LE CLIENT<\/h2>\n

Une entreprise italienne appartenant \u00e0 une grande multinationale fournissant des solutions d\u2019infrastructure int\u00e9gr\u00e9es pour l\u2019industrie ferroviaire mondiale, avec un besoin r\u00e9current de transformateurs d\u00e9di\u00e9s aux syst\u00e8mes UPS<\/a>.<\/p>\n

 <\/p>\n

LE BESOIN<\/h2>\n

Dans le ferroviaire, la continuit\u00e9 est une exigence de syst\u00e8me : toute anomalie peut impacter fiabilit\u00e9 et s\u00e9curit\u00e9. Les transformateurs UPS doivent respecter des exigences strictes : redresseurs 12 pulses, harmoniques (pertes\/\u00e9chauffement), Vcc%\/Xcc% impos\u00e9s, courants d\u2019appel et \u00e0 vide, encombrement contraint et conformit\u00e9 aux normes ferroviaires d\u00e9di\u00e9es. Le projet demandait aussi une coh\u00e9rence lot apr\u00e8s lot<\/strong> et des livraisons cadenc\u00e9es<\/strong>.<\/p>\n

 <\/p>\n

NOTRE SOLUTION<\/h2>\n

Ortea a mis en \u0153uvre une approche pilot\u00e9e par la sp\u00e9cification<\/strong>, avec calcul multi-physique<\/strong> (magn\u00e9tique + thermique + m\u00e9canique) et industrialisation orient\u00e9e vers la r\u00e9p\u00e9tabilit\u00e9 : ma\u00eetrise des imp\u00e9dances inter-enroulements et des fuites, choix noyau\/mat\u00e9riaux pour limiter pertes et temp\u00e9rature en pr\u00e9sence d\u2019harmoniques, layout et terminaux conformes aux contraintes d\u2019installation, v\u00e9rifications et essais reproductibles. La fourniture a \u00e9t\u00e9 organis\u00e9e via un programme annuel avec livraisons trimestrielles<\/strong>, garantissant continuit\u00e9 et homog\u00e9n\u00e9it\u00e9 des performances.<\/p>\n
