Description
【０００１】
【発明の属する技術分野】
本発明はガス絶縁静止誘導電器に係り、特に、複数の単位が分割して設置されると共に、これらが三相結線され、かつ、ＳＦ6 ガス等の絶縁ガスが封入されているものに好適なガス絶縁静止誘導電器に関する。
【０００２】
【従来の技術】
静止誘導電器のタンクには、例えば特開昭５６−４２１８号公報に示されているようなタンクが採用されている。このようなタンクを用いた静止誘導電器は、通常、敷地面積をできるだけ小さくするために、各種リード線（一次，二次、及び三次リード線，二次中性点リード線，タップリード線等）をタンク上面より引き出して各単位間の接続をしている。
【０００３】
【発明が解決しようとする課題】
ところで、地下変電所等に設置する静止誘導電器に、上述した従来技術の方式を採用すると、タンク上面よりリード線を引き出すことになるので、リード線を収納しているリード線用ダクトの分だけ高さが必要となり、地下変電所に採用する場合には地下の掘削深さが大きくなってしまい、地下変電所の建設コストが増加するという欠点があった。
【０００４】
本発明は上述の点に鑑みなされたもので、その目的とするところは、装置全体を単純、かつ、小型化して地下変電所に採用する場合であっても建設コストが大幅に低減可能なガス絶縁静止誘導電器を提供するにある。
【０００５】
【課題を解決するための手段】
本発明では上記目的を達成するために、１つの単位を単相構成とし、１単位ごとに絶縁ガスが封入され、少なくとも巻線と鉄心からなる中身を収納してなる複数個のタンクを竪置きに設置すると共に、これらを略Ｌ字状に配置し、かつ、Ｌ字状配置の両端部に位置するタンクとで略逆Ｌ字状を形成するようにタップ切換器が配置され、前記複数個の各タンクの側面からタップリード線をそれぞれ引き出すと共に、該各タップリード線は、収納されているタップリード線用ダクト越しに前記タップ切換器に接続され、前記Ｌ字状に配置されている中央のタンク側面から引き出された前記タップリード線は、Ｌ字状配置の両端部に位置するタンクの間を通って前記タップ切換器に接続されていることを特徴とする。
【０００９】
【発明の実施の形態】
以下、図示した実施例に基づいて本発明のガス絶縁静止誘導電器を詳細に説明する。尚、本実施例は、ガス絶縁変圧器を例にして説明する。
【００１０】
図１に本発明のガス絶縁変圧器の一実施例を示す。該図に示す如く、本実施例のガス絶縁変圧器は、鉄心１と巻線２などで構成される中身が、１つの単位を単相構成とし、１単位ごとにＳＦ6 ガスを封入した円筒形タンク３内に収納されて構成され、これらが複数個配置されている。
上記各円筒形タンク３は竪置きに設置され、これらが略Ｌ字状に配置されており、かつ、Ｌ字状配置の両端部に位置する円筒形タンク３とで略逆Ｌ字状を形成するように負荷時タップ切換器４が配置されている。また、各円筒形タンク３の側面からタップリード線１３をそれぞれ引き出すと共に、各タップリード線１３は、収納されているタップリード線用ダクト１５越しに負荷時タップ切換器４に接続されている。そして、Ｌ字状に配置されている中央の円筒形タンク３の側面から引き出されたタップリード線１３は、Ｌ字状配置の両端部に位置する円筒形タンク３の間を通って負荷時タップ切換器４に接続されている。更に、各円筒形タンク３ごとに上記ＳＦ6 ガスを冷却する冷却器１４が設けられている。
【００１３】
このような本実施例の構成によれば、装置全体が単純、かつ、コンパクト化されることは勿論、円筒形タンクの内側に各リード線を収納しているリード線用ダクトの長さを短くできるため、全体の平面寸法はほとんど増加しないので、結局、ガス絶縁変圧器が単純、かつ、小型化されて地下変電所に採用する場合には、建設コストが大幅に低減されることになる。
図２に本発明のガス絶縁変圧器の他の実施例を示す。その概略構成は図１に示した構成と略同一なので、ここでの詳細説明は省略し、以下では、本発明に関連する部分を説明する。
図２に示す実施例は、複数個の各円筒形タンク３の側面からタップリード線１３をそれぞれ引き出すと共に、Ｌ字状配置の両端部に位置する円筒形タンク３の側面から引き出されたタップリード線１３は、収納されているタップリード線用ダクト１５越に負荷時タップ切換器４に接続され、かつ、Ｌ字状に配置されている中央の円筒形タンク３の側面から引き出されたタップリード線１３は、隣接する円筒形タンク３のいずれか一方の円筒形タンク３内とタップリード線用ダクト１５内を通って負荷時タップ切換器４に接続されて構成されている。
このように構成しても、その効果は上述した実施例と同様である。
【００１４】
【発明の効果】
以上説明した本発明のガス絶縁静止誘導電器によれば、装置全体が単純、かつ、小型化して地下変電所に採用する場合であっても建設コストを大幅に低減可能なガス絶縁静止誘導電器を得ることができる。

BACKGROUND OF THE INVENTION
The present invention relates to a gas-insulated static induction appliance, and is particularly suitable for a unit in which a plurality of units are divided and installed, and these are three-phase connected and an insulating gas such as SF 6 gas is enclosed. The present invention relates to a gas insulated static induction machine.
[0002]
[Prior art]
For example, a tank as shown in Japanese Patent Application Laid-Open No. 56-4218 is adopted as a tank for a static induction machine. In order to make the site area as small as possible, a static induction electric machine using such a tank usually has various lead wires (primary, secondary and tertiary lead wires, secondary neutral lead wires, tap lead wires, etc.). Is pulled out from the tank top surface to connect each unit.
[0003]
[Problems to be solved by the invention]
By the way, if the above-mentioned conventional method is adopted for a static induction electric device installed in an underground substation or the like, the lead wire is drawn out from the upper surface of the tank, so that only the lead wire duct that stores the lead wire is used. When it is used for an underground substation, the underground excavation depth becomes large, and the construction cost of the underground substation increases.
