<\/a><\/figure><\/div>\n\n\n\nCe qui pr\u00e9c\u00e8de est la d\u00e9finition du type d'enrobage. En termes simples, il s'agit d'enfermer les sources d'inflammation possibles de mani\u00e8re \u00e0 ce qu'elles ne puissent pas s'enflammer dans des conditions normales de fonctionnement et de d\u00e9faillance. Les proc\u00e9d\u00e9s d'encapsulation les plus courants sont le moulage sous pression et le coulage. <\/p>\n\n\n\n
Pour les \u00e9quipements prot\u00e9g\u00e9s par un pot de type \u201cm\u201d, le compos\u00e9, la structure du pot, la temp\u00e9rature de l'\u00e9quipement, les essais et le marquage doivent \u00eatre pris en compte. <\/p>\n\n\n\n
1. Tenir compte du fabricant du compos\u00e9 utilis\u00e9 pour l'encapsulage, de la composition du mat\u00e9riau, du traitement de surface, de la temp\u00e9rature de fonctionnement continu (COT), de l'indice de r\u00e9sistance \u00e0 la chaleur \u00e0 long terme TI (lorsqu'il est utilis\u00e9 comme \u00e9l\u00e9ment du bo\u00eetier), de la rigidit\u00e9 di\u00e9lectrique de l'isolant et de l'absorption d'eau. <\/p>\n\n\n\n
2. La structure de l'enrobage doit tenir compte de la limite du volume net interne, des exigences d'\u00e9paisseur de l'enrobage en chaque point, de la limite de la valeur nominale des contacts internes de l'interrupteur, des exigences relatives aux batteries et aux blocs-batteries, de la protection des c\u00e2bles connect\u00e9s en permanence et des pi\u00e8ces sous tension expos\u00e9es, ainsi que de la d\u00e9termination et de la protection des d\u00e9faillances de l'\u00e9quipement. <\/p>\n\n\n\n
3. en fonctionnement normal et dans les conditions de d\u00e9faillance sp\u00e9cifi\u00e9es, la temp\u00e9rature maximale de la surface ne doit pas d\u00e9passer la valeur limite de la classe de temp\u00e9rature. Des dispositifs de protection doivent \u00eatre utilis\u00e9s pour limiter la temp\u00e9rature si n\u00e9cessaire. <\/p>\n\n\n\n
4. L'\u00e9quipement doit satisfaire aux exigences des essais de type et faire l'objet d'inspections et d'essais de routine selon les besoins. Des marquages doivent \u00eatre effectu\u00e9s sur l'\u00e9quipement selon les besoins.<\/p>","protected":false},"excerpt":{"rendered":"
