Annotation of standard text IEC 60076-11-ed.2.0 :
IEC 60076-11:2018 applies to dry-type power transformers (including auto-transformers) having values of highest voltage for equipment up to and including 72,5 kV and at least one winding operating at greater than 1,1 kV. This document does not apply to: - gas-filled dry-type transformers where the gas is not air; - single-phase transformers rated at less than 5 kVA; - polyphase transformers rated at less than 15 kVA; - instrument transformers; - starting transformers; - testing transformers; - traction transformers mounted on rolling stock; - flameproof and mining transformers; - welding transformers; - voltage regulating transformers; - small power transformers in which safety is a special consideration. Where IEC standards do not exist for the transformers mentioned above or for other special transformers, this document may be applicable as a whole or in parts. This second edition cancels and replaces the first edition published in 2004 and constitutes a technical revision. The main changes with regard to the previous edition are as follows: - Extension of the scope up to 72,5kV - Enclosure management in regards of the performance - Management of the dielectric and thermal features with altitude - New climatic classes for a better adaptation of customers’ need - Establishment of the relation between location and environmental classes - For fire behaviour classes, limitation at 1000kVA and process of test more robust - Introduction of Seismic class - Recommendations for amorphous transformers Keywords: dry-type transformers The contents of the corrigendum of March 2019 and the Interpretation sheet 1 of July 2020 have been included in this copy. LIEC 60076-11:2018 applique aux transformateurs de type sec (y compris les autotransformateurs) dont les valeurs de tension la plus elevee pour le materiel sont inferieures ou egales a 72,5 kV avec au moins un enroulement fonctionnant a plus de 1,1 kV. Le present document ne sapplique pas aux: - transformateurs de type sec avec un dielectrique gazeux autre que lair; - transformateurs monophases de moins de 5 kVA; - transformateurs polyphases de moins de 15 kVA; - transformateurs de mesure; - transformateurs de demarrage; - transformateurs dessai; - transformateurs de traction montes sur materiel roulant; - transformateurs antideflagrants et de mines; - transformateurs de soudure; - transformateurs de reglage de tension; - petitstransformateurs de puissance pour lesquels la securite est specialement a prendre en compte. Lorsquil nexiste pas de norme IEC pour les transformateurs mentionnes ci-dessus ou pour dautres transformateurs speciaux, le present document peut etre appliquee en tout ou en partie. Cette deuxieme edition annule et remplace la premiere edition publiee en 2004 dont elle constitue une revision technique. Les principales modifications par rapport a ledition precedente sont les suivantes: - Extension du domaine dapplication jusqua 72,5 kV - Prise en compte des enveloppes en ce qui concerne les performances - Prise en compte des caracteristiques dielectriques et thermiques en fonction de laltitude - Nouvelles classes climatiques pour une meilleure adaptation des besoins des clients - Etablissement de la relation entre lemplacement et les classes denvironnement - Pour les classes de comportement au feu, limitation a 1 000 kVA et processus dessai plus robuste - Introduction dune classe sismique - Recommandations pour les transformateurs amorphes Mots-cles: transformateurs de type sec Le contenu du corrigendum de mars 2019 et la feuille dinterpretation 1 de juillet 2020 (seulement en anglais) a ete pris en consideration dans cet exemplaire.
