PURPOSE:To adopt the through-conductor type even in a high voltage region by providing a pair of meandering conductors which pass through the window of iron core and by sequentially increasing a number of windows of iron core as a terminal voltage becomes high. CONSTITUTION:Direction of currents flowing through the meandering conductors 8, 9 passing through the three windows, for example, of the iron core 7 is mutually reversed. A substantial cross-sectional area S of interphase reactor where meandering through conductors are placed through the iron core having three windows can be expressed as S=WX(3XD3). Where, W3 is width of iron core leg other than the window, W'3 is the width of iron core leg between windows, D3 is the thickness of laminated iron core. Moreover, the relation 2W3=W'3 also holds. Accordingly, since the substantial crosssectional area of iron core S can be increased easily by increasing a number of windows required, a through- conductor type interphase reactor can be adopted even for a high voltage region. |
