标准摘要
[中文适用范围]： IEC 62590-2-1:2025 与IEC 62589以及之前的IEC 62590相比，本文件包含以下重大技术变更：a) 降低对非可控整流器的要求；b) 不同系统连接的接口模型；c) 能源效率问题的处理。IEC 62590的本部分描述了非可控整流器的功能和工作原理，规定了用于直流电力牵引供电系统的非可控整流器的要求、接口和测试方法。非可控整流器通过二极管组件将三相交流电网与直流电力牵引系统连接，实现单向功率流动。变压器与整流二极管组件之间的协调也包含在内。本文件适用于以下电力牵引供电系统的固定安装：• 铁路网络；• 城市交通网络，包括地铁、有轨电车、无轨电车和全自动运输系统、磁悬浮运输系统和电气道路系统。IEC 62590-2-1的第一版，结合IEC 62590系列的其他部分，取代了2010年发布的IEC 62589第一版和2019年发布的IEC 62590第二版。 [外文原描述]： IEC 62590-2-1:2025 This document includes the following significant technical changes with respect to IEC 62589 and the former IEC 62590: a) Reduction of the requirements for uncontrolled rectifiers only; b) Interface model for the different systems connected; c) Energy efficiency addressed. This part of IEC 62590 describes functions and working principles, specifies requirements, interfaces and test methods of uncontrolled rectifiers for DC electric traction power supply systems. Uncontrolled rectifiers connect a 3AC power network with a DC electric traction system with a unidirectional power flow using diode assemblies. The coordination between the transformer and the rectifier diode assembly is included. This document applies to fixed installations of following electric traction power supply systems: • railway networks; • metropolitan transport networks including metros, tramways, trolleybuses and fully automated transport systems, magnetic levitated transport systems, electric road systems. This first edition of IEC 62590-2-1, in conjunction with the other parts of the IEC 62590 series, cancels and replaces the first edition of IEC 62589 published in 2010 and the second edition of IEC 62590 published in 2019.
