Three-phase three-column amorphous alloy core is suitable for manufacturing Yy and Dy style transformers.And the transformer which make by three phase amorphous core has the features below harmonious and beautiful dimension ,small overlooking area,better economical efficiency of product structure.When high-capacity transformer uses this kind of structure, it should choose the suitable craftsmanship.
Under 50Hz and normal temperature,the range of magnetic flux density of three phase three column will be between 1.15-1.35T,the no-load core loss and exciting power of the cores which made by the ribbon of lamination factor of 0.86 and width of 142 and 170 should match the requirements below :
| Field density/T |
1.150 |
1.200 |
1.25 |
1.3 |
1.35 |
| Core loss(W/Kg) |
0.160 |
0.180 |
0.200 |
0.220 |
0.250 |
| Excitation(VA/kg) |
0.300 |
0.350 |
0.425 |
0.550 |
