PROBLEM TO BE SOLVED: To provide a stationary induction electric apparatus capable of achieving cooling design of a coil without restriction on an arrangement place of a bent flow plate by suppressing occurrence of a high electric field around the bent flow plate.SOLUTION: A stationary induction electric apparatus includes: an inner insulation cylinder disposed so as to surround an iron core leg; an outer insulation cylinder disposed concentrically to and on an outer side of the inner insulation cylinder; disc coils disposed between the inner insulation cylinder and the outer insulation cylinder and laminated in an axial direction; horizontal spacers disposed between the laminated disc coils so as to form ducts in a horizontal direction; vertical spacers disposed between the disc coils and the inner insulation cylinder and between the disc coils and the outer insulation cylinder so as to form ducts in the vertical direction; and bent flow plates disposed between the laminated disc coils so as to form bent flow sections having a plurality of disc coils. Between one ends in a radial direction of the bent flow plates and the inner insulation cylinder or the outer insulation cylinder, gaps are alternately formed in the axial direction of the disc coils, and the other ends in the radial direction of the bent flow plates have curvature. |
