Abstract

PURPOSE:To make it possible to obtain a compact and light weight equipment, by indirectly grounding one terminal (facing the wire end of the other winding) of the stabilizing winding, which is wound around one leg and has no direct grounding terminal, through a surge absorbing capacitor, and directly grounding the terminals of the other windings. CONSTITUTION:With respect to cores 1, 2 and 3, the stabilizing windings 4, 5 and 6 are provided at an innermost part, low voltage windings 7, 8, and 9 are provided in the middle, and high voltage windings are provided at an outermost part. The high voltage windings 10, 11, 12 are Y-connected with respect to wire terminal U, V, and W and a neutral point 14. The low voltage windings 7, 8, and 9 are Y-connected with respect to wire terminals u, v, and w and a neutral point 13. The stabilizing winding 4, 5, and 6 are DELTA-connected by winding terminals (a), (b), and (c), and one terminal of each winding is grounded. Since the top terminal (a) of the stabilizing winding 6 which is wound around the third core 3 is grounded, the winding direction is reversed. One terminal (b) of the stabilizing winding 5 which has no direct ground terminal is indirectly grounded via the surge absorbing capacitor 15.
