Abstract

SE REVELA UNA ESTRUCTURA DE PARED PARA AISLAR LA SUPERFICIE EXTERIOR DE UNA BOBINA DE ALTO VOLTAJE TENIENDO DEVANADO ROEBELADO QUE INCLUYE UNA CAPA AISLANTE INTERIOR FORMADA DE UN MATERIAL EPOXI TEMPLABLE PARA CIRCUNDAR LA BOBINA Y RELLENAR LOS ESPACIOS HUECOS EN LA SUPERFICIE DE LA BOBINA CREADOS POR LOS DEVANADOS ROEBELADOS, UNA CAPA DE PARED A TIERRA CIRCUNDANDO LA CAPA INTERIOR PARA TOMA DE TIERRA DE LA ESTRUCTURA DE PARED, Y UNA CAPA SEMICONDUCTORA FORMADA DE UN MATERIAL EPOXI RELLENADO CON CARBON, INTEGRALMENTE MOLDEADO ALREDEDOR DE LA SUPERFICIE EXTERIOR DE LA CAPA INTERIOR AISLANTE PARA REDUCIR LA CARGA ELECTRICA A TRAVES DE LA CAPA AISLANTE Y EN PARTICULAR A TRAVES DE CUALQUIERA DE LOS HUECOS QUE PERMANECEN DESPUES DE QUE LA CAPA AISLANTE HA SIDO APLICADA SOBRE LOS DEVANADOS ROEBELADOS EN EL EXTERIOR DE LA BOBINA. LA ESTRUCTURA DE PARED PERFECCIONADA VENTAJOSAMENTE AUMENTA LA VIDA DE LAS BOBINAS DE ALTO VOLTAJE MEDIANTE LA REDUCCION DE LA CARGA ELECTRICA A TRAVES DE LA CAPA INTERIOR MOLDEADA, POR LO TANTO REDUCIENDO LA PROBABILIDAD DE DETERIORAMIENTO ELECTRICO DE ARCO NUNCA OCURRIRA EN NINGUNO DE LOS ESPACIOS HUECOS PRESENTES EN ESTA CAPA.
