多功能设备谐波电流测试方法及其在IEC 61000-3-2标准中的应用

摘要

研究在IEC 61000-3-2:2014标准中增加技术条款,以适应新近出现的多功能设备的谐波电流发射测试.分析多功能设备的定义和分类问题,给出其相应的定义及分类建议.根据现版IEC标准的技术要求,对多功能设备的谐波电流检测技术要求进行分析.对3种多功能设备样品的测试数据和结果进行分析,讨论现行标准对多功能设备的谐波电流测试可能存在的问题,提出针对这些问题的修改建议.按照IEC 61000-3-2标准技术条款的格式等要求,形成该标准的修正文件内容,为今后的标准修订提供参考.%Technical clauses in IEC 61000-3-2:2014 standard for new type of multi-functional equipment (MFE) are studied. The definition and the classification of equipment for MFE are analyzed,and the subsequent results are also provided. According to the technical requirement in the updated IEC standard, the setup of harmonic current emission testing for MFE is analyzed. Meanwhile,the problems related to the MFE are discussed. The amendments for harmonic current testing related to MFE are provided, which are documented in the form of IEC 61000-3-2 and could be used for the formal standard amendment file in the future.
