High-voltage switchgear and controlgear - Part 207: Seismic qualification for gas-insulated switchgear assemblies, metal enclosed and solid-insulation enclosed switchgear for rated voltages above 1 kV

IEC 62271-207:2023 applies to - gas-insulated switchgear (GIS) assemblies - for alternating current of rated voltages above 52 kV complying with IEC 62271-203, and - for direct current of rated voltages including and above 100 kV, - for indoor and outdoor installations, including their supporting structures, - AC metal-enclosed switchgear and controlgear assemblies for rated voltages above 1 kV and up to and including 52 kV complying with IEC 62271-200, ground or floor mounted, intended to be used under seismic conditions, and - AC solid-insulation enclosed switchgear and controlgear assemblies for rated voltages above 1 kV and up to and including 52 kV complying with IEC 62271-201, ground or floor mounted, intended to be used under seismic conditions. This third edition cancels and replaces the second edition published in 2012. This edition constitutes a technical revision. It also cancels and replaces, through merging, the first edition of IEC TS 62271-210 published in 2013. This edition includes the following significant technical changes with respect to the previous edition: a) modification of the minimum voltage rating from 52 kV to above 1 kV in order to include medium voltage equipment previously being within IEC TS 62271-210 scope; b) further harmonisation of qualification procedures with the revised IEEE Std 693-2018 [1], Annex A and Annex P, including 1) matching this document's required response spectra with IEEE Std 693-2018 performance level spectra and IEC TS 62271-210 spectra, 2) addition of a step-by-step procedure assisting the user of this document to select an appropriate seismic qualification level combining seismic integrity with cost-effective design, 3) addition of analytical earthquake component combination techniques, and 4) reference to publicly available accelerograms specially developed to match the IEEE Std 693-2018 spectra for testing and analysis purposes, since this document and IEC TS 62271-210 spectra are identical in shape with IEEE Std 693 spectra. c) various enhancements of test procedures; d) addition of minimum contents for seismic qualification reports; e) scope extended to cover DC GIS including and above 100 kV.

Appareillage à haute tension - Partie 207: Qualification sismique des ensembles d'appareillages à isolation gazeuse et des appareillages sous enveloppe métallique et sous enveloppe isolante solide pour des tensions assignées supérieures à 1 kV

L'IEC 62271-207:2023 s'applique: - aux ensembles d'appareillages à isolation gazeuse (GIS) - à courant alternatif de tensions assignées supérieures à 52 kV conformes à l'IEC 62271‑203; et - à courant continu de tensions assignées supérieures ou égales à 100 kV; - pour les installations à l'intérieur et à l'extérieur, y compris les charpentes; - aux ensembles d'appareillages sous enveloppe métallique pour courant alternatif de tensions assignées supérieures à 1 kV et inférieures ou égales à 52 kV conformes à l'IEC 62271-200, montés au sol ou sur le plancher, destinés à être utilisés dans des conditions sismiques; et - aux ensembles d'appareillages sous enveloppe isolante solide pour courant alternatif de tensions assignées supérieures à 1 kV et inférieures ou égales à 52 kV conformes à l'IEC 62271-201, montés au sol ou sur le plancher, destinés à être utilisés dans des conditions sismiques. Cette troisième édition annule et remplace la deuxième édition parue en 2012. Cette édition constitue une révision technique. Elle annule et remplace également la première édition de l'IEC TS 62271-210 parue en 2013, avec laquelle elle a été fusionnée. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a) la tension assignée minimale a été modifiée; elle est passée de 52 kV à une valeur supérieure à 1 kV afin d'inclure les équipements à moyenne tension qui relevaient précédemment du domaine d'application de l'IEC TS 62271-210; b) les procédures de qualification ont été harmonisées davantage par rapport aux Annexes A et P révisées de l'IEEE 693-2018 [1], notamment: 1) les spectres de réponse spécifiés du présent document ont été alignés sur les spectres de niveau de performance de l'IEEE 693-2018 et sur les spectres de l'IEC TS 62271‑210; 2) une procédure pas à pas a été ajoutée pour aider l'utilisateur du présent document à choisir un niveau de qualification sismique adéquat qui combine l'intégrité sismique à une conception rentable; 3) des techniques analytiques de combinaison des composantes sismiques ont été ajoutées; et 4) le présent document fait référence aux accélérogrammes accessibles au public qui ont été spécialement élaborés pour correspondre aux spectres de l'IEEE 693-2018 aux fins des essais et des analyses, car les spectres du présent document et de l'IEC TS 62271‑210 ont une forme identique à celles des spectres de l'IEEE 693; c) les procédures d'essai ont fait l'objet de plusieurs améliorations; d) un contenu minimal a été ajouté pour les rapports de qualification sismique; e) le domaine d'application a été étendu pour couvrir les appareillages à isolation gazeuse à courant continu de tensions supérieures ou égales à 100 kV.

Visokonapetostne stikalne in krmilne naprave - 207. del: Seizmična (potresna) kvalifikacija plinsko izoliranih stikalnih sestavov v kovinskih ohišjih in stikalnih sestavov v ohišjih iz trdnih izolacijskih materialov za naznačene napetosti nad 1 kV (IEC 62271-207:2023)

Standard IEC 62271-207:2023 se uporablja za
– plinsko izolirane stikalne sestave (GIS)
– za izmenični tok naznačenih napetosti nad 52 kV v skladu s standardom IEC 62271-203, in
– enosmerni tok naznačenih napetosti 100 kV ali več,
– notranje- in zunanjemontažne naprave, vključno s podpornimi konstrukcijami,
– kovinsko oklopljene talne stikalne sestave za izmenični tok in krmilne sestave za naznačeno napetostjo nad 1 kV do vključno 52 kV, ki so skladni s standardom IEC 62271-200, namenjene za uporabo pod seizmičnimi pogoji, in
– talne stikalne sestave za izmenični tok in krmilne sestave v ohišjih iz trdih izolacijskih materialov za naznačeno napetostjo nad 1 kV do vključno 52 kV, ki so skladni s standardom IEC 62271-201, namenjene za uporabo pod seizmičnimi pogoji.
Tretja izdaja razveljavlja in nadomešča drugo izdajo, objavljeno leta 2012. Ta izdaja je tehnično popravljena izdaja. Prav tako z združitvijo razveljavlja in nadomešča prvo izdajo standarda IEC TS 62271-210, objavljeno leta 2013.
Ta izdaja v primerjavi s prejšnjo vključuje naslednje pomembne tehnične spremembe:
a) spremembo minimalne naznačene napetosti iz 52 kV na nad 1 kV, da se zajame srednjenapetostna oprema, ki je prej spadala v področje uporabe standarda IEC TS 62271-210;
b) nadaljnja uskladitev postopkov kvalificiranja s popravljenim dodatkom A in P standarda IEE Std 693-2018 [1] vključno s/z
1) uskladitvijo spektrov zahtevanega odziva iz tega dokumenta s spektrom ravni delovanja iz standarda IEEE Std 693-2018 in spektrom iz standarda IEC TS 62271-210,
2) dodajanjem postopka po korakih za pomoč uporabniku tega dokumenta pri izbiri ustrezne stopnje seizmične kvalifikacije, ki združuje seizmično celovitost s stroškovno učinkovito zasnovo,
3) dodatnimi tehnikami kombiniranja analitičnih komponent potresa, in
4) referenco na javno dostopne akcelograme, ki so posebej razviti za uskladitev s spektrom iz standarda IEEE Std 693-2018 za preskušanje in analiziranje, saj so spektri iz tega dokumenta in standarda IEC TS 62271-210 po obliki identični spektrom iz standarda IEEE Std 693.
c) različnimi izboljšavami preskusnih postopkov;
d) dodajanjem minimalnih vsebin za poročila o seizmični kvalifikaciji;
e) razširjenim področjem uporabe, da zajema plinsko izolirane stikalne sestave za enosmerni tok, vključno s 100 kV ali več.
