| 摘要 | PURPOSE:To eliminate measure for preventing heating due to leakage flux to peripheral structure of iron core and tank by setting a yoke sectional area of iron core of series transformer to a reasonable value corresponding to sectional area of main leg of iron core. CONSTITUTION:The exciting winding 21 and series winding 22 of series transformer of phase regulator are arranged in the sequence of windings 21, 22 from the side of iron core leg 23 and are connected to windings 11, 12 of regulated transformer 1. Meanwhile, an iron core 20 is composed of a main leg of iron core 23 and a yoke 24. with the 3-phase, 3-leg iron core structure, the sectional area of yoke 24 is formed larger than that of main leg 23 by VS'/VS (phi1+phi2)/phi1 times. Where, phi1 is main magnetic flux for inducing voltage to each winding, phi2 is leakage magnetic flux due to a load current, VS, VS' are series winding voltages under the loading or unloading conditions. Therefore, since the leakage magnetic flux phi2 can be fed back within the yoke 24 as in the case of magnetic flux phi1, the leakage magnetic flux returning through the peripheral structure of iron core and tank can be reduced remarkably and measures for leakage magnetic flux can be eliminated. | ||||||
