しかしながら、上記した渦電流損失の測定方法では、図６に示すような超電導磁気浮上式鉄道においてガイドウエイの地上コイル導体の渦電流損失を模擬測定するには不向きであり、満足のいく渦電流損失評価がなされていないのが現状である。   However, the above eddy current loss measurement method is not suitable for simulating the eddy current loss of the ground coil conductor of the guideway in a superconducting magnetic levitation railway as shown in FIG.

以下、本発明の実施の形態について詳細に説明する。   Hereinafter, embodiments of the present invention will be described in detail.

図１は本発明の第１実施例を示す移動磁界中における導体の渦電流損失の模擬測定装置の模式図、図２はそれを用いた渦電流損失の算出フローチャートである。   FIG. 1 is a schematic diagram of an apparatus for simulating the measurement of eddy current loss of a conductor in a moving magnetic field according to a first embodiment of the present invention, and FIG. 2 is a flowchart for calculating eddy current loss using the apparatus.

図１において、１は回転軸、２は回転軸１に固定される非磁性・非導電性の回転円板、３〜１０は電磁石であり、それぞれ１組の対向した電磁石が固定部材に固定されており、それらの固定された電磁石間のギャップを回転円板２が通過する。また、電磁石３〜１０には、直流電流が通電され、隣接する電磁石３と４，４と５，５と６，６と７，７と８，８と９，９と１０はそれぞれ逆極性となるように配置されている。１１は非磁性・導電性の供試体であり回転円板２に固定される。なお、図示していないが、回転軸１には回転トルク計が接続される。   In FIG. 1, 1 is a rotating shaft, 2 is a non-magnetic / non-conductive rotating disk fixed to the rotating shaft 1, and 3 to 10 are electromagnets, each having a pair of opposed electromagnets fixed to a fixing member. The rotating disk 2 passes through the gap between the fixed electromagnets. The electromagnets 3 to 10 are supplied with a direct current, and the adjacent electromagnets 3, 4, 4, 5, 5, 6, 6, 7, 7, 8, 9, 9, and 10 have opposite polarities. It is arranged to be. Reference numeral 11 denotes a nonmagnetic / conductive specimen, which is fixed to the rotating disk 2. Although not shown, a rotary torque meter is connected to the rotary shaft 1.

ここで、超電導磁気浮上式鉄道における地上コイル導体に供試体１１が対応し、超電導磁気浮上式車両に搭載される超電導磁石が電磁石３〜１０に対応する。つまり、超電導磁気浮上式鉄道の構成とは相対的に逆になっているが、供試体１１が地上側に固定され、電磁石３〜１０が超電導磁気浮上式車両に搭載され移動することと同じになり、実際の発生原理と同様な移動磁場により渦電流損失を測定することができる。   Here, the specimen 11 corresponds to the ground coil conductor in the superconducting magnetic levitation railway, and the superconducting magnets mounted on the superconducting magnetic levitation vehicle correspond to the electromagnets 3 to 10. That is, the configuration of the superconducting magnetic levitation railway is relatively opposite, but the specimen 11 is fixed on the ground side, and the electromagnets 3 to 10 are mounted on the superconducting magnetic levitation vehicle and move. Thus, eddy current loss can be measured by a moving magnetic field similar to the actual generation principle.

このように構成することにより、電磁石３〜１０の無励磁時、つまり、地上コイル側に導電体が存在していない（全く残されていない）場合と同じ状態の回転トルクと、電磁石３〜１０の励磁時、つまり、地上コイル側に導電体が存在している（導電体が残されている）場合と同じ状態の回転トルクとを求めて、両者の回転トルクの差により渦電流損失を算出する。   By configuring in this way, the rotational torque in the same state as when the electromagnets 3 to 10 are not excited, that is, when no conductor is present on the ground coil side (nothing is left), and the electromagnets 3 to 10 are used. Rotation torque in the same state as when there is a conductor on the ground coil side (the conductor is left), and eddy current loss is calculated from the difference between the two torques To do.

渦電流損失の算出手順は、図２に示すように、まず、（１）電磁石３〜１０の無励磁時の回転トルク（Ａ）の計測を行い（ステップＳ１）、次いで（２）電磁石３〜１０の励磁時の回転トルク（Ｂ）を行い（ステップＳ２）、（３）上記で計測した回転トルク（Ｂ）と回転トルク（Ａ）との差により供試体１１による渦電流損失の算出を行う（ステップＳ３）。   As shown in FIG. 2, the calculation procedure of the eddy current loss is as follows: (1) Measure the rotational torque (A) when the electromagnets 3 to 10 are not excited (step S1), and then (2) electromagnets 3 to 3. 10 is performed (step S2), and (3) eddy current loss due to the specimen 11 is calculated based on the difference between the rotational torque (B) and the rotational torque (A) measured above. (Step S3).

図３は本発明の第２実施例を示す移動磁場中における導電体の渦電流損失の模擬測定装置の模式図、図４はそれを用いた渦電流損失の算定フローチャートである。   FIG. 3 is a schematic diagram of an apparatus for simulating measurement of eddy current loss of a conductor in a moving magnetic field according to a second embodiment of the present invention, and FIG. 4 is a calculation flowchart of eddy current loss using the same.

図３において、２１は回転軸、２２は回転軸２１に固定される上部回転円板、２３は回転軸２１に固定される下部回転円板である。２４〜３１は上部回転円板２２と下部回転円板２３とに対になって固定された永久磁石であり、隣接する電磁石２４と２５，２５と２６，２６と２７，２７と２８，２８と２９，２９と３０，３０と３１は逆極性となるように配置されている。３２は非磁性・導電性の供試体であり、上部回転円板２２と下部回転円板２３とのギャップ中に固定されている。なお、図示していないが、回転軸２１には回転トルク計が接続される。   In FIG. 3, 21 is a rotating shaft, 22 is an upper rotating disk fixed to the rotating shaft 21, and 23 is a lower rotating disk fixed to the rotating shaft 21. Reference numerals 24 to 31 are permanent magnets fixed to the upper rotating disk 22 and the lower rotating disk 23 in pairs, and adjacent electromagnets 24 and 25, 25 and 26, 26 and 27, 27 and 28, 28, 29, 29 and 30, 30 and 31 are arranged to have opposite polarities. Reference numeral 32 denotes a nonmagnetic / conductive specimen, which is fixed in the gap between the upper rotating disk 22 and the lower rotating disk 23. Although not shown, a rotary torque meter is connected to the rotary shaft 21.

本実施例では、永久磁石２４〜３１を回転円板２２，２３に固定し（超電導磁気浮上式車両に搭載される超電導磁石に相当）、上部回転円板２２及び下部回転円板２３の間に固定された供試体３２（地上コイル側の導電体に相当）近傍を通過させるように構成した。ここでは、供試体３２の有無による回転トルクの差により渦電流損失を測定する。   In this embodiment, the permanent magnets 24 to 31 are fixed to the rotating disks 22 and 23 (corresponding to a superconducting magnet mounted on a superconducting magnetic levitation vehicle), and between the upper rotating disk 22 and the lower rotating disk 23. The fixed specimen 32 (corresponding to the conductor on the ground coil side) was passed in the vicinity. Here, eddy current loss is measured by the difference in rotational torque depending on the presence or absence of the specimen 32.

渦電流損失の算出手順は、図４に示すように、まず、（１）永久磁石２１〜３１を有する２枚の回転円板２２，２３を回転させて、回転トルク（Ａ）の計測を行い（ステップＳ１１）、次いで、（２）２枚の回転円板２２，２３の間のギャップに固定部材（図示なし）に固定された供試体３２を設定して回転トルク（Ｂ）の計測を行い（ステップＳ１２）、（３）上記で計測した回転トルク（Ｂ）と回転トルク（Ａ）との差により供試体３２による渦電流損失の算出を行う（ステップＳ１３）。   As shown in FIG. 4, the eddy current loss calculation procedure is as follows: (1) Rotating the two rotating disks 22 and 23 having the permanent magnets 21 to 31 to measure the rotational torque (A). (Step S11), (2) Then, the specimen 32 fixed to a fixing member (not shown) is set in the gap between the two rotating disks 22 and 23, and the rotational torque (B) is measured. (Step S12), (3) The eddy current loss by the specimen 32 is calculated based on the difference between the rotational torque (B) and the rotational torque (A) measured above (Step S13).

図５は具体化された移動磁場中における導電体の渦電流損失の模擬測定装置の模式図であり、図５（ａ）は供試体が存在しない状態を示す図、図５（ｂ）は供試体が存在する状態を示す図である。   FIG. 5 is a schematic diagram of a simulation apparatus for eddy current loss of a conductor in a specific moving magnetic field. FIG. 5 (a) is a diagram showing a state in which no specimen is present, and FIG. It is a figure which shows the state in which a sample exists.

これらの図において、４１は回転軸、４２は回転軸４１に固定された非磁性・非導電性の回転円板、４３は回転軸４１に設けられる回転トルク計、４４は回転円板４２を駆動する、回転軸４１に接続されるモーター、４５，４６はコの字形状の固定部材であり、互いに対向するように配置されている。４７，４８はコの字形状の固定部材４５，４６に回転円板４２を挟んで上下に対向するように配置される電磁石である。回転円板４２は上下に対になった電磁石の間を回転するように構成されている。つまり、回転円板４２には電磁石４７，４８によって磁場が印加されるように構成されている。   In these drawings, reference numeral 41 denotes a rotating shaft, 42 denotes a non-magnetic / non-conductive rotating disc fixed to the rotating shaft 41, 43 denotes a rotational torque meter provided on the rotating shaft 41, and 44 drives the rotating disc 42. The motors 45 and 46 connected to the rotary shaft 41 are U-shaped fixing members and are arranged so as to face each other. Reference numerals 47 and 48 denote electromagnets arranged so as to be opposed to each other vertically with a rotating disk 42 sandwiched between U-shaped fixing members 45 and 46. The rotating disk 42 is configured to rotate between a pair of upper and lower electromagnets. That is, a magnetic field is applied to the rotating disk 42 by the electromagnets 47 and 48.

このように構成したので、まず、図５（ｂ）に示すように、供試体４９を回転円板４２に固定して、電磁石４７，４８を励磁しない状態で回転円板４２を回転させて、その時の回転トルク計４３によるトルク値を求めておき、次いで、電磁石４７，４８を励磁した状態で回転円板４２を回転させて、その時の回転トルク計４３によるトルク値を求める。   Since it comprised in this way, first, as shown in FIG.5 (b), the specimen 49 is fixed to the rotation disc 42, the rotation disc 42 is rotated in the state which does not excite the electromagnets 47 and 48, A torque value by the rotational torque meter 43 at that time is obtained, and then the rotating disk 42 is rotated in a state where the electromagnets 47 and 48 are excited, and a torque value by the rotational torque meter 43 at that time is obtained.

すると、電磁石４７，４８の励磁の有無により、回転トルク計４３により測定されるトルク値が異なる。また、供試体４９の量が多くなるほどトルク値が増大することになり、このトルク値の増加分が導電体としての供試体４９による渦電流損失に比例することになる。   Then, the torque value measured by the rotational torque meter 43 varies depending on whether the electromagnets 47 and 48 are excited. Further, as the amount of the specimen 49 increases, the torque value increases, and the increase in the torque value is proportional to the eddy current loss due to the specimen 49 as a conductor.

したがって、移動磁場中における導電体の渦電流損失の模擬測定を行うことができ、その結果を、超電導磁気浮上式鉄道における地上コイル導体の渦電流損失の評価に用いることができる。   Therefore, the eddy current loss of the conductor in the moving magnetic field can be simulated, and the result can be used to evaluate the eddy current loss of the ground coil conductor in the superconducting magnetic levitation railway.

すなわち、図５において、電磁石４７，４８が超電導磁気浮上式鉄道車両に搭載される超電導磁石に対応し、回転円板４２が地上コイルを有するガイドウェイの側壁に対応し、供試体４９はその側壁に配置された地上コイル導体などの導電体に対応する。   That is, in FIG. 5, the electromagnets 47 and 48 correspond to the superconducting magnets mounted on the superconducting magnetic levitation railway vehicle, the rotating disk 42 corresponds to the side wall of the guideway having the ground coil, and the specimen 49 is the side wall. Corresponds to a conductor such as a ground coil conductor disposed in

そこで、ガイドウェイの側壁に供試体としての導電体が多く存在する場合には、その導電体の量を供試体の量として設定することにより、供試体による渦電流損失として測定することができる。これにより、ガイドウェイの側壁に配置された導電体としての供試体と、超電導磁気浮上式鉄道車両に搭載される超電導磁石としての電磁石との関係に基づいて、ガイドウェイの側壁に配置された導電体の渦電流損失の程度を推定し計測することができる。   Therefore, when there are many conductors as specimens on the side walls of the guideway, it is possible to measure the eddy current loss due to the specimen by setting the amount of the conductor as the quantity of the specimen. Thus, based on the relationship between the specimen as the conductor disposed on the side wall of the guideway and the electromagnet as the superconducting magnet mounted on the superconducting magnetic levitation railway vehicle, the electrical conductivity disposed on the side wall of the guideway. The degree of eddy current loss of the body can be estimated and measured.
