<p><P>PROBLEM TO BE SOLVED: To provide a stationary induction apparatus capable of preventing local overheating of a lower fastening metal fitting, without causing an increase in size as a result of using a non-magnetic shield. <P>SOLUTION: A lower fastening metal fitting 5 is shaped into a box having an insulation oil channel 10, which is made of a back surface member 5a, a bottom surface member 5b, a front surface member 5c and an upper surface member 5d. An oil through-hole 12 for insulation oil is formed on the upper surface member 5d of the lower fastening metal fitting 5. A non-magnetic shield 20 arranged between the lower fastening metal fitting 5 and a lower support insulator 8 for winding wires 4a and 4b is attached in a flat plate shape, as with the upper surface member 5d of the lower fastening metal fitting 5. Moreover, part of the flat plate shape of the non-magnetic shield 20 is elongated in a direction intersecting the surface of the upper surface member 5d of the lower fastening metal fitting 5. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
