I. Aper\u00e7u du produit<\/strong><\/strong><\/h2>\n\n\n\n

Le coffret de contact de l'appareillage de commutation moyenne tension CH3-10Q\/150 630-1250A<\/a> adopte une structure de moulage par gel sous pression \u00e0 r\u00e9sine \u00e9poxy APG. C'est un dispositif de connexion isolante d\u00e9di\u00e9 pour la moyenne tension switchgear<\/a> et est principalement utilis\u00e9 dans les appareillages de commutation de type chariot \u00e0 main de niveau 10KV-12KV. Il joue un r\u00f4le d'isolation et de transition de connexion, et peut fournir une protection d'isolation efficace pour les contacts \u00e0 l'int\u00e9rieur de l'appareillage, assurant ainsi le fonctionnement s\u00fbr et stable du syst\u00e8me d'alimentation.<\/p>\n\n\n\n

III. Champ d'application<\/strong><\/strong><\/h2>\n\n\n\n

Ce bo\u00eetier de contact convient aux appareillages de commutation moyenne tension de type chariot \u00e0 main de niveau 10KV-12KV et est couramment utilis\u00e9 dans les syst\u00e8mes de distribution d'\u00e9nergie, les sous-stations industrielles, les salles de distribution d'\u00e9nergie des immeubles de grande hauteur, les syst\u00e8mes de distribution d'\u00e9nergie des entreprises industrielles et mini\u00e8res et d'autres installations \u00e9lectriques. Il sert de composant d'isolation et de transition de connexion pour les contacts internes de l'appareillage, offrant une protection d'isolation fiable pour la commutation et l'isolement des circuits haute tension.<\/p>\n\n\n\n

IV. Conditions d'utilisation<\/strong><\/strong><\/h2>\n\n\n\n

L'altitude \u00e0 laquelle l'installation est effectu\u00e9e ne doit pas d\u00e9passer 1000 m\u00e8tres.<\/p>\n\n\n\n

2. La temp\u00e9rature ambiante de l'air est de -10\u2103 \u00e0 +40\u2103, et l'humidit\u00e9 relative \u00e0 25\u2103 ne d\u00e9passe pas 95%.<\/p>\n\n\n\n

3. Le site d'installation doit \u00eatre exempt de gaz, vapeurs, poussi\u00e8res et autres milieux explosifs et corrosifs susceptibles d'affecter s\u00e9rieusement les performances d'isolation de la bo\u00eete de contact ;<\/p>\n\n\n\n

4. Il doit \u00eatre install\u00e9 dans un endroit exempt de vibrations et de chocs importants afin d'assurer la stabilit\u00e9 structurelle du produit.<\/p>\n\n\n\n

V. Caract\u00e9ristiques du produit<\/strong><\/strong><\/h2>\n\n\n\n

1.<\/strong> Excellente performance d'isolation<\/strong> Il est moul\u00e9 avec un proc\u00e9d\u00e9 de r\u00e9sine \u00e9poxy APG, qui offre de bonnes performances d'isolation, peut isoler efficacement les circuits haute tension, pr\u00e9venir les risques de fuite et de court-circuit, et r\u00e9sister aux chocs haute tension.<\/p>\n\n\n\n

2.<\/strong> Structure stable et durable<\/strong> La structure moul\u00e9e monobloc pr\u00e9sente une r\u00e9sistance m\u00e9canique \u00e9lev\u00e9e et peut supporter les contraintes m\u00e9caniques et \u00e9lectriques \u00e0 l'int\u00e9rieur de l'armoire de commutation, ce qui se traduit par une longue dur\u00e9e de vie.<\/p>\n\n\n\n

3.<\/strong> Bon contr\u00f4le de la mont\u00e9e en temp\u00e9rature<\/strong> En fonctionnement prolong\u00e9 sous courant nominal, l'\u00e9chauffement \u00e0 l'extr\u00e9mit\u00e9 de sortie ne d\u00e9passe pas 65\u2103, ce qui garantit efficacement le fonctionnement s\u00fbr de l'\u00e9quipement et \u00e9vite les d\u00e9faillances dues \u00e0 un \u00e9chauffement excessif.<\/p>\n\n\n\n

4.<\/strong> Installation facile<\/strong> Les dimensions d'installation standardis\u00e9es s'adaptent aux exigences d'installation des armoires de commande centrales conventionnelles, facilitant l'installation et le remplacement sur site.<\/p>\n\n\n\n

5.<\/strong> R\u00e9sistance \u00e0 la corrosion et \u00e0 l'oxydation<\/strong> La r\u00e9sine \u00e9poxy pr\u00e9sente une bonne r\u00e9sistance \u00e0 la corrosion et \u00e0 l'oxydation, et peut s'adapter \u00e0 divers environnements \u00e9lectriques complexes.<\/p>\n\n\n\n

6.<\/strong> Excellente finition de surface<\/strong> La surface est lisse et sans bavures, facile \u00e0 installer, et poss\u00e8de de bonnes propri\u00e9t\u00e9s ignifuges et r\u00e9sistantes \u00e0 l'usure.<\/p>\n\n\n\n
