Abstract
Description
図6は、回転軸の軸方向に見た正面図である。電動機本体31の周囲にフレーム32が設けられ、このフレーム32に冷却器33が付設されている。電動機本体31とフレーム32と冷却器33は一体となって、外枠34とベース35とで形成される空間に入れられて全閉型の電動機が構成されている。冷却器33には、外部から給水管36及び排水管37が接続され、冷却水を通じることにより機内空気を冷却し、電動機本体31の温度を所定値以下に押さえるように構成されている(例えば、特許文献1参照)。
また、給・排水管36,37がベース35に貫通する部分は気密のためのシールが必要なため、組立が煩雑であることに加えて、給・排水管36,37との取合部が電動機本体31の四方に分散しているため、基礎のピット38内に敷設される配管の経路が複雑となり、敷設に手間が掛かるという問題点があった。
更に、回転電機本体と冷却器(熱交換器)が一体の外枠で覆われているので、回転電機が大形化すると、外枠の外形も大きくなるため、鉄道等による輸送が困難になるという問題点もあった。
以下、この発明の実施の形態1を図に基づいて説明する。図1は、回転電機の本体フレームと、熱交換器及び熱交換器カバー等の主要部を示す斜視図である。但し、回転子の図示は省略し、内部が見える状態を示している。図2は、回転電機の内部を模式的に示した平面断面図であり、中心の軸線から片側半分を示している。
なお、本願発明が対象とする回転電機は、回転軸が横方向に配置され、冷却媒体が密封され、水冷式熱交換器を備えた全閉横型回転電機であるが、以下の説明では、回転電機として同期発電機の場合を例に説明する。もちろん、電動機であっても良い。
発電機1は、本体フレーム2内に円筒形状をした固定子3が配置され、その内周側に、軸線6を中心に回転軸4と共に回転する回転子5がその軸線6を水平方向に向けて配置されている。
固定子3は、固定子鉄心3aが軸方向に所定の間隔で冷却ガス通路を設けた状態に積層され、固定子鉄心3aの内周面側に軸方向に形成した複数のスロットに固定子コイル3bが挿入されて構成されている。
一方、回転子5は、固定子3の内周面と所定のガス間隙が確保できる外径を有し、回転軸4と、磁極を形成する回転子鉄心5aと、回転子鉄心5aのスロットに挿入された回転子コイル(図示せず)とで構成され、本体フレーム2の両端の開口部を塞ぐエンドブラケット7の内周部に設けられた軸受8によって支承されている。
図1において、太矢印で示す方向、すなわち、回転子5の軸心である軸線6に直交する側面方向から本体フレーム2を見て、熱交換器11は、本体フレーム2の前面側の左右両端部近傍と、背面側の左右両端部近傍の各位置に、それぞれ1台ずつ合計4台が、縦方向に向けて配設されている。熱交換器11の詳細は後述するが、熱交換器11の本体部分の外面が本体フレーム2の内部に形成された冷媒流路中に曝された形となっている。熱交換器11の内部に冷却水を循環させることにより熱交換されて、冷媒ガス10が冷却される。このため、熱交換器11には、冷却水の出入り口となる給水口11bと排水口11cとが備わっている。
図1では、4台の熱交換器11のうちの、太矢印方向に見て、前方左の1台は、本体フレーム2から取り外された状態を示している。熱交換器11と、熱交換器カバー12と、当該熱交換器11に接続される給水管13a及び配水管14aとが解体された状態である。それらが組み立てられると、前方右の1台と同様になる。
本体フレーム2の、熱交換器11が取り付けられる位置には、熱交換器取付板15が設けられている。熱交換器取付板15には、冷媒流路を構成する開口部穴15bと熱交換器11を取り付けるためのねじ穴15aが設けられている。また、本体フレーム2の上面の一部を切り欠いてこの切欠部の周囲に設けた取付座16にも、ねじ穴16aが形成されている。図中に濃い網掛けで示す部分が熱交換器11の取付面となる部分である。
一方、本体フレーム2の側面には、熱交換器カバー12を取り付けるための大きな開口部2aが形成されており、開口部2aの周囲に設けカバー取付フランジ17には、熱交換器カバー12を取り付けるためのねじ穴17aが形成されている。図中に薄い網掛けで示す部分が熱交換器カバー12の取付面となる部分である。
熱交換器11の上部には、導入した冷却水を一旦貯める水室部11aが設けられており、内部は2分されて2室に分かれている。一方の室に連通して給水口11bが設けられ、他方の室に連通して排水口11cが設けられている。そして、水室部11aの下部には、複数の細管11dが、下部側の水室部を介して往復するように設けられて、給水側の水室と排水側の水室とが連絡されており、細管11dには多数のフィン11eが取り付けられている。
熱交換器11を本体フレーム2側に取り付けて固定するために、水室部11aの下部周囲に、取付穴11fを有する鍔状の取付フランジ11gが設けられ、更に、その下部側の熱交換器本体部を収納するフレームのうち、図で背面側のフレーム11hには、先に説明した本体フレーム2の熱交換器取付板15に形成したねじ穴15aに合致する取付穴11iが形成されている。
また、給水開始時や給水途中において、給水管内の空気や冷却水に混じった空気が、熱交換器11内に侵入するので、この空気を抜くためのベント管19が設けられている。
図5は、熱交換器カバー12を内側から見た斜視図である。全体が直方体の箱状をして、一面が全面開口し、その開口側の上面の一部は切り欠かれている。開口側の周囲には取付フランジ12aが設けられ、取付フランジ12aには取付穴12bが形成されている。また、上面の切欠部の周囲にもねじ穴12cを有する取付座12dが設けられている。下部側には、熱交換器11のドレン管18と対応させて、ドレン管用穴12eが開けられている。
図中に濃い網掛けで示す部分が熱交換器11の取付面となり、薄い網掛けで示す部分が本体フレーム2へ取り付ける取付面である。
図1の太矢印方向から見て前面左側の熱交換器部のように分解された状態から、先ず、熱交換器11を本体フレーム2の開口部2aから内部側へ挿入し、熱交換器11の取付フランジ11gを、本体フレーム2の上面側の取付座16に合わせ、同時に、熱交換器11のフレーム11hに形成した取付穴11iを本体フレーム2の内部の熱交換器取付板15に形成したねじ穴15aに合わせる。このとき、各接合面には気密を保つためにガスケット(図示せず)を挟み込んでいる。その状態で、外側からボルトをねじ穴にねじ込んで締め付けることにより熱交換器11が本体フレーム2に取り付けられる。
同様にして他の箇所にある熱交換器11及び熱交換器カバー12を全て取り付ける。
なお、ドレン管用穴12eとドレン管18との隙間は、図示しない閉塞板とシール材により気密に塞がれている。また、ドレン管18とベント管19は、組立完了後にドレン配管(図示せず)に接続される。
前面の左右両側の熱交換器11に接続される給・排水管13a,14a,13b,14bの形状は、逆J字状をしている。背面の左右両側の熱交換器に接続される給・排水管13c,14c,13d,14dの形状は、各給・排水口から立ち上がった後、軸線6の方向の中心側へ水平に伸び、次に90度折れ曲がって前面側へ水平に伸び、前面側で90度下方へ向けて折り曲がっている。なお、各給・排水管は、本体フレーム2に支持部材(図示せず)によって支持されている。
取付完了後は、各給・排水管と、基礎側のピット内に配管された給排水管(図示せず)との取合部20は、発電機1の前面下部側に並んだ形となっている。なお、取合部20を全て背面側としても良い。
第1点目は、熱交換器の給・排水口を、熱交換器の上方に配置して上出しとした点である。回転電機の熱交換器に給・排水する配水管は、回転電機の設置に先立ち、冷却水供給源(図示せず)から回転電機が設置される基礎面に設けられたピット内まで配管されており、回転電機を設置するとき、ピット内から立ち上がった給・排水管と、回転電機側の熱交換器に付属する給・排水管とが接続される。この接続点、すなわち取合部を予め決めておき、回転電機の製造メーカはその取合部までの配管を製作して納入し、現地において取合部で相手側の給・排水管と接続されるのが一般的である。
また、給・排水口を上出しにしたことにより、熱交換器カバー12を貫通して給・排水管を引き出す必要がないので、熱交換器カバー12の内外の貫通部はドレン管18の部分のみとなり、シール性の悪い円周面でのシール部が減り、作業が簡単になると共に、シール性を高めることができる。
分解可能な構造としたことにより、回転電機が大容量となり大型化した場合でも、輸送限界以内に納めることが可能になり、鉄道等によって輸送できる範囲が拡大される。
また、熱交換器カバーを貫通して給・排水管を引き出す必要がないので、貫通部のシール部が減り、作業が簡単になると共に、シール性を高めることができる。
