【発明の詳細な説明】
【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ているものにおいて、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、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。

Description: TECHNICAL FIELD [Detailed description of the invention]
[0001]
[Technical field to which the invention belongs]
The present invention receives and distributes electric power.Metal closure switch gearIn particular, it relates to the board size and the board layout.
0002.
[Conventional technology]
FIG. 9 is a circuit diagram showing an example of a skeleton of a one-line power receiving method among various power receiving methods. The one-line power receiving system skeleton includes a power receiving unit 1, a power supply and demand instrument transformer (hereinafter abbreviated as VCT) provided by an electric power company and connected to the power receiving unit 1, an instrument transformer 3, a lightning arrester 4, and a lightning arrester. It is composed of a plurality of feeder units 5.
0003
The power receiving unit 1 includes a circuit breaker 6, a pair of disconnectors 7 connected in series on both sides of the circuit breaker 6, a plurality of ground switches 8, and an instrument transformer 9. The feeder unit 5 includes a disconnector 10, a ground switch 11, a circuit breaker 12, and an instrument transformer 13.
0004
FIG. 10 is a block skeleton diagram (planar configuration diagram) showing an example in which the skeleton of FIG. 9 is configured by using a conventional extra-high metal closed type switch gear, and FIG. 11 shows the appearance of the extra-high metal closed type switch gear of FIG. It is a perspective view which shows. The power receiving unit 1 is housed in the power receiving board 14, and the VCT 2 is housed in the VCT board 15. The voltage transformer 3 and the lightning arrester 4 are housed in the voltage transformer / lightning arrester panel 16. Each feeder unit 5 is housed in a feeder board 17.
0005
The power receiving board 14, the VCT board 15, the instrument transformer / lightning arrester board 16, and the feeder board 17 are installed side by side in a horizontal row. The depth and height dimensions of the boards 14 to 17 are aligned with each other in accordance with the depth and height dimensions of the VCT board 15, which is the maximum size of the internal equipment configuration. However, the width dimension of each board is configured according to the width dimension of each internal device configuration.
0006
[Problems to be Solved by the Invention]
In the conventional extra-high metal closed switch gear configured as described above, the depth and height dimensions of the power receiving board 14, the voltage transformer / lightning arrester board 16 and the feeder board 17 are the largest VCT board 15. Since it is decided together, the entire device becomes large and causes an increase in cost. In addition, since the heights of the panels 14 to 17 are high for installation and loading, equipment such as a crane is required because it cannot be used in a general elevator, which also causes an increase in cost.
