Abstract

UN DISPOSITIVO DE PROTECCION DIFERENCIAL CONSTA DE UN NUCLEO MAGNETICO (12) QUE LLEVA DOS ENROLLAMIENTOS SECUNDARIOS (14,16) CONECTADOS EN OPOSICION Y ALIMENTADOS DE FORMA ALTERNA POR UNA FUENTE DE CORRIENTE (22). UN CIRCUITO BIESTABLE (28) CONTROLA ALTERNATIVAMENTE LA EXCITACION DE LOS ENROLLAMIENTOS SECUNDARIOS (14,16) HASTA LA SATURACION DEL NUCLEO (12) DETECTADA POR UNA VARIACION BRUSCA DE LA CORRIENTE. UN DETECTOR (30) DE DERIVACION DE LA CORRIENTE EN RELACION AL TIEMPO EMITE UNA SEÑAL DE RELOJ DEL CIRCUITO BIESTABLE PARA DETENER LA EXCITACION DEL ARROLLAMIENTO SECUNDARIO CORRESPONDIENTE (14,16) AL SOBREPASARSE EL PUNTO DE SATURACION DEL NUCLEO (12). UNA SEÑAL DE FALLO DIFERENCIAL SE DETECTA POR COMPARACION DE LOS TIEMPOS DE EXCITACION DE LOS ARROLLAMIENTOS SECUNDARIOS (14,16).
