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。谐波分量根据附录 A 和 B 进行测量。IEC 61000 的这一部分适用于输入电流高达每相 16 A（含）且打算连接到公共低压配电系统的电气和电子设备。本标准包括输入电流每相 16 A（含）以下的非专业设备@的弧焊设备。 IEC 60974-1@ 中规定的专业用途的弧焊设备不包括在本标准中，并且可能受到 IEC/TR 61000-3-4 或 IEC 61000-3-12 中规定的安装限制。按照本标准进行的试验为型式试验。附件 C 中给出了特定设备的测试条件。对于标称电压低于 220 V（线对中性点）@的系统，尚未考虑这些限制。注：本标准中使用了词语“appliance@appliance@device”和“equipment”。对于本标准而言，它们具有相同的含义。 [外文原描述]： IEC 61000-3-2:2014 deals with the limitation of harmonic currents injected into the public supply system. It specifies limits of harmonic components of the input current which may be produced by equipment tested under specified conditions. It is applicable to electrical and electronic equipment having an 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 input current up to and including 16 A per phase, is included in this standard. Arc welding equipment intended for professional use, as specified in IEC 60974-1, is excluded from this standard and may be subject to installation restrictions as indicated in IEC/TR 61000-3-4 or IEC 61000-3-12. The tests according to this standard are type tests. Test conditions for particular equipment are given in Annex C. For systems with nominal voltages less than 220 V (line-to-neutral), the limits have not yet been considered. This fourth edition cancels and replaces the third edition published in 2005, Amendment 1:2008, Amendment 2:2009 and Corrigendum of August 2009. This edition includes the following significant technical changes with respect to the previous edition: - a clarification of the repeatability and reproducibility of measurements; - a more accurate specification of the general test conditions for information technology equipment; - the addition of optional test conditions for information technology equipment with external power supplies or battery chargers; - the addition of a simplified test method for equipment that undergoes minor changes or updates; - an update of the test conditions for washing machines; - a clarification of the requirements for Class C equipment with active input power ≤ 25 W; - an update of the test conditions for audio amplifiers; - a clarification of the test conditions for lamps; - an update of the test conditions for vacuum cleaners; - the addition of test conditions for high pressure cleaners; - an update of the test conditions for arc welding equipment; - the reclassification of refrigerators and freezers with variable-speed drives into Class D; - and the addition of test conditions for refrigerators and freezers.
