Abstract

Un arreglo interruptor de circuito auto-energizado para interrumpir corriente en una trayectoria de circuito usa un componente de bloqueo de corriente para asegurar que una cantidad insuficiente de energía acumulada para accionar la interrupcion de la trayectoria de circuito no sea malgastada en un intento injustificado por interrumpir la trayectoria de corriente. El arreglo incluye un circuito inductor de corriente para proporcionar una señal de corriente que tiene una magnitud correspondiente a la corriente en la trayectoria de circuito; una fuente de energía que opera a partir de la señal de corriente provista por el inductor de corriente y proporcionando una señal de voltaje de un valor predeterminado con relacion al comun; un mecanismo de solenoide que tiene una bobina a través de la cual pasa corriente desde la fuente de energía para ocasionar interrupcion de la corriente en la trayectoria de circuito; un circuito de comando de disparo, que responde a una falla en la trayectoria de circuito e incluyendo un detector de sobrecarga, para enviar una señal eléctrica que ordena que la trayectoria de circuito sea interrumpida; un cerrojo eléctrico accionado en respuesta tanto a la señal eléctrica del circuito de comando de disparo como la señal de voltaje que excede un valor predeterminado, el cerrojo eléctrico dispuesto en serie con la bobina entre la fuente de energía y el comun e incluyendo una primera terminal acoplada al circuito de comando de disparo y una segunda terminal acoplada a la fuente de energía; y un circuito de prevencion construido y dispuesto para impedir que una señal eléctrica del circuito de comando de disparo o la señal de voltaje vincule el cerrojo eléctrico hasta que la señal de voltaje excede el valor predeterminado. También se describen diversos arreglos alternativos para superar los problemas de la auto-energizacion de un interruptor de circuito.
