Rotating electrical machines - Part 18-32: Functional evaluation of insulation systems (Type II) - Electrical endurance qualification procedures for form-wound windings

This part of IEC 60034-18 describes qualification procedures for the evaluation of electrical endurance of insulation systems for use in rotating electrical machines using form-wound windings. The test procedures are comparative in nature, such that the performance of a candidate insulation system is compared to that of a reference insulation system with proven service experience. If no reference system is available, the diagram in Annex A is available for use. The qualification procedures of inverter duty insulation system for form-wound windings can be found in IEC 60034-18-42 or IEC 60034-18-41.

Machines électriques tournantes - Partie 18-32: Evaluation fonctionnelle des systèmes d'isolation (Type II) - Procédures de qualification de l'endurance électrique pour enroulements préformés

IEC 60034-18-32:2022 décrit les procédures de qualification pour l'évaluation de l'endurance électrique des systèmes d'isolation utilisés dans les machines électriques tournantes à enroulements préformés sous tension sinusoïdale à la fréquence d'alimentation. Les procédures d'essai pour l'isolation principale sont comparatives, puisque les performances d'un système d'isolation candidat sont comparées à celles d'un système d'isolation de référence dont l'expérience en service a été démontrée. Si aucun système de référence n'est disponible, l'Annexe A décrit un diagramme utilisable. Les procédures de qualification d'un système d'isolation d'onduleur pour enroulements préformés peuvent être consultées dans l'IEC 60034‑18-42 ou l'IEC 60034-18-41. Une nouvelle procédure d'essai informative pour systèmes de contrôle de contrainte est introduite et définie à l'Annexe B. Cette deuxième édition annule et remplace la première édition parue en 2010. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'édition précédente: a. modification du titre; b. simplification des articles; c. diminution du nombre de procédures d'essai; d. inclusion de barres et bobines complètes comme éprouvettes; e. ajout d'un article qui traite des défaillances et des critères de défaillance.

Električni rotacijski stroji - 18-32. del: Funkcionalno vrednotenje izolacijskih sistemov (tip II) - Električno vrednotenje postopkov kvalificiranja za predhodno oblikovana navitja (IEC 60034-18-32:2022)

Ta del standarda IEC 60034-18 opisuje postopke kvalificiranja za vrednotenje električne vzdržljivosti izolacijskih sistemov za uporabo pri električnih rotacijskih strojih, ki uporabljajo predhodno oblikovana navitja. Preskusni postopki so primerjalne narave, in sicer se delovanje primernega izolacijskega sistema primerja z delovanjem referenčnega izolacijskega sistema z dokazanimi izkušnjami pri uporabi. Če referenčni sistem ni na voljo, se lahko uporabi shema iz dodatka A. Postopki kvalificiranja za izolacijski sistem pretvornika za predhodno oblikovana navitja so navedeni v standardu IEC 60034-18-42 ali IEC 60034-18-41.
