<\/figure><\/div>\n\n\n\nLes r\u00e9glages du c\u00e2ble de mise \u00e0 la terre pour le mat\u00e9riel \u00e9lectrique doivent \u00eatre trait\u00e9s diff\u00e9remment selon les zones dangereuses et les types de mat\u00e9riel \u00e9lectrique. Les enveloppes m\u00e9talliques de tous les mat\u00e9riels \u00e9lectriques utilis\u00e9s dans des environnements explosifs doivent \u00eatre mises \u00e0 la terre, qu'elles soient ou non install\u00e9es sur des structures m\u00e9talliques mises \u00e0 la terre. Les exigences correspondantes sont les suivantes : <\/p>\n\n\n\n
1) Tous les \u00e9quipements \u00e9lectriques dans les environnements explosifs des zones 1, 20 et 21, ainsi que tous les \u00e9quipements \u00e9lectriques \u00e0 l'exception des appareils d'\u00e9clairage dans les environnements explosifs des zones 2 et 22, doivent \u00eatre \u00e9quip\u00e9s de fils de mise \u00e0 la terre d\u00e9di\u00e9s. Note : Si le fil de mise \u00e0 la terre est plac\u00e9 dans le m\u00eame conduit de protection que le fil de phase, il doit avoir le m\u00eame niveau d'isolation que le fil de phase. <\/p>\n\n\n\n
2) Pour les appareils d'\u00e9clairage dans les environnements explosifs des zones 2 et 22, un syst\u00e8me de tuyauterie m\u00e9tallique \u00e0 connexion \u00e9lectrique fiable peut \u00eatre utilis\u00e9 comme fil de mise \u00e0 la terre, mais les tuyauteries pour le transport de substances dangereuses explosives ne peuvent pas \u00eatre utilis\u00e9es. <\/p>\n\n\n\n
3) Les fils de mise \u00e0 la terre d\u00e9di\u00e9s \u00e0 l'\u00e9quipement \u00e9lectrique et aux appareils d'\u00e9clairage doivent \u00eatre connect\u00e9s s\u00e9par\u00e9ment au r\u00e9seau principal de mise \u00e0 la terre, et le fil neutre du circuit \u00e9lectrique ne doit pas \u00eatre utilis\u00e9 comme fil de mise \u00e0 la terre de protection. <\/p>\n\n\n\n
4) La connexion entre le mat\u00e9riel \u00e9lectrique dans des environnements explosifs dangereux et le fil de mise \u00e0 la terre doit de pr\u00e9f\u00e9rence utiliser des fils multibrins flexibles, la section minimale du fil de cuivre n'\u00e9tant pas inf\u00e9rieure \u00e0 4 mm\u00b2. Des tubes protecteurs doivent \u00eatre install\u00e9s sur les parties susceptibles d'\u00eatre endommag\u00e9es m\u00e9caniquement. <\/p>\n\n\n\n
5) Lorsque des c\u00e2bles arm\u00e9s sont introduits dans un \u00e9quipement \u00e9lectrique, le fil de mise \u00e0 la terre doit \u00eatre connect\u00e9 au boulon de mise \u00e0 la terre \u00e0 l'int\u00e9rieur de l'\u00e9quipement ; le ruban d'acier et l'enveloppe m\u00e9tallique doivent \u00eatre connect\u00e9s au boulon de mise \u00e0 la terre externe de l'\u00e9quipement. <\/p>\n\n\n\n
6) Les boulons utilis\u00e9s pour la mise \u00e0 la terre ou la connexion z\u00e9ro dans les environnements explosifs dangereux doivent \u00eatre munis de dispositifs anti-desserrage ; avant de serrer le fil de mise \u00e0 la terre, les bornes de mise \u00e0 la terre et les fixations doivent \u00eatre enduites de graisse pour composants de puissance. <\/p>\n\n\n\n
Il existe de nombreuses exigences en mati\u00e8re de mise \u00e0 la terre pour les \u00e9quipements \u00e9lectriques dans les environnements explosifs dangereux. Lors de la conception et de l'installation, il convient de respecter non seulement les exigences susmentionn\u00e9es, mais aussi les normes pertinentes.<\/p>","protected":false},"excerpt":{"rendered":"
