【００１１】
【発明が解決しようとする課題】
しかしながら、このような従来の６０度巻きによる変圧器コイルの巻回方法では、巻き始め角度は６０度であるが、巻き終わり角度が３０度であるため、占積率が悪い問題点があった。
【００１２】
本発明の目的は、占積率を向上させることができる６０度巻きによる変圧器コイルの巻回方法を提供することにある。
【００１３】
【課題を解決するための手段】
本発明は、最初はコイルの１ターン目、２ターン目及び３ターン目を該コイルの最下層に属するターンとして続けて巻き、次に前記１ターン目と前記２ターン目との間の上部溝及び前記２ターン目と前記３ターン目との間の上部溝にそれぞれ前記コイルの４ターン目 及び５ターン目を最下層から数えて２番目の層に属するターンとして続けて巻いた後、前記３ターン目の隣に前記コイルの６ターン目及び７ターン目を最下層に属するターンとして続けて巻き、次に前記３ターン目と６ターン目との間の上部溝に８ターン目を前記２番目の層に属するターンとして巻き、更に前記４ターン目と前記５ターン目との間の上部溝及び前記５ターン目と８ターン目との間の上部溝にそれぞれ９ターン目及び１０ターン目を前記コイルの最下層から数えて３番目の層に属するターンとして続けて巻き、次に前記６ターン目と７ターン目との間の上部溝に１１ターン目を前記２番目の層に属するターンとして巻いた後更に前記７ターン目の隣に１２ターン目及び１３ターン目を最下層に属するターンとして続けて巻き、次に前記７ターン目と１２ターン目との間の上部溝に１４ターン目を前記２番目の層に属するターンとして巻いた後更に前記８ターン目と前記１１ターン目との間の上部溝に１５ターン目を前記３番目の層に属するターンとして巻き、更に前記９ターン目と１０ターン目との間の上部溝及び前記１０ターン目と１５ターン目との間の上部溝にそれぞれ１６ターン目及び１７ターン目を最下層から数えて４番目の層に属するターンとして続けて巻き、次に前記１１ターン目と１４ターン目との間の上部溝に１８ターン目を前記３番目の層に属するターンとして巻き、更に前記１２ターン目と１３ターン目との間の上部溝に１９ターン目を前記２番目の層に属するターンとして巻いた後前記１３ターン目の隣に２０ターン目及び２１ターン目を最下層に属するターンとして続けて巻くという巻回の仕方で巻回作業を続けて、巻き始め角度が６０度となる６０度巻きによる俵積み巻回を巻回軸方向の一方の側から他方の側に順次行って変圧器コイルを形成する変圧器コイルの巻回方法を改良するものである。
【００１４】
本発明に係る変圧器コイルの巻回方法においては、コイルの最下層の最終ターンを巻く際には、２ターンを続けて巻くことなく、既に巻かれている最下層の幅方向の末端のターンの隣に該最下層の最終ターンを構成する１ターンのみを巻き、次に前記最下層の最終ターンと該最下層の最終ターンの一つ前のターンとの間の上部溝に１つのターンを前記最下層から数えて２番目の層に属するターンとして巻いた後、各層に既に巻かれている各層の幅方向の末端のターンに隣接させて１ターンを巻回する作業を各層で行ないながら、前記コイルの最下層から数えて３番目の層から最上層の一つ手前の層まで順次巻回作業を進め、
３番目の層から最上層の一つ手前の層まで順次巻回作業を進めた後、最上層では、既に巻かれている最上層の巻線の末端のターンに隣接させて続けて２ターンを隣り合わせに巻回し、次いで各層に既に巻かれている末端のターンに隣接させて１ターンを巻回する巻回作業を各層で行ないながら、最上層の一つ手前の層から前記３番目の層まで順次巻回作業を進め、その後、最下層から数えて４番目以降の上側の各層に対して既に巻回されている末端のターンに隣接させて１ターンを巻回する作業を順次行なう。
このように巻回すると、巻き始め角度のみならず、巻き終わり角度も６０度とすることができ、占積率を向上させることができる。また、同じターン数であれば、変圧器コイルを小型化できる。
【００１５】
【発明の実施の形態】
図１は、本発明に係る変圧器コイルの巻回方法における実施の形態の第１例を示したものである。
【００１６】
本例は、６０度巻きにより従来例と同様に６６ターンの変圧器高圧側コイルを巻回する方法の順序を示したものである。本例でも、５３ターン目までは従来の６０度巻きによる変圧器コイルの巻回方法と同じである。本例では、巻線１を下降させての最下層の幅方向の末端の最終ターンの巻回以降の巻回の仕方に特徴がある。
【００１７】
即ち、本例では、巻線１を下降させての最下層の幅方向の末端の最終ターンの巻回は、既に巻かれている最下層の幅方向の末端の４３ターン目の隣に、２回続けた巻回とせず、５４ターン目を１ターンのみ巻回する。
【００１８】
次に、上昇させて該最下層の幅方向の末端の最終ターンである５４ターン目とその隣の最下層の４３ターン目との間の上部溝に５５ターン目を最下層から数えて２番目の層に属するターンとして巻回し、次にそれより上の段の４４ターン目と５３ターン目の間の上部溝に５６ターン目を最下層から数えて３番目の層に属するターンとして巻回し、次にそれより上の段の４５ターン目と５２ターン目の間の上部溝に５７ターン目を最下層から数えて４番目の層に属するターンとして巻回し、次にそれより上の段の４６ターン目と５１ターン目の間の上部溝に５８ターン目を最下層から数えて５番目の層に属するターンとして巻回し、次にそれより上の段の４７ターン目と５０ターン目の間の上部溝に５９ターン目，５０ターン目と５８ターン目の間の上部溝に６０ターン目を最上層に属するターンとして続けて巻き、次に下降させて５１ターン目と５７ターン目の間の上部溝に６１ターン目を５番目の層に属するターンとして巻き、更に下降させて５２ターン目と５６ターン目の間の上部溝に６２ターン目を４番目の層に属するターンとして巻き、更に下降させて５３ターン目と５５ターン目の間の上部溝に６３ターン目を３番目の層に属するターンとして巻く。
【００１９】
次に、上昇させて５６ターン目と６３ターン目との間の上部溝に６４ターン目を４番目の層に属するターンとして巻回し、次にそれより上の段の５７ターン目と６２ターン目の間の上部溝に６５ターン目を５番目の層に属するターンとして巻回し、次にそれより上の段の５８ターン目と６１ターン目の間の上部溝に最終ターンである６６ターン目を最上層に属するターンとして巻く。
【００２０】
このように巻回すると、巻き始め角度のみならず、巻き終わり角度も６０度とすることができ、占積率を向上させることができる。
【００２１】
また、このような本発明による６０度巻きによる変圧器コイルの巻回方法によれば、同じターン数であれば、変圧器コイルを小型化できる利点がある。
【００２２】
全ターンが６６ターンである図１と図３とで比較した場合、図３に示す従来の６０度巻きによる変圧器コイルは１６ターン分の長さを持つのに対し、図１に示す本発明の６０度巻きによる変圧器コイルは１４ターン分の長さとなり、変圧器コイルを小型化できる。
【００２３】
図２は、本発明に係る変圧器コイルの巻回方法における実施の形態の第２例を示したものである。
【００２４】
本例は、最終ターン数を前述した６６ターンとせず、ターン数を増加させて変圧器高圧側コイルを巻回する方法の順序を示したものである。
【００２５】
本例では、６６ターン目に続けて、６１ターン目と６５ターン目の間の上部溝に６７ターン目を最上層に属するターンとして巻き、次に下降させて６２ターン目と６４ターン目の間の上部溝に６８ターン目を最下層から数えて５番目の層に属するターンとして巻き、次に上昇させて６５ターン目と６８ターン目の間の上部溝に最終ターンである６９ターン目を最上層に属するターンとして巻く。
【００２６】
このようにして巻回すると、巻き始め角度のみならず、巻き終わり角度も６０度となった断面台形状の変圧器コイルとなり、第１例より占積率を向上させることができる。
【００２７】
【発明の効果】
本発明に係る６０度巻きによる変圧器コイルの巻回方法においては、コイルの最下層の 最終ターンを巻く際には、２ターンを続けて巻くことなく、既に巻かれている最下層の幅方向の末端のターンの隣に該最下層の最終ターンを構成する１ターンのみを巻き、次に最下層の最終ターンと該最下層の最終ターンの一つ前のターンとの間の上部溝に１つのターンを最下層から数えて２番目の層に属するターンとして巻いた後、各層に既に巻かれている各層の幅方向の末端のターンに隣接させて１ターンを巻回する作業を各層で行ないながら、コイルの最下層から数えて３番目の層から最上層の一つ手前の層まで順次巻回作業を進め、３番目の層から最上層の一つ手前の層まで順次巻回作業を進めた後、最上層では、既に巻かれている最上層の巻線の末端のターンに隣接させて続けて２ターンを隣り合わせに巻回し、次いで各層に既に巻かれている末端のターンに隣接させて１ターンを巻回する巻回作業を各層で行ないながら、最上層の一つ手前の層から前記最下層から数えて３番目の層まで順次巻回作業を進め、その後、最下層から数えて４番目以降の上側の各層に対して既に巻回されている末端のターンに隣接させて１ターンを巻回する作業を順次行なうので、巻き始め角度のみならず、巻き終わり角度も６０度とすることができ、占積率を向上させることができる。
【００２８】
また、本発明による６０度巻きによる変圧器コイルの巻回方法によれば、同じターン数であれば、変圧器コイルを小型化できる利点がある。
