Railway applications - Rolling stock - Pantographs: Characteristics and tests - Part 2: Pantographs for metros and light rail vehicles

This European Standard defines the general assembly characteristics which are to be applied to pantographs, to enable current collection from the overhead line equipment. It also defines the tests the pantographs have to perform, excluding insulators. This European Standard does not apply to pantograph dielectric tests, which are to be performed on the pantograph installed on the vehicle roof. If no other requirement is agreed between customer and supplier, insulation coordination according to EN 50124 1 may be used. This European Standard does not apply to pantographs used on main line vehicles: these pantographs are considered in EN 50206 1. This European Standard relates to conventional suspended overhead line equipment and accessories. The systems (or part of them) which are rigidly suspended will require special consideration between the customer and the supplier.

Foreword

This European Standard was prepared by SC 9XB, Electromechanical material on board rolling stock, of

Technical Committee CENELEC TC 9X, Electrical and electronic applications for railways. It was

– simplification and standardisation of the tolerances for static contact force (Annexes A and B);

– adjustment of terms to TSI (static contact force instead of static force);
– deletion of Clause 10;
– update of normative references.

Attention is drawn to the possibility that some of the elements of this document may be the subject of

patent rights. CEN and CENELEC shall not be held responsible for identifying any or all such patent rights.

The following dates were fixed:
– latest date by which the EN has to be implemented
at national level by publication of an identical
national standard or by endorsement
(dop) 2011-05-01
– latest date by which the national standards conflicting
with the EN have to be withdrawn

Introduction

The electrical power supply of a tractive unit is achieved by the collection of current from the contact wire

by means of one or more pantograph(s), installed on the traction unit or on the vehicle.

The contact strip of the pantograph which slides along the contact wire facilitates the transmission of

power.

The pantograph and the overhead line equipment form two oscillating sub-systems which can be

displaced. There exists a unilateral sliding linkage between them, which shall ensure continuous contact.

Their design shall allow for minimum wear of both sub-systems when used.

1 Scope

This European Standard defines the general assembly characteristics which are to be applied to

pantographs, to enable current collection from the overhead line equipment. It also defines the tests the

pantographs have to perform, excluding insulators.

This European Standard does not apply to pantograph dielectric tests, which are to be performed on the

pantograph installed on the vehicle roof. If no other requirement is agreed between customer and supplier,

insulation coordination according to EN 50124-1 may be used.

This European Standard does not apply to pantographs used on main line vehicles: these pantographs

are considered in EN 50206-1.

This European Standard relates to conventional suspended overhead line equipment and accessories.

The systems (or part of them) which are rigidly suspended will require special consideration between the

customer and the supplier.

same pantograph. The derived model can incorporate modifications to the basic design which will be

considered to be covered by the existing type tests, provided that any such changes can be demonstrated

to be at least equal to the basic design through calculation or operational experience.

Type tests shall be performed on a single piece of apparatus of a given design.

Equipment in current manufacture shall be considered to have satisfied the type tests and shall be

exempted from them, if the manufacturer provides signed reports of type tests already made on identical

apparatus constructed previously.

Supplementary type tests shall be required if they are requested in the customer specification and after

agreement with the supplier.

6.1.3 Routine tests

Routine tests shall be carried out to verify that the properties of a product correspond to those measured

during the type test. Routine tests shall be performed by the supplier on each equipment. For certain

apparatus, after agreement between customer and supplier, routine tests may be replaced by sampling

tests (tests performed on a number of apparatus taken at random from a batch).
6.1.4 Investigation tests

Investigation tests are special tests, which are supplementary, and performed on a single item in order to

obtain additional information. They are required only if they are specified in the customer specifications.

Combined tests are special and supplementary tests which can only be carried out in an operating

environment. They shall take into account the type of vehicle to be used, its speed and direction of travel.

They shall be carried out using the track and/or overhead line equipment defined in the customer

specifications.
These tests apply to both basic and derived pantograph models.

These tests shall be carried out if they have been specified in the customer specification and after
