FIELD: electricity.SUBSTANCE: invention relates to electrical engineering. The system comprises at least two coils (1, 4) placed at common core rod (7) in axial direction over each other at common core rod. Each coil has at least two windings (2, 3, 5, 6) placed in radial direction over each other, and there are barriers between windings (2, 3, 5, 6). Barriers (9-13, 15-19) of neighbouring coils (1, 4) are placed with offset in radial direction in regard to each other. Edge areas of the barriers (9-13, 15-19) are inserted into each other in comb-like way. As alternative the barriers (21-25, 27-31) in areas of the neighbouring coils (1, 4) placed in direct opposition towards each other are shortened and prolonged by turns so that opposite a shortened barrier (21, 23, 25) of one coils (1) there is always a prolonged barrier (27, 29, 31) of the other coil (4), and vice a versa, opposite to a prolonged barrier (22, 24) of one coil (1) there is always a shortened barrier (28, 30) of the other coil (4), and in each coil (1, 4) a shortened barrier follows the prolonged one. Al alternative barriers are made partially as insulating rings (34/35, 38/39, 43/44, 47/48), which cover additionally end surfaces of windings (2, 3, 5, 6) placed perpendicular to the winding axis (W).EFFECT: improved electric strength.8 cl, 4 dwg |
