A three phase transformer relates to electrical engineering, specifically to transformer development and manufacturing, and can be used in electric power industry, machinery engineering, radio engineering, metallurgy, aviation engineering, ship-building and other industries. Disclosed is a three-phase transformer, whose spatial magnetic system comprises three modules each of which is parallelepiped-shaped with a cross-section as three parallel located bars coupled by two cores, the windings are located at the middle bar; three modules, each of which corresponds to the transformer phase, form the three-phase transformer by three methods: mechanical uniting three modules into a whole unit by the side bar surfaces or core surfaces, or each module is located separately, operates independently and is the transformer phase. The proposed transformer provides for technology simplification, time reduction, cost reduction and increasing quality of design stages, manufacturing, service and repairing of transformers, improvement characteristics thereof due to lowering noise and vibrations, solving a problem of transportation from a plant to operational location, manufacturing power transformers in dry-running manner. |
