Abstract
Изобретение относится к магнитопроводу трансформатора с внутренней частью магнитопровода из магнетизированного материала. Магнитные потоки рассеяния создают во внешних областях магнитопровода вихревые токи, которые приводят к потерям мощности и высоким локальным нагревам. За счет частично покрывающего внутреннюю часть магнитопровода экрана из, по меньшей мере, одного шихтованного магнитомягкого материала, потоки рассеяния канализируют и отводят от внешней области внутренней части магнитопровода. Это приводит к сильному уменьшению образования вихревых токов во внутренней части магнитопровода и, тем самым, препятствует сильным локальным нагревам магнитопровода трансформатора и потерям мощности.
