【発明の属する技術分野】
本発明は三相負荷時電圧位相調整変圧器に係り、特に送電系統に接続された状態で、電圧調整と位相調整を独立して行うことができる三相負荷時電圧位相調整変圧器に関する。
【０００２】
【従来の技術】
従来の三相負荷時電圧位相調整変圧器は、特開平７−２５４５２０号公報に示すように、主変圧器と、この主変圧器とは別置に設けられた位相調整器とから構成されている。
【０００３】
この様な構成では、主変圧器には、一次巻線，電圧調整用タップ巻線，二次巻線、および三角結線の三次巻線が備えられ、位相調整器には、星型結線の励磁巻線，位相調整用タップ巻線、および三角結線の安定巻線が備えられている。しかも、主変圧器側の三角結線の三次巻線と位相調整器側の星型結線の励磁巻線とは並列接続されている。
【０００４】
【発明が解決しようとする課題】
このように構成されている従来の三相負荷時電圧位相調整変圧器では、別置形の位相調整器が、主変圧器の三次側に接続される負荷となり、実際の主変圧器の三次外部負荷となる三次調相設備として接続可能な容量が制限を受けるという欠点があった。
【０００５】
また、主変圧器と位相調整器のための据付基礎面積が必要であり、変電所総合コストを高める１要因となっていた。
【０００６】
本発明はこれに鑑みなされたもので、その目的とするところは、主変圧器側で電圧調整のみならず、位相調整も可能なことは勿論、別置形の位相調整器を不要とし、据付基礎面積の縮小化が図れ、変電所総合コストを抑えることのできる三相負荷時電圧位相調整変圧器を提供するにある。
【０００７】
【課題を解決するための手段】
本発明の三相負荷時電圧位相調整変圧器は、上記目的を達成するために、主変圧器側に設けられている電圧調整用タップ巻線に加え、前記一次主巻線の各相ごとに２個の位相調整用タップ巻線を備え、その２個の位相調整用タップ巻線を、位相調整用二相形負荷時タップ切換器により１２０度位相で電気的に接続し、前記一次主巻線の電圧位相に対して９０度位相の電圧を発生させることを特徴とする。
【０００８】
【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を詳細に説明する。
【０００９】
図１は本発明の三相負荷時電圧位相調整変圧器の概略巻線構成を、図２はその変圧器の一次タップ巻線構成を示す。該図において、一次巻線（Ｖ相）は、一次主巻線１，電圧調整用タップ巻線２、および当該相似外の２相（Ｕ相，Ｗ相）の位相調整用タップ巻線４と５を備えている。そして、２相の位相調整用タップ巻線とは、１２０度位相となるように位相調整用二相形タップ切換器６にて接続される。これにより当該一次巻線１に対し、
９０度位相を持った電圧を得る。そして、一次巻線の中性点側に配置された電圧調整用タップ巻線２に接続される。各相の電圧調整用タップ巻線２は一次巻線が星形結線となるように構成され、その中性点部に電圧調整用三相形負荷時タップ切換器３が取り付けられている。
【００１０】
以上のように構成された一次巻線を持った三相負荷時電圧位相調整変圧器であれば、一次巻線の一部である電圧調整用タップ巻線２の巻回数とその誘起電圧の向きを、電圧調整用三相形負荷時タップ切換器３によって調整し、二次巻線との巻数比を換えることにより、電圧の大きさを調整するとともに、さらに位相調整用二相形負荷時タップ切換器６により位相調整用タップ巻線４と５の巻回数とその誘起電圧の向きを調整するこれにより、二次側に誘起する電圧に対して一次側に誘起する電圧の位相角を調整することができる。
【００１１】
この様に構成された一次巻線を持った三相負荷時電圧位相調整変圧器であると、主変圧器側で電圧調整と位相調整が可能なことは勿論、従来設置していた別置形位相調整器が不要となり、三次側に接続可能な調相設備の容量制限もなくなり、かつ据付基礎面積も縮小されることから、変電所総合コストの低減が図れるという効果がある。
【００１２】
【発明の効果】
以上説明した本発明によれば、主変圧器側で電圧調整と位相調整が可能となり、従来設置していた位相調整器を不要とすることができ、据付基礎面積の縮小化が図れ、ひいては変電所総合コストの低減につながり、此種変圧器には有効である。
