摘　　要：通过在单相电能表检定流水线进行检定实验的同时,使用标准电能表副表实现对标准电能表主表的实时核查。利用被核查的标准电能表主表的最大允许误差和校准证书上给出的校准结果不确定度,绘制核查控制图,可以在线直观的反映被核查的标准电能表主表的实际误差值的变化大小和方向。设置误差警戒线,分析设置适用生产工作情况的误差警戒线,对标准电能表主表实际误差值做更精确的掌握,为标准电能表主表的维护提供了更好的支撑。同时核查结果可以为期间核查的一种补充。Simultaneously with the single-phase electric energy meter pipeline works,using the vice-standard to check the main standard.This paper used its maximum permissible errors,the calibration result and its uncertainty of the standard to be checked,thus one can determine a check measurement control chart,that one can make each check measurement result in figure intuitively reflect the error and change of direction and size of the standard which to be check.Set up the warning line and analyze the warning line which is suitable for production.A better grasp of the actual error value of the main standard provides and better support for the maintenance of the main standard.At the same time,the check results can be a supplement to the intermediate.
