Abstract

PURPOSE:To absorb leaked magnetic flux, by setting ferromagnetic materal extending over the upper and lower magnetic clamps at the position opposite to the lead drawing part of the magnetic clamp on the tank side in a stationary induction apparatus which is contained in a tank. CONSTITUTION:Iron core clamping fixtures 4, 5 are applied on the both side surfaces of iron core yokes 2, 3, and coaxially wound-up inside and outside windings 6, 7 are strongly pressed from above and below to be securely fixed on the iron leg 1. On the side of a tank 8 opposite to the high voltage lead wire 11 drawing opening 12 formed in the ring-shaped magnetic clamp 9 loaded between the yoke 2 and winding 6, 7, ferromagnetic material 13 extending in vertical direction over the upper and lower clamps 9, 10 is installed via non-magnetic insulator. The material 13 is constituted by laminating band iron plates consisting of a plurality of silicon steel plates, etc. parallel to the side of the tank 8, having the width with approximately the same dimension as the opening 12. Thus, the majority of the leaked magnetic flux from windings can be absorbed by the material 13.
