摘要
谐波电流超标不仅造成电能效率降低,灯具发热量增大,更会影响公用电网的供电质量。对市售几款有中国强制认证(CCC)标志的低功率LED照明产品的谐波电流进行检测,将各次谐波电流测量值与IEC 61000-3-2:2018谐波电流限值规定进行比对,揭示我国低功率照明产品普遍存在着谐波电流超标的问题,并对LED照明灯具谐波电流超标的主要原因(开关电源)进行分析。希望为LED照明设备厂家及消费者产生一定的积极影响。
Excessive harmonic current will not only reduce the power efficiency, increase the heat generation of the lamps, but also affect the power supply quality of the public grid. In this article, a comparison is made based on the measured harmonic currents obtained from the detection of LED lighting products with China Compulsory Certification(CCC) mark and the harmonic current limits specified in IEC 61000-3-2, revealing that the harmonic currents of low power lighting products in my country commonly exceed the standard. And the main reason(switching power supply) of the harmonic current generated by LED lighting lamp is analyzed. Hope it has a certain positive impact for LED lighting equipment manufacturers and consumers.
