Summary:PROBLEM TO BE SOLVED: To provide an inexpensive stationary induction apparatus having a magnetic shield that suitably prevents leakage magnetic flux from being incident from winding to suppress damage on a tank, and then facilitates manufacturing operation and has a configuration imposing no restriction on transportation. SOLUTION: A stationary induction apparatus body 10 formed by winding the winding 12 around a center part of an iron core 11 is stored in the tank 20 filled with insulating oil. A magnetic material shield 30 is mounted on a tank side face 20e by magnetic shielding, and an iron plate shield 40 is mounted on an upper inclined face 20f and a lower inclined face 20g of the tank. The iron plate shield 40 absorbs leakage magnetic flux which travels not to the magnetic shield 30, but to the upper inclined face 20f and lower inclined face 20g. COPYRIGHT: (C)2011,JPO&INPIT
