标准摘要
[中文适用范围]： 本部分 IEC 61000 涉及频率范围从 0 kHz 到 150 kHz 的传导电磁现象（干扰和来自公共低压供电系统的通信系统信号），针对特定通信系统延伸至 148.5 kHz。它规定了公共低压交流配电系统的兼容水平，其标称电压为单相高达 420 V，或三相高达 690 V，标称频率为 50 Hz 或 60 Hz。本文档中规定的兼容水平适用于公共耦合点。对于从上述系统接收供电的设备电源输入端，传导电磁干扰的严重程度在很大程度上可视为与公共耦合点处的水平相同。在某些情况下则不然，特别是对于专门供应特定安装的长线路，或对于设备所在安装内产生或放大的电磁现象的情况。规定了公共低压供电系统中可预期的传导电磁干扰现象的兼容水平，旨在指导定义：- 设置在公共供电系统中传导发射的限值（包括 3.1.5 中定义的规划水平）；- 产品委员会及其他组织为暴露在公共供电系统中存在的传导电磁现象的设备设定的抗扰度限值。 [外文原描述]： IEC 61000-2-2:2002+A1:2017+A2:2018 is concerned with conducted disturbances in the frequency range from 0 kHz to 9 kHz, with an extension up to 148,5 kHz specifically for mains signalling systems. It gives compatibility levels for public low voltage a.c. distribution systems having a nominal voltage up to 420 V, single-phase or 690 V, three-phase and a nominal frequency of 50 Hz or 60 Hz. Compatibility levels are specified for electromagnetic disturbances of the types which can be expected in public low voltage power supply systems, for guidance in: - the limits to be set for disturbance emission into public power supply systems; - the immunity limits to be set by product committees and others for the equipment exposed to the conducted disturbances present in public power supply systems. This consolidated version consists of the second edition (2002), its amendment 1 (2017) and its amendment 2 (2018). Therefore, no need to order amendment in addition to this publication.
