关于GB 17625.1-2022标准照明设备部分谐波电流试验解析

Analysis of Harmonic Current Test of Lighting Equipment in GB 17625.1-2022

GB 17625.1—2022电磁兼容限值第1部分:偕被电流发射限值(设备每相输入电流≤16A)将于2024年7月1日正式实施,与GB 17625.1—2012相比,照明设备部分试验方法和限值要求变动较大。为便于检测机构、研发人员、生产厂家等更好地理解与掌握标准,本文主要从照明设备相关的试验方法、试验步骤和试验结果的判定等进行说明,并以相应的灯具为例予以解析。

GB 17625.1-2022 Electromagnetic compatibility—Limits—Part 1:Limits for harmonic current emissions(equipment input current≤16 A per phase)will be officially implemented on July 1,2024.Compared with GB 17625.1-2012,there are great changes in testing methods and limit requirements for lighting equipment.In order to facilitate testing institutions,R&D personnel and manufacturers to better understand and master the standard,the paper mainly introduces the testing methods,procedures,determination of test results,and relevant aspects of lighting equipment,and analyzes them taking corresponding lamps as examples.
