Annotation of standard text IEC 62271-1-ed.2.1 :
IEC 62271-1:2017+A1:2021 applies to AC switchgear and controlgear designed for indoor and/or outdoor installation and for operation at service frequencies up to and including 60 Hz and having rated voltages above 1 000 V.This document applies to all high-voltage switchgear and controlgear except as otherwise specified in the relevant IEC standards for the particular type of switchgear and controlgear.This second edition cancels and replaces the first edition published in 2007 and Amendment 1:2011. This edition constitutes a technical revision.This edition includes the following significant technical changes with respect to the previous edition:New numbering in accordance with ISO/IEC directives, Part 2 (2016) and IEEE Std. C37.100.1.4.1.2 a) The normal service condition for indoor switchgear is limited to one range of 40 °C to -5 °C.4.1.3 a) The normal service condition for outdoor switchgear is limited to one range of 40 °C to -25 °C.4.2.2: The specifications from IEC 60071-2:1996 are adopted for altitude correction factors above 1 000 m.5.2.2: Range I, the rated voltage of 40,5 kV is added Series I Table 1; Table 2 and Table 4 are updated on recommendation of the US National Committee.6.8: New subclause added for manual operated actuators consistent with “Man Machine Interface” recommendations of IEC 60447 .7.2.6.1:Insert the wording regarding preliminary impulses across open vacuum interrupters according to the result of IEC 17/1026/RQ.7.3: Changed the requirement for radio interference voltage to a rated voltage level of 245 kV and above, instead of 123 kV and above. This change is based on reported positive test and service experience of utility representatives in the maintenance team of this standard.7.5.6, Table 14:a. Introduced the distinction of parts in “OG” (oxidizing gas) or in “NOG” (not oxidizing gas) replacing the former “air” and “SF6”;b. Increased the allowable temperature rise for some parts in groups 1 and 2 of Table 14 according to IEC TR 60943;c. Expanded the definition of allowable temperature rise for categories of accessible surfaces with reference to IEC Guide 117. See also Point 15 in 7.5.6.2.7.5.6.2: Point 5 is modified to clarify the introduction of “OG” and “NOG” gas.7.10: Some tests were removed because the relevant test standards of IEC 60068 series were modified or withdrawn.7.11.3: The acceptance criteria for X-radiation testing are modified to recognize higher rated vacuum interrupters.Former informative Annex H: Corrosion is deleted, the content is part ofIEC TR 62271-306.New Annex J (informative): Added informative guidelines for the extension of validity of type testsNew Annex K (informative): Added informative guidelines about exposure to pollutionThe contents of the Interpretation Sheet 1 of May 2021 have been included in this copy. L’IEC 62271:2017+A1:2021 sapplique a lappareillage a courant alternatif prevu pour etre installe a linterieur et/ou a lexterieur et pour fonctionner a des frequences de service inferieures ou egales a 60 Hz, et ayant des tensions assignees superieures a 1 000 V.Ce document sapplique a tout lappareillage a haute tension, sauf specification contraire dans les normes particulieres de l’IEC pour le type dappareillage considere.Cette deuxieme edition annule et remplace la premiere edition parue en 2007 et lAmendement 1:2011. Cette edition constitue une revision technique.Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente:Nouvelle numerotation conformement aux Directives ISO/IEC, Partie 2 (2016) et a l’IEEE Std. C37.100.1.4.1.2 a): Limitation des conditions normales de service de l’appareillage pour l’interieur a une plage de 40 °C a –5 °C.4.1.3 a): Limitation des conditions normales de service de l’appareillage pour l’exterieur a une plage de 40 °C a –25 °C.4.2.2: Adoption des specifications de l’IEC 60071-2:1996 pour les facteurs de correction de l’altitude superieure a 1 000 m.5.2.2: Plage I, ajout de la tension assignee de 40,5 kV au Tableau 1 Serie I; mise a jour du Tableau 2 et du Tableau 4 sur recommandation du comite national US.6.8: Ajout d’un nouveau paragraphe pour les organes de commande a man?uvre manuelle conformes aux recommandations relatives a l’Interface Homme-Machine de l’IEC 60447.7.2.6.1: Insertion du libelle concernant les impulsions preliminaires dans les ampoules a vide ouvertes selon le resultat de l’IEC 17/1026/RQ.7.3: Modification de l’exigence relative a la tension de perturbation radioelectrique a une tension assignee superieure ou egale a 245 kV, au lieu d’une tension assignee superieure ou egale a 123 kV. Cette modification est basee sur des essais et retours d’experience positifs rapportes par les representants des utilites membres de l’equipe de maintenance de la presente norme.7.5.6, Tableau 14:a. Introduction de la distinction des parties dans les ""OG"" (gaz oxydants) et dans les ""NOG"" (gaz non oxydants) qui remplacent ici les termes ""air"" et ""SF6"" de l’edition precedente.b. Augmentation de l’echauffement admissible pour certaines parties des groupes 1 et 2 du Tableau 14 selon l’IEC TR 60943;c. Extension de la definition de l’echauffement admissible pour des categories de surfaces accessibles en reference au Guide IEC 117. Voir egalement le point 15 de 7.5.6.2.7.5.6.2: Modification du Point 5 pour clarifier l’introduction des gaz ‘’OG’’ et ‘’NOG’’.7.10: Suppression de certains essais du fait de la modification ou suppression des normes d’essais correspondantes de la serie IEC 60068.7.11.3: Modification des criteres d’acceptation des essais de rayonnements X pour prendre en compte les ampoules a vide de tension assignee superieure.Ancienne Annexe H informative: Le contenu concernant la corrosion est supprime car il fait partie de l’IEC TR 62271-306.Nouvelle Annexe J (informative): Ajout de lignes directrices informatives relatives a l’extension de la validite des essais de type.Nouvelle Annexe K (informative): Ajout de lignes
