EN 50152-2:2012 includes the following significant technical changes with respect to EN 50152-2:2007: This standard was revised to reflect the latest versions of standards referenced and to remove text already included in the EN
20、 62271 series. The scope was extended to include single-phase and two-phase devices. Definitions were added to provide the necessary precision and to meet the needs of railway applications. Table 1 was reworked according to the changes of EN 50124-1:2001, Table A.2 and Table B.1. Table 2 Coordinatio
21、n table of rated values for devices of the previous version was removed. Ratings previously given under the clause type tests were moved to the new Table 2 Mechanical endurance classes and recommended use.

24、nsformers. BS EN 50152-2:2012EN 50152-2:2012 - 4 - Introduction This standard needs to be read in conjunction with EN 62271-1:2008, EN 62271-102:2002 and/or EN 62271-103:2011, depending on the equipment involved. References in subclauses in EN 62271-102 need to be to EN 62271-1 instead of EN 60694.
25、Where a particular clause of EN 62271-1, EN 62271-102 or EN 62271-103 is not mentioned in this standard, that clause applies as far as reasonable. Where requirements relate exclusively to three-phase systems or to voltages outside those in use in traction systems, they are not applicable. Where this
26、 standard states “addition“ or “replacement“, the relevant text of EN 62271-1, EN 62271-102 and EN 62271-103 needs to be adapted accordingly. When a clause is named applicable to both EN 62271-102 or EN 62271-103, then reference needs to be made only to the standard appropriate for the respective sw
27、itching device. The numbering of clauses in EN 62271 series is not used in this European Standard. The numbering in square brackets refers to the numbering of clauses in EN 62271 series. References specific to numbering of clauses in EN 62271-102 have the prefix 102. and specific to EN 62271-103 hav
28、e the prefix 103. Where terms defined in EN 62271 series conflict with definitions of same terms as given in IEC 60050-811:1991, or the other railway applications documents listed in the normative references, the definitions in EN 62271-1, EN 62271-102 and EN 62271-103 need to be used. NOTE 1 The cl
29、ause numbering in EN 62271-102 and EN 62271-103 is the same as in EN 62271-1. Additional requirements specific to the type of switching device start with subclause numbers from 100. NOTE 2 The suffix N which appears in this standard for rated values is not used in EN 62271 series. BS EN 50152-2:2012
30、- 5 - EN 50152-2:2012 1 Scope This European Standard is applicable to single-pole and two-pole alternating current (a.c.) disconnectors, earthing switches and switches which are: designed for indoor or outdoor fixed installations in tractions systems, and operated with an a.c. line voltage and frequ
31、ency as specified in EN 50163. NOTE 1 EN 50163 specifies the a.c. traction systems 15 kV 16,7 Hz and 25 kV 50 Hz. NOTE 2 As rails of a.c. traction systems are connected to earth and included in the return current path all phase to earth voltages will be within the tolerances as specified in EN 50163
32、. Nevertheless phase to phase voltages are sometimes higher, e.g. in autotransformer systems. NOTE 3 The two poles of a switch can be connected in series to provide secure isolation (i.e. two breaks in series). 2 Normative references The following documents, in whole or in part, are normatively refe
