(Main)High-voltage switchgear and controlgear - Part 109: Alternating-current series capacitor by-pass switches
High-voltage switchgear and controlgear - Part 109: Alternating-current series capacitor by-pass switches
IEC 62271-109:2019 is applicable to AC series capacitor by-pass switches designed for outdoor installation and for operation at frequencies of 50 Hz and 60 Hz on systems having voltages above 52 kV. It is only applicable to by-pass switches for use in three-phase systems. This document is also applicable to the operating devices of by-pass switches and to their auxiliary equipment. This third edition cancels and replaces the second edition published in 2008 and Amendment 1:2013. This edition constitutes a technical revision. This edition contains the following significant technical changes with respect to the previous edition:
a) the document has been restructured according to edition 2.0 of IEC 62271-1;
b) the rated voltage assignation across the by-pass switch has been aligned to the rule defined in IEC 60143-1;
c) clarification has been given regarding rated continuous current of compensated and uncompensated line;
d) some clarifications have been given following a loss of "suitable precautions";
e) as per Amendment 2 of IEC 62271-100, the section "Rated time quantities" has been moved to Clause 6 under "Time quantities";
f) as per Amendment 2 of IEC 62271-100, the section "Test for static mechanical loads" have been moved to Clause 6 under "Static mechanical loads";
g) additional rules have been introduced for vacuum interrupters during impulse tests;
h) additional clarifications have been given regarding the number of reduced impulses during impulse tests;
i) a wider tolerance on the current damping during by-pass making current test-duty has been introduced.
Appareillage à haute tension - Partie 109 : Interrupteurs de contournement pour condensateurs série à courant alternatif
L’IEC 62271-109:2019 est applicable aux interrupteurs de contournement pour condensateurs série à courant alternatif conçus pour l'installation à l'extérieur et pour fonctionner à des fréquences de 50 Hz et 60 Hz, sur des réseaux de tensions supérieures à 52 kV. Elle s’applique uniquement aux interrupteurs de contournement destinés à être utilisés dans les systèmes triphasés. Le présent document est également applicable aux dispositifs de commande des interrupteurs de contournement et à leurs équipements auxiliaires. Cette troisième édition annule et remplace la deuxième édition parue en 2008 et son Amendement 1:2013. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente:
a) le document a été remanié selon l’édition 2.0 de l’IEC 62271-1;
b) l'assignation de tensions assignées aux bornes de l’interrupteur de contournement a été alignée sur la règle définie dans l’IEC 60143-1;
c) des précisions ont été apportées au sujet du courant permanent assigné de la ligne compensée et de la ligne non compensée;
d) des clarifications ont été apportées suivant une perte des "précautions appropriées";
e) conformément à l’Amendement 2 de l’IEC 62271-100, la section "Durées assignées" a été déplacée à l’Article 6 sous "Durées";
f) conformément à l’Amendement 2 de l’IEC 62271-100, la section "Essai des charges mécaniques statiques" a été déplacée à l’Article 6 sous "Charges mécaniques statiques";
g) des règles supplémentaires ont été introduites pour les ampoules à vide pendant les essais de chocs;
h) des clarifications supplémentaires ont été apportées au sujet du nombre de chocs réduits pendant les essais de chocs;
i) une tolérance plus grande pour l'amortissement du courant pendant la séquence d’essai d’établissement du courant de contournement a été introduite.
