<P>PROBLEM TO BE SOLVED: To reduce noise of a stationary induction apparatus, improve dielectric voltage in a portion of a tank where high voltage is applied, and shorten the insulation distance to reduce the size of the tank. <P>SOLUTION: This invention is applied to a stationary induction apparatus in which a stationary induction apparatus body formed by an iron core 1 and a winding wire 2 is housed in a tank 7 with a cooling insulation medium 3 and a non-magnetic shield 8 is disposed on an inner wall side surface 6 of the tank 7. An insulator 9 is disposed at an area on a surface of the nonmagnetic shield 8 which is located between a charging part 5 of the winding wire 2 and the nonmagnetic shield 8 and faces at least the charging part 5 of the winding wire 2. <P>COPYRIGHT: (C)2012,JPO&INPIT |
