Description
【0001】
【発明の属する技術分野】
本発明は、超電導磁気浮上式鉄道の停車駅区間の車両が低速乃至停止時における車両への給電システムに関するものである。
【0002】
【従来の技術】
従来、超電導磁気浮上式鉄道の車両への給電は、以下のようにして行われていた。
【0003】
図6は従来の超電導磁気浮上式鉄道の走行時における車両への給電システムを示す模式図、図7はその超電導磁気浮上式鉄道の停車駅区間における車両への給電システムを示す模式図である。
【0004】
これらの図において、1はガイドウェイ、2はそのガイドウェイ1の側壁、3はそのガイドウェイの側壁2の車両に対向する内側面に配置される推進コイル、4はその推進コイル3の表側に配置される浮上コイル、5はガイドウェイ1のベッド部に配置される集電レール、6は超電導磁気浮上式鉄道の車両、7はその車両6の両側に配置される超電導磁石、8はその超電導磁石7の外側に配置される集電コイル、9は超電導磁気浮上式鉄道の車両6の底部に出没可能な集電シュー、10は車輪である。
【0005】
このように、従来の超電導磁気浮上式鉄道においては、車両の走行区間では、浮上コイル4と集電コイル8間の磁界により、集電コイル8に誘導した電力を車両内の電力として給電するようにしている(例えば、本願特許出願人によって既に出願済の、特開2000−261902、特開2000−225939、特開2000−197213参照)。
【0006】
上記した車両の走行区間においては、走行に伴って生じる高調波磁界を利用するため、十分な誘導集電を行わせることができるが、停車駅区間では車両が低速乃至停止するため、当然誘導集電を行わせることができない。そこで、図7に示すように、停車駅区間ではガイドウェイ1のベッドに高電圧電源に接続される集電レール5を敷設するとともに、集電シュー9を操作装置(図示なし)によって車両6の底面からガイドウェイ1の集電レール5上へ降ろして、集電シュー9を集電レール5に摺動させて集電し、車両6内への電力の供給を行うようにしている。
【0007】
【発明が解決しようとする課題】
しかしながら、上記した従来の超電導磁気浮上式鉄道の停車駅区間における車両への給電システムでは、停車駅区間に高電圧電源に接続される集電レールを敷設し、集電シューを操作装置によって車両の底面から降ろして、その集電レールに摺動させて集電するように構成しているため、
(1)機械的な操作機構を有する集電シューが台車に必要となる。
【0008】
(2)集電シュー及び集電レールの摩耗があり、メンテナンス費用が嵩む。
【0009】
(3)誘導集電から接触集電への切り替えの時間ロスが生じる。
【0010】
(4)集電レールに高電圧が印加されるので感電の危険がある。
といった問題があった。
【0011】
本発明は、上記状況に鑑みて、構成が簡便で、メンテナンスおよび切り替えが円滑で安全性の高い超電導磁気浮上式鉄道の停車駅区間の車両が低速乃至停止時における車両への給電システムを提供することを目的とする。
【0012】
【課題を解決するための手段】
本発明は、上記目的を達成するために、超電導磁気浮上式鉄道の停車駅区間の車両が低速乃至停止時における車両への給電システムにおいて、超電導磁気浮上式鉄道の停車駅区間のガイドウェイの側壁の内側面に配置される推進コイルと、該推進コイルの表側に、上側にはU,V,W相のコイルが並列に配置され、下側には前記上側のU,V,W相のコイルと上下に対称的に−U,−V,−W相のコイルが並列に配置され、かつ前記推進コイルとは別個の系統として設けられる磁界発生コイルを配置し、車両の台車の側面には超電導磁石が搭載され、該超電導磁石の外側に集電コイルが取り付けられ、前記車両の走行区間においては、地上側の浮上コイルの磁界により前記集電コイルに誘導電圧が生成されて給電し、前記車両が前記停車駅区間に入ると、前記磁界発生コイルからの磁界を前記集電コイルで受けて給電する。
【0013】
【発明の実施の形態】
以下、本発明の実施の形態について詳細に説明する。
【0014】
図1は本発明の実施例を示す超電導磁気浮上式鉄道の停車駅区間における車両への給電システムの模式図、図2はその停車駅区間における車両と磁界発生装置との関係を示す上面模式図、図3はその停車駅区間における車両の超電導磁石と磁界発生コイルの配置を示す模式図である。この実施例の場合も、車両の走行区間は従来の図6と同じく誘導集電が行われるので、ここではその説明は省略する。また、図1における磁界発生コイル11以外の部分は、図7と同様であるので、それらの部分は同じ符号を付して説明を省略する。
【0015】
図1に示すように、超電導磁気浮上式鉄道の停車駅区間では、ガイドウェイ1の側壁2の車両6に対向する内側壁には磁界発生コイル11が付設されている。
【0016】
図2においては、車両21の両側には超電導磁石22を搭載し、その外側に集電コイル23を搭載している。一方、停車駅区間のガイドウェイ31の車両21に対向する内側壁32には磁界発生コイル33が付設されている。
【0017】
図4は本発明の実施例を示す磁界発生コイルの結線例を示す図、図5は本発明の実施例を示す誘導集電装置の構成を示す模式図である。
【0018】
図4において、41は3相インバータ、42は磁界発生コイルであり、この磁界発生コイル42は、上側にはU,V,W相のコイルが並列に配置され、また、下側には上側U,V,W相のコイルと上下に対称的に−U,−V,−W相のコイルが並列に配置される。
【0019】
一方、例えば、図5において、車両の台車51の側面には超電導磁石52が搭載され、その超電導磁石52の外側には集電コイル53が取り付けられる。そこで、車両の走行区間においては、地上側の浮上コイルの磁界により、集電コイル53に誘導電圧が生成され給電する。そして、車両が停車駅区間に入ると、上記した磁界発生コイル42と集電コイル53との間で誘導電圧を生成させる。その誘導電圧は集電コイル53に生成され、PWM(パルス幅変調)コンバータ54によって電力変換され、車両内の電力として利用される。
【0020】
このように構成したので、従来のように、高電圧が印加される集電レールや、機械的な操作機構を有する集電シューを設ける必要がないため、当然、集電シュー、集電レールの摩耗はなく、メンテナンス費用が嵩むこともない。また、誘導集電から接触集電への切り替えの時間ロスが生じることもないし、集電レールへの高電圧の印加による感電の危険もない。つまり、構成が簡便で、メンテナンスおよび切り替えが円滑で安全性の高い超電導磁気浮上式鉄道の停車駅区間における車両への給電を行うことができる。
【0021】
なお、本発明は上記実施例に限定されるものではなく、本発明の趣旨に基づいて種々の変形が可能であり、それらを本発明の範囲から排除するものではない。
【0022】
【発明の効果】
以上、詳細に説明したように、本発明によれば、以下のような効果を奏することができる。
【0023】
(A)車両の停車駅区間に至ると、自動的に磁界発生コイルによる磁界が集電コイルに作用して、誘導集電が行われることになり、構成が簡便で、メンテナンスが容易である。
【0024】
(B)車両が停車駅区間へ入ると誘導集電装置は瞬時に発電を開始でき、車両の停車駅区間での切り替えの時間的ロスがない。
【0025】
(C)誘導集電であるために感電の危険がなく安全性が高い。
