Rotating electrical machines - Part 18-41: Partial discharge free electrical insulation systems (Type I) used in rotating electrical machines fed from voltage converters - Qualification and quality control tests

Defines criteria for assessing the insulation system of stator/rotor windings which are subjected to pulse width modulation drives. Applies to stator/rotor windings of single or polyphase AC machines with insulation systems for converter operation. Describes qualification and type tests on representative samples or on complete machines which verify fitness for operation with voltage source converters.

Machines électriques tournantes - Partie 18-41: Systèmes d'isolation électrique sans décharge partielle (Type I) utilisés dans des machines électriques tournantes alimentées par des convertisseurs de tension - Essais de qualification et de contrôle qualité

Définit les critères de tests des systèmes d'isolation des bobinages statoriques et rotoriques alimentés par convertisseurs statiques. S'applique aux bobinages statoriques et rotoriques des machines à courant alternatif monophasées ou multiphasées avec un système d'isolation pour le fonctionnement avec un convertisseur. Présente les tests de qualification et d'acceptation réalisés sur des échantillons représentatifs ou sur la machine complète en vue de vérifier son adéquation à l'utilisation sous convertisseur.

Električni rotacijski stroji - 18-41. del: Kvalificiranje in preskusi pri obvladovanju kakovosti električnih izolacijskih sistemov brez delne razelektritve (tip I) v električnih rotacijskih strojih, ki jih napajajo napetostni pretvorniki (IEC 60034-18-41:2014)

Standard EN IEC 60034-18-41 definira kriterije za ocenjevanje izolacijskega sistema navitij statorja/rotorja, ki se uporabljajo v pogonih s pulzno-širinsko modulacijo (PWM) vira napetosti. Uporablja se za navitja statorja/rotorja enofaznih ali večfaznih strojev na izmenični tok z izolacijskimi sistemi za delovanje pretvornika. Standard opisuje kvalifikacijske preskuse in preskuse nadzora kakovosti (preskusi vrste in rutinski preskusi) na reprezentativnih vzorcih ali celotnih strojih, s čimer se preveri primernost stroja za delovanje z napetostnimi pretvorniki. Ta standard se ne uporablja za: - rotacijske stroje, ki jih pretvornik zgolj zažene; - rotacijske električne stroje z efektivno nazivno napetostjo ≤ 300 V; - navitja rotorja rotacijskih električnih strojev, ki delujejo pri največji vrednosti napetosti ≤ 200 V.
