摘　　要：针对低压电流互感器自动化检定系统周期内停机送检问题,提出了一种低压电流互感器自动化检定系统在线计量检测的方法.利用传递标准和核查标准在主持实验室与参加实验室之间进行量值传递,从基本误差、重复性、一致性、误检率和错检率五个方面进行量值溯源,通过休哈特控制图实时反馈检测误差数据,实现自动化检定系统的在线量值溯源和在线计量监督.结果表明,该方法避免了自动化检定系统的拆卸和送检过程,有效地提高了工作效率.Aiming at the problem that the automatic testing system of low-voltage current transformer needs to be shut down and transported for inspection in a period,an online measurement and detection method for the automatic testing system of low-voltage current transformer was proposed.By using both transfer and inspection standards,the measurement values were transferred between the hosting and the participating laboratories.The measurement values were traced from five aspects including basic errors,repeatability,consistency,miss detection rate and false detection rate,and the feedback of detection error data was completed in real time through a Shewhart control chart so as to realize the traceability and supervision of online measurement for automatic testing system.The results show that the as-proposed method dispenses with the disassembly and transport process for the inspection of automatic testing system and improves the work efficiency availably.
