Adjustable speed electrical power drive systems - Part 5-1: Safety requirements - Electrical, thermal and energy

IEC 61800-5-1:2007 It specifies requirements for adjustable speed power drive systems, or their elements, with respect to electrical, thermal and energy safety considerations. It does not cover the driven equipment except for interface requirements. It applies to adjustable speed electric drive systems which include the power conversion, drive control, and motor or motors. Excluded are traction and electric vehicle drives. It applies to d.c. drive systems connected to line voltages up to 1 kV a.c., 50 Hz or 60 Hz and a.c. drive systems with converter input voltages up to 35 kV, 50 Hz or 60 Hz and output voltages up to 35 kV. The major areas of change in this edition are the following:
- addition of alphabetical Table 1 in Clause 3;
- addition of Table 2 in 4.1 for relevance to PDS/CDM/BDM;
- addition of Table 4 summary of decisive voltage class requirements;
- expansion of subclause on protective bonding (4.3.5.3);
- clarification of distinction between touch current and protective conductor current;
- revision of section on insulation (now 4.3.6) to include solid insulation;
- addition of overvoltage categories I and II to HV insulation voltage;
- revision of section on Solid insulation (now 4.3.6.8);
- addition of high-frequency insulation requirements (4.3.6.9, Annex E);
- addition of requirements for liquid-cooled PDS (4.4.5);
- addition of climatic and vibration tests (5.2.6);
- clarification of voltage test procedure to avoid over-stress of basic insulation (5.2.3.2.3);
- revision of short-circuit test requirement for large, high-voltage and one-off PDS (now 5.2.3.6);
- addition of informative Annex B for overvoltage category reduction.

Entraînements électriques de puissance à vitesse variable - Partie 5-1: Exigences de sécurité - Electrique, thermique et énergétique

L'IEC 61800-5-1:2007 spécifie les exigences pour les entraînements électriques de puissance à vitesse variable, ou leurs éléments, en ce qui concerne les considérations de sécurité électrique, thermique et énergétique. Elle ne couvre pas l'équipement entraîné, à l'exception des exigences pour les interfaces. Elle s'applique aux systèmes d'entraînement électrique à vitesse variable qui comprennent le convertisseur de puissance, le système de commande et un ou plusieurs moteurs. En sont exclus les entraînements pour les véhicules électriques et la traction. Elle s'applique aux systèmes d'entraînement c.c. connectés à des réseaux de tension inférieure ou égale à 1 kV c.a., 50 Hz ou 60 Hz et aux systèmes d'entraînement c.a. avec des tensions d'entrée de convertisseur inférieures ou égales à 35 kV, 50 Hz ou 60 Hz et de sortie de convertisseur inférieures ou égales à 35 kV. Les principaux domaines de modification dans cette deuxième édition sont les suivants:
- ajout du Tableau 1 alphabétique à l'Article 3,
- ajout du Tableau 2 en 4.1 pour la pertinence par rapport aux EEP/MEC/MEP,
- ajout du Tableau 4, résumé des exigences des classes de tension déterminante,
- extension du paragraphe sur les liaisons de protection (4.3.5.3),
- éclaircissement de la différence entre courant de contact et courant dans le conducteur de protection,
- révision du paragraphe sur l'isolement (désormais 4.3.6) pour inclure l'isolation solide,
- ajout de la catégorie de surtension I et II à la tension d'isolement des circuits haute tension,
- révision du paragraphe sur l'isolation solide (désormais 4.3.6.8),
- ajout d'exigences pour l'isolement haute fréquence (4.3.6.9, Annexe E),
- ajout d'exigences pour l'EEP à refroidissement par liquide (4.4.5),
- ajout d'essais climatiques et de vibration (5.2.6),
- éclaircissement de la procédure d'essai de tension pour éviter les sur-contraintes de l'isolement principal (5.2.3.2.3),
- révision de l'exigence d'essai de court-circuit pour un EEP important, à haute tension et unique (désormais 5.2.3.6),
- ajout de l'Annexe B informative pour la réduction de la catégorie de surtension.
