Title (EN) MONITORING AND RESPONDING TO AN ABNORMAL CONDITION ASSOCIATED WITH ENERGIZING OF POLES OF A CIRCUIT BREAKER
(FR) SURVEILLANCE ET RÉPONSE À UN ÉTAT ANORMAL ASSOCIÉ À L'EXCITATION DE PÔLES D'UN DISJONCTEUR
Abstract:
(EN) A multi-pole circuit interrupter (5) configured to be coupled between an AC source (15) and an electric load (20) electronically detects a hazardous condition associated with energizing of poles and responds to overcome the hazardous condition using a solenoid (900). The multi-pole circuit interrupter (5) comprises a first switch (25) to energize a first pole (30) on a phase A conductor (35) of the multi-pole circuit interrupter (5) and a second switch (40) to energize a second pole (45) on a phase B conductor (50) of the multi-pole circuit interrupter (5). The multi-pole circuit interrupter (5) further comprises an electronic solid-state circuit (10) coupled to the phase A conductor (35) and the phase B conductor (50) to detect a line voltage variation and control a current to a device (900) in response to trip an energized pole among the first pole (30) and the second pole (45) if only one of the first pole (30) and the second pole (45) is energized when a user controls a tie bar (205) to turn ON or turn OFF the multipole circuit interrupter (5) or when a trip bar (410) fails to trip one of the first pole (30) and the second pole (45).
(FR) La présente invention concerne un interrupteur de circuit multipolaire (5) conçu pour être couplé entre une source de courant alternatif (15) et une charge électrique (20) qui détecte électroniquement une condition dangereuse associée à l'excitation des pôles et répond pour surmonter l'état dangereux à l'aide d'une électrovanne (900). L'interrupteur de circuit multipolaire (5) comprend un premier commutateur (25) pour exciter un premier pôle (30) sur une phase d'un conducteur (35) de l'interrupteur de circuit multipolaire (5) et un second commutateur (40) pour exciter un second pôle (45) sur un conducteur de phase B (50) de l'interrupteur de circuit multipolaire (5). L'interrupteur de circuit multipolaire (5) comprend en outre un circuit électronique à semi-conducteurs (10) couplé à la phase a conducteur (35) et au conducteur de phase B (50) pour détecter une variation de tension de ligne et contrôler un courant vers un dispositif (900) en réponse à un déclenchement d'un pôle excité parmi le premier pôle (30) et le second pôle (45), si le premier pôle (30) ou le second pôle (45) est excité lorsqu'un utilisateur commande une tige de raccordement (205) pour allumer ou éteindre l'interrupteur de circuit multipolaire (5) ou lorsqu'une barre de déclenchement (410) tombe en panne pour déclencher le premier pôle (30) ou le second pôle (45).
