Abstract
Description
φv=φ0・sin(2πf・t−2π/3) …(2)
φw=φ0・sin(2πf・t−4π/3) …(3)
但し、f:交流周波数、φ0:最大磁束
そして、各主磁束の間には時間によらず、以下の関係式が成り立つ。
上式は、主磁路1の三脚交点部位5に対して流入する主磁束と流出する主磁束が等しくなること、制御用磁路10には主磁束が通過しないことを意味している。実際には交点部位5との接続付近において主磁束の漏れ成分が通過することになるが、この主磁束の漏れ成分の、図2において矢印で示した制御磁束φcの方向成分の和は0となる。なお、各巻線には、主磁路1の磁気抵抗に応じて各主磁束を発生させるのに必要な励磁電流Iu、Iv、Iwが各々流れることになる。各主磁束の大きさと励磁電流の大きさの比率がリアクタンスに相当し、主磁路1の磁気抵抗が大きい程リアクタンスは小さくなるという関係がある。
Claims (4)
- N相N脚の主磁路(但しNは3以上)と、各主脚に巻き回した主巻線を有するとともに、N個の主脚の交点部位でN相の主磁束の何れとも概略直交する方向に大きさが可変な制御磁束を発生させる制御磁束発生手段を設け、当該発生手段により制御磁束の大きさを制御することによりN相リアクタンスを可変することを特徴とする多相型静止誘導電器。
- 請求項1に記載の前記交点部位が360/N°回転対称形状に形成されたことを特徴とする多相型静止誘導電器。
- 請求項1または2に記載の前記交点部位において軸対称形状の制御磁束を発生させることを特徴とする多相型静止誘導電器。
- 請求項1、2または3のいずれかに記載の前記制御磁束発生手段において、制御磁束の大きさの時間変動を抑制する補償巻線を有することを特徴とする多相型静止誘導電器。
