摘要:
Leakage fluxes from windings and leads of a stationary induction apparatus are confined within a tank. The stationary induction apparatus includes an electric functional units each including a winding and a core, a tank containing the electric functional units, high-voltage leads leading out from the windings, and low-voltage leads leading out from the windings. Magnetic shields are placed on the inner surface of a wall of the tank through which the high-voltage leads are drawn out of the tank, and a composite shield formed by combining nonmagnetic shields and magnetic shields is placed on the inner surface of a wall of the tank facing the low-voltage leads and is electrically short-circuited.
