标准范围

IEC 61936-1:20 10为标称电压高于1 kV交流电的系统中电力装置的设计和安装提供了通用规则。以及高达并包括60Hz的标称频率，以便为预期用途提供安全性和适当的功能。为了解释本标准，电力装置被认为是以下之一:a)变电所，包括铁路供电变电所；b)桅杆、电杆和塔上的电气装置；位于封闭电气操作区域之外的开关设备和/或变压器；c)位于单个站点上的一个(或多个)发电站。该装置包括发电机和变压器以及所有相关的开关设备和所有电气辅助系统。不包括位于不同站点的发电站之间的连接；d)工厂、工业厂房或其他工业、农业、商业或公共处所的电气系统。电力装置尤其包括以下设备:旋转电机；开关设备；变压器和电抗器；转换器；电缆；布线系统；电池；电容器；接地系统；作为封闭电气操作区域一部分的建筑物和围栏；相关的保护、控制和辅助系统；大型空心反应堆。注:一般来说，一项设备的标准优先于本标准。本标准不适用于下列任何一项的设计和安装:-独立装置之间的架空和地下线路；-电气化铁路；-采矿设备和装置；-荧光灯装置；-船上设施和近海设施；-静电设备（如静电除尘器、喷漆装置）；-试验场；-医疗设备，例如医疗X射线设备。本标准不适用于存在单独IEC标准的工厂制造、型式试验开关设备的设计。本标准不适用于在电气装置上进行带电作业的要求。第二版取消并取代了2002年出版的第一版。它构成技术修订。与上一版相比的主要变化如下:-制造商/承包商/规划者与用户/订购者/业主之间的附加协议的新参考表（4.1.2）；-增加了IEC未标准化但基于某些国家现行做法的空气中的最小间隙（附件A）；-删除标称电压(表1、表2、条款5)；-增加保险丝的规定(6.2.15)；-简化逃生路线的规定(7.5.4)；-删除操作通道的特别规定(7.5.4)；-修改消防净空（表3）；-修改接地系统的安全标准(10.2.1)；-允许接触电压的修改曲线（图12，附件B）；-删除没有标题的分条款的编号；-在许多情况下，将"should"改为"should"，或将带有"should"的子条款改为注释。2011年3月更正的内容已纳入本副本。

IEC 61936-1:2010 provides common rules for the design and the erection of electrical power installations in systems with nominal voltages above 1 kV a.c. and nominal frequency up to and including 60 Hz, so as to provide safety and proper functioning for the use intended. For the purpose of interpreting this standard, an electrical power installation is considered to be one of the following:
a) Substation, including substation for railway power supply;
b) Electrical installations on mast, pole and tower; Switchgear and/or transformers located outside a closed electrical operating area;
c) One (or more) power station(s) located on a single site. The installation includes generators and transformers with all associated switchgear and all electrical auxiliary systems. Connections between generating stations located on different sites are excluded;
d) The electrical system of a factory, industrial plant or other industrial, agricultural, commercial or public premises. The electrical power installation includes, among others, the following equipment: rotating electrical machines; switchgear; transformers and reactors; converters; cables; wiring systems; batteries; capacitors; earthing systems; buildings and fences which are part of a closed electrical operating area; associated protection, control and auxiliary systems; large air core reactor. NOTE: In general, a standard for an item of equipment takes precedence over this standard. This 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;
- fluorescent lamp installations;
- installations on ships and off-shore installations;
- electrostatic equipment (e.g. electrostatic precipitators, spray-painting units);
- test sites;
- medical equipment, e.g. medical X-ray equipment.
This standard does not apply to the design of factory-built, type-tested switchgear for which separate IEC standards exist. This standard does not apply to the requirements for carrying out live working on electrical installations. This second edition cancels and replaces the first edition, published in 2002. It constitutes a technical revision. The main changes with respect to the previous edition are listed below:
- new table of references for additional agreements between manufacturer/contractor/planer and user/orderer/owner (4.1.2);
- addition of minimum clearances in air not standardized by IEC but based on current practice in some countries (Annex A);
- deletion of nominal voltages (Table 1, Table 2, Clause 5);
- addition of regulations for fuses (6.2.15);
- simplification of regulations for escape routes (7.5.4);
- deletion of special regulations for operating aisles (7.5.4);
- modification of clearances for fire protection (Table 3);
- modification of safety criteria for earthing systems (10.2.1);
- modified curves of permissibly touch voltages (Figure 12, Annex B);
- deletion of numbering of subclauses without headlines;
- change of "should" to "shall" in many cases or change of subclauses with "should" to a note.The contents of the corrigendum of March 2011 have been included in this copy.
