<\/figure><\/div>\n\n\n\nIndstillingerne for jordforbindelse til elektrisk udstyr skal behandles forskelligt i henhold til forskellige farlige omr\u00e5der og typer af elektrisk udstyr. Metalkabinetterne p\u00e5 alt elektrisk udstyr i eksplosive milj\u00f8er skal jordes, uanset om de er installeret p\u00e5 jordede metalkonstruktioner. De relevante krav er som f\u00f8lger: <\/p>\n\n\n\n
1) Alt elektrisk udstyr i eksplosive milj\u00f8er i Zone 1, Zone 20 og Zone 21 samt alt elektrisk udstyr undtagen belysningsarmaturer i eksplosive milj\u00f8er i Zone 2 og Zone 22 skal have tilf\u00f8jet dedikerede jordledninger. Bem\u00e6rk: Hvis den dedikerede jordledning l\u00e6gges i samme beskyttelsesr\u00f8r som faseledningen, skal den have samme isoleringsniveau som faseledningen. <\/p>\n\n\n\n
2) Til belysningsarmaturer i eksplosive milj\u00f8er i Zone 2 og Zone 22 kan et p\u00e5lideligt elektrisk forbindelsesmetalr\u00f8rsystem bruges som jordledning, men r\u00f8rledninger til transport af eksplosive farlige stoffer kan ikke bruges. <\/p>\n\n\n\n
3) De dedikerede jordledninger til elektrisk udstyr og belysningsarmaturer skal forbindes separat til jordledningen (netv\u00e6rket), og den fungerende neutrale ledning i det elektriske kredsl\u00f8b b\u00f8r ikke bruges som beskyttende jordledning. <\/p>\n\n\n\n
4) Forbindelsen mellem elektrisk udstyr i eksplosionsfarlige milj\u00f8er og jordledningen skal helst bruge flerstrenget, fleksibel, snoet ledning med et minimumstv\u00e6rsnitsareal af kobbertr\u00e5d p\u00e5 mindst 4 mm\u00b2. Beskyttelsesr\u00f8r skal installeres p\u00e5 dele, der er udsat for mekaniske skader. <\/p>\n\n\n\n
5) N\u00e5r pansrede kabler f\u00f8res ind i elektrisk udstyr, skal jordforbindelsesledningen forbindes til jordforbindelsesbolten inde i udstyret; st\u00e5lb\u00e5ndet og metalkabinettet skal forbindes til udstyrets eksterne jordforbindelsesbolt. <\/p>\n\n\n\n
6) De bolte, der bruges til jordforbindelse eller nulforbindelse i eksplosionsfarlige milj\u00f8er, skal have antil\u00f8sningsanordninger; f\u00f8r jordledningen strammes, skal jordforbindelsesterminalerne og fastg\u00f8relseselementerne overtr\u00e6kkes med str\u00f8mforbindelsesfedt. <\/p>\n\n\n\n
Der er mange krav til jordforbindelse for elektrisk udstyr i eksplosionsfarlige milj\u00f8er. I design- og installationsprocessen skal man ud over at opfylde ovenst\u00e5ende krav ogs\u00e5 f\u00f8lge relevante standarder.<\/p>","protected":false},"excerpt":{"rendered":"
