Plakhtyr O. Improvement of three-phased transformers with spatial magnetic cores

The spatial electromagnetic systems (SEMS) are systemized on the base of offered signs of the shaping surfaces (SS) of winding windows and rods and analysis of constructive-technological particularities of magnetic cores’ construction, their decisions are concidered. It is shonw that new unconvetional SEMS with SS differ by the maximum possibilities and quantity of performance variations of the active part (AP). The method of comparing analysis of constructive schemes of SEMS is designed on quantative technical level factors, special purpose functions of geometrical optimization of AP and auxilary perfection signs of magnetic cores. The dependences of the main quantity factors of three-pnased transformers with jointed spatial magnetic cores on a construction scheme form and AP’s geometrical correlations are researched. The constructive-technological decisions are offered and the possibilities of increasing the technical level and power in volume unit of three-phased transformers’ SEMS by using magnetic cores with parrelel SS are shown.
