Technological Parameters Of The Magnetic Circuit Of The Compact Transformer For Aggregate Electric Drive

Abstract

One of the energy and resource saving ways in development of electromechanical systems is system aggregation: combining electric motors, converters and transformers in common ventilated units. The modern improvement of three-phase transformers trend is the use of symmetric spatial electromagnetic systems with twisted three-section magnetic circuits. Such transformers characterized by embedding in the cylindrical shells of aggregates of block electrical equipment convenience. In addition, spatial electromagnetic systems can improve the three-phase transformers technical level relative to planar counterparts. In the work, calculated expressions of three-phase compact transformer twisted spatial axial magnetic circuit's electrical steel sectional workpieces geometric parameters are obtained. The named parameters are determined based on optimization controlled variables extreme values.
