Power transformers - Part 22-6: Power transformer and reactor fittings - Electric fans for transformers

IEC 60076-22-6:2021 covers the electric fans used in the cooling circuits of power transformers and reactors. It applies to electric fans mounted on liquid immersed power transformers according to IEC 60076-1 and reactors according to IEC 60076-6 with and without conservator for indoor or outdoor installation. It outlines the service conditions and the mechanical and electrical requirements that are common to all the equipment. The electric fans concerned by this document are of the axially operating type and are for use on liquid to air coolers and for blowing out radiators. This document also outlines the operation requirements specific to each equipment as well as the preferred dimensions relevant for interchangeability and uniform fan assembly and the type and routine tests to be performed.

Transformateurs de puissance - Partie 22-6: Accessoires pour transformateurs de puissance et bobines d'inductance - Ventilateurs électriques pour transformateurs

L’IEC 60076-22-6:2021 couvre les ventilateurs électriques utilisés dans les circuits de refroidissement des transformateurs de puissance et des bobines d’inductance. Elle s’applique aux ventilateurs électriques montés sur des transformateurs de puissance immergés dans un liquide conformes à l'IEC 60076-1 et des bobines d’inductance conformes à l’IEC 60076­6 avec et sans conservateur pour des installations intérieures ou extérieures. Elle définit les conditions de service et les exigences mécaniques et électriques communes à tous ces équipements. Les ventilateurs électriques concernés par le présent document sont de type à fonctionnement axial et sont destinés à être utilisés sur des aéroréfrigérants et pour souffler sur des radiateurs. Le présent document donne également les exigences de fonctionnement spécifiques à chaque équipement ainsi que les dimensions préférentielles pertinentes pour l’interchangeabilité et l'assemblage uniforme du ventilateur, avec également les essais de type et individuels de série à réaliser.
