Anotation

IEC 63438:2024 applies to the electrical protection system, provided for AC and DC electric traction power supply systems. It: – establishes railway specific protection principles; – describes the railway specific protection system functionality; – specifies minimum functional requirements and informative examples of their application; – establishes limitations of the protection system and the acceptability of residual risks; – specifies principles for design verification. This document is applicable to: – railways; – guided mass transport systems, such as tramways, elevated and underground railways, mountain railways, trolleybus systems, and magnetically levitated systems which use a contact line system. This document can also be applied to electrified road traffic with a contact line, such as truck-trolley systems. This document applies to new electric traction power supply systems and can be applied to changes of existing systems. This document does not apply to: – underground mine traction systems; – cranes, transportable platforms and similar transportation equipment on rails, temporary structures (e.g. exhibition structures) in so far as these are not supplied directly or via transformers from the contact line system and are not endangered by the traction power supply system; – suspended cable cars; – funicular railways; – magnetic levitated systems (without a contact line system); – railways with an inductive power supply without contact system; – railways with a buried contact system that is required to be energized only below the train to ensure safety. This document does not cover: – technical requirements for products, e.g. protection devices; – rules for maintenance of protection systems. IEC 63438:2024 La presente Norme internationale sapplique au systeme de protection electrique qui equipe les reseaux dalimentation de traction electrique a courant alternatif et a courant continu. Elle : – etablit les principes de protection specifiques au domaine ferroviaire ; – decrit la fonctionnalite du systeme de protection specifique au domaine ferroviaire ; – specifie les exigences fonctionnelles minimales et les exemples informatifs de leur application ; – etablit les limites du systeme de protection et lacceptabilite des risques residuels ; – specifie les principes de la verification de la conception. Le present document sapplique aux : – chemins de fer ; – aux reseaux de transport en commun guides tels que les tramways, les chemins de fer aeriens et souterrains, les chemins de fer de montagne, les trolleybus et les systemes a sustentation magnetique qui utilisent un systeme de ligne de contact. Le present document peut egalement etre applique au trafic routier electrifie avec une ligne de contact (les systemes de lorry, par exemple). Le present document sapplique egalement aux nouveaux reseaux dalimentation de traction electrique et peut etre appliquee aux modifications des systemes existants. Le present document ne sapplique pas aux : – systemes de traction miniers souterrains ; – grues, plateformes transportables et materiels de transport similaires sur rails, structures temporaires (dans les foires et expositions, par exemple) dans la mesure ou elles ne sont pas alimentees par les lignes de contact, directement ou par des transfor mateurs, ni affectees par le reseau dalimentation de traction ; – telepheriques ; – funiculaires ; – systemes a sustentation magnetique (sans systeme de ligne de contact) ; – chemins de fer equipes dune alimentation inductive sans systeme de contact ; – chemins de fer equipes dun systeme de contact enterre qui ne doit etre alimente que sous le train afin de garantir la securite. Le present document ne couvre pas : – les exigences techniques pour les produits (les dispositifs de protection, par exemple) ; – les regles de maintenance des systemes de protection.
