Description

【０００１】
【発明の属する技術分野】
本発明は磁気浮上列車の集電装置に係り、特に、浮上・推進力を作用させる超電導コイルの磁場で、浮上コイルに誘導させた高調波磁場を利用し誘導集電するようにした集電装置に関するものである。
【０００２】
【従来の技術】
従来一般に知られている磁気浮上列車の集電装置には、次の２通りのものが良く知られている。すなわち、集電専用として集電コイル上に取り付けられた超電導コイルの磁場で、浮上コイルに電流を誘導し、集電コイルで集電する集中集電方式のものと、浮上推進用の超電導コイルの磁場により、浮上コイルに生じる電流の高調波成分を、集電コイルで誘導し集電する分散集電方式のものである。
【０００３】
図３は、この誘導集電装置を備えた磁気浮上列車の概略構成を示すもので、１４が磁気浮上列車の車体であり、６がこの車体側に設けられている集電コイル装置である。磁気浮上列車の車体１４は、台車１の上に連結され、台車１の両側には、超電導コイル５を収容した外槽２が設けられている。また、この外槽２の地上側表面には、台車１の両側において集電コイル装置６が取り付けられており、地上の側壁１３には、地上コイル，すなわち浮上コイル１１と推進コイル１２が配置されている。
【０００４】
図４は、図３に示されている台車１の片側（図３右側）の拡大図で、磁気浮上列車は次のように動作する。すなわち、超電導コイル５により作り出された磁場が、地上コイルである推進コイル１２との吸引・反発作用により磁気浮上列車は推進し、そして推進している状態で超電導コイル５の磁場の中心が、８の字状に形成されている浮上コイル１１の中心位置より下に下がると、浮上コイル１１には誘導電流が流れ、超電導コイル５と浮上コイル１１の磁場の中心位置を一致させようとする浮上力が作用し、台車１は浮上しながら走行することになる。
【０００５】
また、磁気浮上列車の分散形誘導集電装置は、進行方向に離散的に取り付けられた８の字形状となっている浮上コイル１１により発生する磁場の高調波成分に対して、誘導電流が流れるような位置に集電コイルを置くことにより集電動作が行なわれる。この場合、８の字形状に形成された集電コイル７の中心位置は、超電導コイル５の中心位置に、ある程度一致するよう取り付けられており、磁気浮上列車が浮上走行している際は、浮上コイル１１と集電コイル６との中心位置は一致しないため、集電コイル７には浮上コイル１１による誘導電流が生じることになり、集電が行われる。
【０００６】
なお、この種の誘導集電装置に関連するものとしては、例えば特開平１０−８３９１６号公報あるいは特開平８−１１１９１号公報などが挙げられる。
【０００７】
【発明が解決しようとする課題】
このように形成されている磁気浮上列車の誘導集電装置，すなわち浮上推進用の超電導コイル５の磁場による集電方式での集電能力は、磁気浮上列車の速度および超電導コイル５の中心位置と浮上コイル１１の中心位置に対する沈み込み量に大きく依存されることになる。例えば、磁気浮上列車が、乗客が満員で相対速度５００ｋｍ／ｈでの走行時と乗客が空車で相対速度３００ｋｍ／ｈでの走行時では、集電量に大きな差が生じることになる。
【０００８】
そこで、磁気浮上列車に必要とされる空調、照明および冷凍機等の電気機器で最低限必要とされる電力量を考え、例えば、１台車当たりの集電能力に関する設計仕様としては、空車時で相対速度３００ｋｍ／ｈでの走行時でも、５０ｋＷ以上の集電能力が必要とされている。
【０００９】
図５には、図３に示す台車１の地上側より見た集電コイル装置６の概略構成が示されている。５０ｋＷ以上の集電能力を達成するためには、図５に示されているように、外槽２全面に集電コイル装置６を取り付けることが必要とされる。集電能力は、浮上コイル１１から集電コイル７までにおける距離の４乗で集電量は変化することから、集電量を増加させるためには、集電コイル７をできるだけ浮上コイル１１側に近づけることが必要である。
【００１０】
また、浮上コイル１１による変動磁場は外槽２の表面に渦電流を生じさせ、この渦電流により磁場の高調波成分が減少してしまい、集電能力を低下させてしまう。以上のことから、集電コイル７はできるだけ浮上コイル１１側に近づけ、かつ超電導磁石外槽２表面から離さなければならない。ところで、集電コイル装置６の取り付け位置は、超電導コイル５の中心から集電コイル装置６の表面まで車両限界他により例えば８０ｍｍと決まっている。
【００１１】
また、磁気浮上列車の走行時においては、超電導コイル５の強力な磁場による磁性体の吸引、走行の風圧による飛び石等で集電コイル７への損傷が与えられ、電気的対地絶縁破壊を起こす可能性がある。特に、走行の風圧による飛び石等は高速走行になるに従い、集電コイル７に与える衝撃エネルギーは増す。そこで表面部材９に厚さを持たせることで機械的強度を高めることが考えられるが、表面部材９の厚さが増すと集電コイル７と浮上コイル１１との距離が増すことになり集電能力が低下する。このことから、集電コイル装置６は集電能力を高めるために地上コイル側表面を薄くする必要があり、電気的対地絶縁性能を向上させるような構造にしなければならないという問題がある。
【００１２】
本発明はこれに鑑みなされたもので、その目的とするところは、集電能力の向上を図ることができるとともに、衝撃物による集電コイル導体への損傷を充分防止することが可能な磁気浮上列車の集電装置を提供することにある。
【００１３】
【課題を解決するための手段】
すなわち本発明は、地上コイルに対向配置され、かつ車体に設けられた集電コイルと、この集電コイルを収納している集電コイル収納ケースとを備え、前記地上コイルと集電コイルとの誘導作用により集電を行うように形成されている磁気浮上列車の集電装置において、前記集電コイルと集電コイル収納ケースの内壁面との間に、電気的絶縁物の緩衝層を設けるようになし所期の目的を達成するようにしたものである。
【００１４】
また本発明は、地上コイルに対向配置され、かつ車体に設けられた集電コイルと、この集電コイルを収納している集電コイル収納ケースとを備え、前記地上コイルと集電コイルとの誘導作用により集電を行うように形成されている磁気浮上列車の集電装置において、前記集電コイルと集電コイル収納ケースの内壁面との間に、伸び特性が良好で、かつ電気的絶縁物の緩衝層を設けるようにしたものである。
【００１５】
また本発明は、地上コイルに対向配置され、かつ車体に設けられた集電コイルと、この集電コイルを収納している集電コイル収納ケースとを備え、前記地上コイルと集電コイルとの誘導作用により集電を行うように形成されている磁気浮上列車の集電装置において、前記集電コイルと集電コイル収納ケースの内壁面との間に、伸び特性が良好で、かつ電気的絶縁物の緩衝層を設けるとともに、前記集電コイル一体を樹脂で加圧含浸し硬化させるようにしたものである。
【００１６】
また本発明は、地上コイルに対向配置され、かつ車体に設けられた集電コイルと、この集電コイルを収納している集電コイル収納ケースとを備え、前記地上コイルと集電コイルとの誘導作用により集電を行うように形成されている磁気浮上列車の集電装置において、前記集電コイル収納ケースをガラス繊維強化プラスチックで形成するとともに、前記集電コイルと集電コイル収納ケースの内壁面との間全面に、伸び特性が良好で、かつ電気的絶縁物の緩衝層を設け、かつ前記集電コイルおよび前記収納ケースを樹脂で加圧含浸し硬化させるようにしたものである。
【００１７】
また、この場合、前記緩衝層を、ポリイミドフィルム、テフロンシートあるいはオレフィン系ポリマーで形成するようにしたものである。
【００１８】
すなわちこのように形成された磁気浮上列車の集電装置であると、集電コイルと集電コイル収納ケースの内壁面との間に、電気的絶縁物の緩衝層が設けられていることから、集電コイルの導体に与える衝撃エネルギーは緩衝層の伸びにより緩衝され、また、緩衝層が電気的絶縁物であることから、集電コイル収納ケースの表面側の厚さを薄くすることが可能となり、したがって集電能力の向上を図ることができ、かつ衝撃物による集電コイル導体への損傷を充分防止することが可能となるのである。
【００１９】
【発明の実施の形態】
以下図示した実施例に基づいて本発明を詳細に説明する。図１にはその集電装置を備えた磁気浮上列車および集電装置の要部が断面で示されている。１４が磁気浮上列車の車体であり、１３が地上側の側壁、５が超電導コイル、６が集電コイル装置、１１、１２が地上コイル，すなわち１１が浮上コイル、１２が推進コイルである。
【００２０】
浮上推進用の超電導コイル５は、外槽２内に、内槽４および荷重支持体３を介して支持され、そしてこの超電導コイル５により作り出された磁場が、地上側の側壁１３に取り付けられた浮上コイル１１および推進コイル１２にそれぞれ浮上方向、推進方向に吸引・反発力を作用させ、磁気浮上列車は磁気浮上走行をする。集電コイル装置６は、図５に示されているように、外槽２の表面の地上側で外槽表面全体に取り付けられている。勿論、台車１を挟んだ反対側も同様な構成になっている。
【００２１】
図１（ｂ）は、この集電コイル装置６の断面を拡大して示したもので、この図に示されているように、集電コイル装置６は、集電コイル７とこの集電コイル７を収納している集電コイル収納ケース１８とから構成され、また、この集電コイル収納ケース１８は、表面部材９と裏板１０から構成されている。すなわち、集電コイル７は、集電コイル７が収納されるように加工された表面部材９の内部に収納されているのである。
【００２２】
また、この場合、特にこの集電コイル７と表面部材９との間には緩衝材（緩衝層）８が設けられている。換言すれば、表面部材９の凹部に緩衝材８が敷かれ、この緩衝材８の上に集電コイル７が配置されている。そしてその上に裏板１０が張り付けられている。
【００２３】
なお、この場合、さらに集電コイル装置６一体を樹脂で加圧含浸し硬化させるようにすると良好である。また、この実施例では一側（地上コイルに近い側）に緩衝材８を設けるようにしたが、常にこのようにしなければならないわけではなく、図２に示すように、集電コイル７と裏板１０の間にも緩衝材８を挿入するようにしてもよい。勿論、この場合においても、集電コイル装置６一体を樹脂で加圧含浸し硬化させるようにすると良い。また、この場合、この集電コイル７を収納する表面部材９、裏板１０としては、機械的強度を持ったガラス繊維強化プラスチック（ＧＦＲＰ）を使用する。
【００２４】
緩衝材８としては、伸びのある電気的絶縁物が良く、例えば、ポリイミド系素材であるカプトン、テフロン、オレフィン系ポリマーであるＥＣＯ・ライトシート等が用いられる。特に、この種の材料であると、表面部材９の厚さを薄くすることが可能となるため、集電能力の向上が図れる。
【００２５】
以上説明してきたようにこのように形成された誘導集電装置であると、集電コイル７と表面部材９との間に、緩衝材８が介在されていることから、集電コイル７に与える衝撃エネルギーは緩衝材８の伸びにより緩衝され、また、緩衝材８が電気的絶縁物で、伸びのあるものであることから、表面部材９の厚さを薄くすることが可能となるため、集電能力の向上が図れる。
【００２６】
また、表面部材９にＧＦＲＰ材を用いている場合には、金属物等の物体が相当の衝撃エネルギーで表面部材９に当たった場合、その衝突箇所はＧＦＲＰの脆性変形により、凹みとともに集電コイル７に達する微小な欠陥が生じることがあり、湿潤環境下ではその欠陥部に水分が浸透し、集電コイル７とアース間での地絡が生じる可能性があるが、しかし、電気的絶縁を保つ伸びのある緩衝材８があることにより、集電コイル装置６に衝撃物が当たった場合でも、緩衝材８の伸びの効果によって、緩衝材８には穴があきにくく、電気的絶縁材であることから、集電コイル７とアース間での地絡が起きにくいという効果がある。
【００２７】
さらに、図２に示されているように、集電コイル７と裏板１０の間にも電気的絶縁材を保つ伸びのある緩衝材８を挿入した場合には、集電コイル７に与える衝撃エネルギーの緩衝がさらに図られるという効果がある。
【００２８】
【発明の効果】
以上説明してきたように本発明によれば、集電能力の向上を図ることができるとともに、衝撃物による集電コイルへの損傷を充分防止することが可能な磁気浮上列車の集電装置を得ることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a current collector for a magnetically levitated train, and more particularly, a current collector that uses a harmonic magnetic field induced in a levitating coil to inductively collect current using a magnetic field of a superconducting coil that causes levitating / propulsive force to act. It is about.
[0002]
[Prior art]
Conventionally known magnetic levitation train current collectors are well known in the following two ways. In other words, the magnetic field of the superconducting coil attached on the current collecting coil exclusively for current collection induces current in the levitation coil and collects current with the current collecting coil, and the superconducting coil for levitation propulsion. This is a distributed current collecting system in which a harmonic component of a current generated in a levitation coil is induced by a current collecting coil and collected by a magnetic field.
[0003]
FIG. 3 shows a schematic configuration of a magnetic levitation train provided with this induction current collector. 14 is a vehicle body of the magnetic levitation train, and 6 is a current collecting coil device provided on the vehicle body side. The body 14 of the magnetic levitation train is connected to the carriage 1, and the outer tank 2 containing the superconducting coil 5 is provided on both sides of the carriage 1. Further, current collecting coil devices 6 are attached to the ground side surface of the outer tub 2 on both sides of the carriage 1, and ground coils, that is, the levitation coil 11 and the propulsion coil 12 are disposed on the ground side wall 13. ing.
[0004]
FIG. 4 is an enlarged view of one side (right side of FIG. 3) of the carriage 1 shown in FIG. 3, and the magnetic levitation train operates as follows. That is, the magnetic levitation train is propelled by the magnetic field generated by the superconducting coil 5 by the attraction and repulsion action with the propulsion coil 12 that is a ground coil, and the center of the magnetic field of the superconducting coil 5 is 8 When the levitation coil 11 is lowered below the center position of the levitation coil 11, an induced current flows through the levitation coil 11, and the levitation force tries to match the center positions of the magnetic fields of the superconducting coil 5 and the levitation coil 11. As a result, the carriage 1 travels while rising.
[0005]
In addition, the distributed induction current collector of the magnetic levitation train causes an induced current to flow in the harmonic component of the magnetic field generated by the levitation coil 11 having an 8-shaped shape discretely attached in the traveling direction. The current collecting operation is performed by placing the current collecting coil at such a position. In this case, the central position of the current collecting coil 7 formed in the shape of the figure 8 is attached to coincide with the central position of the superconducting coil 5 to some extent, and when the magnetic levitation train is flying, Since the center positions of the coil 11 and the current collecting coil 6 do not coincide with each other, an induced current is generated in the current collecting coil 7 by the levitation coil 11 and current collection is performed.
[0006]
In addition, as what is related to this type of induction current collector, for example, JP-A-10-83916 or JP-A-8-11191 can be cited.
[0007]
[Problems to be solved by the invention]
The current collection capability of the magnetically levitated train inductive current collecting device, that is, the current collecting method by the magnetic field of the superconducting coil 5 for levitation propulsion, is determined by the speed of the magnetic levitation train and the center position of the superconducting coil 5. This greatly depends on the sinking amount with respect to the center position of the levitation coil 11. For example, when the magnetic levitation train is full of passengers and travels at a relative speed of 500 km / h, and when the passenger is empty and travels at a relative speed of 300 km / h, there will be a large difference in the amount of current collected.
[0008]
Therefore, considering the minimum amount of electric power required for electrical equipment such as air conditioning, lighting, and refrigerators required for magnetic levitation trains, for example, as a design specification regarding current collection capacity per car, Even when traveling at a relative speed of 300 km / h, a current collecting capacity of 50 kW or more is required.
[0009]
FIG. 5 shows a schematic configuration of the current collecting coil device 6 viewed from the ground side of the carriage 1 shown in FIG. In order to achieve a current collecting capacity of 50 kW or more, it is necessary to attach the current collecting coil device 6 to the entire outer tub 2 as shown in FIG. Since the current collection capacity varies with the fourth power of the distance from the levitation coil 11 to the current collection coil 7, the current collection coil 7 is made as close to the levitation coil 11 as possible in order to increase the current collection quantity. is required.
[0010]
Further, the fluctuating magnetic field generated by the levitation coil 11 causes an eddy current on the surface of the outer tub 2, and the eddy current reduces the harmonic component of the magnetic field, thereby reducing the current collection capability. From the above, the current collecting coil 7 must be as close as possible to the floating coil 11 side and away from the surface of the superconducting magnet outer tub 2. By the way, the mounting position of the current collector coil device 6 is determined to be, for example, 80 mm from the center of the superconducting coil 5 to the surface of the current collector coil device 6 due to vehicle limitations and the like.
[0011]
In addition, when the magnetic levitation train is running, the current collecting coil 7 may be damaged by attraction of a magnetic material due to the strong magnetic field of the superconducting coil 5 or by a stepping stone caused by the wind pressure of the running, which may cause electrical ground insulation breakdown. There is sex. In particular, the impact energy applied to the current collecting coil 7 increases as a stepping stone or the like due to the wind pressure of the traveling becomes faster traveling. Therefore, it is conceivable to increase the mechanical strength by giving the surface member 9 a thickness. However, as the thickness of the surface member 9 increases, the distance between the current collecting coil 7 and the levitation coil 11 increases. Ability is reduced. For this reason, the current collecting coil device 6 has a problem that the surface of the ground coil side needs to be thin in order to enhance the current collecting ability, and the structure for improving the electrical ground insulation performance is required.
[0012]
The present invention has been made in view of the above, and an object of the present invention is to increase the current collecting ability and to sufficiently prevent damage to the current collecting coil conductor due to an impact object. It is to provide a current collector for trains.
[0013]
[Means for Solving the Problems]
That is, the present invention includes a current collecting coil disposed opposite to the ground coil and provided on the vehicle body, and a current collecting coil housing case housing the current collecting coil. In a magnetic levitation train current collector configured to collect current by inductive action, a buffer layer of an electrical insulator is provided between the current collecting coil and the inner wall surface of the current collecting coil storage case. It is intended to achieve the intended purpose.
[0014]
The present invention further includes a current collecting coil disposed opposite to the ground coil and provided on the vehicle body, and a current collecting coil housing case housing the current collecting coil. In a magnetic levitation train current collector configured to collect current by inductive action, it has good elongation characteristics and electrical insulation between the current collecting coil and the inner wall surface of the current collecting coil storage case. An object buffer layer is provided.

In a magnetic levitation train current collector configured to collect current by inductive action, it has good elongation characteristics and electrical insulation between the current collecting coil and the inner wall surface of the current collecting coil storage case. In addition to providing a buffer layer for the object, the current collecting coil is impregnated with resin under pressure and cured.
[0016]
The present invention further includes a current collecting coil disposed opposite to the ground coil and provided on the vehicle body, and a current collecting coil housing case housing the current collecting coil. In the magnetic levitation train current collector configured to collect current by inductive action, the current collector coil storage case is formed of glass fiber reinforced plastic, and the current collector coil and the current collector coil storage case The entire surface between the wall surfaces has good elongation characteristics and is provided with a buffer layer of an electrical insulator, and the current collecting coil and the storage case are impregnated with resin and cured.
[0017]
In this case, the buffer layer is made of a polyimide film, a Teflon sheet, or an olefin polymer.
[0018]
That is, since the magnetic levitation train current collector formed in this way is provided with a buffer layer of an electrical insulator between the current collecting coil and the inner wall surface of the current collecting coil storage case, The impact energy applied to the conductor of the current collector coil is buffered by the elongation of the buffer layer, and since the buffer layer is an electrical insulator, the thickness of the surface side of the current collector coil storage case can be reduced. Therefore, it is possible to improve the current collecting capability and sufficiently prevent damage to the current collecting coil conductor due to the impact object.
[0019]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in detail based on the illustrated embodiments. FIG. 1 shows in cross section the magnetic levitation train equipped with the current collector and the main parts of the current collector. 14 is a magnetic levitation train body, 13 is a ground side wall, 5 is a superconducting coil, 6 is a collecting coil device, 11 and 12 are ground coils, that is, 11 is a levitation coil, and 12 is a propulsion coil.
[0020]
The superconducting coil 5 for levitation propulsion is supported in the outer tub 2 via the inner tub 4 and the load support 3, and the magnetic field generated by the superconducting coil 5 is attached to the side wall 13 on the ground side. The levitation coil 11 and the propulsion coil 12 are attracted and repelled in the levitation direction and the propulsion direction, respectively, and the magnetic levitation train travels magnetically. As shown in FIG. 5, the current collecting coil device 6 is attached to the entire surface of the outer tub on the ground side of the surface of the outer tub 2. Of course, the opposite side of the carriage 1 has the same configuration.
[0021]
FIG. 1B shows an enlarged cross section of the current collecting coil device 6. As shown in this figure, the current collecting coil device 6 includes a current collecting coil 7 and this current collecting coil. 7, and the current collecting coil housing case 18 is composed of a surface member 9 and a back plate 10. That is, the current collecting coil 7 is accommodated in the surface member 9 processed so that the current collecting coil 7 is accommodated.
[0022]
In this case, a buffer material (buffer layer) 8 is provided between the current collecting coil 7 and the surface member 9. In other words, the buffer material 8 is laid on the concave portion of the surface member 9, and the current collecting coil 7 is disposed on the buffer material 8. And the back plate 10 is stuck on it.
[0023]
In this case, it is preferable that the current collecting coil device 6 is further impregnated with resin and cured by pressure. In this embodiment, the cushioning material 8 is provided on one side (the side close to the ground coil). However, this is not always necessary, and as shown in FIG. The buffer material 8 may be inserted between the plates 10. Of course, in this case as well, the current collecting coil device 6 may be hardened by pressure impregnation with resin. In this case, glass fiber reinforced plastic (GFRP) having mechanical strength is used as the surface member 9 and the back plate 10 for housing the current collecting coil 7.
[0024]
The buffer material 8 is preferably an electrically insulating material having elongation. For example, Kapton, Teflon, which is a polyimide material, ECO / light sheet, which is an olefin polymer, or the like is used. In particular, with this type of material, the thickness of the surface member 9 can be reduced, so that the current collection capability can be improved.
[0025]
As described above, in the case of the inductive current collector formed as described above, since the buffer material 8 is interposed between the current collecting coil 7 and the surface member 9, it is given to the current collecting coil 7. The impact energy is buffered by the elongation of the cushioning material 8, and since the cushioning material 8 is an electrical insulator and is stretched, the thickness of the surface member 9 can be reduced. Electric power can be improved.
[0026]
Further, in the case where a GFRP material is used for the surface member 9, when an object such as a metal object hits the surface member 9 with a considerable impact energy, the collision point is caused by brittle deformation of the GFRP and the current collecting coil together with the dent. In the wet environment, moisture may permeate into the defective part, and a ground fault may occur between the current collecting coil 7 and the ground. Due to the buffer material 8 having sufficient elongation, even if an impact object hits the current collecting coil device 6, the buffer material 8 is less likely to be perforated due to the effect of elongation of the buffer material 8, and an electrically insulating material is used. Therefore, there is an effect that a ground fault between the current collecting coil 7 and the ground hardly occurs.
[0027]
Further, as shown in FIG. 2, when a cushioning material 8 having an elongation that keeps an electrical insulating material is also inserted between the current collecting coil 7 and the back plate 10, an impact applied to the current collecting coil 7. There is an effect of further buffering energy.
[0028]
【The invention's effect】
As described above, according to the present invention, it is possible to improve the current collecting ability and to obtain a current collector for a magnetically levitated train that can sufficiently prevent damage to the current collecting coil due to an impact object. be able to.
