Claims (3)
- 中性点に対してそれぞれ対称に設けられた複数のタップを有する単巻変圧器と、前記単巻変圧器に接続され同一構成を有する第1及び第2タップ切替部と、該タップ切替部を制御する制御部とを具備し、
各タップ切替部は、前記複数のタップのうち1つを前記中性点に接続するスイッチと、前記単巻変圧器の一端と前記中性点間の電圧を検出する電圧センサとを具備し、前記各単巻変圧器の一端と前記中性点の間にはそれぞれ異なる負荷が接続され、
前記制御部は前記各電圧センサにて検出された電圧が、第1基準電圧以上となった場合あるいは第1基準電圧より低い第2基準電圧以下となった場合、前記スイッチを流れる電流が0付近のタイミングでタップが切替るよう前記各スイッチを独立に制御することを特徴とする電圧調整装置。 - タップ切替えする前記タイミングは、励磁電流のゼロクロスポイント前後の位相角±30°以内の時点であることを特徴とする請求項1記載の電圧調整装置。
- タップ切替えする前記タイミングは、前記電圧センサにて検出された電圧のゼロクロスポイントから90°位相が遅れた時点前後の位相角±30°以内の時点であることを特徴とする請求項1記載の電圧調整装置。
