摘要
GB 21518—2022《交流接触器能效限定值及能效等级》已于2022年12月29日经国家市场监督管理总局批准发布,于2024年1月1日正式实施。新标准正式实施后,满足新标准适用条件的,所有大陆境内生产、进口、销售的交流接触器产品必须满足新标准中能效规定值。在满足一定的条件下,生产企业可以自行根据标准测量吸持功率,评定能效等级。本文针对新标准中交流接触器线圈吸持功率的试验方法进行了详细整理分析,并根据标准要求进行了不确定评定,为广大交流接触器生产企业自行测量吸持功率提供了参考,引导交流接触器生产企业正确理解新标准中关于吸持功率的测量和如何分析吸持功率的不确定度。
GB 21518-2022,Minimum allowable values of energy efficiency and energy efficiency grades for AC contactors,was approved and released by the State Administration for Market Regulation on December 29,2022,and offi cially implemented on January 1,2024.After the new standard is offi cially implemented,all AC contactor products produced,imported,and sold in China's Mainland that meet the applicable conditions of the new standard must meet the energy effi ciency value specifi ed in the new standard.When certain conditions are met,manufacturers can measure the holding power according to standards and assess the energy effi ciency level.This paper sorts out and analyzes the test method of the holding power of AC contactors in the new standard,and conducts uncertainty assessment according to the requirements in the new standard,which provides a reference for the majority of AC contactor manufacturers to measure the holding power on their own and guides AC contactors manufacturers to correctly understand the measurement of holding power in the new standard and how to analyze the uncertainty of holding power.
