标准摘要
[中文适用范围]： IEC 61000的这一部分涉及对公共低压系统施加的电压波动和闪烁的限制。它规定了在特定条件下测试的设备可能产生的电压变化的限值，并给出了评估方法的指导。 IEC 61000的本部分适用于每相输入电流等于或小于16 A的电气和电子设备，旨在连接到50 Hz、220 V至250 V线对中性点之间的公共低压配电系统，并且不受条件连接的限制。当使用 6.4 的参考阻抗 Zref 进行测试时，不符合 IEC 61000 本部分限制的设备，因此不能声明符合本部分，可重新测试或评估以表明符合 IEC 61000-3-11 。第3-11部分适用于每相额定输入电流≤75A且有条件连接的设备。本部分规定的试验为型式试验。具体的测试条件在附录 A 中给出，测试电路如图 1 所示。 注：IEC 61000 这部分的限制主要基于 230 V/60 W 线圈灯丝灯光闪烁的主观严重程度灯受电源电压波动的影响。对于标称电压低于 220 V 线对中性线和/或频率为 60 Hz 的系统，正在考虑限制和参考电路值。 [外文原描述]： IEC 61000-3-3:2008 is concerned with the limitation of voltage fluctuations and flicker impressed on the public low-voltage system. It specifies limits of voltage changes which may be produced by an equipment tested under specified conditions and gives guidance on methods of assessment. This part of IEC 61000 is applicable to electrical and electronic equipment having an input current equal to or less than 16 A per phase, intended to be connected to public low-voltage distribution systems of between 220 V and 250 V line to neutral at 50 Hz, and not subject to conditional connection. The tests according to this part are type tests. Particular test conditions are given in annex A and the test circuit is shown in Figure 1. This second edition IEC 61000-3-3 cancels and replaces the first edition published in 1994, amendment 1 (2001) and amendment 2 (2005). This edition constitutes a revised edition.
