La présente partie de l’IEC 60076-22 s’applique aux hydroréfrigérants, utilisant des circuits à circulation forcée d’eau et de liquide, utilisés sur des transformateurs de puissance immergés dans un liquide (conformes à l’IEC 60076-1) et des bobines d’inductance (conformes à l’IEC 60076-6) avec ou sans conservateur pour les installations intérieures ou extérieures. Elle présente les conditions de service et les exigences mécaniques et électriques communes à cet équipement. Elle présente également les exigences de fonctionnement spécifiques à cet équipement et les dimensions préférentielles pertinentes pour l’interchangeabilité, ainsi que les essasi de type et individuels de série à réaliser.

Hladilna oprema za močnostne transformatorje in dušilke – 22-4. del: Toplotni izmenjevalniki izolacijska tekočina-voda (olje-voda)

Ta standard se uporablja za vodne izmenjevalnike toplote s potisnim vodnim in tekočinskim krogom, ki se uporabljajo na v tekočini potopljenih močnostnih transformatorjih v skladu s standardom IEC 60076-1 in reaktorje v skladu s standardom IEC 60076-6 z raztezno posodo in brez nje za notranjo ter zunanjo namestitev. V njem so opisani servisni pogoji ter mehanske in električne zahteve, ki so skupne tej opremi. Določa tudi obratovalne zahteve za posamezno opremo in prednostne dimenzije, ki so pomembne za izmenljivost ter rutinske in tipske preskuse, ki jih je treba opraviti.
