铁路应用 固定安装 电力牵引架空接触线系统

[中文适用范围]： 本国际标准适用于重型铁路、轻轨、无轨电车和公共及私人运营商的工业铁路的电气牵引架空接触线系统。 它适用于架空接触线系统的新安装和现有架空接触线系统的完全重建。 本文件规定了架空接触线系统设计的要求和测试、结构及其结构计算和验证的要求，以及组件和单个零件设计的要求和测试。 本标准不适用于导体轨道系统，其中导体轨道位于运行轨道旁边。 本文件适用于重型铁路、轻轨、无轨电车线路、电动道路系统1（附录E）以及公共和私人运营商的工业铁路的电气牵引架空接触线系统。本文件适用于架空接触线系统的新安装和现有架空接触线系统的完全更新。 本文件不适用于地面水平导体轨道系统（见图1）。 注：地面水平导体轨道意味着导体轨道位于运行轨道旁边，例如第三轨或地面中的导体轨道。 [外文原描述]： IEC 60913:2024 CMV contains both the official standard and its commented version. The commented version provides you with a quick and easy way to compare all the changes between IEC 60913:2024 edition 3.0 and the previous IEC 60913:2013 edition 2.0. Furthermore, comments from IEC TC 9 experts are provided to explain the reasons of the most relevant changes, or to clarify any part of the content. IEC 60913:2024 specifies the requirements and tests for the design of overhead contact line systems, requirements for structures and their structural calculations and verifications as well as the requirements and tests for the design of assemblies and individual parts. This document is applicable to electric traction overhead contact line systems in heavy railways, light railways, for trolley bus lines, electric road systems (Annex E) and industrial railways of public and private operators. This document is applicable to new installations of overhead contact line systems and for the complete renewal of existing overhead contact line systems. The European standard EN 50119 has served as a basis for the elaboration of this document. This edition includes the following significant technical changes with respect to the previous edition: a) title modified; b) requirements for urban rail systems are included; c) requirements for rigid overhead contact line (ROCL) are included; d) additional definitions for new terms are included (Clause 3); e) clearances and geometry of overhead contact line are improved (Clause 5); f) urban aspects are added, for example wall anchors (Clause 6); g) requirements for monitoring devices, automatic earthing and short-circuiting equipment are included (Clause 7); h) requirements for overhead contact line for electric vehicles with pantograph on electrified roads are added (Annex E) i) improvements on the basis of EN 50119:2020 and the questionnaire 9/2619A/Q
