Abstract

LA INVENCION SE REFIERE A UN TRANSFORMADOR SECO O A UNA BOBINA DE CHOQUE EN LA QUE LOS CONDUCTORES ARROLLADOS Y/O LAS CAPAS ARROLLADOS Y/O REVESTIMIENTOS EXTERIORES DE AL MENOS UN ARROLLAMIENTO (2, 3) ESTAN AISLADOS. DE FORMA ALTERNATIVA, AL MENOS UN ARROLLAMIENTO Y UN NUCLEO (1, 11) DE HIERRO CON LOS ARROLLAMIENTOS (2, 13) PUEDEN ESTAR COMPLETAMENTE RODEADOS POR RESINA (3) CERAMICA. PARA PRODUCIR LA RESINA CERAMICA UNA SOLUCION ALCALINA FUERTE CON SODIO Y/O POTASIO Y/O CALCIO Y/O LITIO SE PREPARA CON UN POLVO DE SILICATO Y ALUMINIO. ALTERNATIVAMENTE, HILOS DE FIBRA PUEDEN SER REMOJADOS EN ESTA SOLUCION E INCLUIDOS SOBRE EL ARROLLAMIENTO O EN EL ARROLLAMIENTO O EN EL NUCLEO DE HIERRO CON ARROLLAMIENTOS COLOCADOS DENTRO DE MOLDES EN ESTA SOLUCION COLADA. ESTE PROCESO ES SEGUIDO POR OTRO DE MADURACION A TEMPERATURA DE 70 HASTA 100 SER SEGUIDA DE UNA INMERSION EN UN LIQUIDO CON BUENAS PROPIEDADES DIELECTRICAS.
