(第1の実施形態)
図1は、第1の実施形態に係る駆動制御装置10を鉄道車両8の床下に設置した状態を示し、図2は、駆動制御装置の全体概略構成を示すブロック図である。
図1および図2に示すように、駆動制御装置10は、鉄道車両8とレール7aとの間の車体床下に艤装され、鉄道車両の車輪7を駆動する複数台、例えば、4台の電動機12a~d(同じ種類の装置が複数存在する場合は、必要に応じてa、b、c、d、-------のようにサフィックスを付記するときがある)を駆動する駆動制御装置である。電動機12は、例えば、永久磁石同期電動機を用いている。駆動制御装置10は、それぞれ1つの電動機12に接続された4つの電力変換装置、例えば、インバータ(IV)14a~dと、各インバータと電動機12との間に接続された4つの接触器16と、インバータ14、接触器16及び電動機12を制御する制御装置18と、を備えている。
インバータ回路11は、U相、V相、W相の各ユニットを有している。U相ユニット11uは、直流電源19の直流正極端子Pと直流負極端子Nとの間に順次直列に接続された第1、第2スイッチング素子21u、22uを有している。同様に、V相ユニット11vは、直流正極端子Pと直流負極端子Nとの間に順次直列に接続された第1、第2スイッチング素子21v、22vを有し、W相ユニット11wは、直流正極端子Pと直流負極端子Nとの間に順次直列に接続された第1、第2スイッチング素子21w、22wを有している。これら複数の半導体スイッチング素子は、例えば、IGBT(insulated gate bipolar transistor)やGTO等の自己消弧型半導体素子からなり、例えば、IGBTと、このIGBTに逆並列に接続されたダイオードとがモジュール化されている。各スイッチング素子内のダイオードやIGBTは、例えば、Siや低損失半導体素子である窒化ケイ素(SiC)素子により形成されている。
(装置の全体構造)
次に、駆動制御装置10の全体の構成を詳細に説明する。
図4および図5は、駆動制御装置10の外観を示す斜視図、図6は、筐体の装置カバーを取り外して駆動制御装置の内部構造を示す斜視図、図7は、筐体の装置カバーを取り外して駆動制御装置の内部構造を示す側面図である。
各装置カバー70は、周縁部が筐体60側に折り曲げられた矩形板により形成され、例えば、各装置カバー70の上端部が2つ、あるいは、3つのヒンジ部72により、回動自在に側壁65a、あるいは、側壁65bに支持されている。これにより、装置カバー70は、側壁の開口を覆い、側壁の一部を構成する閉じ位置と、開口を開放する開放位置との間を回動することができる。各装置カバー70の底壁63側には、装置カバーを閉じ位置にロックするロックレバー71が設けられている。更に、装置カバー70の中央部分には、装置カバーを開閉および脱着する際に用いる取っ手73が取り付けられている。
図6、図7、図9乃至図11に示すように、筐体60は、装置カバー70の不用意な脱落を防止するストッパ76を有している。ここでは、ストッパ76は、本体フレーム61に形成され装置カバー70側に突出した板金により形成されている。ストッパ76は、閉じ位置に閉じられた装置カバー70がヒンジ部72の抜け方向に移動した際に装置カバーに係合し、装置カバーの抜け方向の移動を規制する。これにより、装置カバー70の不用意な脱落を確実に防止することができる。なお、装置カバー70を開放位置側に回動することにより、ストッパ76は装置カバー70と係合不能となり、装置カバー70を筐体60から取り外すことができる。
図5乃至図6に示すように、駆動制御装置10は、筐体60に装着され、その一部が第1収容部66a内に配置されたパワーユニット68を備えている。パワーユニット68は、側壁65bの開口を通して、筐体60内に脱着可能に挿入され、筐体60に固定されている。その脱着方向Aは、筐体60の幅方向、側壁65aと直交する方向となっている。
パワーユニット68は、放熱フィン86を保護するため放熱フィン86を覆うような形状のフィンカバー88を備えている。このフィンカバー88は、矩形状の前面部88aと、前面部88aの両端部に接続される2つの矩形状の側面部88bによって、ほぼU字形状に形成されている。前面部88aは、放熱フィン86が冷却ブロック87と接している端部とは反対側の端部、つまり、放熱フィンの86の延出端側に位置し、側面部88bは、放熱フィン86の走行風の流入側および流出側に位置している。このフィンカバー88は、ベースフレーム78の矩形枠85aにボルト等によって固定される。また、フィンカバー88は、鉄道車両8側およびレール7a側において、放熱フィン86を覆うことなく開口部を有している。
次に、冷却ブロック87上の半導体素子と接続される2枚の第1制御基板82について説明する。図14、図15および図17に示すように、2枚の第1制御基板82は、冷却ブロック87の受熱面84bとほぼ平行に対向するように車両8側とレール7a側の上下に配置されベースフレーム78に取り付けられている。各第1制御基板82は、例えば、ゲートアンプ基板であり、各インバータ14の半導体素子に接続され、スイッチング信号を出力する。第1制御基板82の裏面及び外周側に第1コネクタ81が設けられている。
前述の第1コネクタ81に接続する第2コネクタ83を有する2つの第2制御基板84について説明する。第2制御基板84は、例えば、ゲートアンプ基板に制御信号を出力するゲート制御基板である。図14に示すように、パワーユニット68は2枚の第2制御基板84を有し、これらの第2制御基板84はベースフレーム78の2つの支持枠85bにそれぞれ摺動自在に取り付けられている。より詳細には、図14乃至図19に示すように、第2制御基板84は、この第2制御基板84よりも一回り大きい矩形状の支持基板(支持板金)94上に絶縁層95を介して取り付けられている。また、図15、図16に示すように第2制御基板84を覆うメッシュ状のカバー96が支持基板94に取り付けられている。更に、支持基板94の一端部は第2制御基板84側に直角に折曲げられ、この折曲げ部に取手97が取り付けられている。第2制御基板84の取手97と反対側の端部に第2コネクタ83が設けられている。
また、図14、図15、図18、図19、図20、図21に示すようにパワーユニット68は、コネクタ支持フレーム100と出力コネクタ104u1~104w4を備えている。コネクタ支持フレーム100は、パワーユニット68の脱着方向Aと直交する方向(冷却器80の受熱面84と平行な方向)に延びる細長いコネクタ支持フレームである。出力コネクタ104u1~104w4は、コネクタ支持フレーム100にエポキシ等の絶縁板102を挟んで取り付けられている。コネクタ支持フレーム100および出力コネクタは、パワーユニット68の上部に、すなわち、筐体60の天井壁62の近傍に設けられている。図20に示すように、出力コネクタは、4つのインバータ14のU、V、Wの出力にそれぞれ接続された、3つの出力コネクタ104u1、v1、w1、3つの出力コネクタ104u2、v2、w2、3つの出力コネクタ104u3、v3、w3、および3つの出力コネクタ104u4、v4、w4を含んでいる。これらの出力コネクタ104u1乃至104w4は、コネクタ支持フレーム100の長手方向に沿って一列に並んで、かつ、互いに隙間をおいて、配置されている。
また、図20及び図21に示すように、コネクタ支持フレーム100の出力コネクタ104u1~104w4間には、複数の位置決めピン106が立設され、コネクタ支持フレームからパワーユニット68の脱着方向Aに延びている。位置決めピン106は、出力コネクタ列の端部およびもう一方の端部、出力コネクタ104w1、104u2の間、出力コネクタ104w3、104u4の間にそれぞれ設けられている。
図14、図15に示すように、パワーユニット68は、インバータ14へ電流を流すための直流正極端子Pと直流負極端子Nを構成するPN入力端子108を備えている。このPN入力端子108は、パワーユニット68の下部に、すなわち、筐体60の底壁63傍に設けられている。PN入力端子108は、図22、図23に示すように、板状の正極端子110aと、この正極端子とほぼ同一の大きさに形成された板状の負極端子110bと、を有し、これら正極端子110aおよび負極端子110bは、絶縁層112を挟んで互いに重ね合わされ、互いに同一方向に沿って延在している。例えば、エポキシ等により形成された絶縁層112は、正極端子110aおよび負極端子110bよりも大きな面積を有し、正極端子110aおよび負極端子110bの外周部から所定幅だけ外側に延出している。PN入力端子108は、例えば、ベースフレーム78に取付けられ、このベースフレームから第1制御基板82を超えて脱着方向Aに延出している。そして、PN入力端子108は、筐体60の底壁63とほぼ平行に延びている。
次に、前述したPN入力端子108との接合部を有するフィルタコンデンサ26、27について説明する。図6に示すように筐体60の第1収納部66aにおいて、インバータ14を構成する複数のフィルタコンデンサ26、27が底壁63上に設置されている。図24に示すように、これらのフィルタコンデンサ26、27は、パワーユニット68のPN入力端子108に接合可能な接続端子122を有している。フィルタコンデンサ26、27は、パワーユニット68を筐体60に装着した際、2枚の第2制御基板84の間に位置するように配置されている。また、フィルタコンデンサ26、27は、後述する高圧側コネクタを介して、電源に接続される。
図24に示すようにパワーユニット68は、筐体60の側壁開口から筐体60の第1収納部66aに挿入および装着される。図26乃至図28に示すように、上記装着の際はパワーユニット68側の位置決めピン106が、筐体60側のコネクタ支持フレーム124の位置決め孔128にそれぞれ挿入される。位置決めピン106と位置決め孔128が接合することで、パワーユニット68側の出力コネクタ104u1乃至104w4に対してそれぞれ筐体側の入力コネクタ126u1乃至126w4が対向するように位置づけられる。そして、位置決めピン106と位置決め孔128のガイドに従い、パワーユニット68を筐体60の所定位置まで更に押込むことにより、パワーユニット68側の出力コネクタ104u1乃至104w4が筐体60側の入力コネクタ126u1乃至126w4にそれぞれ嵌合する。また同時に、パワーユニット68のPN入力端子108が、フィルタコンデンサ26、27の接続端子122に係合し、導通する。これにより、パワーユニット68に設けられたインバータ14がそれぞれ対応する接触器16に接続されるとともに、フィルタコンデンサ26、27を介して電源19に接続される(パンタグラフ、ヒューズ、スイッチを介して電源に接続される)。
図5乃至図7、図27に示すように、筐体60に装着されたパワーユニット68は、矩形枠85aを筐体60の側壁65bおよび本体フレーム61に固定することにより、所定位置に配置される。パワーユニット68の放熱フィン86およびフィンカバー88は、筐体60の外側に突出して位置し、車両の走行風を受けることができる。パワーユニット68の他の部分は、筐体60の第1収納部66a内に配置される。この際、パワーユニット68に取付けられた2枚の第2制御基板84は、フィルタコンデンサ26、27の両側に並んで位置し、フィルタコンデンサと本体フレーム61との比較的狭いスペースに効率良く配置される。また、各第2制御基板64の延出端側は、筐体60の反対側の側壁65aの近傍に位置している。そのため、装置カバー70を取外すことにより、側壁65aの開口側から第2制御基板64を点検、保守することができるとともに、パワーユニット68に対して第2制御基板64を抜き差しすることができる。
図4、図6、図29に示すように、筐体60の側壁65aの外面、鉄道車両8側に複数、例えば、4つの高圧側コネクタ(連結コネクタ)134a、134b、134c、134d、および複数、例えば、3つの高圧側コネクタ(連結コネクタ)136a、136b、136cが取付けられている。高圧側コネクタ134a、134b、134c、134dは、筐体60を貫通し、第1収納部66aに対向して設けられ、筐体60内に配置された配線138により、4つの接触器16の出力に直接、接続されている。高圧側コネクタ134a、134b、134c、134dは、例えば、ねじ込み式のコネクタであり、これらの高圧側コネクタの外側から、モータ12に接続された連結コネクタ140が接続され、固定される。
図6および図30に示すように、制御装置18は、筐体60の第2収納部66bに収納された種々の機器を備えている。また、制御装置18は、複数、例えば、3つの接地コンデンサ141を備え、これらの接地コンデンサ141は、第2収納部66b内で天井壁62の内面側に設置されている。接地コンデンサ141は、ノイズ発生源となり易いことから、天井壁62に設置し、高圧線、モータフレームアース線、パワーユニットのアース線等が他の高圧、低圧線と並行にとならないように配置している。これにより、制御装置18に対する接地コンデンサ141からのノイズの影響を最小限とすることができる。
図6、図7、図26に示すように、4台の接触器16は、筐体60の第3収納部66c内に設置されている。接触器16は2台ずつ、側壁65a側と側壁65b側に配置され、側壁65a側および側壁65b側では筐体60の上下方向(車両8からレール7a方向)に並べて配置されている。このように、4台の接触器を幅方向および高さ方向に並べて配置することにより、小さな設置スペースに効率よく接触器を収納することができ、これにより、筐体60の小型化を図ることが可能となる。
図31は、第2の実施形態に係る駆動制御装置を概略的に示す断面図である。第2の実施形態によれば、駆動制御装置10の筐体60は、パワーユニットのPN入力端子とフィルタコンデンサの接続端子との接続部の像を筐体の外方に向けて反射する反射板150を備えている。反射板150の表面は、例えば、鏡面に形成されている。反射板150は、例えば、筐体60の天井壁62の内面に固定されている。反射板150の鏡面は、天井壁62に対して斜めに傾斜し、上記接続部に向いている。また、天井壁62には、反射板150で反射された像が透光する覗き窓152が形成されている。これにより、筐体60の外側から覗き窓152を通して上記接続部の接続状態を視認することができ、外側から点検し難い奥まった部位を容易に点検することが可能となる。
第2の実施形態において、駆動制御装置10の他の構成は、前述した第1の実施形態と同一である。
図32は、第3の実施形態に係る駆動制御装置を概略的に示している。本実施形態によれば、駆動制御装置10用の筐体60は、インバータおよびパワーユニットを収納する第1収納部および制御装置を収納した第2収納部を有する第1筐体60aと、接触器を収納した第3収納部を有する第2筐体60bとに分離されている。これにより、駆動制御装置10の接触器16を他の場所に独立して設置することができ、駆動制御装置10の設置場所の自由度を高めることができる。
図33は、第4の実施形態に係る駆動制御装置10の構成を概略的に示すブロック図である。この図に示すように、第4の実施形態によれば、駆動制御装置10は、4台の永久磁石動機電動機12にそれぞれ接続される4つのインバータ14と、これら4つのインバータ14の入力側と電源19との間に並列に接続された1台の接触器16と、インバータ14、接触器16および電動機12を制御する制御装置18と、を備えている。駆動制御装置10の他の構成は、前述した第1の実施形態と同一である。
以上のように構成された第2乃至第4の実施形態においても、大型化を抑制し製造コストの低減を図ることが可能な駆動制御装置を提供することができる。
