Dans le secteur industriel mondial de l'\u00e9quipement \u00e9lectrique du march\u00e9, les transformateurs, comme les composants de base des syst\u00e8mes de puissance, ont vu leur niveau de protection devenue un facteur cl\u00e9 dans la s\u00e9lection des produits par les utilisateurs. Avec de plus en plus strictes normes de s\u00e9curit\u00e9 aupr\u00e8s d'organisations telles que la Commission \u00c9lectrotechnique Internationale (CEI) et de l'Institute of Electrical and Electronics Engineers (IEEE), l'optimisation du transformateur de conception de la structure \u00e0 renforcer la protection de la performance est devenue un d\u00e9fi majeur pour les fabricants et les ing\u00e9nieurs.

L'am\u00e9lioration de transformateur niveaux de protection est un g\u00e9nie des syst\u00e8mes d\u00e9fi impliquant de multiples domaines physiques. En appliquant la conception de la structure des m\u00e9thodes d\u00e9crites dans cet article, les fabricants peuvent \u00e9lever la protection du produit par 1-2 notes IP sans augmenter consid\u00e9rablement les co\u00fbts (environ 15-20%). Lors de la s\u00e9lection des transformateurs, les utilisateurs sont invit\u00e9s \u00e0 demander aupr\u00e8s de fournisseurs en plus des classiques param\u00e8tres:<\/p>\n
