Transformer |
| 摘要 |
A loss in iron core clamping structures and a tank, which is caused by a leakage magnetic flux from a winding between the iron core clamping structures is reduced. In a transformer including an iron core having legs and yokes, windings wound around the legs, and ion core clamping structures arranged above and below the windings to fixedly clamp the iron core, a magnetic shield made of a material high in magnetic permeability is arranged between ends of the iron core clamping structures and the windings on a high voltage side and a low voltage side. The magnetic shield is held by a mounting member held by the ends of the iron core clamping structures in the axial direction thereof. |

1. A transformer including an iron core having legs and yokes, windings wound around the legs, and ion core clamping structures arranged above and below the windings to fixedly clamp the iron core,
wherein at least one magnetic shield made of a material high in magnetic permeability is arranged between ends of the iron core clamping structures in the axial direction thereof, and the windings. |
