IEC 61000-3-2:20 8+AMD1:2020+AMD2:2024 CSV涉及注入公共供应系统的谐波电流的限制。它规定了在规定条件下测试的设备可能产生的输入电流谐波分量的限值。它适用于每相额定输入电流高达并包括16A的电气和电子设备，旨在连接到公共低压配电系统。本文件包括每相额定输入电流不超过16 A（含16 A）的非专业设备的弧焊设备。IEC 60974-1中规定的用于专业用途的弧焊设备不包括在本文件中，并且可能受到IEC 61000-3-12中规定的安装限制。根据本文件进行的试验为型式试验。对于标称电压小于但不等于220 V（线路到中性线）的系统，尚未考虑这些限制。这第五版取消并取代了2014年出版的第四版。本版构成技术修订版。 与上一版相比，此版本包括以下重大技术变更: a)更新额定功率=25W的照明设备的排放限值，以考虑新型照明设备； b)增加5W的阈值，低于该阈值，所有照明设备均不适用排放限值； c)当操作非白炽灯时适用于调光器的要求的修改； d)增加数字负载侧传动控制装置的测试条件；e)取消使用参考灯和参考镇流器进行照明设备测试； f)用于照明设备的术语的简化和澄清； g)A类舞台灯光及演播室专业灯具的分类； h)关于应急照明设备分类的说明； i)对包括一个有效输入功率=2W的控制模块的照明设备的说明； j)电视接收机测试条件的更新； k)更新电磁炉的测试条件，同时考虑到其他类型的烹饪器具； l）为了与IEC 61000-3-12保持一致，将IEC 61000-3-2的范围从输入电流=16 A的设备变更为额定输入电流=16 A的设备。 2021年8月解释表的内容已包含在本副本中。仅适用于英文版本。 关键词:谐波电流

IEC 61000-3-2:2018+AMD1:2020+AMD2:2024 CSV deals with the limitation of harmonic currents injected into the public supply system. It specifies limits of harmonic components of the input current which can be produced by equipment tested under specified conditions. It is applicable to electrical and electronic equipment having a rated input current up to and including 16 A per phase, and intended to be connected to public low-voltage distribution systems. Arc welding equipment which is not professional equipment, with a rated input current up to and including 16 A per phase, is included in this document. Arc welding equipment intended for professional use, as specified in IEC 60974-1, is excluded from this document and can be subject to installation restrictions as indicated in IEC 61000-3-12. The tests according to this document are type tests. For systems with nominal voltages less than but not equal to 220 V (line-to-neutral), the limits have not yet been considered. This fifth edition cancels and replaces the fourth edition published in 2014. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) an update of the emission limits for lighting equipment with a rated power = 25 W to take into account new types of lighting equipment;
b) the addition of a threshold of 5 W under which no emission limits apply to all lighting equipment;
c) the modification of the requirements applying to the dimmers when operating non-incandescent lamps;
d) the addition of test conditions for digital load side transmission control devices;
e) the removal of the use of reference lamps and reference ballasts for the tests of lighting equipment;
f) the simplification and clarification of the terminology used for lighting equipment;
g) the classification of professional luminaires for stage lighting and studios under Class A;
h) a clarification about the classification of emergency lighting equipment;
i) a clarification for lighting equipment including one control module with an active input power = 2 W;
j) an update of the test conditions for television receivers;
k) an update of the test conditions for induction hobs, taking also into account the other types of cooking appliances;
l) for consistency with IEC 61000-3-12, a change of the scope of IEC 61000-3-2 from equipment with an input current = 16 A to equipment with a rated input current = 16 A.
