【発明の属する技術分野】
本発明は、導体を支持するための導体支持碍子に関する。
【０００２】
【従来の技術】
図１１は、従来の導体支持碍子を用いたスイッチギヤ内の主回路導体の支持方法（以下、従来例１と略称する）の実施状態を示す側面図である。図１１において、１１は絶縁性の導体支持碍子であり、導体支持碍子１１の上下端部には埋め金１２，１２がねじ加工されている。導体支持碍子１１の下端部は、ボルト１３の埋め金１２へのねじ止めにより支持フレーム１４に固定されている。また、スイッチギヤ内の主回路導体１５が、ボルト１６の埋め金１２へのねじ止めにより導体支持碍子１１に取り付けられている。
【０００３】
次に、スイッチギヤ内の主回路導体１５の支持方法の手順について説明する。導体支持碍子１１をボルト１３にて支持フレーム１４に取り付け、スイッチギヤ内に配置する主回路導体１５に導体支持碍子１１への取付け用の孔をあけ、直接導体支持碍子１１にボルト１６によって主回路導体１５を取付け配置する。
【０００４】
図１２は、従来の導体支持碍子を用いた主回路導体の他の支持方法（以下、従来例２と略称する）の実施状態を示す側面図である。図１２において、２１は絶縁性の導体支持碍子であり、導体支持碍子２１の上下端部には埋め金２２，２２がねじ加工されている。導体支持碍子２１の下端部は、埋め金２２を介して支持フレーム２３に固定されている。導体支持碍子２１の上端部には、Ｌ字状のサポート金具２４がボルト２５の埋め金２２へのねじ止めにより固定されている。また、スイッチギヤ内の主回路導体２６が、ボルト２７によりサポート金具２４に取り付けられている。
【０００５】
次に、スイッチギヤでの主回路導体２６の支持方法の手順について説明する。導体支持碍子２１を支持フレーム２３に取り付け、サポート金具２４をボルト２５にて導体支持碍子２１に取り付け、スイッチギヤ内に配置する主回路導体２６にサポート金具２４への取付け用の孔をあけ、サポート金具２４にボルト２７によって主回路導体２６を取付け配置する。
【０００６】
【発明が解決しようとする課題】
従来における主回路導体の支持方法は以上のようであるので、スイッチギヤ内の主回路導体１５，２６を支持する場合には、従来例１，２共に主回路導体１５，２６に固定用の孔を設ける必要があり、また、従来例２ではサポート金具２４で固定する必要がある。
【０００７】
また、従来例１，２共に導体支持碍子１１，２１に埋め金１２，２２を設ける必要があり、コストが高くなるだけでなく、絶縁導体である主回路導体１５，２６を支持する場合には、この埋め金１２，２２が中間電位になり、絶縁物の絶縁破壊につながり、絶縁性能を維持できなくなるという問題点がある。そこで、固定部のみ絶縁をなくして裸充電部と同電位にすることにより対応しているが、他相の主回路導体，接地金属との空間絶縁距離を縮小できないという問題点がある。
【０００８】
更に、従来例１では、支持フレーム１４に導体支持碍子１１を取り付ける場合に、支持フレーム１４の裏側からボルト１３にて固定する必要があり、その作業性が悪いという問題点がある。
【０００９】
本発明は斯かる事情に鑑みてなされたものであり、複数種類の導体を貫通支持できる態様の孔を設けておくことにより、埋め金をなくした構成とできてボルト，サポート金具等の固定用部材が不要であり、種々の種類の導体を簡便に支持できる導体支持碍子を提供することを目的とする。
【００１０】
本発明の他の目的は、胴部の形状を十字状にすることにより、使用する絶縁材料の量を低減でき、コスト低下を図れる導体支持碍子を提供することにある。
【００１１】
本発明の更に他の目的は、支持フレーム等の外部体への固定部の一部をＵ字状にスリット化することにより、組立作業の利便化を図れる導体支持碍子を提供することにある。
【００１２】
【課題を解決するための手段】
本発明に係る導体支持碍子は、導体を支持する頭部を備えており、該頭部は前記導体が貫通する孔を有しており、該孔の周縁は異なる形状の導体を貫通支持するように種々の径の円弧にて形成されており、前記円弧にて形成された前記周縁は互いに隣り合った凹部分からなることを特徴とする。
本発明に係る導体支持碍子は、外部体に固定される固定部が設けられており、該固定部の一部がＵ字形のにスリット状に形成されていることを特徴とする。
本発明に係る導体支持碍子は、複数の導体が貫通する孔を有して前記複数の導体を支持するように形成された頭部を備えており、前記孔は第１導体を支持するための第１支持部及び第２支持部が設けられた周縁を有しており、前記第１支持部及び第２支持部は前記第１導体の長手方向に厚さ部分を有しており、該厚さ部分は前記第１導体の実質的な長さに沿って前記第１導体と接触することを特徴とする。
本発明に係る導体支持碍子は、第１導体を支持するための第１支持部及び第２支持部、並びに、前記第１導体とは形状が異なる第２導体を支持するための第３支持部及び第４支持部が前記孔の周縁の異なる位置に設けられていることを特徴とする。
本発明に係る導体支持碍子は、前記孔は、板状の棒導体を支持するために、溝底部の断面が半円形であって前記棒導体の長手方向に延在する溝の形状を有することを特徴とする。
本発明に係る導体支持碍子は、前記第１支持部及び第３支持部、または、前記第２支持部及び第４支持部は、異なるパターンの曲線形状を有することを特徴とする。
【００１３】
本発明の導体支持碍子にあっては、１または複数の導体をその孔に貫通して支持する。よって、従来のようなボルト，サポート金具等の特殊な部材を使用することなく、簡便にスイッチギヤ内の導体を支持できる。また、導体支持碍子の埋め金をなくして空間絶縁距離を縮小することができ、絶縁した導体をそのまま保持できる。
本発明の導体支持碍子にあっては、その孔の形状を、複数種の導体に適合できるように設定しておく。よって、種々の導体を支持でき、スイッチギヤ内での導体の様々な配置が可能である。
本発明の導体支持碍子にあっては、強度を保つための胴部を断面十字形にしている。よって、円柱状にした場合に比べて、使用する絶縁材料を削減することが可能である。
本発明の導体支持碍子にあっては、外部体に固定される部分をＵ字状にスリット化している。よって、導体支持碍子側からの外部体への取付け作業が可能となり、作業効率を向上することが可能である。
【００２０】
【発明の実施の形態】
以下、本発明をその実施の形態を示す図面に基づいて具体的に説明する。
図１（ａ），（ｂ）は、本発明の導体支持碍子の正面図，側面図、図２（ａ），（ｂ）は、本発明の導体支持碍子の上面図，下面図である。
【００２１】
導体支持碍子１の上部（頭部）には、スイッチギヤ内の数種類の主回路導体を貫通支持するための孔１ａが形成されている。この孔１ａの周縁は、種々の径の円弧をつなぎ合わせた形状をなしており、１または複数の種々の形状の主回路導体を貫通させて支持できるようになっている。
【００２２】
また、導体支持碍子１の中央部（胴体部）には、強度を維持するための十字状の補強部材１ｂが設けられている。また、導体支持碍子１の下部（足部）は、後述する支持フレーム３への固定部であり、その固定部の４箇所にＵ字状のスリットが形成されていてねじ止め固定部１ｃとなっている。
【００２３】
なお、以上のような構成をなす導体支持碍子１は、エポキシ樹脂系・ガラス基材ポリエステル樹脂系の成形材料を用いて一体的に成形される。
【００２４】
次に、このような構成の導体支持碍子１を用いて、スイッチギヤ内の主回路導体を支持する方法について説明する。図３，図４は、主回路導体の支持方法の一例の実施状態を示す側面図，拡大正面図である。図３，図４に示す例では、水平方向に２枚の主回路導体２，２を、導体支持碍子１の孔１ａに貫通させて支持している。
【００２５】
また、図５，図６は、主回路導体の支持方法の他の例の実施状態を示す側面図，拡大正面図である。図５，図６に示す例では、垂直方向に１枚の主回路導体２を、導体支持碍子１の孔１ａに貫通させて支持している。
【００２６】
更に、図７〜図１０は、主回路導体の支持方法の更に他の例の実施状態を示す拡大正面図である。図７に示す例では、図３，図４に示す例と同じ幅の１枚の主回路導体２を水平方向に、導体支持碍子１の孔１ａに貫通させて支持している。図８に示す例では、図７に示す例より幅が狭い１枚の主回路導体２を水平方向に、導体支持碍子１の孔１ａに貫通させて支持している。図９に示す例では、図５，図６に示す例より幅が広い１枚の主回路導体２を垂直方向に、導体支持碍子１の孔１ａに貫通させて支持している。図１０に示す例では、図９に示す例と同じ幅の２枚の主回路導体２を垂直方向に、導体支持碍子１の孔１ａに貫通させて支持している。
【００２７】
このようにして、支持対象の主回路導体２の取付け方（水平取付け，垂直取付け）、大きさ（狭い，広い）、枚数（１枚，２枚）を、通電電流に応じて、使い分けすることが可能である。なお、上述した導体支持碍子１の孔１ａの形状、及び、主回路導体２の取付け例は一例であって、本発明がこれらに限定されるものでないことは言うまでもない。
【００２８】
次に、このような主回路導体２の支持手順について説明する。まず、導体支持碍子１のねじ止め固定部１ｃを介して、固定ボルト４により、導体支持碍子１を支持フレーム３に固定する（図３，図５参照）。この際、支持フレーム３側に溶接ナットまたはナットサート等を使用することにより、この固定作業を全て導体支持碍子１側から行うことができ、作業効率が良い。また、導体支持碍子１の支持フレーム３への取付け位置については、固定ボルト４をＵ字状スリットのねじ止め固定部１ｃ内で移動させて決定することができる。
【００２９】
そして、スイッチギヤ内に配置されている支持対象の１枚または複数枚の主回路導体２を、導体支持碍子１の孔１ａに貫通させて支持する。この際、孔１ａの周縁の弧状形状を利用して、ボルト，サポート金具等の固定部材を用いることなく、１枚または複数枚の主回路導体２を導体支持碍子１で支持できる。また、上述した支持例を含めて、その大きさ，形状，枚数を問わずに、種々の主回路導体２の導体支持碍子１への支持が可能である。
【００３０】
また、主回路導体２を支持する際にねじ固定を必要としないので、絶縁導体の主回路導体２を使用する場合では、絶縁した状態のままで主回路導体２を支持することが可能となり、他の主回路導体，周囲の接地金属との空間絶縁距離を従来例に比べて縮めることができる。
【００３１】
【発明の効果】
以上のように本発明の導体支持碍子では、支持対象の導体を貫通保持する孔を設けるようにしたので、従来のようなボルト，サポート金具等の特殊な部材を使用することなく、導体を簡便に支持することが可能である。また、導体支持碍子の埋め金を不要として空間絶縁距離を縮小することができ、絶縁した導体をそのまま保持できる。また、ボルト，サポート金具等の固定用部材が不要であって、部品の削減及び作業時間の短縮を図ることができ、更には、スイッチギヤの低コスト化につながる。
【００３２】
また、本発明の導体支持碍子では、形成する孔の形状を、複数種の導体に適合できるように設定しておくようにしたので、形状が異なる様々な種類の導体を支持でき、スイッチギヤ内での導体の様々な配置が可能である。
【００３３】
また、本発明の導体支持碍子では、強度を保持するための胴部断面の形状を十字状にするようにしたので、使用する絶縁材料の量を低減でき、コストの低減化を図ることが可能である。
【００３４】
更に、本発明の導体支持碍子では、支持フレーム等の外部体との固定部の一部をＵ字状にスリット化するようにしたので、従来のように支持フレームの裏側からでなく、導体支持碍子側から支持フレームへの取付け作業を行うことができ、作業効率を向上することが可能である。

Therefore, although only the fixed part is eliminated and the potential is made equal to that of the bare charged part, there is a problem that the space insulation distance from the main circuit conductor of the other phase and the ground metal cannot be reduced.
