摘要:
While the whole weight of magnetic shields provided in a tank of a transformer is reduced, eddy current loss by magnetic flux leaked from a winding is reduced. A transformer is configured using an iron core having an iron core leg and an iron core yoke, windings wound around the iron core leg, a tank having the iron core and the windings therein, and a first magnetic shield and second magnetic shields formed by laminating silicon steel sheets inside the tank. The first magnetic shield is arranged opposite to the windings, the second magnetic shields are arranged between the first magnetic shield and the tank, and the first magnetic shield and the second magnetic shields are fixed to the tank by different support members.
