Abstract

EN UN HORNO DE ARCO ELECTRICO DE CORRIENTE CONTINUA, EL ARCO ELECTRICO ES DESVIADO POR LA ACCION DE LOS CONDUCTORES DE ALTA INTENSIDAD (20) SITUADOS DEBAJO DEL RECIPIENTE DEL HORNO, EN DIRECCION AL DISPOSITIVO DE ALIMENTACION (12) DE CORRIENTE. ESTO CONDUCE A SOBRECARGAS TERMICAS EN UNA DE LAS PARTES DE LA PARED DEL RECIPIENTE DEL HORNO. SI SE INSTALAN LOS CONDUCTORES DE ALTA INTENSIDAD (18A) EN SU MAYOR PARTE EN UN PLANO POR ENCIMA DEL SUELO DEL HORNO O DEBAJO DE LA PLATAFORMA DEL HORNO (20), Y SE CONDUCEN PRIMERAMENTE EN LA PARTE OPUESTA AL DISPOSITIVO DE ALIMENTACION DEL RECIPIENTE DEL HORNO (1), HACIA ABAJO A LAS APARATOS DE CONEXION (10) EN EL SUELO DEL HORNO, ENTONCES EL ARCO ELECTRICO SE ENCIENDE DE NUEVO SIMETRICO.
