电磁兼容性(EMC).第3-2部分:极限值.谐波电流辐射的极限值(设备输入电流不大于16A/相)

[中文适用范围]： IEC 61000 的这一部分涉及注入公共供电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。 IEC 61000的这一部分适用于每相额定输入电流不超过16A且旨在连接到公共低压配电系统的电气和电子设备。本文件中包含非专业设备的弧焊设备，其额定输入电流每相不超过 16 A。 IEC 60974-1 中规定的专业用途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（线电压）的系统，尚未考虑这些限制。注：本文件中使用了“装置”、“器具”、“装置”和“设备”等词语。对于本文档而言，它们具有相同的含义。 [外文原描述]： 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.
