Abstract

Disyuntor de circuito (100) para proteger un sistema eléctrico (10) que comprende una línea de alimentación de red (LIN) de corriente alterna, por lo menos uno carga eléctrica (LD) y el disyuntor de circuito (100), comprendiendo dicho disyuntor: - un elemento de conmutación de semiconductor (T1) que tiene un terminal eléctrico primero (1) y uno segundo (2) conectados a la línea de alimentación de red (LIN) y un terminal de control (3), estando controlado dicho elemento de conmutación (T1) mediante la activación/desactivación de una señal de control (S) aplicada al terminal de control (3) para conmutar entre un estado abierto/cerrado y un estado cerrado/abierto para conectar/desconectar por lo menos una carga (LD) a/de dicha línea de alimentación (LIN), - un excitador (DV) adaptado para activar/desactivar dichas señales de control (S), - un circuito de limitación de corriente (200) asociado operativamente con la línea de alimentación de red (LIN) configurado para enviar una primera señal (S1) a dicho excitador (DV) para desactivar dicha señal de control (S) conmutando el elemento de conmutación (T1) del estado cerrado al estado abierto subsiguientemente a la detección de un valor de corriente (Icc) indicativo de un fallo en el sistema, - un circuito regulador de tensión (300, 400) conectado a dicho terminal eléctrico primero (1) y segundo (2) del elemento de conmutación (T1); caracterizado porque el circuito regulador de tensión (300, 400) comprende: medios de disipación (300) de una energía eléctrica residual almacenada en la línea de alimentación de red (LIN) subsiguientemente a la conmutación del elemento de conmutación (T1) del estado cerrado al estado abierto debido a la detección de dicha corriente de fallo (Icc), medios (400) para detectar una tensión de fallo entre dicho terminal primero (1) y segundo (2) generada por valores de pico de la corriente de fallo (Icc) en dicha conmutación del elemento de conmutación (T1) del estado cerrado al estado abierto, en donde dichos medios de detección (400) se configuran para enviar una segunda señal (S6) a dicho excitador (DV) para mantener dicha señal de control (S) desactivada.
