Surge arresters - Part 9: Metal-oxide surge arresters without gaps for HVDC converter stations

EN IEC 60099-9 applies to non-linear metal-oxide resistor type surge arresters without spark gaps designed to limit overvoltages in HVDC converter stations of two terminal, multiterminal and back-to-back type up to and including an operating voltage of 1 100 kV. The standard applies in general to porcelain-housed and polymer-housed type arresters but also to gas-insulated metal enclosed arresters (GIS-arresters) solely used as d.c. bus and d.c. line/cable arresters. Arresters for voltage source converters are not covered. Arresters applied on the a.c. systems at the converter station and subjected to power-frequency voltage of 50 or 60 Hz principally without harmonics are tested as per IEC 60099-4. The arresters on a.c.-filters are tested according to this standard.

Parafoudres - Partie 9: Parafoudres à oxyde métallique sans éclateur pour postes de conversion CCHT

L'IEC 60099-9:2014 s'applique aux parafoudres à résistance variable à oxyde métallique sans éclateur conçus pour limiter les surtensions dans les postes de conversion CCHT de types bi pôles, multi pôles et dos à dos, jusqu'à et y compris une tension de régime de 1 100 kV. La norme s'applique généralement aux parafoudres à enveloppe en porcelaine et à enveloppe synthétique, mais également aux parafoudres sous enveloppe métallique à isolation gazeuse (parafoudres blindés ou parafoudres GIS) utilisés seulement comme parafoudres de bus c.c. et comme parafoudres de câble/ligne c.c. Les parafoudres pour convertisseurs de source de tension ne sont pas couverts. Les parafoudres appliqués sur les réseaux à courant alternatif au poste de conversion et soumis à une tension à fréquence industrielle de 50 Hz ou 60 Hz principalement sans harmonique sont soumis à essai selon l'IEC 60099-4. Les parafoudres sur les filtres c.a. sont soumis à essai selon la présente norme.

Prenapetostni odvodniki - 9. del: Kovinskooksidni prenapetostni odvodniki brez iskrišč za enosmerne visokonapetostne pretvorniške postaje (IEC 60099-9:2014)

Standard EN IEC 60099-9 se uporablja za kovinskooksidne prenapetostne odvodnike z nelinearnimi upori brez iskrišč za omejevanje prenapetosti v enosmernih visokonapetostnih pretvorniških postajah z dvema priključkoma, več priključki in zaporedne vrste do vključno obratovalne napetosti 1100 kV. Standard se na splošno uporablja za odvodnike v porcelanskem in polimernem ohišju, pa tudi za plinsko izolirane odvodnike v kovinskem ohišju (odvodniki GIS), ki se uporabljajo izključno kot enosmerni odvodniki z vodili in enosmerni linijski/kabelski odvodniki. Odvodniki za napetostne pretvornike niso obravnavani. Odvodniki, ki se uporabljajo v izmeničnih sistemih pri pretvorniški postaji in so načeloma brez harmonikov podvrženi napetosti pri napajalni frekvenci 50 ali 60 Hz, se preskusijo v skladu s standardom IEC 60099-4. Odvodniki pri izmeničnih filtrih se preskusijo v skladu s tem standardom.
