Amorphous Alloy Distribution Transformer

An amorphous alloy distribution transformer uses a new type of magnetic permeability material: amorphous alloy. The iron core is composed of amorphous alloy and is structured with three phases and five columns. The amorphous alloy core undergoes annealing treatment, and the iron yoke is staggeringly jointed. Both the iron core and winding coils have rectangular cross sections.

These transformers are widely used in industrial engineering, agriculture, and urban communities, particularly in power networks in rural and developing areas.

Three Phase Amorphous Alloy Distribution Transformer

1. The no-load loss of amorphous alloy transformers is more than 65% lower than that of S11 transformers, and the no-load current is reduced by about 80%, leading to an average annual operating cost reduction of 22.7%.
2. The transformers have no structural loss, and the iron core adopts a three-phase, four-frame, five-column structure. Zero-sequence magnetic flux flows through the columns on both sides, without passing through the box, thereby preventing heating-related structural losses.
3. The transformer's connection group uses Dyn11 to reduce the impact of harmonics on the power grid and improve power supply quality.
4. The low-voltage winding of the transformer uses copper foil coils, with the coils being round and rectangular.
5. The transformer body structure adopts an "upper branch and lower branch" design to minimize stress on the iron core and ensure the electromagnetic performance of the amorphous alloy iron core.
6. The small-capacity transformers package uses vertical packaging technology, while the large-capacity transformers package uses horizontal packaging technology to strictly control noise and no-load loss.
7. The transformers box adopts a fully enclosed structure, filled with silicone oil that has excellent anti-oxidation, high-temperature resistance, and thermal cycle properties, making the transformers essentially maintenance-free.
8. The transformers uses vacuum oil filling to completely eliminate air bubbles in the coil and ensure the stability of the insulation performance.
9. A protective cover is installed above the high and low voltage bushings of the transformers to prevent any exposed conductors, and cable routing is used to achieve full insulation protection.
