IEC 62271-103:2011

High-voltage switchgear and controlgear - Part 103: Switches for rated voltages above 1 kV up to and including 52 kV

IEC 62271-103:2011 is applicable to three-phase, alternating current switches and switch-disconnectors for their switching function, having making and breaking current ratings, for indoor and outdoor installations, for rated voltages above 1 kV up to and including 52 kV and for rated frequencies from 162/3 Hz up to and including 60 Hz. This standard is also applicable to single-pole switches used on three phase systems. This standard cancels and replaces the third edition of IEC 60265-1, published in 1998. It constitutes a technical revision. This edition includes the following significant technical changes with respect to IEC 60265-1:1998:
- the rated voltage of 52 kV is now included;
- the document is aligned with IEC 62271-1 and IEC 62271-100;
- addition of a test procedure for short-circuit making tests;
- introduction of notion of NSDD (non-sustained disruptive discharge) as defined in IEC 62271-1 and restrikes;
- new classes C1 and C2 for capacitive switching;
- new Annex A defining tolerances.
This publication is to be read in conjunction with IEC 62271-1:2007. The contents of the corrigendum of October 2013 have been included in this copy.

Appareillage à haute tension - Partie 103: Interrupteurs pour tensions assignées supérieures à 1 kV et inférieures ou égales à 52 kV

La CEI 62271-103:2011 est applicable aux interrupteurs et interrupteurs-sectionneurs à courant alternatif triphasé ayant des pouvoirs de coupure et de fermeture assignés, prévus pour l'installation à l'intérieur et à l'extérieur, de tension assignée supérieure à 1 kV et inférieure ou égales à 52 kV et de fréquences assignées allant de 16 2/3 Hz jusqu'à et y compris 60 Hz. La présente norme est également applicable aux interrupteurs unipolaires prévus pour des réseaux triphasés. La présente norme annule et remplace la troisième édition de la CEI 60265-1 parue en 1998. Elle constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à la CEI 60265-1:1998:
- la tension assignée de 52 kV est désormais comprise;
- le document est aligné avec la CEI 62271-1 et la CEI 62271-100;
- ajout d'une procédure d'essai pour les essais d'établissement de courant de court-circuit;
- introduction du concept de NSDD (décharge disruptive non soutenue) comme défini dans la CEI 62271-1 et des réamorçages;
- nouvelles classes C1 et C2 pour man uvre de charges capacitives;
- nouvelle Annexe A définissant les tolérances.
Cette publication doit être lue conjointement avec l'IEC 62271-1:2007. Le contenu du corrigendum d'octobre 2013 a été pris en considération dans cet exemplaire.
