标准摘要
[中文适用范围]： 本部分IEC 61936以方便的形式提供了额定电压高于1.5 kV DC的系统中直流装置设计和安装的要求，以确保安全和预期功能的正常运行。 为了解释本文件，直流装置被认为是以下之一： a) 换流站或直流开关站； b) 一个（或多个）直流发电或存储单元，如太阳能发电场或电池存储单元，位于单一地点，直流装置包括直流设备和电缆，以及所有相关的电力电子、控制设备、开关设备和所有电气辅助系统。位于不同地点的直流发电或存储单元之间的连接不包括在内； c) 为发电、输电、配电和/或储电目的而在海上设施上安装的直流装置；或 d) 直流过渡站（架空线路和地下电缆之间或地下电缆不同段之间）。 本国际标准不适用于以下设计和安装： – 独立装置之间的架空和地下线路； – 电气铁路； – 采矿设备和装置； – 根据IEC 60092系列的船舶装置和根据IEC 61892系列的海上装置，这些装置用于海上石油工业的钻探、加工和储存目的； – 静电设备（如静电除尘器、喷漆装置）； – 试验场地； – 医疗设备，如医用X射线设备； – 阀厅或换流厅。 本文件不适用于对电气装置进行带电工作的要求。 本文件不适用于工厂制造的、型式试验的晶闸管阀、VSC阀和开关设备的设计，这些设备有单独的IEC标准。 [外文原描述]： IEC 61936-2:2023 provides, in a convenient form, requirements for the design and the erection of DC installations in systems with nominal voltages above 1,5 kV DC, so as to provide safety and proper functioning for the use intended. For the purpose of interpreting this document, a DC installation is considered to be one of the following: a) A converter station or DC switching station; b) one (or more) DC generating or storage unit(s), such as solar farms or battery storage units, located on a single site, the DC installation includes DC equipment and cables with all associated power electronics, controlgear, switchgear and all electrical auxiliary systems. Connections between DC generating or storage units located on different sites are excluded; c) DC installation erected on offshore facilities for the purpose of generation, transmission, distribution and/or storage of electricity; or d) DC transition station (between overhead lines and underground cable or between different sections of underground cables). This International Standard does not apply to the design and erection of any of the following: - overhead and underground lines between separate installations; - electric railways; - mining equipment and installations; i- installations on ships according to IEC 60092 series and offshore units according to IEC 61892 series, which are used in the offshore petroleum industry for drilling, processing and storage purposes; - electrostatic equipment (e.g. electrostatic precipitators, spray-painting units); - test sites; - medical equipment, e.g. medical X-ray equipment; - valve hall or converter hall. This document does not apply to the requirements for carrying out live working on electrical installations. This document does not apply to the design of factory-built, type-tested thyristor valves, VSC valves and switchgear for which separate IEC standards exist. This first edition cancels and replaces the IEC TS 61936-2 published in 2015. This edition constitutes a technical revision. See the foreword of this edition for the list of significant technical changes with respect to the previous edition.
