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, de niveau 10 kV-12 kV. Il est couramment utilis\u00e9 dans les installations \u00e9lectriques n\u00e9cessitant une transmission de courant ultra-\u00e9lev\u00e9, telles que les grands syst\u00e8mes de distribution d'\u00e9nergie, les sous-stations industrielles, les syst\u00e8mes de distribution d'\u00e9nergie des grandes entreprises industrielles et mini\u00e8res, et les grandes centrales hydro\u00e9lectriques. En tant que composant de protection d'isolation et de transition de connexion pour les contacts internes de l'appareillage, il offre une protection d'isolation fiable pour la commutation et l'isolement des circuits haute tension et convient aux exigences de transmission d'\u00e9nergie \u00e0 courant ultra-\u00e9lev\u00e9.<\/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 de l'air ambiant est de -5\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

5. Convient \u00e0 une installation int\u00e9rieure et compatible avec une installation de branche \u00e0 grande \u00e9chelle.<\/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> Adaptabilit\u00e9 \u00e0 fort courant<\/strong> Le courant nominal peut atteindre 3150A, ce qui r\u00e9pond aux exigences de transmission de courant \u00e9lev\u00e9 des grandes installations \u00e9lectriques et r\u00e9duit les pertes de chaleur.<\/p>\n\n\n\n
