Abstract:
A stationary induction apparatus comprising:electric functional units for three phases each including a winding and a core; a tank containing the electric functional units; high-voltage leads leading out respectively from the windings and extended through through holes formed in a wall of the tank facing the high-voltage leads at positions laterally dislocated from positions directly opposite the windings; low-voltage leads leading out respectively from the windings on a side opposite a side on which the high-voltage leads are extended, and extended vertically along a wall of the tank facing the low-voltage leads; and magnetic flux producing means for producing magnetic flux of a polarity opposite that of leakage fluxes from the windings and the low-voltage leads by eddy currents induced by the leakage fluxes, said magnetic flux producing means being placed on an inner surface of the wall of the tank including regions facing the low-voltage leads.
