交流接触器线圈功率损耗测量结果的不确定度评定

Uncertainty Evaluation of Coil Power Consumption Measurement Result for AC Contactor

按照IEC 60947 4-1:2012标准《低压开关设备和控制设备第4-1部分:接触器和电动机起动器机电式接触器和电动机起动器(含电动机保护器)》的检定规程,依据JJF 1059.1—2012《测量不确定度评定与表示》的标准规定,对低压电器类交流接触器的线圈功率损耗测量结果的不确定度进行了详细评定。通过对标准不确定度、合成不确定度以及扩展不确定度的评定,给予了明确的阐述。

According to the test procedure of IEC 60947-4-1 ： 2012 u Low voltage switchgear and controlgear-Part 4-1 ： Contactors and motor-starters-Electromechanical contactors and motor-starters ” , the uncertainty of coilpower consumption measurement result for alternating current contactor is specified based on the requirements of JJF1059. 1 -2012 u Evaluation and expression of uncertainty in m easurem ent; meanwhile the evaluation of standarduncertainty, combined uncertainty and expanded uncertainty are also clarified clearly.
