Abstract

PURPOSE:To prevent the local overheating of the devided section caused by leakage flux by covering the upper and the lower divisions of the tank of a transformer with the protruded section of the electromagnetic shield. CONSTITUTION:A winding 16 is attached to an iron core 15, and it is tightened by an iron core set fitting member 17 by means of a winding end insulation material 18. Then, together with insulating oil 19, it is contained in the container, in which an upper tank 11 with an upper flange 11b and a lower tank 12 with a lower flange 12b are sealed with a grasket 13. Then, the upper tank 11 is formed, so that its inside measurements exceed a bit those of the lower tank 12. A plate-typed electromagnetic shield 20, made of aluminum or copper with a high conductivity, is provided on a side wall 12a. Then, the protruded section 20a of the shield is stretched out upward above the lower flange 12a, so that the occurrence of local overheating, caused by the leakage flux, at the side wall of the tank can be prevented.
