DIN EN 45545-5:2016-01 EN 45545-5:2013+A1:2015 (E) 4 Introduction This European Standard has been developed from existing fire safety regulations for railway vehicles from the International Union of Railways (UIC) and different European countries. In using

32、the operation and design categories defined in EN 45545-1, the requirements laid down in the different parts of EN 45545 will take into account the current operating conditions for European public rail transport. DIN EN 45545-5:2016-01 EN 45545-5:2013+A1:2015 (E) 5 1 Scope This Part of EN 45545 spec

33、ifies the fire safety requirements for electrical equipment 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 v

34、ehicles in the event of a fire on board by: lowering the risk 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 4554

41、r railway vehicles are supplemented by the design requirements 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 operat

42、ion (see EN 50125-1). The requirements for cabling and integrity 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 protectio

43、n to be installed between the current collectors and current 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 m

44、ain filter reactor in a traction converter; characteristics 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 ot

45、her overload protection devices (e.g. fuses and circuit 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 shor

46、t as possible; this shall be achieved by ensuring that protective 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

47、 not capable of withstanding the fault current. Precautions may be: preferably fault detection equipment design; operation instruction. DIN EN 45545-5:2016-01 EN 45545-5:2013+A1:2015 (E) 7 5.2 Cabling High power cables shall be contained in a metallic duct or a metallic conduit earth bonded to the b

48、ody if they are running: behind or inside walls; below floors or above ceilings of passenger or staff areas; or if they are passing in or through ventilation ducts, which are connected to passenger or staff areas. Where the line supply protection device cannot be relied upon to operate within 250 ms

49、 after the occurrence of a fault, a device (arc extinguishing device) shall be fitted which can prevent progression of the arc through it along the line supply cable(s). Any cable, where reliance can be placed on the line supply protection device, and any cable that is protected by an arc extinguishing device, shall either be: additionally insulated from the body or underframe to reduce the probability of short circuit arcing initiated by mechanical d
