EN 3475-605:2010

Aerospace series - Cables, electrical, aircraft use - Test methods - Part 605: Wet short circuit test

This standard specifies a method for appraising the behaviour of cable insulation subjected to an electric arc initiated and maintained by a contaminating fluid.
This standard shall be used together with EN 3475-100.
The primary aim of this test is:
-   to produce, in a controlled fashion, continuous failure effects which are representative of those which may occur in service when a typical cable bundle is damaged and subjected to aqueous fluid contamination such that electrical arcing occurs, between cables; and
-   to examine the aptitude of the insulation to track, to propagate electric arc  to the electrical origin.
Originally defined for 115 Vac network, this test also proposes conditions for 230 Vac network. Unless otherwise specified in product standard, only 115 Vac conditions shall be satisfied.
Six levels of prospective fault current have been specified for concerned cable sizes (see Clause 7). It is generally agreed that larger sizes need not be assessed since the short-circuit phenomenon becomes dominant at low line impedances.
Unless otherwise specified in the technical/product standard sizes 002, 006 and 020 cable shall be assessed.

Luft- und Raumfahrt - Elektrische Leitungen für Luftfahrtverwendung - Teil 605: Verhalten nach Kurzschluss, feucht

Diese Norm legt ein Verfahren zur Beurteilung des Verhaltens der Isolierung einer Leitung gegenüber einem elektrischen Lichtbogen fest, der durch eine Verunreinigungsflüssigkeit erzeugt und aufrechterhalten wird.
Diese Norm ist in Verbindung mit EN 3475 100 anzuwenden.
Der Hauptzweck dieser Prüfung besteht darin,
-   auf geregelte Weise andauernde Fehlereffekte zu erzeugen, die repräsentativ sind für solche, die im Betrieb auftreten können, wenn ein typisches Leitungsbündel beschädigt und einer Verunreinigung durch eine wässrige Flüssigkeit ausgesetzt wird, so dass zwischen den Leitungen Lichtbogen entstehen;
-   zu untersuchen, ob die Isolierung zur Kriechwegbildung neigt, d. h. den Lichtbogen bis zur elektrischen Spannungsquelle auszubreiten.
Diese Prüfung, die ursprünglich für das 115-VAC-Netz festgelegt war, schlägt auch Bedingungen für das 230 VAC-Netz vor. Wenn nicht anders in der Produktnorm festgelegt, sind nur die 115-VAC-Bedinungen einzuhalten.
Sechs prospektive Fehlerstromwerte wurden für die entsprechenden Leitungsgrößen (siehe Abschnitt 7) fest¬gelegt. Es ist im Allgemeinen vereinbart, dass größere Größen nicht bewertet zu werden brauchen, da der Kurz¬schlusseffekt bei niedrigen Leitungsimpedanzen dominierend wird.
Falls in den technischen Normen/Produktnormen nicht anders festgelegt, sind Leitungen der Größen 002, 006 und 020 zu bewerten.

Aeronavtika - Električni kabli za uporabo v zračnih plovilih - Preskusne metode - 605. del: Mokri preskus kratkega stika

Ta evropski standard določa metodo za ocenjevanje obnašanja kabelske izolacije, ki je podvržena električnemu obloku, ki ga ustvarja in vzdržuje kontaminantna tekočina. Ta standard se mora uporabljati skupaj z EN 3475-100. Glavni namen tega testa je: - proizvajati, na nadzorovan način, nepretrgane učinke izpada delovanja, ki so reprezentativni za učinke, do katerih lahko pride med uporabo, kadar je tipičen sveženj kablov poškodovan zaradi kontaminacije z vodno tekočino, tako da pride do električnega obloka, med kabli; in – pregledati sposobnost izolacije za sledenje, za širjenje električnega obloka do električnega vira. Izvirno je definiran za omrežje 115 V izmeničnega toka, a ta preskus predlaga pogoje tudi za omrežje 230 V izmeničnega toka. Razen če je drugače opredeljeno v standardu za izdelke, morajo biti zadovoljeni le pogoji za 115 V izmeničnega toka. Za zadevne velikosti kablov je določenih šest ravni morebitnih okvarnih tokov (glej Klavzulo 7). Splošni dogovor je, da večjih velikosti ni potrebno ocenjevati, ker pojav kratkega stika postane prevladujoč pri nizkih impedancah voda. Razen če je drugače navedeno v tehničnem standardu /standardu za izdelek, je treba ocenjevati kable standardnih velikosti 002, 006 in 020.
