PROBLEM TO BE SOLVED: To provide a stationary induction electrical apparatus which suppresses a loss by preventing local heating caused by concentrating an eddy current to a bolt which fixes divided iron core fastening metal fittings or lacking a contact face between the iron core fastening metal fittings.SOLUTION: A lower yoke 3 is formed to be divided into leg yokes 3A and an intermediate yoke 3B connecting the leg yokes 3A. The leg yokes 3A and the intermediate yoke 3B are fastened and fixed by leg iron core fastening metal fittings 6A and an intermediate iron core fastening metal fitting 6B, respectively, and the leg iron core fastening metal fittings 6A and the intermediate iron core fastening metal fitting 6B are mechanically connected by a bolt. A shorting bar 20 formed from a non-magnetic substance of which the electric resistivity is lower than that of the intermediate iron core fastening metal fitting 6B, is disposed over mechanically connecting parts of the leg iron core fastening metal fittings 6A and the intermediate iron core fastening metal fitting 6B, and electrically connected with the leg iron core fastening metal fittings 6A. |
