Abstract

Se proporciona una lámina de acero eléctrico de grano orientado, excelente en términos de proporcionar un efecto de reducción de la pérdida de hierro de un transformador cuando se utiliza para un núcleo apilado de un transformador. En la lámina de acero eléctrico de grano orientado utilizada para un núcleo apilado de un transformador, el espesor t de la lámina de acero y la proporción del deterioro de la pérdida de hierro que se obtienen al someter la lámina de acero a una magnetización elíptica definida mediante la fórmula (1) siguiente cumplen las siguientes condiciones: cuando el espesor t de la lámina de acero ??0.20 mm, la proporción de deterioro de la pérdida de hierro es de 85% o menos; cuando 0.20 mm < espesor t de la lámina de acero < 0.27 mm, la proporción de deterioro de la pérdida de hierro es de 80% o menos; y cuando 0.27 mm ??al espesor t de la lámina de acero, la proporción de deterioro de la pérdida de hierro es de 75% o menos. (La proporción de deterioro de la pérdida de hierro bajo magnetización elíptica) = ((WAWB)/ WB )?100 (1) En la fórmula (1) WA corresponde a la pérdida de hierro bajo una magnetización elíptica a 50 Hz de 1.7 T en una dirección RD (dirección de laminación) y de 1.0 T en una dirección TD (una dirección ortogonal a la dirección de laminación), mientras que WB corresponde a la pérdida de hierro bajo una magnetización alternante a 50 Hz de 1.7 T en la dirección RD.
