摘要
为了更好地了解济宁地区LED照明产品的整体质量情况及动态变化情况,本文通过对济宁县市区照明灯具市场及大型商超进行随机抽样检测的方法,对2021—2023年济宁流通领域中LED照明产品进行抽样检测,并对抽检结果进行了分析研究。通过对抽检数据进行统计和分析,发现济宁地区流通领域LED照明产品的电磁骚扰水平整体较好,存在的问题主要集中在骚扰电压和谐波电流发射项目上,总谐波电流畸变率(I-THD)普遍偏高。
In order to better understand the overall quality and dynamic changes of LED lighting products in the Jining area,this paper conducts random sampling testing on the lighting fixture market and large supermarkets in the urban area of Jining,and conducts sampling testing on LED lighting products in the distribution field of Jining from 2021 to 2023.The sampling results are analyzed and studied.Through the statistics and analysis of sampling data,it is found that the overall level of electromagnetic interference in LED lighting products in the circulation field of Jining area is relatively good.The problems mainly are the disturbance voltage and harmonic current emission projects,and the total harmonic current distortion rate(I-THD)is generally high.
