Description

【０００１】
【発明の属する技術分野】
この発明は、電力を受配電する金属閉鎖形スイッチギヤに関し、特にその盤寸法及び盤配置に関するものである。
【０００２】
【従来の技術】
図９は各種受電方式のうち、一回線受電方式のスケルトンの一例を示す回路図である。一回線受電方式のスケルトンは、受電部１、電力会社より供与され受電部１に接続された電力需給用計器用変成器（以下、ＶＣＴと略称する。）、計器用変圧器３、避雷器４及び複数のフィーダ部５により構成されている。
【０００３】
受電部１は、遮断器６、この遮断器６の両側に直列に接続された一対の断路器７、複数の接地開閉器８及び計器用変流器９を有している。フィーダ部５は、断路器１０、接地開閉器１１、遮断器１２及び計器用変流器１３を有している。
【０００４】
図１０は図９のスケルトンを従来の特高金属閉鎖形スイッチギヤを用いて構成した例を示すブロックスケルトン図（平面構成図）、図１１は図１０の特高金属閉鎖形スイッチギヤの外観を示す斜視図である。受電部１は受電盤１４に収容され、ＶＣＴ２はＶＣＴ盤１５に収容されている。計器用変圧器３及び避雷器４は、計器用変圧器・避雷器盤１６に収容されている。各フィーダ部５は、フィーダ盤１７にそれぞれ収容されている。
【０００５】
受電盤１４、ＶＣＴ盤１５、計器用変圧器・避雷器盤１６及びフィーダ盤１７は、横１列に並べて設置されている。各盤１４〜１７の奥行寸法及び高さ寸法は、内部の機器構成の最大寸法であるＶＣＴ盤１５の奥行寸法及び高さ寸法に合わせて互いに同じに揃えられている。但し、各盤の幅寸法は、それぞれの内部の機器構成の幅寸法に合わせて構成されている。
【０００６】
【発明が解決しようとする課題】
上記のように構成された従来の特高金属閉鎖形スイッチギヤにおいては、受電盤１４、計器用変圧器・避雷器盤１６及びフィーダ盤１７の奥行寸法や高さ寸法が、最大のＶＣＴ盤１５に合わせて決められているため、装置全体が大形化しコストアップの原因となっている。また、据付搬入においては、盤１４〜１７の高さが高いため、一般のエレベータには入らず、クレーンなどの設備が必要となり、これもコストアップの原因となっている。さらに、各盤１４〜１７は、奥行寸法を合わせて一列に列盤されているため、配置の自由度が小さく、電気室の形状によっては、配置が困難になってしまう。
【０００７】
この発明は、上記のような問題点を解決することを課題としてなされたものであり、全体を小形化して製品コストの削減を図ることができるとともに、配置に柔軟性を持たせることができる金属閉鎖形スイッチギヤを得ることを目的とする。
【０００８】
【課題を解決するための手段】
この発明に係る金属閉鎖形スイッチギヤは、受電盤、フィーダ盤及び電力需給用計器用変成器盤が並べて配置され、受電盤及びフィーダ盤の少なくともいずれか１つと、電力需給用計器用変成器盤とを接続するための接続導体を有するものにおいて、少なくとも受電盤、フィーダ盤及び計器用変圧器・避雷器盤のいずれかを含む複数の盤のうちの少なくとも一部の盤の奥行寸法が、電力需給用計器用変成器盤の奥行寸法の１／２以下になっており、全ての盤のうちの少なくとも一部の盤が互いに背面合わせの状態で配置されており、電力需給用計器用変成器盤に収容された電力需給用計器用変成器の導体の接続位置が、受電盤及びフィーダ盤の少なくともいずれか１つの導体の接続位置となるように接続導体によって変換されているものである。
【０００９】
また、この発明に係る金属閉鎖形スイッチギヤは、背面合わせで配置された盤内の機器を、その盤の前面からメンテナンス可能に構成したものである。
【００１０】
さらに、この発明に係る金属閉鎖形スイッチギヤは、電力需給用計器用変成器盤の両側に、接続導体を収容したＶＣＴ接続盤をそれぞれ配置したものである。
【００１１】
さらにまた、この発明に係る金属閉鎖形スイッチギヤは、計器用変圧器・避雷器盤、２台のフィーダ盤、及び計器用変圧器・避雷器盤と一方のフィーダ盤とを接続する母線変換盤を備え、計器用変圧器・避雷器盤、フィーダ盤及び母線変換盤の奥行寸法をそれぞれ電力需給用計器用変成器盤の奥行寸法の１／２以下とし、一方のＶＣＴ接続盤の隣に、計器用変圧器・避雷器盤と母線変換盤とを互いに背面合わせの状態で配置し、さらにその隣に２台のフィーダ盤を互いに背面合わせの状態で配置したものである。
【００１２】
また、この発明に係る金属閉鎖形スイッチギヤは、計器用変圧器・避雷器盤、２台のフィーダ盤、及び計器用変圧器・避雷器盤と一方のフィーダ盤とを接続する母線変換盤を備え、計器用変圧器・避雷器盤、フィーダ盤及び母線変換盤の奥行寸法をそれぞれ電力需給用計器用変成器盤の奥行寸法の１／２以下とし、受電盤及び母線変換盤をＶＣＴ接続盤と背面合わせの状態で配置し、受電盤及び母線変換盤の間に、計器用変圧器・避雷器盤及び２台のフィーダ盤を電力需給用計器用変成器盤と背面合わせの状態で配置したものである。
【００１３】
さらに、この発明に係る金属閉鎖形スイッチギヤは、受電盤、フィーダ盤及び計器用変圧器・避雷器盤の高さ寸法を１９００ｍｍ以下とし、電力需給用計器用変成器盤の筐体を、高さ寸法１９００ｍｍ以下の複数の分割筐体に分割可能としたものである。
【００１４】
【発明の実施の形態】
以下、この発明の実施の形態を図について説明する。
実施の形態１．
図１はこの発明の実施の形態１による特高金属閉鎖形スイッチギヤを示す一回線受電方式のブロックスケルトン図（平面構成）、図２は図１の特高金属閉鎖形スイッチギヤの外観を示す斜視図である。
【００１５】
図において、ＶＣＴ２を収容したＶＣＴ盤１５の両側には、ＶＣＴ接続盤２１が配置されている。ＶＣＴ接続盤２１には、接続導体２２が収容されている。一方のＶＣＴ接続盤２１の隣には、受電部１を収容した受電盤２３が配置されている。
【００１６】
他方のＶＣＴ接続盤２１の隣には、計器用変圧器３及び避雷器４を収容した計器用変圧器・避雷器盤２４と、接続母線２５を収容した母線変換盤２６とが配置されている。計器用変圧器・避雷器盤２４及び母線変換盤２６の隣には、それぞれフィーダ部５を収容した２台のフィーダ盤２７が配置されている。
【００１７】
また、図３に示すように、ＶＣＴ盤１５の奥行寸法Ｂに対して、図４に示すように、計器用変圧器・避雷器盤２４、母線変換盤２６及びフィーダ盤２７の奥行き寸法は、半分（１／２・Ｂ）となっている。さらに、ＶＣＴ接続盤２１の高さは、ＶＣＴ盤１５と同じであるが、計器用変圧器・避雷器盤２４、母線変換盤２６及びフィーダ盤２７の高さ寸法は、ＶＣＴ盤１５よりも小さくなっている。
【００１８】
計器用変圧器・避雷器盤２４と母線変換盤２６とは、互いに背面合わせに配置され、２台のフィーダ盤２７についても、互いに背面合わせに配置されている。受電部１、計器用変圧器・避雷器盤２４の内部機器及びフィーダ部５は、図９と同様の回路構成であるが、装置としては従来よりも小形化されており、また盤の前面側からメンテナンス可能に構成されている。
【００１９】
このような特高金属閉鎖形スイッチギヤでは、受電盤２３、フィーダ盤２７、計器用変圧器・避雷器盤２４及び母線変換盤２６などを背面合わせに列盤配置し、ＶＣＴ接続盤２１を介して、奥行寸法の大きいＶＣＴ盤１５の側方に配置したので、効率良くコンパクトに列盤配置することができ、全体を小形化して製品コストの削減を図ることができる。また、受電盤２３、フィーダ盤２７及び計器用変圧器・避雷器盤２４などが、背面合わせの２列配置となっていることにより、母線の構成の自由度が増し、配置に柔軟性を持たせることができる。
【００２０】
ここで、実施の形態１のような背面合わせの配置とすると、スイッチギヤの前後両側に盤の扉を開くためのスペースを確保する必要があるが、従来のスイッチギヤでも背面側にはメンテナンススペースを確保する必要があったので、この点で設置場所についての新たな制約を受けることはない。
【００２１】
実施の形態２．
次に、図５はこの発明の実施の形態２による特高金属閉鎖形スイッチギヤを示す一回線受電方式のブロックスケルトン図、図６は図５の特高金属閉鎖形スイッチギヤの外観を示す斜視図である。
【００２２】
この例では、受電盤２３及び母線変換盤２６がそれぞれＶＣＴ接続盤２１と背面合わせの状態で配置され、受電盤２３及び母線変換盤２６の間で、計器用変圧器・避雷器盤２４及び２台のフィーダ盤２７がＶＣＴ盤１５と背面合わせの状態で配置されている。
【００２３】
このような特高金属閉鎖形スイッチギヤでは、受電盤２３、フィーダ盤２７、計器用変圧器・避雷器盤２４及び母線変換盤２６などを、幅寸法の大きいＶＣＴ盤１５と、背面合わせにして列盤配置し、ＶＣＴ接続盤２１を介して接続したので、効率良くコンパクトに列盤配置することができ、全体を小形化して製品コストの削減を図ることができる。また、受電盤２３、フィーダ盤２７及び計器用変圧器・避雷器盤２４などが、ＶＣＴ盤１５と背面合わせの２列配置となっているので、母線の構成の自由度が増し、配置に柔軟性を持たせることができる。
【００２４】
なお、実施の形態１、２では、ＶＣＴ盤１５とＶＣＴ接続盤２１とを別の盤として構成したが、ＶＣＴ盤１５及びＶＣＴ接続盤２１を一面構成としてもよい。
【００２５】
また、実施の形態１、２では、受電盤２３、フィーダ盤２７、計器用変圧器・避雷器盤２４及び母線変換盤２６の盤の高さをＶＣＴ盤１５及びＶＣＴ接続盤２１の盤の高さより低くしていたが、同じ高さとしてもよい。
【００２６】
さらに、実施の形態１、２では、受電盤２３、フィーダ盤２７、計器用変圧器・避雷器盤２４及び母線変換盤２６の全てについて、奥行き寸法をＶＣＴ盤１５の１／２としたが、必ずしも全てでなくてもよく、一部の盤のみ小形化してもよい。また、奥行き寸法は、ＶＣＴ盤１５の１／２より小さくてもよい。
【００２７】
実施の形態３．
次に、図７はこの発明の実施の形態３による特高金属閉鎖形スイッチギヤに用いられる受電盤、フィーダ盤、計器用変圧器・避雷器盤又は母線変換盤を示す斜視図、図８は図７の特高金属閉鎖形スイッチギヤに用いられるＶＣＴ盤の筐体の分割・組立状態を示す説明図である。
【００２８】
この例では、受電盤２３、フィーダ盤２７、計器用変圧器・避雷器盤２４及び母線変換盤２６の高さ寸法ｈが１９００ｍｍ以下に設定されている。また、ＶＣＴ盤１５の筐体が２個の分割筐体３１，３２と２枚の扉３３ａ，３３ｂとに分割可能に構成されている。そして、分割筐体３１，３２の高さ寸法Ｈ１，Ｈ２もそれぞれ１９００ｍｍ以下に設定されている。
【００２９】
ＶＣＴ盤１５内のＶＣＴ２（図１）は、電力会社より供与されるものであり、実施の形態１と同様である。また、実施の形態１又は２のようなＶＣＴ接続盤２１を用いる場合には、その高さ寸法を１９００ｍｍ以下とするか、又は高さ寸法を１９００ｍｍ以下の分割筐体に分割可能とする。
【００３０】
このような特高金属閉鎖形スイッチギヤでは、受電盤２３、フィーダ盤２７、計器用変圧器・避雷器盤２４及び母線変換盤２６などの高さ寸法ｈを１９００ｍｍ以下とし、ＶＣＴ盤１５やＶＣＴ接続盤２１は、高さ方向で１９００ｍｍ以下に分割できる構造としたので、据付搬入時に、一般のエレベータを用いることができ、クレーンなどの設備が不要となり、コストダウンを図ることができる。
【００３１】
なお、実施の形態３では、ＶＣＴ盤１５の筐体を２分割したが、３個以上の分割筐体に分割することも可能である。
【００３２】
【発明の効果】
以上説明したように、この発明の金属閉鎖形スイッチギヤは、少なくとも受電盤及びフィーダ盤のいずれかを含む複数の盤のうちの少なくとも一部の盤の奥行寸法を、電力需給用計器用変成器盤の奥行寸法の１／２以下とし、全ての盤のうちの少なくとも一部の盤を互いに背面合わせの状態で配置したので、全体を小形化して製品コストの削減を図ることができるとともに、配置に柔軟性を持たせることができる。
【００３３】
また、この発明の金属閉鎖形スイッチギヤは、背面合わせで配置された盤内の機器を、その盤の前面からメンテナンス可能に構成したので、メンテナンス作業を容易に行うことができる。
【００３４】
さらに、この発明の金属閉鎖形スイッチギヤは、電力需給用計器用変成器盤の両側に、電力需給用計器用変成器盤と受電盤及び計器用変圧器・避雷器盤とを接続するための接続導体を収容したＶＣＴ接続盤をそれぞれ配置したので、盤の配置に柔軟性を持たせることができる。
【００３５】
さらにまた、この発明の金属閉鎖形スイッチギヤは、計器用変圧器・避雷器盤、２台のフィーダ盤、及び計器用変圧器・避雷器盤と一方のフィーダ盤とを接続する母線変換盤を備え、計器用変圧器・避雷器盤、フィーダ盤及び母線変換盤の奥行寸法をそれぞれ電力需給用計器用変成器盤の奥行寸法の１／２以下とし、一方のＶＣＴ接続盤の隣に、計器用変圧器・避雷器盤と母線変換盤とを互いに背面合わせの状態で配置し、さらにその隣に２台のフィーダ盤を互いに背面合わせの状態で配置したので、各盤を効率良く配置し、全体を小形化することができる。
【００３６】
また、この発明の金属閉鎖形スイッチギヤは、計器用変圧器・避雷器盤、２台のフィーダ盤、及び計器用変圧器・避雷器盤と一方のフィーダ盤とを接続する母線変換盤を備え、計器用変圧器・避雷器盤、フィーダ盤及び母線変換盤の奥行寸法をそれぞれ電力需給用計器用変成器盤の奥行寸法の１／２以下とし、受電盤及び母線変換盤をＶＣＴ接続盤と背面合わせの状態で配置し、受電盤及び母線変換盤の間に、計器用変圧器・避雷器盤及び２台のフィーダ盤を電力需給用計器用変成器盤と背面合わせの状態で配置したので、各盤を効率良く配置し、全体を小形化することができる。
【００３７】
さらに、この発明の金属閉鎖形スイッチギヤは、受電盤、フィーダ盤及び計器用変圧器・避雷器盤の高さ寸法を１９００ｍｍ以下とし、電力需給用計器用変成器盤の筐体を、高さ寸法１９００ｍｍ以下の複数の分割筐体に分割可能としたので、据付搬入時に、一般のエレベータを用いることができ、クレーンなどの設備が不要となり、コストダウンを図ることができる。
