Anotation

IEC 62590-2-1:2025 This document includes the following significant technical changes with respect to IEC 62589 and the former IEC 62590: a) Reduction of the requirements for uncontrolled rectifiers only; b) Interface model for the different systems connected; c) Energy efficiency addressed. This part of IEC 62590 describes functions and working principles, specifies requirements, interfaces and test methods of uncontrolled rectifiers for DC electric traction power supply systems. Uncontrolled rectifiers connect a 3AC power network with a DC electric traction system with a unidirectional power flow using diode assemblies. The coordination between the transformer and the rectifier diode assembly is included. This document applies to fixed installations of following electric traction power supply systems: • railway networks; • metropolitan transport networks including metros, tramways, trolleybuses and fully automated transport systems, magnetic levitated transport systems, electric road systems. This first edition of IEC 62590-2-1, in conjunction with the other parts of the IEC 62590 series, cancels and replaces the first edition of IEC 62589 published in 2010 and the second edition of IEC 62590 published in 2019. IEC 62590-2-1:2025 Le present document contient les modifications techniques majeures suivantes par rapport a l’IEC 62589 et l’ancienne IEC 62590: a) reduction des exigences pour les redresseurs non commandes uniquement ; b) modele dinterface pour les differents systemes connectes ; c) efficacite energetique abordee. Le present document decrit les fonctions et les principes de fonctionnement, specifie les exigences, les interfaces et les methodes dessai des redresseurs non commandes pour les reseaux dalimentation electrique de traction en courant continu. Les redresseurs non commandes connectent un reseau de distribution 3AC a un systeme de traction electrique en courant continu avec une circulation de puissance unidirectionnelle realisee par des ensembles de diodes. La coordination entre le transformateur et lensemble de diodes de redressement est incluse. Le present document sapplique aux installations fixes des reseaux dalimentation electrique de traction suivants: • reseaux ferroviaires, • reseaux de transport metropolitains, y compris metros, tramways, trolleybus et systemes de transport entierement automatiques, systemes de transport a sustentation magnetique et systemes routiers electriques. Cette premiere edition de l’IEC 62590-2-1, conjointement avec les autres parties de la serie IEC 62590, annule et remplace la premiere edition de l’IEC 62589 publiee en 2010 et la deuxieme edition de l’IEC 62590 publiee en 2019.
