Railway applications - Rolling Stock - Three-phase shore (external) supply system for rail vehicles and its connectors

The shore supply system is used while the rolling stock is standing still within depots and sidings location for providing power to the AC auxiliary loads (which can include battery charging) when the primary power supply (contact line) is not available or used. This document: - specifies requirements to the shore supply and to the rolling stock for safe operation on shore supply operation; - specifies the requirements to ensure compatibility of class C0 and C1 train types as given in CLC/TS 50534:2010 systems and three-phase shore power supply systems; - provides a complete system design for 63/125 A shore supplies including the interfaces (power and control loop) between shore supply and rolling stock; - specifies the requirements with regards to interoperability with AC and DC fed traction systems in order to prevent undesired stray currents and adverse interaction with signalling systems when operating on shore supply; - defines the electrical characteristics of the 63/125 A shore power supply; - defines the 63/125 A connectors and its intermateability to provide interoperability for rolling stock that is to run across borders; - defines the 600 A connector and its intermateability; - can be used for other type of rail vehicles and purposes, if agreed by the manufacturer and customer - does not apply to shore supplies to move the rolling stock; - does not describe the 600 A shore supply system. NOTE 1 The 600 A connector is the existing UK standard three-phase shore supply connector which has a long service history. NOTE 2 The connectors are dimensioned using standard rolling stock cables as set out in EN 50264-3-1:2008. NOTE 3 Examples of other usage and rail vehicles are: e.g. light rail vehicles, class A train types, traction battery charging etcetera.

Applications ferroviaires - Matériel roulant - Système d'alimentation à quai (externe) triphasée des véhicules ferroviaires par connecteurs

Le système d'alimentation à quai est utilisé lorsque le matériel roulant est à l'arrêt dans les dépôts et sur les voies de service, pour fournir de l'énergie aux charges auxiliaires en CA (lesquelles peuvent inclure des dispositifs de charge de batterie) lorsque l'alimentation électrique principale (ligne de contact) n'est pas disponible ou est déjà utilisée. Le présent document : - spécifie les exigences relatives à l'alimentation à quai et au matériel roulant afin de garantir la sécurité de marche lorsque l'alimentation se fait côté quai ; - spécifie les exigences visant à garantir la compatibilité des types de trains de classes C0 et C1 conformément à la CLC/TS 50534:2010 ainsi que des systèmes d'alimentation électrique à quai triphasée ; - suggère une conception complète du système d'alimentation à quai 63/125 A, comprenant les interfaces (alimentation et boucle de commande) entre l'alimentation à quai et le matériel roulant ; - spécifie les exigences d'interopérabilité avec les systèmes de traction alimentés en courant alternatif et en courant continu afin de prévenir les courants vagabonds indésirables et les interactions néfastes avec les systèmes de signalisation lorsque l'alimentation se fait côté quai ; - définit les caractéristiques électriques de l'alimentation électrique à quai 63/125 A ; - définit les connecteurs 63/125 A et leurs modalités d’accouplement afin de garantir l'interopérabilité d'un matériel roulant destiné à traverser les frontières ; - définit le connecteur 600 A et ses modalités d’accouplement ; - peut être utilisé pour d'autres types de véhicules ferroviaires et à d'autres fins, si ce point fait l'objet d'un accord entre le fabricant et le client ; - ne s'applique pas aux systèmes d'alimentation à quai destinés au déplacement du matériel roulant ; - ne décrit pas le système d'alimentation à quai 600 A. NOTE 1 Le connecteur 600 A est le connecteur d'alimentation à quai triphasée couramment utilisé au Royaume-Uni, où il est en usage depuis longtemps. NOTE 2 Les connecteurs sont dimensionnés à partir des câbles pour matériel roulant normalisés dans l'EN 50264 3 1:2008. NOTE 3 Les véhicules légers sur rail, les types de trains de classe A, la charge des batteries de traction sont des exemples d'autres véhicules ferroviaires et d'autres usages.
