In using the operation and design categories defined in

25、 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.

The measures and requi

27、rements, 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 risk of starting a fire both during operation and as a result of technical defect and/or malfunction of the electrical equipment, en

28、suring that electrical emergency equipment continues to be functional until evacuation is complete (see EN 45545-6). 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

35、rements 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 integrity of connection are specified in EN 50343. The requirement

36、s 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 current consumers of a railway vehicle, consideration shall be given

37、 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; characteristics of the power supply and its protection devices. Where neither

38、 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 breakers) consideration shall be given to the following: the norm

39、al 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 protective devices and transducers for protective devices are inst

40、alled 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. Precautions may be: preferably fault detection equipment design; operatio

41、n instruction. 5.2 Cabling High power cables shall be contained in a metallic duct or a metallic conduit earth bonded to the body if they are running: Copyright European Committee for Standardization Provided by IHS under license with CENNot for ResaleNo reproduction or networking permitted without

Where the line supply protection device cannot be

43、relied upon to operate within 250 ms 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 th

44、at 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 damage; or placed in a metallic tube or a metallic conduit which is earth bonded to the body of the railway ve

45、hicle to reduce the probability of mechanical damage and to ensure the operation of the line supply protection device. These requirements do not apply to flexible connecting cables between body and bogies, but an arc extinguishing device may be fitted at any position in the cabling. If the arc extin

46、guishing device is based on an arc resisting material then this material should typically be a Type B arc barrier material. Precautions shall be taken to ensure that vibration, thermal cycling, expansion/contraction and flexing do not cause damage to cabling and that mechanical stress is not transmi

The material properties are defined as listed product E3C

48、 in Table 2 of EN 45545-2:2013. 5.3.2 Arc barrier Type A A type A arc barrier is a device to contain an electrical arc of short duration, resulting from the normal operation of high power equipment, within a prescribed region. The material properties are defined as listed product E3A in Table 2 of EN 45545-2:2013. The fire resistance is defined as E15 in 5.3 of EN 45545-3:2013. 5.3.3 Arc barrier Type B A type B arc barrier is a device to contain an electrical arc, resulting from a failure of high power equipment, within a prescribed region.
