BS EN 50562:2018EN 50562:2018 (E) 4 Introduction This European Standard provides a code of practice (CoP) for the process, protective measures and demonstration of safety for the conventional electric traction systems whi

28、ch supports the application of EN 50126. Within this standard “safety” is used with respect to harm to people and environment. Safety in terms of harm to assets is covered in the relevant product and application standards. This standard includes a systems description for the generic reference system

29、 for a conventional electric traction system (refer to Figure 3) and the related subsystems. The interfaces with respect to safety at the system borders and the respective aspects to be coordinated are described. Based on the list of top-level hazards and endangered groups protective measures for ri

30、sk mitigation and hazard control are derived and indications for the verification and validation procedures are given. The list of standards given in Annex B can serve as a reference. During the preparation of this European Standard it became obvious, that the risks associated with conventional elec

31、tric traction systems are broadly accepted. This conclusion is based on long term experience from several European railways. The technical systems used by these European railways in their conventional electric traction systems are equivalent to the generic reference system described in this standard

32、. Confidential field data that were taken into account represent more than 1 200 000 year km operational experience. To exemplify, the equivalent would be a network size of about 80 000 km and the operational experience laid down in traceable field data would cover a period of 15 years of service. N

33、o fatality was reported caused by a product property or a failure of a specified function of the conventional electric traction systems. This standard has been developed specifically to support the realization of EN 50126 within the context of safety for electric traction systems. It provides generi

34、c building blocks which assists the fulfilment of the requirements of life cycle steps given in EN 50126. Product and application standards are traditionally applied in fixed installations to ensure safety and performance in terms of e.g. reliability and cost efficiency. Within this standard the lin

35、k between existing product and application standards, technical specification for interoperability and EN 50126 is given. This standard complies with the principles of the life cycle modelling according to EN 50126 by tailoring the risk assessment process. This means that this standard encompasses t

36、he entire safety process ranging from the system description, hazards identification to the verification and validation of the implemented protective measures according to EN 50126 and it is not just a summation of product and application standards. This standard has been developed so that it can al

37、so be used for assessing risks arising from technical changes within the legal framework of the European Union. This standard also supports the decision making regarding the assessment of changes, e.g. with respect to the significance of changes in technologies. It includes in particular the risk ac

38、ceptance principle regarding the application of codes of practice. It also supports the application of the risk acceptance principles similar reference systems and explicit risk estimation for electric traction systems in the framework of EN 50126. When applying TSIs, e.g. TSI Energy, this standard

39、supports the demonstration of the inherent safety of the conventional electric traction system and supports the safe integration at overall system level. Amongst others this standard can be used as a code of practice for conventional electric traction systems. This does not exclude consideration of

40、other codes of practice even from other fields of application. The interrelation between the legal framework, the standards traditionally applied and the set of standards confined to safety is shown in Figure 1. BS EN 50562:2018EN 50562:2018 (E) 5 Figure 1 Interrelationship between standards and the

41、 legal framework BS EN 50562:2018EN 50562:2018 (E) 6 1 Scope This European Standard defines the process, protective measures and demonstration of safety in accordance with EN 50126 for conventional electric traction systems for railways. This standard can also be applied to guided mass transport sys

42、tems and trolleybus systems. All these systems can be elevated, at-grade and underground. Other systems including those listed below were not assessed and therefore are outside the scope of this European Standard: underground mine traction systems, cranes, transportable platforms and similar transpo

43、rtation 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

44、, railways with inductive power with inductive contactless transmission of the energy from the electric traction power supply system to the electrically powered traction unit, railways with buried contact line system that is required to be energised only below the train to ensure safety, For similar

45、 technology and similar hazardous scenarios, the safety considerations of this standard can be used as a guideline. This European Standard applies to conventional electric traction systems, which are new or are undergoing major changes. 2 Normative references The following documents, in whole or in
