Die dielektrische Isolationsfestigkeit von elektrischen Betriebsmitteln des Typs \u201cn\u201d gegen Erde oder Rahmen muss den folgenden Bestimmungen entsprechen, es sei denn, die in den elektrischen Betriebsmitteln installierten Stromkreise sind direkt mit dem Rahmen des Betriebsmittels verbunden oder w\u00e4hrend des Betriebs des Betriebsmittels mit dem Rahmen verbunden: <\/p>\n\n\n\n

a. Pr\u00fcfungen, wie sie in den einschl\u00e4gigen Industrienormen f\u00fcr die verschiedenen Bauteile elektrischer Betriebsmittel festgelegt sind, oder <\/p>\n\n\n\n

b. Bestehen die oben genannten Pr\u00fcfanforderungen nicht, so muss zumindest die Pr\u00fcfspannung den folgenden Anforderungen 1) oder 2) entsprechen und darf mindestens 1 Minute lang nicht zusammenbrechen. <\/p>\n\n\n\n

1) Bei elektrischen Betriebsmitteln mit einer Spitzenversorgungsspannung von h\u00f6chstens 90 V oder einer internen Spitzenspannung von h\u00f6chstens 90 V betr\u00e4gt der Effektivwert der Pr\u00fcfspannung 500 V; <\/p>\n\n\n\n

2) Bei anderen elektrischen Betriebsmitteln oder Betriebsmitteln mit einer internen Spitzenspannung von mehr als 90 V ist der Effektivwert der Pr\u00fcfspannung der gr\u00f6\u00dfere Wert von 2 U + 1000 V oder 1500 V.<\/p>\n\n\n\n

Es ist zul\u00e4ssig, anstelle der angegebenen Pr\u00fcfwechselspannung eine Pr\u00fcfgleichspannung zu verwenden. F\u00fcr isolierte Wicklungen sollte sie 170% des Effektivwerts der angegebenen Pr\u00fcfwechselspannung betragen, oder f\u00fcr die elektrische Luft- oder Kriechstrecke im Isoliermedium sollte sie 140% des Effektivwerts der angegebenen Pr\u00fcfwechselspannung betragen. <\/p>\n\n\n\n

Hinweis: U ist der h\u00f6here Wert der Nennversorgungsspannung oder der h\u00f6chsten Spannung, die im Inneren des Ger\u00e4ts auftritt. <\/p>\n\n\n\n

Bei Ger\u00e4ten mit elektrisch isolierten Bauteilen sollte die Pr\u00fcfspannung an jedes Bauteil separat mit der entsprechenden Spannung angelegt werden.<\/p>","protected":false},"excerpt":{"rendered":"
