Three-step core for a non-linear transformer |
摘要 |
A three step non-linear transformer core is formed from three sections of laminations each having different widths and cross-sectional areas. A first section of laminations is formed by cross-slitting a generally rectangular sheet or strip of metal. A resulting generally triangular segment is then wound upon a mold to form a first section of a core frame having a trapezoidal cross section. A second section of laminations is wound upon the first section of laminations to form a segment of a core frame having a rhombic cross section. The third section of laminations is wound upon the second section of laminations to form a segment of a core frame having a trapezoidal cross section. Each of the first, second, and third sections of laminations are offset from one another by a predetermined angle of offset. |
