding ground coil J1 or between the coil l' and the guiding ground coil 3' is also small.

程度にもなり、大きな事故の原因となる可能性がある。However, if for some reason the coil I' quenches during running, the current in the fill door will attenuate rapidly, and the null 7 ratus state will be broken as shown in Figure 1 (6).
L pair of left and right guiding ground coils 313' and null flux &! A large magnetic flux j interlinks with the circuit composed of
As a result, a large current is induced and a large X magnetic repulsion force is generated between the coil 1 and the guiding ground coil 3. When we calculated this electromagnetic repulsion force, we found that it is koM per coil.
This could lead to serious accidents.
本発明は、上記の欠点を除去するためになされたもので

を誘発することを除去できるようにしたものである。The present invention has been made to eliminate the above-mentioned drawbacks, and by electrically connecting the coils in series on the left and right sides, when any one coil generates a quench, the quenched coil is The current in the normal coils connected in series is also reduced at the same time, so large electromagnetic forces are not generated in the left and right directions, and the possibility of quenching the coils causing a major accident can be eliminated.
以下、本発明の実施例を図に従って説明する。Embodiments of the present invention will be described below with reference to the drawings.

力は発生しない。If seven pairs of left and right coils i and i' are connected in series as shown in Figure 1 (,), and an enclosure configuration in which the left and right pair of coils share a persistent current switch, Figure 1 (b) is obtained. As shown, under normal driving conditions, there is no difference at all from the conventional case. On the other hand, in the case shown in Figure 1 (0) where one coil l generates a quench, the -null flux state is maintained in the left and right pair of coils, and the IIa repulsion in the left and right direction is large as in the conventional case. No force is generated.

な電磁力は発生しないため、大きな事故となる要因を除
去することができる。As explained in the above embodiment, the superconducting magnet device according to the present invention has l pairs of left and right coils connected in series, so even if any one coil quenches, the coil currents of l pairs of left and right attenuate simultaneously. However, since an unbalanced electromagnetic force between the left and right sides is not generated, it is possible to eliminate the cause of a major accident.

去できることの効果は同様である。Although the guide system has been described in the above embodiment, the effect of removing unbalanced electromagnetic force generated between the left and right sides is the same for the levitation system as well.
