32、 requirements laid down in the different parts of EN 45545 will take into account the current operating conditions for European public rail transport. BS EN 45545-5:2013+A1:2015EN 45545-5:2013+A1:2015 (E) 5 1 Scope This Part of EN 45545 specifies the fire safety requirements for electrical equipment

33、 on railway vehicles, including that of trolley buses, track guided buses and magnetic levitation vehicles. The measures and requirements, specified in this European Standard meet the objective of protecting passengers and staff in railway vehicles in the event of a fire on board by: lowering the ri

34、sk of starting a fire both during operation and as a result of technical defect and/or malfunction of the electrical equipment, ensuring that electrical emergency equipment continues to be functional until evacuation is complete (see EN 45545-6). 2 Normative references The following documents, in wh

41、ements of this European Standard. In addition to the design requirements of this European Standard, electrical equipment shall be designed to withstand the mechanical, electrical and thermal stresses which are likely to be encountered in operation (see EN 50125-1). The requirements for cabling and i

42、ntegrity of connection are specified in EN 50343. The requirements for fire behaviour properties of materials are specified in EN 45545-2. 5 Design requirements 5.1 Overload protection When selecting the method and setting of overload protection to be installed between the current collectors and cur

43、rent consumers of a railway vehicle, consideration shall be given to the following: values of the short circuit currents; duration of these short circuit currents; any load side components which may modify the fault characteristics, e. g. the main filter reactor in a traction converter; characterist

44、ics of the power supply and its protection devices. Where neither pole of the power supply is bonded to earth, the overload protection shall be on both poles of the supply line (e. g. trolley buses). When selecting the method and settings of other overload protection devices (e.g. fuses and circuit

45、breakers) consideration shall be given to the following: the normal load; line impedance; source impedance; short circuit characteristics; breaking capability of the overload protection device. The unprotected parts of circuits shall be as short as possible; this shall be achieved by ensuring that p

46、rotective devices and transducers for protective devices are installed as close as possible to the source of supply. Precautions shall be taken to prevent a protective device from reclosing on to a known fault, where the electrical equipment is not capable of withstanding the fault current. Precauti

47、ons may be: preferably fault detection equipment design; operation instruction.
