<\/figure><\/div>\n\n\n\nDe aarddraadinstellingen voor elektrische apparatuur moeten verschillend worden behandeld naargelang de verschillende gevaarlijke gebieden en soorten elektrische apparatuur. De metalen behuizingen van alle elektrische apparatuur in explosieve omgevingen, ongeacht of ze zijn ge\u00efnstalleerd op geaarde metalen constructies, moeten worden geaard. De relevante vereisten zijn als volgt: <\/p>\n\n\n\n
1) Alle elektrische apparatuur in explosiegevaarlijke omgevingen Zone 1, Zone 20 en Zone 21, en alle elektrische apparatuur behalve verlichtingsarmaturen in explosiegevaarlijke omgevingen Zone 2 en Zone 22, moeten worden voorzien van speciale aardingsdraden. N. B.: Als de speciale aardingsdraad in dezelfde beschermende leiding wordt gelegd als de fasedraad, moet deze hetzelfde isolatieniveau hebben als de fasedraad. <\/p>\n\n\n\n
2) Voor verlichtingsarmaturen in explosiegevaarlijke omgevingen Zone 2 en Zone 22 kan een betrouwbaar elektrisch verbindingsmetalen leidingsysteem worden gebruikt als aardingsdraad, maar leidingen voor het transport van explosieve gevaarlijke stoffen kunnen niet worden gebruikt. <\/p>\n\n\n\n
3) De speciale aardingsdraden voor elektrische apparatuur en verlichtingsarmaturen moeten apart worden aangesloten op het aardingshoofdnet en de werkende neutrale draad in het elektrische circuit mag niet worden gebruikt als beschermende aardingsdraad. <\/p>\n\n\n\n
4) Voor de verbinding tussen elektrische apparatuur in explosiegevaarlijke omgevingen en de aardingsdraad moet bij voorkeur meeraderige flexibele gevlochten draad worden gebruikt, met een minimale doorsnede van koperdraad van 4 mm\u00b2. Beschermbuizen moeten worden ge\u00efnstalleerd bij onderdelen die gevoelig zijn voor mechanische schade. <\/p>\n\n\n\n
5) Wanneer gepantserde kabels in elektrische apparatuur worden ingevoerd, moet de aardingsdraad worden aangesloten op de aardingsbout in de apparatuur; de staalband en metalen behuizing moeten worden aangesloten op de externe aardingsbout van de apparatuur. <\/p>\n\n\n\n
6) De bouten die worden gebruikt voor aarding of nulverbinding in explosiegevaarlijke omgevingen moeten zijn voorzien van een beveiliging tegen losdraaien; voordat de aardingsdraad wordt vastgedraaid, moeten de aardingsklemmen en bevestigingsmiddelen worden ingesmeerd met vet van een stroomcompound. <\/p>\n\n\n\n
Er zijn veel aardingsvereisten voor elektrische apparatuur in explosiegevaarlijke omgevingen. In het ontwerp- en installatieproces moeten, naast het voldoen aan de bovenstaande vereisten, ook de relevante normen worden gevolgd.<\/p>","protected":false},"excerpt":{"rendered":"
