Railway applications - Rolling stock - Pantographs: Characteristics and tests - Part 1: Pantographs for main line vehicles

This European Standard specifies the general assembly characteristics which are to be applied to pantographs, to enable current collection from the overhead contact line system. It also specifies the tests the pantographs have to perform, excluding insulators. This European Standard is not applicable 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 is not applicable to pantographs used on isolated metros and light rail systems. These pantographs are considered in EN 50206-2.

Ta evropski standard določa splošne karakteristike konstrukcije, ki morajo veljati za odjemnike toka, da omogočijo odjem toka s sistema voznih vodov. Določa tudi preskuse, ki jih morajo opraviti odjemniki toka, razen izolatorjev. Ta evropski standard ne velja za dielektrične preskuse odjemnikov toka, ki se morajo opraviti na odjemnikih toka, nameščenih na strehi vozila. Če se kupec in dobavitelj ne dogovorita o nobenih drugih zahtevah, se lahko uporabi izolacijska koordinacijska zahteva v skladu z EN 50124-1. Ta evropski standard ne velja za odjemnike toka, ki se uporabljajo na izoliranih sistemih mestnih železnic in lahkih železnic. Te odjemnike toka obravnava EN 50206-2.

Introduction
The electrical power supply of a tractive unit is achieved by the collection of current from one or more
contact wires by means of one or more pantograph(s), installed on the traction unit or on the trainset's
vehicle.
The contact strips of the pantograph which slide along the contact wire facilitate the transmission of
power.
The pantograph and the overhead contact line system 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.

6 Tests
6.1 Categories of tests
6.1.1 Overview
There are four categories of tests:
– type tests;
– routine tests;

---------------------- Page: 13 ----------------------

SIST EN 50206-1:2011
EN 50206-1:2010 – 12 –
– investigation tests;
– combined tests.
The above tests are described in 6.1.2 to 6.1.5.
Annex B summarises the tests which shall be performed.
6.1.2 Type tests
This European Standard distinguishes the basic model of a pantograph from the derived model of the
same pantograph. The derived model can incorporate modifications to the basic design which shall be
considered to be covered by the existing relevant type tests. This is provided that any such changes can
be demonstrated to be at least equal to the basic design through calculation or operational experience of
at least two years on a European Railway network, and with technical requirements at least equal to those
for which the basic model was designed.
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.
The acceptance of the apparatus shall not rely on the results of those investigation tests.
6.1.5 Combined tests
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 contact line system defined in the customer
specifications.
These tests apply to both basic and derived pantograph models.
6.2 General tests
6.2.1 Visual inspection (routine test)
The pantograph shall be completely assembled.

defects and surface treatments shall have been carried out (see 4.10).
6.2.2 Weighing (type test)

Test acceptance criteria:
The mass of the pantograph shall comply with the contractual mass as specified in 4.9.
