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]： 本文件规定了架空接触网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。 本文件适用于重型铁路、轻型铁路、无轨电车线路、电动道路系统（附件E）以及公共和私营运营商的工业铁路的电力牵引架空接触网系统。本文件适用于架空接触网系统的新安装和现有架空接触网系统的全面更新。 本文件不适用于地面导体轨道系统（见图1）。 注：地面导体轨道是指位于运行轨道旁边的导体轨道，例如第三轨或地面上的导体轨道。 图1 – 接触网系统的范围 [外文原描述]： 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
