Protection de la distribution électrique

Présentation

Les unités de contrôle MicroLogic X sont conçues pour offrir une protection contre les surintensités et les courants de défaut de terre.

Description

Lorsque vous sélectionnez des caractéristiques de protection, prenez en compte les éléments suivants :

Surintensités (surcharges et courts-circuits) et défauts d’isolement potentiels
Conducteurs ayant besoin de protection
Coordination et sélectivité entre les appareils
Présence de courants harmoniques

Les caractéristiques de protection peuvent être représentées sur une courbe de déclenchement qui montre le temps de déclenchement du disjoncteur comme une fonction du courant mesuré et des paramètres de protection. Les paramètres de protection sont indexés sur le courant nominal In de l'unité de contrôle MicroLogic X.

Courant nominal In

Les plages de réglage des paramètres de protection dépendent du courant nominal In, défini par le calibreur inséré dans l'unité de contrôle MicroLogic X.

Le calibreur ne peut pas être remplacé ni modifié par l'utilisateur. Contactez votre technicien de maintenance Schneider Electric pour qu'il vérifie et remplace ou reconnecte le calibreur. Un détrompeur mécanique permet d'empêcher l'installation d'un calibreur non compatible avec le châssis du disjoncteur.

Le tableau suivant présente la gamme de calibreurs disponibles pour les disjoncteurs IEC.

Unité de contrôle MicroLogic 2.0 X

Les unités de contrôle MicroLogic 2.0 X IEC offrent :

Protection long retard contre les surintensités (Ir)
Protection instantanée contre les surintensités (Isd)

Les fonctions de protection des unités de contrôle MicroLogic 2.0 X fonctionnent sans alimentation auxiliaire. L'unité de contrôle est alimentée par le courant qui traverse le disjoncteur.

Les unités de contrôle MicroLogic 3.0 X UL offrent :

Protection long retard contre les surintensités (Ir)
Protection instantanée contre les surintensités (Ii)

Les fonctions de protection des unités de contrôle MicroLogic 3.0 X fonctionnent sans alimentation auxiliaire. L'unité de contrôle est alimentée par le courant qui traverse le disjoncteur.

Unité de contrôle MicroLogic 5.0 X

Les unités de contrôle MicroLogic 5.0 X IEC et UL offrent :

Protection long retard contre les surintensités (Ir)
Protection court retard contre les surintensités (Isd)
Protection instantanée contre les surintensités (Ii)

Les fonctions de protection des unités de contrôle MicroLogic 5.0 X fonctionnent sans alimentation auxiliaire. L'unité de contrôle est alimentée par le courant qui traverse le disjoncteur.

Unité de contrôle MicroLogic 6.0 X

Les unités de contrôle MicroLogic 6.0 X IEC et UL offrent :

Protection long retard contre les surintensités (Ir)
Protection court retard contre les surintensités (Isd)
Protection instantanée contre les surintensités (Ii)
Protection contre les défauts à la terre (Ig)

Les fonctions de protection des unités de contrôle MicroLogic 6.0 X fonctionnent sans alimentation auxiliaire. L'unité de contrôle est alimentée par le courant qui traverse le disjoncteur.

Unité de contrôle MicroLogic 7.0 X

Les unités de contrôle MicroLogic 7.0 X IEC offrent :

Protection long retard contre les surintensités (Ir)
Protection court retard contre les surintensités (Isd)
Protection instantanée contre les surintensités (Ii)
Protection différentielle (IΔn)

Les fonctions de protection des unités de contrôle MicroLogic 7.0 X fonctionnent sans alimentation auxiliaire externe.

L'unité de contrôle MicroLogic X est alimentée par le courant qui traverse le disjoncteur. Un module d'alimentation de tension VPS est également requis pour assurer la protection différentielle avec un courant de défaut de très faible valeur.

Protections instantanées DIN / DINF et SELLIM

Les protections instantanées DIN / DINF et SELLIM sont des protections internes utilisées lorsque le courant de court-circuit atteint la limite de résistance du disjoncteur. Ces protections ne sont pas réglables et ne se déclenchent généralement pas dans des conditions normales de fonctionnement.

Les événements prédéfinis suivants peuvent être générés par les protections instantanées DIN / DINF et SELLIM.

Code	Evénement	Historique	Sévérité
0x6406 (25606)	Déclenchement auto-protection ultime (SELLIM)	Déclenchement	Haute
0x641D (25629)	Déclenchement auto-protection ultime (DIN/DINF)	Déclenchement	Haute
0x6306 (25350)	Ordre de déclenchement auto-protection ultime (SELLIM)	Protection	Moyenne
0x631D (25373)	Ordre de déclenchement auto-protection ultime (DIN/DINF)	Protection	Moyenne

Les événements prédéfinis ne peuvent pas être modifiés par l'utilisateur. Pour des informations générales sur les événements, reportez-vous à la section Gestion des événements.

Actions recommandées

Code	Événement	Actions recommandées
0x6406 (25606)	Déclenchement auto-protection ultime (SELLIM)	Réinitialisez l'appareil ou utilisez l'Assistant analyse de défaut de Application EcoStruxure Power Device.
