In addition to the design requirements of this Technical Specification, electrical equipment shall be designed to withstand the mechanical, electrical and thermal stresses which are lik

27、ely to be encountered in operation (see EN 50125-1). 1) For this part of the Technical Specification, the unprotected part of a starting circuit is considered as high power. - 7 - CLC/TS 45545-5:2009 The requirements for fire behaviour properties of materials are specified in CEN/TS 45545-2. 6 Desig

28、n requirements 6.1 Overload protection 6.1.1 When selecting the method and setting of overload protection to be installed between the current collectors and consumers of a vehicle, consideration shall be given to the following: values of the short circuit currents; duration of these short circuit cu

29、rrents; any load side components which may modify the fault characteristics, i.e. the main 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

30、 of the supply line (e.g. trolley buses). 6.1.2 When selecting the method and settings of other overload protection devices (fuses, circuit breakers, etc.) consideration shall be given to the following: the normal load; line impedance; source impedance; short circuit characteristics. 6.1.3 The unpro

31、tected parts of circuits shall be as short as possible, this is achieved by ensuring that protective devices and transducers for protective devices are installed as close as possible to the source of supply. 6.1.4 Precautions shall be taken to prevent a protective device from reclosing on to a known

32、 fault, where the electrical equipment is not capable of withstanding the fault current. Precautions could be e.g.: operation instruction; fault detection system design. 6.2 Integrity of connection 6.2.1 Electrical conductors shall be connected reliably by ensuring that: a means is provided (screws,

33、 connectors, etc.) to maintain the necessary contact pressure corresponding to the current rating and the short circuit strength of the apparatus and the circuit; a locking arrangement is provided where the contact pressure would be adversely affected by vibration or thermal cycling; current shall n

34、ot pass through spring washers that are used to maintain the necessary contact pressure; precautions are taken to prevent corrosion of the contact areas. 6.2.2 Any temperature rise that may occur during operation shall not reduce the integrity of cable connections. 6.2.3 Where soldered connections a

35、re used, the cable shall be fixed to exclude mechanical stress at the soldering point. 6.2.4 Where connections are made using wire wrap techniques, they shall comply with EN 60352-1. 6.2.5 Where flat, quick-connect terminations are used, they shall comply with EN 61210 and shall be manufactured from

36、 tinned phosphor bronze. 6.3 Wiring 6.3.1 The size of cables for a circuit shall be selected so that the cable will not be damaged by carrying excessive current before the protective device operates under fault condition. 6.3.2 The wiring shall be installed so that the designed operating temperature

37、 of the cable is not exceeded. CLC/TS 45545-5:2009 - 8 - 6.3.3 Except for supply line cables which have no “on-train electrical protection”, high power cables shall be contained by a metallic duct or a metallic conduit earth bonded to the body if they are running behind or in walls, floors or ceilin

38、gs of passenger or staff areas, or if they are passing in or through ventilation ducts, which are connected to passenger or staff areas. 6.3.4 Where the line supply protection device cannot be relied upon to operate within 250 ms, a device (arc extinguishing device) shall be fitted which can prevent

39、 progression of the arc through it along the line supply cable(s). Cable where reliance can be placed on the line supply protection device and cable protected by an arc extinguishing device shall either be: additionally insulated from the body or underframe to reduce the probability of short circuit

40、 arcing initiated by mechanical damage; or placed in metallic tube or metallic conduit which are earth bonded to the body of the vehicle 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 wiring. If an arc extinguishing device is used, its effectiveness shall be demonstrated by a specific “system test“. If the arc extinguishing device was based on an arc resisting materia
