Power transformer and reactor fittings -- Part 7: Electric pumps for transformer oil

EN 50216-7 covers requirements for electric pumps which generate the circulation of insulating oil in transformers and reactors conforming to the EN 60076 series and their associated cooling systems.
The pumps covered in this standard are rotodynamic pumps driven by a squirrel cage induction motor which is immersed in the insulating oil.
Pump sets conforming to this standard may be of in-line or end suction design.
This standard includes requirements for the electrical and hydraulic performance, mechanical design, routine testing and type testing. Additionally, performance and dimensions of preferred sizes of pump sets are specified (see normative annexes A and B).
The insulating oils considered comply with subclause 2.5 of IEC 60296-1. If other insulating liquids are to be used, the performance and design of the pump shall be agreed between purchaser and manufacturer.

Zubehör für Transformatoren und Drosselspulen -- Teil 7: Elektrische Pumpen für Transformatorenöl

Dieser Teil der EN 50216 legt Anforderungen an elektrische Pumpen fest, die den Umlauf des Isolieröls in Transformatoren und Drosselspulen nach der Reihe 60076 und deren zugeordneten Kühlungseinrichtungen erzeugen.
Die in dieser Norm behandelten Pumpen sind rotationsdynamische Pumpen, die durch einen Kurzschlussläufermotor angetrieben werden, der im Isolieröl eingetaucht ist.
Pumpensätze, die dieser Norm entsprechen, dürfen als Einbaupumpe oder als Anbaupumpe ausgeführt sein.
Diese Norm beinhaltet Anforderungen an das elektrische und hydraulische Betriebsverhalten, die mechanische Ausführung, die Stückprüfung und die Typprüfung. Zusätzlich sind Betriebsverhalten und Abmessungen von bevorzugten Pumpensätzen festgelegt (siehe normative Anhänge A und B).
Die betrachteten Isolieröle entsprechen IEC 60296-1, Abschnitt 2.5. Falls andere Isolierflüssigkeiten zur Anwendung kommen, müssen das Betriebsverhalten und die Ausführung der Pumpe zwischen Käufer und Hersteller vereinbart werden.

Accessoires pour transformateurs de puissance et bobines d'inductance -- Partie 7: Pompes électriques pour transformateur immergé

La EN 50216-7 concerne les règles des groupes électropompes qui engendrent la circulation des huiles isolantes des transformateurs et des inductances conformes à la série de normes EN 60076 et leurs systèmes de refroidissement associés.
Cette norme concerne uniquement les groupes constitués d'une pompe centrifuge et d'un moteur asynchrone triphasé à rotor en court-circuit complètement immergé dans l'huile isolante.
La conception des pompes conformes à cette norme peut présenter une circulation du fluide en ligne ou radiale.
Cette norme définit les caractéristiques électriques et hydrauliques, la conception mécanique, les essais de série et de type. D'autre part, les performances et dimensions recommandées des pompes sont spécifiées (voir annexes A et B).
Les huiles isolantes considérées répondent au paragraphe 2.5 de la CEI 60296 1. Si d'autres liquides isolants sont utilisés, les caractéristiques et la conception de la pompe feront l'objet d'un accord entre l'acheteur et le constructeur.
