Abstract

Aparato inductivo eléctrico que comprende un recinto, y una primera estructura de núcleo magnético dispuesta en dicho recinto y que tiene n porciones de columnas paralelas y primeras y segundas porciones de culatas formadas a base de chapas estratificadas metálicas apiladas, estando distanciadas entre sí dichas n porciones de columnas para formar n - l aberturas entre ellas, caracterizado porque están previstas n -1 segundas estructuras de núcleos magnéticos cada una de las cuales tiene porciones de columnas y de culatas formadas de chapas estratificadas metálicas apiladas y está dispuesta en una de dicha aberturas en dicha primera estructura de núcleos magnéticos en relación separada entre sí con porciones de columnas y de culatas adyacentes de dicha primera estructura de núcleos magnéticos, de manera tal que forma una rendija completamente alrededor de la respectiva segunda estructura de núcleos magnéticos; un conjunto de arrollamientos eléctricos dispuesto en relación inductiva con dichaprimera estructura de núcleos magnéticos y con dichas n - l segundas estructuras de núcleos magnéticos; y al menos un miembro de soporte que tiene una porción de ala montada sobre el fondo de dicho recinto y dos porciones de alma paralelas que se extienden verticalmente desde él, siendo de igual longitud dichas dos porciones de alma paralela, y extendiéndose cada porción de alma dentro de la rendija entre una de dichas columnas de dicha primera estructura de núcleos magnéticos y una columna adyacente de una de dichas n-1 segundas estructuras de núcleos magnéticos.
