交流电压超过1kV的电力装置.第1部分:通用规则

[中文适用范围]： IEC 61936-1提供了额定电压超过1 kV交流电且额定频率不超过60 Hz的电力系统的设计和建设要求，旨在为预定用途提供安全和正常功能。对于本文件的解释目的，电气power installation被视为以下之一：a) 变电站（包括铁路供电变电站）；b) 位于封闭电气操作区之外的电线杆、杆塔和塔上的电气power installation、开关设备和/或变压器；c) 位于单个场地的一个或多个电站，电气power installation包括发电机、变压器、所有相关的开关设备和所有电气辅助系统。位于不同场地的发电站之间的连接不包括在内；d) 工厂、工业厂或其他工业、农业、商业或公共场地的电气系统；e) 用于发电、输电、配电和/或存储电力的离岸设施上的电气power installation；f) 过渡塔/杆（架空线路和地下线路之间）。电气power installation包括以下设备：旋转电气机器；开关设备；变压器和电抗器；变流器；电缆；接线系统；电池；电容器；接地系统；属于封闭电气操作区一部分的建筑物和围栏；相关的保护、控制和辅助系统；大型空心电抗器。注意1：通常，设备标准优先于本文件的要求。本文件不适用于以下各项的设计和建设：不同电气power installation之间的架空和地下线路；电气化铁路轨道和车辆；采矿设备和安装；荧光灯安装；根据IEC 60092（所有部分）和IEC 61892（所有部分）用于海上石油工业的钻井、加工和储存目的的船舶和离岸装置上的安装；静电设备（例如静电除尘器、喷漆单元）；测试站；医疗设备，例如医用X射线设备。本文件不适用于预制、型式测试开关设备和高压/低压预制变电站的设计，这些设备已有单独的IEC标准。注意2：本文件的范围不包括在电气power installation上进行带电作业的要求。注意3：本文件的范围考虑了高压安装的安全要求以及高压安装对低压安装的影响。对于1 kV及以下的电气安装，适用IEC 60364（所有部分）。 [外文原描述]： IEC 61936-1:2021 provides requirements for the design and the erection of electrical power installations in systems with nominal voltages exceeding 1 kV AC and nominal frequency up to and including 60 Hz, so as to provide safety and proper functioning for the use intended. This document does not apply to the design and erection of any of the following: – overhead and underground lines between separate electrical power installations; – electrified railway tracks and rolling stock; – mining equipment and installations; – fluorescent lamp installations; – installations on ships according to IEC 60092 (all parts) and offshore units according to IEC 61892 (all parts), 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. This document does not apply to the design of prefabricated, type-tested switchgear and high voltage/low voltage prefabricated substation, for which separate IEC standards exist. This edition includes the following significant technical changes with respect to the previous edition: introduction has been rewritten to reflect the status when this document is produced; the scope has been improved to clarify the application of this document; missing and obsolete terms and definitions have been updated including improvement of existing terms; Table 1 has been updated where agreements between supplier and user are needed; requirements of electromagnetic compatibility have been clarified; insulation coordination clause (Clause 5) has improved wording for better clarity and the technical content has an updated coordination to the latest versions of the insulation coordination standards; wording regarding electrical equipment has been improved and made clearer; subclause for fuses has been improved and reworded; requirements have been added for labelling when multiple sources are required to be disconnected; missing requirements for GIS have been reintroduced; subclause regarding ventilation (HVAC) has been improved; figures in Clause 7 have been updated and moved to the corresponding subclause; requirements for transformer installations have been improved including adjustment of editorial typing-errors; clause on protection, automation and auxiliary systems has been restructured and improved; protection against lightning strokes has been extended; clarification of content due to the distinction between erection (and providing electrical safety for the intended use of the electrical power installation) and subsequent activities such as maintenance and repair with safe working procedures; where no provincial, national or regional regulations are available for safe working procedures, an informative guideline is provided in Annex F. This replaces the former parts of Figure 3 in Clause 7.
