Abstract

La invención se refiere a un dispositivo de monitorización para fusibles eléctricos de seguridad, especialmente para fusibles de seguridad de altas prestaciones y bajo voltaje. Dicho dispositivo de monitorización se dispone en una red de corriente alterna polifásica, y tiene sensores de fase (2), cuyo terminal de entrada (3) está respectivamente conectado a un lado del fusible de seguridad (S1, S2, S3) que debe monitorizarse, y que emite una señal de salida que caracteriza la posición de fase de dicho voltaje cuando se dispone de una corriente alterna de red en sus terminales de entrada (3, 4). Las señales de salida de ambos sensores de fase (2), que están conectados a ambos lados de los fusibles de seguridad (S1, S2, S3) alimentan una etapa comparadora (6), que emite una señal que indica un "buen" estado de funcionamiento de los fusibles de seguridad en caso de coincidencia de fase, y una señal que indica "fallo" en caso de desequilibrio de fase. Dichas señales alimentan un dispositivo visor (10) y / o un ordenador (11).
