Bahnanwendungen. Transformatoren und Drosselspulen auf Bahnfahrzeugen Railway applications Traction transformers and inductors on board rolling stock Applications ferroviaires. Transformateurs de traction et bobines d'inductance a bord du materiel roulant
适用范围：This International Standard applies to traction transformers installed on board rolling stock and to the various types of inductors inserted in the power and auxiliary circuits of electric vehicles. NOTE 1 The term "inductor" is used in this standard with the same meaning as the term "reactor" mentioned in IEC 60050(421), IEC 60050(811) and IEC 60289. The inductors mentioned in the first paragraph may be: - filter inductors; - smoothing inductors; - commutation inductors; - protection inductors in static power convertors; - inductive shunts for traction motors; - inductors used for transition between tap changer notches; - braking circuit inductors; - interference suppression inductors. NOTE 2 The requirements of IEC 60076 are applicable to traction transformers where they do not conflict with this standard, or with the specialized IEC publications dealing with traction applications. NOTE 3 For transformers and inductors for static power convertors, reference should also be made to IEC 61287. This standard can also be applied, after agreement between user and manufacturer, to the traction transformers of three-phase a.c. line-side powered vehicles and to the transformers inserted in the single-phase or polyphase auxiliary circuits of vehicles, except for instrument transformers and transformers of a rated output below 1 kVA single-phase or 5 kVA polyphase. This standard does not cover accessories such as tap changers, resistors, heat exchangers, fans, etc., intended for mounting on the transformers or inductors, which shall be tested separately according to relevant rules. When tap changers are an integral part of the transformers, they cannot be separated while the latter are tested. For service conditions, refer to IEC 60077-1, Clause 7.
