EN 50464-4:2007

Three-phase oil-immersed distribution transformers 50 Hz, from 50 kVA to 2 500 kVA with highest voltage for equipment not exceeding 36 kV - Part 4: Requirements and tests concerning pressurised corrugated tanks

This Part 4 of EN 50464 series is applicable to test procedures to verify the mechanical withstand capability of the corrugated tanks of completely oil filled and hermetically sealed distribution transformers. NOTE Variations of oil temperature due to variations of ambient temperature and loading, result in deformation of tank walls.

Ölgefüllte Drehstrom-Verteilungstransformatoren 50 Hz, 50 kVA bis 2 500 kVA mit einer höchsten Spannung für Betriebsmittel bis 36 kV - Teil 4: Anforderungen und Prüfungen für druckbeanspruchte Wellwandkessel

Dieser Teil 4 aus der EN 50464-Reihe ist anwendbar für Prüfverfahren zum Nachweis des mechanischen Stehvermögens von Wellwandkesseln von vollständig ölgefüllten und hermetisch geschlossenen Verteilungstransformatoren. ANMERKUNG Änderungen der Öltemperatur durch Änderungen der Umgebungstemperatur und der Belastung, führen zu einer Verformung der Kesselwände.

Transformateurs triphasés de distribution immergés dans l'huile, 50 Hz, de 50 kVA à 2 500 kVA, de tension la plus élevée pour le matériel ne dépassant pas 36 kV - Partie 4: Prescriptions et essais relatifs aux cuves sous pression

La présente Partie 4 de la série EN 50464 est applicable aux procédures d'essai destinées à vérifier la résistance mécanique des cuves ondulées de transformateurs de distribution complètement remplis d'huile et hermétiquement scellés. NOTE Les variations de la température d'huile dues aux variations de la température ambiante et de la charge conduisent à des déformations des parois de la cuve.
