23、ers for traction power supply differ from other converters for industrial use due to special electrical service conditions and due to the large range of load variation and the peculiar characteristics of the load. For these reasons EN 60146-1-1 does not fully cover the requirements of railway applic

24、ations and the decision was taken to have a specific European standard for this use. Converter transformers for fixed installations of railway applications are covered by EN 50329. Harmonization of the rated values and tests of the whole converter group are covered by EN 50327. EN 50328:2003 - 6 - 1

25、 General 1.1 Scope This European Standard 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, voltag

26、e or light. Non-bistable devices are assumed to be operated in the switched mode. This European Standard applies to fixed installations of following electric traction systems: railways, guided mass transport systems such as: tramways, light rail systems, elevated and underground railways, mountain r

27、ailways, trolleybusses. This European Standard does not apply to cranes, transportable platforms and similar transportation equipment on rails, suspended cable cars, funicular railways. This European Standard applies to diode rectifiers, controlled rectifiers, inverters and frequency converters. The

28、 equipment covered in this European Standard is the converter itself. 1.2 Normative references This European Standard incorporates by dated or undated reference provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are lis

EN 50328:2003 - 8 - 1.3.3 Classification of semiconductor valves Semiconductor valves can be turned off either by commutation implying that the current of the valve is trans

38、ferred to another valve or by quenching if the current of the valve falls to zero. Valves used in traction supply power converters can be divided into the following categories: 1) non controllable valve with a conductive forward and a blocking reverse characteristic (diode); 2) valve with a controll

39、able forward and a blocking reverse characteristic (e.g. reverse blocking thyristor); 3) valve with a controllable forward and a conductive reverse characteristic (e.g. reverse conducting thyristor); 4) valve with a controllable forward and / or reverse characteristic which can be turned on and/or o
