<\/figure><\/div>\n\n\n\nDie Einstellung des Erdungsdrahtes f\u00fcr elektrische Betriebsmittel sollte je nach Gefahrenbereich und Art der elektrischen Betriebsmittel unterschiedlich gehandhabt werden. Die Metallgeh\u00e4use aller elektrischen Betriebsmittel in explosionsgef\u00e4hrdeten Bereichen sollten unabh\u00e4ngig davon, ob sie auf geerdeten Metallkonstruktionen installiert sind, geerdet sein. Die entsprechenden Anforderungen lauten wie folgt: <\/p>\n\n\n\n
1) Alle elektrischen Ger\u00e4te in explosionsgef\u00e4hrdeten Bereichen der Zone 1, Zone 20 und Zone 21 sowie alle elektrischen Ger\u00e4te mit Ausnahme von Beleuchtungsk\u00f6rpern in explosionsgef\u00e4hrdeten Bereichen der Zone 2 und Zone 22 sollten mit einem speziellen Erdungsdraht versehen werden. Hinweis: Wenn der spezielle Erdungsdraht im gleichen Schutzrohr wie der Phasendraht verlegt wird, sollte er die gleiche Isolierst\u00e4rke wie der Phasendraht haben. <\/p>\n\n\n\n
2) F\u00fcr Beleuchtungsk\u00f6rper in explosionsgef\u00e4hrdeten Umgebungen der Zone 2 und Zone 22 kann ein zuverl\u00e4ssiges elektrisches Verbindungs-Metallrohrsystem als Erdungsdraht verwendet werden, aber Rohrleitungen f\u00fcr den Transport von explosiven Gefahrstoffen k\u00f6nnen nicht verwendet werden. <\/p>\n\n\n\n
3) Die speziellen Erdungsdr\u00e4hte f\u00fcr elektrische Ger\u00e4te und Beleuchtungsk\u00f6rper sollten separat an das Erdungsnetz angeschlossen werden, und der funktionierende Nullleiter im Stromkreis sollte nicht als Schutzerdungsdraht verwendet werden. <\/p>\n\n\n\n
4) F\u00fcr die Verbindung zwischen elektrischen Ger\u00e4ten in explosionsgef\u00e4hrdeten Umgebungen und dem Erdungsdraht sollten vorzugsweise mehrdr\u00e4htige, flexible Litzen verwendet werden, wobei der Mindestquerschnitt des Kupferdrahtes 4 mm\u00b2 nicht unterschreiten sollte. An Teilen, die anf\u00e4llig f\u00fcr mechanische Besch\u00e4digungen sind, sollten Schutzrohre angebracht werden. <\/p>\n\n\n\n
5) Wenn gepanzerte Kabel in elektrische Ger\u00e4te eingef\u00fchrt werden, sollte der Erdungsdraht mit dem Erdungsbolzen im Inneren des Ger\u00e4ts verbunden werden; das Stahlband und das Metallgeh\u00e4use sollten mit dem \u00e4u\u00dferen Erdungsbolzen des Ger\u00e4ts verbunden werden. <\/p>\n\n\n\n
6) Die Schrauben, die f\u00fcr die Erdung oder den Nullanschluss in explosionsgef\u00e4hrdeten Umgebungen verwendet werden, sollten mit einer Lockerungsschutzvorrichtung versehen sein; vor dem Anziehen des Erdungsdrahtes sollten die Erdungsklemmen und Befestigungselemente mit einem Schmierfett bestrichen werden. <\/p>\n\n\n\n
Es gibt viele Anforderungen an die Erdung von elektrischen Ger\u00e4ten in explosionsgef\u00e4hrdeten Umgebungen. Bei der Konstruktion und Installation sollten neben den oben genannten Anforderungen auch die einschl\u00e4gigen Normen beachtet werden.<\/p>","protected":false},"excerpt":{"rendered":"
