Lichtbogenabschreckung Medium<\/strong><\/strong><\/h2>\n\n\n\n

Luftstromunterbrecher (ACB): Im Falle eines Fehlers oder beim Ausschalten ist das Medium zum L\u00f6schen des Lichtbogens Luft mit atmosph\u00e4rischem Druck. Der Lichtbogen k\u00fchlt durch die ihn umgebende Luft ab.<\/p>\n\n\n\n

Vakuum-Leitungsschutzschalter (VCB): Bei dieser Art von Leistungsschalter wird ein Hochvakuum als Medium zur Lichtbogenl\u00f6schung verwendet. Ein Lichtbogen wird in einer Vakuumkammer gel\u00f6scht, in der das Fehlen von Partikeln eine schnelle Lichtbogenunterdr\u00fcckung erm\u00f6glicht.<\/p>\n\n\n\n

Lichtbogenabschreckung<\/strong><\/strong><\/h2>\n\n\n\n

ACB: Verlassen sich auf Luftblasen oder magnetisches Blasen zur Verl\u00e4ngerung und K\u00fchlung des Lichtbogens. In der Regel ist es auch mit Metallkontakten und Lichtbogenkan\u00e4len ausgestattet, um den Lichtbogen zu f\u00fchren und die Lichtbogenenergie zu kontrollieren.<\/p>\n\n\n\n

VCB: Wenn sich die Kontakte \u00f6ffnen, bildet sich ein kleiner Lichtbogen. Dieser Lichtbogen wird im Vakuum durch die Kondensation des Metalldampfes schnell gel\u00f6scht, was zum schnellen Erl\u00f6schen des Lichtbogens ohne zus\u00e4tzliche K\u00fchlmechanismen beitr\u00e4gt.<\/p>\n\n\n\n

Anwendungen<\/strong><\/strong><\/h2>\n\n\n\n

ACBs: Sie sind in der Regel f\u00fcr Niederspannungsanwendungen gedacht, in der Regel bis etwa 1 kV, und werden daher in Gewerbe- und Industriegeb\u00e4uden, Schalttafeln und anderen Niederspannungsanlagen eingesetzt.<\/p>\n\n\n\n

VCB: Diese werden haupts\u00e4chlich bei mittleren Spannungen bis zu 36 kV oder h\u00f6her eingesetzt. Sie sind sehr gut geeignet f\u00fcr Umspannwerke, Industrieanlagen und kritische Systeme, die eine zuverl\u00e4ssige Lichtbogenunterbrechung erfordern.<\/p>\n\n\n\n

Wartung<\/strong><\/strong><\/h2>\n\n\n\n

ACB: Die Wartung muss h\u00e4ufiger durchgef\u00fchrt werden, da die Teile der Luft ausgesetzt sind, was zu Oxidation und Erosion der Kontakte f\u00fchren kann.<\/p>\n\n\n\n

VCCB: Die Lebensdauer ist l\u00e4nger, da das Vakuum im Inneren den Kontaktverschlei\u00df und die Verschmutzung reduziert. Daher ist weniger Wartung erforderlich.<\/p>\n\n\n\n

Verl\u00e4sslichkeit und St\u00e4rke<\/strong><\/h2>\n\n\n\n

ACB: Die Lichtbogenunterbrechung ist bei hohen Str\u00f6men oder hohen Spannungen nicht so gut, da das Luftmedium die Wiederz\u00fcndung des Lichtbogens nicht immer verhindern kann.<\/p>\n\n\n\n

VCB: Sehr zuverl\u00e4ssig und robust bei der Unterbrechung des Lichtbogens, da die Wiederz\u00fcndung des Lichtbogens durch das Vakuum verhindert wird; daher f\u00fcr h\u00e4ufige Eins\u00e4tze geeignet.<\/p>\n\n\n\n

Gr\u00f6\u00dfe und Kosten<\/strong><\/strong><\/h2>\n\n\n\n

ACB: Im Allgemeinen gr\u00f6\u00dfer und wirtschaftlicher in seinen St\u00fcckkosten f\u00fcr Niederspannungsanwendungen.<\/p>\n\n\n\n

VCB: Kompakter und energiesparender, aber aufgrund der angewandten Vakuumkammertechnologie in der Regel teurer, und f\u00fcr Mittelspannungssysteme geeignet.<\/p>\n\n\n\n

Diese Unterschiede machen deutlich, warum ACBs h\u00e4ufig f\u00fcr Niederspannungsanwendungen gew\u00e4hlt werden, w\u00e4hrend VCBs f\u00fcr Mittelspannungsanwendungen bevorzugt werden, bei denen Langlebigkeit und Zuverl\u00e4ssigkeit im Vordergrund stehen.<\/p>","protected":false},"excerpt":{"rendered":"
