电磁兼容性（EMC）第3-2部分:限值谐波电流发射限值（设备输入电流）≤每相16安）

[中文适用范围]： 本部分IEC 61000涉及限制注入公共供电系统的谐波电流。 它规定了在特定条件下测试的设备可能产生的输入电流谐波分量的限制。 谐波分量根据附录A和B进行测量。 本部分IEC 61000适用于每相额定输入电流不超过16A的电气和电子设备，并打算连接到公共低压配电系统。 非专业设备的弧焊设备，每相额定输入电流不超过16A，包含在本文件中。 根据IEC 60974-1规定的专业用途的弧焊设备不包括在本文件中，并可能受到IEC/TR-61000-3-4或IEC 61000-3-12中规定的安装限制。 根据本文件的测试是型式测试。特定设备的测试条件在附录C中给出。 对于标称电压小于但不等于220V（线对中性）的系统，尚未考虑限制。 注：本文件中使用的术语装置、器具、设备和装置在本文件中具有相同的含义。 [外文原描述]： IEC 61000-3-2:2018 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 61000-3-2:2018 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.
