Rotating electrical machines - Part 33: Synchronous hydrogenerators including motor-generators - Specific requirements

This part of IEC 60034 applies to three-phase salient-pole synchronous generators and synchronous motor-generators for hydraulic turbine and pump-turbine applications, that have rated frequency of 50 Hz or 60 Hz, rated output of 10 MVA and above, pole pair number 3 and above, and rated voltage of 6 kV and above. This document supplements basic requirements for rotating machines given in IEC 60034-1.

Machines électriques tournantes - Partie 33 : Hydro-génératrices synchrones y compris les groupes moteur-générateurs – Exigences spécifiques

IEC 60034-33:2022 s'applique aux génératrices synchrones triphasées à pôles saillants et aux groupes moteur-générateurs synchrones pour les applications de turbines hydrauliques et de pompes-turbines, qui ont une fréquence assignée de 50 Hz ou 60 Hz, une sortie assignée supérieure ou égale à 10 MVA, un nombre de paires de pôles supérieur ou égal à 3, et une tension assignée supérieure ou égale à 6 kV. Le présent document complète les exigences principales pour les machines tournantes données dans l’IEC 60034-1.

Električni rotacijski stroji - 33. del: Sinhronski hidrogeneratorji, vključno z motor-generatorji - Posebne zahteve (IEC 60034-33:2022)

Ta del standarda IEC 60034 se uporablja za trifazne sinhronske generatorje z izpostavljenimi poli in sinhronske motorne generatorje za uporabo s hidravličnimi in črpalnimi turbinami z nazivno frekvenco 50 ali 60 Hz, nazivno močjo 10 MVA in več, številom parov polov 3 in več ter nazivno napetostjo 6 kV in več.
Ta dokument dopolnjuje osnovne zahteve za rotacijske stroje, podane v standardu IEC 60034-1.
