标准摘要
[中文适用范围]： IEC 61000-4-34:2005+AMD1:2009+AMD2:2025 CSV 规定了连接到低压供电网络的电气和电子设备在电压骤降、短时中断和电压变化情况下的抗扰度测试方法和推荐的测试等级范围。本标准适用于额定输入电流每相超过16 A的电气和电子设备。它涵盖了住宅区安装的设备以及工业机械，特别是连接到50 Hz或60 Hz交流电网（包括单相和三相电源）的设备的电压骤降和短时中断情况。本标准的目的是为评估电气和电子设备在受到电压骤降、短时中断和电压变化影响时的抗扰度建立一个共同的参考标准。IEC 61000的本部分所记录的测试方法描述了一种一致的方法，用于评估设备或系统对特定现象的抗扰度。根据IEC指南107，本标准具有基本电磁兼容（EMC）出版物的地位。 [外文原描述]： IEC 61000-4-34:2005+AMD1:2009+AMD2:2025 CSV defines the immunity test methods and range of preferred test levels for electrical and electronic equipment connected to low-voltage power supply networks for voltage dips, short interruptions, and voltage variations. This standard applies to electrical and electronic equipment having a rated input current exceeding 16 A per phase. It covers equipment installed in residential areas as well as industrial machinery, specifically voltage dips and short interruptions for equipment connected to either 50 Hz or 60 Hz a.c. networks, including 1-phase and 3-phase mains. The object of this standard is to establish a common reference for evaluating the immunity of electrical and electronic equipment when subjected to voltage dips, short interruptions and voltage variations. The test method documented in this part of IEC 61000 describes a consistent method to assess the immunity of equipment or a system against a defined phenomenon. It has the status of a Basic EMC Publication in accordance with IEC Guide 107.
