(Main)High-Voltage switchgear and controlgear - Insulating pressurised partitions for gas filled metal enclosures
High-Voltage switchgear and controlgear - Insulating pressurised partitions for gas filled metal enclosures
This document applies to pressurized partitions used in indoor and outdoor installations of high-voltage AC and DC switchgear and controlgear with rated voltages (Ur) above 1 kV AC / 1,5 kV DC and with design pressure higher than 300 kPa, where the gas is used principally for its dielectric and/or arc-quenching properties. The partitions comprise pressurized barriers in electrical equipment not necessarily limited to the following examples: - circuit-breakers; - switch-disconnectors; - disconnectors; - earthing switches; - current transformers; - voltage transformers; - surge arresters; - busbars and connections; - cable connections/terminations; - cable bushings. Partitions which are only pressurized from one side are also covered. 1 kV AC / 1,5 kV DC means it is valid for the apparatus applied and where the partitions are installed; however, the application of voltages below 1 kV AC / 1,5 kV DC as in, for example, current and voltage transformers are not excluded. This document does not apply to high voltage bushings (see EN 60137, EN 61462 and EN 62155).
Hochspannungs-Schaltgeräte und -Schaltanlagen - Isolierende, druckbeaufschlagte Zwischenwände für gasgefüllte metallgekapselte Gehäuse
Appareillage à haute tension - Cloisons isolées sous pression pour enveloppes métalliques sous pression de gaz
Le présent document s'applique aux cloisons sous pression utilisées dans les installations intérieures et extérieures d'appareillages à haute tension en courant alternatif et en courant continu, de tensions assignées (Ur) supérieures à 1 kV en courant alternatif/1,5 kV en courant continu et de pression de calcul supérieure à 300 kPa, où le gaz est principalement utilisé pour ses propriétés diélectriques et/ou d'extinction des arcs. Les cloisons sont équipées de barrières sous pression dans des équipements électriques, notamment: - disjoncteurs; - interrupteurs-sectionneurs; - sectionneurs; - sectionneur de terre; - transformateurs de courant; - transformateurs de tension; - parafoudres; - jeux de barres et raccordements; - raccordements/extrémités de câbles; - traversées de câbles. Les cloisons qui ne sont sous pression que d'un côté sont également couvertes. L'indication 1 kV en courant alternatif/1,5 kV en courant continu signifie que la valeur est valable pour l'appareil utilisé. Toutefois, lorsque les cloisons sont installées, l'application de tensions inférieures à 1 kV en courant alternatif/1,5 kV en courant continu, par exemple dans les transformateurs de courant et de tension, n'est pas exclue. Le présent document ne s'applique pas aux traversées haute tension (voir l'EN 60137, l'EN 61462 et l'EN 62155).
Visokonapetostne stikalne in krmilne naprave - Tlačno izolirane predelne stene za kovinska ohišja, napolnjena s plinom
Ta dokument se uporablja za tlačne predelne stene, ki se uporabljajo v notranjih in zunanjih namestitvah visokonapetostnih stikalnih oziroma krmilnih naprav z izmeničnim in enosmernim tokom ter nazivno napetostjo (Ur), večjo od 1 kV AC/1,5 kV DC, in konstrukcijskim tlakom, večjim od 300 kPa, pri čemer se plin uporablja predvsem zaradi njegovih dielektričnih lastnosti in/ali lastnosti gašenja obloka.
Plini z izolacijskimi lastnostmi so suh zrak, inertni plini (npr. žveplov heksafluorid ali dušik) ali mešanica tovrstnih plinov.
Predelne stene zajemajo tlačne pregrade v električni opremi, ki niso nujno omejene na naslednje primere:
– odklopniki;
– stikala/ločilna stikala;
– ločilniki;
– ozemljitvena stikala;
– tokovni transformatorji;
– napetostni transformatorji;
– prenapetostni odvodniki;
– zbiralke in priključki;
– kabelske povezave/priključki;
– kabelske uvodnice;
– itd.
Zajete so tudi predelne stene, ki so pod tlakom samo z ene strani.
Oznaka 1 kV AC/1,5 kV DC pomeni, da je veljavno za napravo, ki se uporablja, in mesta nameščenih predelnih sten; vendar uporaba napetosti, nižjih od 1 kV AC/1,5 kV DC (kot npr. v tokovnem in napetostnem transformatorju) ni izključena.
Ta dokument se ne uporablja za visokonapetostne kabelske uvodnice (glej standarde EN 60137, EN 61462 in EN 62155).
