Quelles Sont Les Particularit\u00e9s Des Mod\u00e8les Doit L'\u00c9preuve Du Feu De Transformateurs De R\u00e9pondre?<\/h1>\n

\u2014Certifi\u00e9 UL Mat\u00e9riau ininflammable Exigences<\/h4>\n

Dans le contexte de plus en plus strictes normes de s\u00e9curit\u00e9 globales pour l'\u00e9quipement \u00e9lectrique, l'\u00e9preuve du feu de transformateurs sont devenus essentiels des dispositifs de s\u00e9curit\u00e9 dans les secteurs industriel, commercial et r\u00e9sidentiel, syst\u00e8mes d'alimentation. Ces transformateurs doivent non seulement r\u00e9pondre de base \u00e9lectrique exigences de performance, mais aussi de se conformer avec le retardateur de flamme d'essai de mat\u00e9riau de normes \u00e9tablies par des organismes de certification internationaux tels que l'UL (Underwriters Laboratories). Cet article fournit une analyse d\u00e9taill\u00e9e de la conception sp\u00e9ciale, la s\u00e9lection des mat\u00e9riaux, et des exigences de certification pour l'\u00e9preuve du feu transformateurs.<\/p>\n

1. Pourquoi Ne L'\u00c9preuve Du Feu De Transformateurs N\u00e9cessitent Des Mod\u00e8les Sp\u00e9ciaux?<\/em><\/b><\/h3>\n

Les transformateurs peuvent surchauffer et prendre feu en raison de la dur\u00e9e prolong\u00e9e de la surcharge, l'isolation de vieillissement, ou de court-circuit des d\u00e9fauts. Selon les statistiques de la National Fire Protection Association (NFPA), \u00e9quipements \u00e9lectriques, les \u00e9checs sont une des principales causes d'incendies industriels. Par cons\u00e9quent, la conception de l'\u00e9preuve du feu de transformateurs ne doivent pas seulement se concentrer sur l'efficacit\u00e9 et la stabilit\u00e9, mais aussi int\u00e9grer des mat\u00e9riaux ignifuges et des structures sp\u00e9cialis\u00e9es afin de ralentir la propagation du feu. Cela garantit le transformateur peut continuer \u00e0 fonctionner pendant un temps limit\u00e9 et dans des conditions extr\u00eames, en fournissant de temps pour l'\u00e9vacuation et l'intervention d'urgence.<\/p>\n

2. La cl\u00e9 des Exigences de Conception pour l'\u00e9preuve du feu Transformateurs<\/em><\/b><\/h3>\n

2.1 Certifi\u00e9 UL Retardateur de Flamme de Mat\u00e9riaux d'Isolation<\/strong><\/h4>\n

L'une des principales exigences de s\u00e9curit\u00e9 pour l'\u00e9preuve du feu transformateurs est que leurs mat\u00e9riaux d'isolation doivent \u00eatre conformes avec le retardateur de flamme des normes telles que la norme UL 94 et UL 1446.<\/p>\n

2.1.1 UL 94 Standard: Classification d'Inflammabilit\u00e9 des Mat\u00e9riaux Plastiques<\/strong><\/h5>\n
(1) UL 94 est la cl\u00e9 pour l'\u00e9valuation de l'ignifuges les propri\u00e9t\u00e9s des mat\u00e9riaux en plastique. Les couches d'isolant, des bo\u00eetiers, des internes et des structures de soutien de l'\u00e9preuve du feu de transformateurs g\u00e9n\u00e9ralement la n\u00e9cessit\u00e9 de parvenir \u00e0 un V-0 ou V-1 cote.<\/strong><\/h6>\n\n\n\n\n\n\n
UL 94 Notation<\/b><\/td>\nLe Temps De Combustion<\/b><\/td>\nD\u00e9goulinant De S'Enflamme Coton?<\/b><\/td>\nLes Sc\u00e9narios D'Application<\/b><\/td>\n<\/tr>\n
V-0<\/td>\n\u226410 secondes<\/td>\nPas de<\/td>\nDes environnements \u00e0 haut risque (par exemple, les usines chimiques, les centres de donn\u00e9es)<\/td>\n<\/tr>\n
V-1<\/td>\n\u226430 secondes<\/td>\nPas de<\/td>\nG\u00e9n\u00e9rale de l'utilisation industrielle<\/td>\n<\/tr>\n
V-2<\/td>\n\u226430 secondes<\/td>\nOui<\/td>\nFaible risque d'applications<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
(2) Pourquoi UL 94 V-0 de Mat\u00e9riaux plus S\u00fbrs?<\/strong><\/h6>\n

V-0-nominale mat\u00e9riaux auto-\u00e9teindre dans les 10 secondes apr\u00e8s retrait de la flamme, et leur fusion, les gouttelettes ne pas s'enflammer les mat\u00e9riaux inflammables ci-dessous. Par exemple, un transformateur de bo\u00eetiers faite de polyamide (PA) ou le retardateur de flamme en polycarbonate (FR-PC) peut r\u00e9duire de fa\u00e7on significative les risques d'incendie.<\/p>\n

2.1.2 UL 1446: la Temp\u00e9rature et de R\u00e9sistance \u00e0 la Flamme des Exigences pour les Syst\u00e8mes d'Isolation<\/strong><\/h5>\n

UL 1446 sp\u00e9cifie la r\u00e9sistance de la temp\u00e9rature de notes, pour le transformateur d'isolation des syst\u00e8mes (par exemple, la Classe A: 105\u00b0C, Classe H: 180\u00b0C). L'\u00e9preuve du feu de transformateurs n\u00e9cessitent g\u00e9n\u00e9ralement de Classe F (155\u00b0C) ou plus des syst\u00e8mes d'isolation pour s'assurer que le mat\u00e9riel ne se d\u00e9composent pas et la lib\u00e9ration de gaz inflammables sous des conditions de surcharge.<\/p>\n

2.2 Arc-R\u00e9sistant et Clos de Conception Structurelle<\/strong><\/h4>\n

L'\u00e9preuve du feu de transformateurs doivent passer des tests de r\u00e9sistance \u00e0 l'arc en vertu de normes telles que UL 506 (Norme de S\u00e9curit\u00e9 pour les Transformateurs) ou de la CEI 60076-11 (Protection Incendie Standard pour les Transformateurs \u00e0 Sec). Caract\u00e9ristiques principales incluent:<\/p>\n

(1) R\u00e9sine \u00c9poxy De Coul\u00e9e Sous Vide De Processus:<\/strong><\/h6>\n

Haute tension des bobines de vide-impr\u00e9gn\u00e9s avec de la r\u00e9sine \u00e9poxy durci pour former une dense couche d'isolation, la pr\u00e9vention de l'arc de rupture. L'indice d'oxyg\u00e8ne (LOI) de la r\u00e9sine d'\u00e9poxy doit \u00eatre \u2265\u00e0 28% (LI >26% est consid\u00e9r\u00e9 comme retardateur de flamme).<\/p>\n

\"17\"<\/a><\/p>\n

(2) Blindage M\u00e9tallique Laye<\/strong>r:<\/h6>\n

En aluminium ou en aluminium d'en cuivre de boucliers sont ajout\u00e9s entre haute et basse tension enroulements \u00e0 r\u00e9duire la d\u00e9gradation de l'isolant caus\u00e9 par une d\u00e9charge partielle.<\/p>\n

Formule:Relation Entre l'Indice d'Oxyg\u00e8ne (LOI) et de la r\u00e9sistance \u00e0 la Flamme<\/p>\n

LI = (Volume d'Oxyg\u00e8ne \/ (Volume d'Oxyg\u00e8ne + Azote Volume)) \u00d7 100%<\/strong><\/p>\n

Plus LOI indique plus forte autonomie-moyens d'extinction en cas d'incendie.<\/p>\n

Par exemple, ordinaire poly\u00e9thyl\u00e8ne a une LOI de 17%, tandis que le retardateur de flamme-r\u00e9sine \u00e9poxyde modifi\u00e9e peut atteindre une LETTRE d'intention de plus de 30%.<\/p>\n

2.3 Dissipation de la Chaleur et de Protection de Surcharge de Coordination<\/strong><\/h4>\n

L'\u00e9preuve du feu de transformateurs doivent \u00e9quilibrer le conflit entre les “la r\u00e9sistance \u00e0 la flamme”, et “la dissipation de la chaleur”:<\/p>\n

(1)Syst\u00e8me De Refroidissement \u00c0 Air Forc\u00e9:\u00a0<\/strong><\/h6>\n

Utilise class\u00e9 IP54, retardateur de flamme de fans (conforme \u00e0 la norme UL 507) pour am\u00e9liorer la dissipation de la chaleur. Les moteurs des ventilateurs doit \u00e9galement \u00eatre certifi\u00e9 UL 1004-1.<\/p>\n

(2) Bim\u00e9tallique De La Temp\u00e9rature Protecteur:<\/strong><\/h6>\n

Automatiquement la coupure du circuit lors du remontage des temp\u00e9ratures d\u00e9passent seuil s\u00e9curitaire. Son actionnement de temp\u00e9rature pr\u00e9cision de temp\u00e9rature doit r\u00e9pondre UL 1434 normes.<\/p>\n

3. Comment Choisir la conformit\u00e9 de l'\u00e9preuve du feu de Transformateur?<\/em><\/b><\/h3>\n
(1)V\u00e9rifier Les Marques De Certification: <\/strong><\/h6>\n

V\u00e9rifier si le produit est \u00e9tiquet\u00e9 avec la liste UL et CEI num\u00e9ros de certification.<\/p>\n

(2)Fiche de Donn\u00e9es de S\u00e9curit\u00e9 (FS):<\/strong><\/h6>\n

Demander au fournisseur de fournir de l'UL Carte Jaune pour les mat\u00e9riaux d'isolation pour confirmer retardateur de flamme de cotes.<\/p>\n

(3)Correspondent \u00c0 Des Sc\u00e9narios D'Application:<\/strong><\/h6>\n

Environnements \u00e0 haut risque, comme les usines chimiques ou dans les tunnels devraient opter pour des transformateurs avec UL 94 V-0 + Classe H d'isolation.<\/p>\n
