Transformer device

A transformer device comprising:

• a transformer including a core and a coil wound around the core;
• a suspension tool attachment unit disposed above the coil and connected to the core;
• and
• a cover body having an internal space that accommodates the transformer and connected to the suspension tool attachment unit, wherein
• a suspension tool for suspending the transformer device including the transformer and the cover body is attachable to the suspension tool attachment unit,
• the transformer includes a first phase transformer, a second phase transformer stacked above the first phase transformer, and a third phase transformer stacked above the second phase transformer,
• the suspension tool attachment unit is connected to the core of the third phase transformer,
• the transformer device further comprises:
• a first connection member that connects the core of the first phase transformer and the core of the second phase transformer;
• a second connection member that connects the core of the second phase transformer and the core of the third phase transformer;
• and
• a lower frame disposed below the first phase transformer and connected to the first phase transformer,
• the cover body is supported by the suspension tool attachment unit and the lower frame,
• the cover body is provided with:
• a first opening located below the first phase transformer and allowing communication between the internal space and a space outside the internal space;
• and
• a second opening located above the third phase transformer and allowing communication between the internal space and the space outside the internal space, and
• an air flow is formed such that air flows into the internal space through the first opening and is discharged to the space outside the internal space through the second opening.
