| Features of shell-type rectiformer |
 |
- Transformer and rectifier built in a unit (with the size reduced
to half, 6000 kW as compared with conventional Mitsubishi device)
- Realization of thin tank through adoption of shell-type transformer
- Adoption of T-type connector for special, high cable
- Number of elements reduced by half through adoption of large-capacity
element (3500 A)
|
 |
- The total transformer loss is reduced by 30% to realize the installation
of a radiator at one side (6000 kW as compared with conventional Mitsubishi
device).
|
 |
- Hydrofluoroether (HFF) is adopted for the rectifier refrigerant
as an anathermal countermeasure.
- Transformer noise is reduced by increasing the core sectional area
(that eventually decreases the magnetic flux density).
|
 |
- The rectangular coil allows easier interleaving, ensuring higher
degree of freedom in design and applicable to various specifications.
- The use of form-fit tank makes the device compact, reducing the
oil quantity.
- The 3-phase, 5-leg core configuration makes the tank thin.Low noise
