标准摘要
[中文适用范围]： This part of IEC 60077 specifies the general service conditions and requirements for all electric equipment installed in power circuits, auxiliary circuits, control and indicating circuits etc., on railway rolling stock. NOTE Some of these rules can, after agreement between the user and the manufacturer, be used for electrical equipment installed on vehicles other than railway rolling stock, such as mine locomotives, trolley buses, etc. The purpose of this document is to harmonize as far as practicable all rules and requirements of a general nature applicable to electric equipment for rolling stock. This is in order to obtain uniformity of requirements and tests throughout the corresponding range of equipment to avoid the need for testing to different standards. All requirements relating to: - the environmental stresses expected during the normal service conditions; - the construction; - the performance and the associated tests which can be considered as general; have therefore been gathered in this document together with specific subjects of wide interest and application, for example temperature rise, dielectric properties, etc. In the event of there being a difference in requirements between this document and a railway rolling stock relevant product standard, then the product standard requirements take precedence. [外文原描述]： IEC 60077-1:2017 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 60077-1:2017 specifies the general service conditions and requirements for all electric equipment installed in power circuits, auxiliary circuits, control and indicating circuits etc., on railway rolling stock. The purpose of this document is to harmonize as far as practicable all rules and requirements of a general nature applicable to electric equipment for rolling stock. This new edition includes the following main technical changes with regard to the previous edition: descriptions regarding insulation coordination, environmental conditions and those of current return and protective bonding are deleted and replaced by references to IEC 62497‑1, IEC 62498-1 and IEC 61991; classification of equipment type is introduced; temperature limits and temperature rise tests are reviewed.
