FIELD: electrical engineering; can be used in heavy-current equipment, in particular, in devices for resistance welding, for supply of induction furnaces, etc. SUBSTANCE: in transformer, using primary winding 2 positioned on toroidal core 1 and secondary winding 3 enveloping the primary one, the secondary winding represents q bundle of non-insulated flexible conductors laid in insulated sections 4,5,6; at transitions from the hole to the external side of toroidal core 1 and back to the hole the bundles are fan-shaped. EFFECT: enhanced adaptability to manufacture, reduced dimensions and loss. 1 dwg |
