| 摘要 |
The present invention relates to cores and coils for electrical transformers in which lateral walls of either Wescore or toroidal type cores are manufactured by winding strips of different heights or only one strip whose width reduces gradually, so that said lateral walls form an angle relative to the core upper wall. The corresponding coil is manufactured following the core pattern, on which core the coil will be placed or wound. The use of the cores and coils of the present invention achieves substantial savings in materials used to manufacture electrical transformers, while the resulting characteristics and electrical losses are improved, with load and with no-load. <IMAGE> |
