(Main)Railway applications - Fixed installations - Electronic power converters for substations
Railway applications - Fixed installations - Electronic power converters for substations
IEC 62590:2019 specifies the requirements for the performance of all fixed installations electronic power converters, using controllable and/or non-controllable electronic valves, intended for traction power supply. The devices can be controlled by means of current, voltage or light. Non-bistable devices are assumed to be operated in the switched mode.
This document applies to fixed installations of the following electric traction systems:
- railways,
- guided mass transport systems such as: tramways, light rail systems, elevated and underground railways, mountain railways, trolleybuses.
This standard is based on EN 50328. This second edition cancels and replaces the first edition published in 2010. This edition includes the following significant technical changes with respect to the previous edition:
a) Incorporation of DC converters.
b) Correction of the clearances and withstand voltages due to erroneous use of PD in former edition.
c) adaption of structure, adaption of vocabulary, removal of unused term and abbreviations.
