\"Protecteur<\/p>\n

Protecteur limiteur de courant triphas\u00e9 4 fils JGFH-125JS<\/a>\u00a0 est un protecteur complet dot\u00e9 de diverses fonctions de protection telles que surtension, sous-tension, surintensit\u00e9, fuite, perte de phase et absence de z\u00e9ro. Le produit est modulaire, intelligent, visualis\u00e9, etc. et prend en charge le protocole de communication standard Modbus485, et tous les param\u00e8tres de protection tels que surtension<\/a>, La protection contre les surtensions, les sous-tensions et les surintensit\u00e9s peut \u00eatre r\u00e9gl\u00e9e en fonction de la demande de puissance, de mani\u00e8re \u00e0 garantir que les surtensions, les sous-tensions, les surintensit\u00e9s, les courants de fuite, les courts-circuits, les pertes de phase, etc. ne se produisent pas sur la ligne. En cas de d\u00e9faillance, telle que l'absence de z\u00e9ro, le protecteur peut couper instantan\u00e9ment l'alimentation \u00e9lectrique afin de prot\u00e9ger l'\u00e9quipement \u00e9lectrique contre les dommages.<\/p>\n

Conditions de travail<\/h2>\n
\n

1. Le premier d\u00e9lai normal de mise sous tension est de 20 secondes et se ferme automatiquement ; en cas de surtension, de sous-tension, de surintensit\u00e9 et de fuite lors de la premi\u00e8re mise sous tension, le produit sera automatiquement d\u00e9connect\u00e9 dans les 3 secondes ;<\/p>\n

2. La temp\u00e9rature ambiante ne d\u00e9passe pas +40 \u00b0C, n'est pas inf\u00e9rieure \u00e0 -5 \u00b0C et la temp\u00e9rature moyenne sur 24 heures ne d\u00e9passe pas +35 \u00b0C ; \u00e0 +40 \u00b0C, l'humidit\u00e9 de l'air ambiant ne d\u00e9passe pas 50%.<\/p>\n

3. La hauteur du cadran de la mer sur le site de l'installation ne doit pas d\u00e9passer 2000 m\u00e8tres.<\/p>\n

4. Niveau de pollution III.<\/p>\n

5. Dans l'environnement d'installation, il n'y a pas de risque d'explosion, pas de gaz corrosif et isolant ni de poussi\u00e8re conductrice, et pas d'invasion de pluie ou de neige.<\/p>\n
