Abstract

DISPOSITIVO ELECTRONICO DE SEGURIDAD, SIN COMPONENTES ELECTROMECANICOS, UTILIZABLE EN LA SEÑALIZACION DE FERROCARRILES. EL DISPOSITIVO ESTA CONTROLADO POR TRENES DE IMPULSOS (IA1, IB1) GENERADORES DE FORMA MUTUAMENTE INDEPENDIENTE, PARA PROPORCIONAR UNA CORRIENTE ALTERNA (IL1) A TRAVES DE UN BOBINADO (L1) SOLO DURANTE EL TIEMPO EN QUE SE PRODUCEN LOS TRENES DE IMPULSOS EN UNA PREDETERMINADA POSICION DE FASE EN RELACION ENTRE SI, Y MIENTRAS LOS COMPONENTES DEL DISPOSITIVO DE SEGURIDAD NO ESTAN DEFECTUOSOS. DOS DISPOSITIVOS CONMUTADORES (T1, T2) ESTAN DOTADOS DE ELECTRODOS DE CONTROL (A1, B2), ADAPTADOS CADA UNO PARA RECIBIR UN TREN DE IMPULSOS Y HACER ALTERNATIVAMENTE A LOS CONMUTADORES (T1, T2) CONDUCTORES Y NO CONDUCTORES. LA CORRIENTE INDUCIDA EN EL SECUNDARIO (L2) DEL TRANSFORMADOR (TR1) ACTUARA SOBRE LA LAMPARA DE SEÑALES (B1) O SOBRE ALGUN APARATO.
