Annotation of standard text IEC 60076-22-3-ed.1.0 :
IEC 60076-22-3:2019 applies to liquid to air heat exchangers, using forced air and forced liquid circuits, used 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 this equipment. It also outlines the operation requirements specific to this equipment as well as the preferred dimensions relevant for interchangeability and the type and routine tests to be performed. Keywords: insulating liquid to air heat exchangers in the cooling circuits of power transformers and reactors IEC 60076-22-3:2019 s’applique aux aerorefrigerants, utilisant des circuits a circulation forcee d’air et de liquide, utilises sur les transformateurs de puissance immerges (conformes a l’IEC 60076-1) et les bobines d’inductance (conformes a l’IEC 60076-6) avec ou sans conservateur pour les installations interieures ou exterieures. Elle presente les conditions de service et les exigences mecaniques et electriques communes a cet equipement. Elle presente egalement les exigences de fonctionnement specifiques a cet equipement et les dimensions preferentielles pertinentes pour l’interchangeabilite, ainsi que les essais de type et individuels de serie a realiser. Mots cles: aerorefrigerants dans les circuits de refroidissement des transformateurs de puissance et des bobines d’inductance
