High-voltage switchgear and controlgear - Gas-filled welded composite enclosures of cast and wrought aluminium alloys
This document applies to welded composite enclosures of cast and wrought aluminium alloy pressurized with dry air, inert gases (e.g. sulphur hexafluoride or nitrogen or a mixture of such gases), used in indoor and outdoor installations of high-voltage switchgear and controlgear with rated voltages above 1 kV, where the gas is used principally for its dielectric and/or arc-quenching properties with rated voltages: - above 1 kV and up to and including 52 kV concerning gas-filled compartments with design pressure higher than 300 kPa relative pressure (gauge); - above 52 kV concerning all gas-filled compartments. The enclosures comprise parts of electrical equipment not necessarily limited to the following examples: - circuit-breakers; - switch-disconnectors; - disconnectors; - earthing switches; - current transformers; - voltage transformers; - surge arrestors; - busbars and connections; - etc. The scope also covers enclosures of pressurized components such as the centre chamber of live tank switchgear, gas-insulated current transformers, etc.

Appareillage électrique haute tension - Enveloppes soudées en alliage d'aluminium comportant des parties moulées et des parties en métal corroyé sous pression de gaz
Le présent document s'applique aux enveloppes soudées en alliage d´aluminium comportant des parties moulées et des parties en métal corroyé sous pression d'air sec et de gaz inertes (par exemple, l'hexafluorure de soufre ou l'azote ou un mélange de tels gaz), utilisées dans les installations intérieures et extérieures d'appareillage à haute tension sous des tensions assignées supérieures à 1 kV. Le gaz est utilisé principalement pour ses propriétés diélectriques et/ou d'extinction de l'arc avec des tensions assignées: - supérieures à 1 kV et inférieures ou égales à 52 kV, en ce qui concerne les compartiments à remplissage de gaz dont la pression de calcul est supérieure à une pression relative (manométrique) de 300 kPa; - supérieures à 52 kV, en ce qui concerne tous les compartiments à remplissage de gaz. Exemples de parties d'équipements électriques contenues dans les enveloppes: - disjoncteurs; - interrupteurs-sectionneurs; - sectionneurs; - sectionneurs de terre; - transformateurs de courant; - transformateurs de tension; - parafoudres; - jeux de barres et barres de raccordement; - etc. Le domaine d'application couvre également les enveloppes de composants sous pression tels que le carter d'appareillage à mécanisme sous tension, les transformateurs de courant à isolation gazeuse, etc.
Visokonapetostne stikalne in krmilne naprave - S plinom polnjena varjena kompozitna ohišja iz litih in gnetljivih aluminijevih zlitin
Ta evropski standard se uporablja za varjena kompozitna ohišja iz lite in gnetljive aluminijeve zlitine s suhim zrakom ter inertnimi plini pod tlakom (npr. žveplov heksafluorid ali dušik ali mešanica takih plinov), ki se uporabljajo v notranjih in zunanjih namestitvah visokonapetostnih stikalnih ter krmilnih naprav z nazivnimi napetostmi nad 1 kV, pri čemer se plin uporablja predvsem zaradi njegovih dielektričnih lastnosti in/ali lastnosti gašenja obloka z nazivnimi napetostmi.
– nad 1 kV in do vključno 52 kV ter s plinskimi razdelki s predvidenim tlakom, višjim od 300 kPa relativnega tlaka (merilnik);
– in z nazivno napetostjo nad 52 kV.
Ohišja zajemajo dele električne opreme, ki niso nujno omejeni na naslednje primere delov:
– odklopniki,
– stikala/ločilna stikala,
– ločilniki,
– ozemljitvena stikala,
– tokovni transformatorji,
– napetostni transformatorji,
– prenapetostni odvodniki,
– zbiralke in priključki,
– drugi deli.
Področje uporabe zajema tudi ohišja s komponentami pod tlakom, kot so sredinska komora stikalne komore pod napetostjo, plinsko izolirani tokovni transformatorji itd.
