标准摘要
[中文适用范围]: IEC 1000-2 的这一部分涉及频率范围高达 10 kHz 的传导骚扰以及电源信号系统的扩展。单独的部分给出了不同系统电压级别的数字兼容性级别。本节不涉及应用兼容性级别来评估@例如@来自特定设备或装置的允许干扰发射@因为其他系统参数@例如其阻抗作为频率的函数@也必须被考虑。此外,它不会预先判断产品委员会的抗扰等级规范,而只是提供指导。考虑的干扰现象有: - 谐波; - 间谐波; - 电压波动; - 电压暂降和短时供电中断; - 电压不平衡;- 主电源信号;- 电源频率变化;- 直流分量。本节的目的是提供有关公共供电系统上可能出现的各种类型干扰的信息。它是那些给出兼容性级别值的相关部件的参考文档。 [外文原描述]: Has the status of a technical report, and gives information on the various types of disturbances that can be expected on public power supply systems. The following disturbance phenomena are considered: - harmonics - inter-harmonics - voltage fluctuations - voltage dips and short supply interruptions - voltage unbalance - mains signalling - power frequency variation - d.c. components.
