Title:
THREE-PHASE TRIPOD WOUND IRON CORE AND THREE-PHASE TRIPOD WOUND IRON CORE TRANSFORMER USING THE SAME
Document Type and Number:
Japanese Patent JP2023146181
Kind Code:
A
Abstract:
To provide a three-phase tripod wound iron core with an excellent reduction efficiency and a noise reduction efficiency of a transformer iron loss.SOLUTION: A three-phase tripod wound iron core is formed by an external side iron core, and two inner iron cores which are alternately distributed into an inner side of the external side iron core. Each of the external side iron core and the two inner side iron cores is constructed by at least two types of direction electromagnetic steel plate having a different magnetic flux density in 800A/m. An inner side part of the external side iron core and an outer side part of the two inner side iron cores are constructed by a direction electromagnetic steel plate of which the magnetic flux density in 800A/m is smaller than that of the direction electromagnetic steel plate constructing the external part of the external side iron core and the internal side part of the two inner side iron cores.SELECTED DRAWING: None
