Railway applications - Fixed installations - Particular requirements for alternating current switchgear - Part 2: Disconnectors, earthing switches and switches with nominal voltage above 1 kV

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 frequency 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. 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).

Železniške naprave - Stabilne naprave električne vleke - Posebne zahteve za stikalne naprave za izmenični tok - 2. del: Odklopniki, ozemljilna stikala in stikala za nazivno napetost nad 1 kV

Ta evropski standard se uporablja za odklopnike z enopolnim ali dvopolnim izmeničnim tokom (a.c.), ozemljilna stikala in stikala, za katera velja:
– narejena so za uporabo z notranjimi ali zunanjimi pričvrščenimi napravami v vlečnih sistemih in
– uporabljajo izmenični tok linijskega vodnika, kot je navedeno v standardu EN 50163.
OPOMBA 1 Standard EN 50163 določa vlečne sisteme z izmeničnim tokom 15 kV 16,7 Hz in 25 kV 50 Hz. OPOMBA 2 Ker so tiri vlečnih sistemov z izmeničnim tokom ozemljeni in vključeni v pot povratnega toka, bodo vsi vodniki do ozemljitve v mejah toka, ki so določene v standardu EN 50163. Kljub temu so lahko napetosti med vodniki višje kot na primer v sistemih z avtotransformatorji. OPOMBA 3 Za boljšo izolacijo se lahko dva pola stikala povezujeta v nizih (npr. dva kontakta v nizu).

Foreword

This document (EN 50152-2:2012) has been prepared by CLC/SC 9XC "Electric supply and earthing systems

for public transport equipment and ancillary apparatus (Fixed installations)".
The following dates are fixed:
(dop) 2013-10-15
• latest date by which this document has to be
implemented at national level by publication of
an identical national standard or by
endorsement
(dow) 2015-10-15
• latest date by which the national standards
conflicting with this document have to
be withdrawn
This document supersedes EN 50152-2:2007.

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 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

‘Coordination 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’.

EN 50152 series under the generic title Railway applications  Fixed installations  Particular requirements

for alternating current switchgear is divided as follows:
- Part 1: Circuit-breakers with nominal voltage above 1 kV;

- Part 2: Disconnectors, earthing switches and switches with nominal voltage above 1 kV;

- Part 3-1: Measurement, control and protection devices for specific use in a.c. traction systems 

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.

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 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 switching 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 have 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 clause 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.

1 Scope

This European Standard is applicable to single-pole and two-pole alternating current (a.c.) disconnectors,

sometimes higher, e.g. in autotransformer systems.
