一种电子式电能表的新型误差调试方法

A new error debugging method for electronic watt-hour meter

传统的电子式电能表的误差调试方法,是通过人工的去改变电压网络的分压电阻来达到误差调试目的。这种误差调试方法效率低、误差精度差、手动操作复杂且安全性差。在目前人力成本不断提高的大环境下,这种调试方法显然不能采取。以新型计量芯片为基础,发明了一种新型的误差调试方法——功率调试法。实验结果表明,功率法调表效率高、精度高、没有安全隐患,并且颠覆了电子式电能表的生产模式。

Traditional error debugging method of electronic watt-hour meter is manually changing the divider resistance of voltage network to adjusting the errors. This method has disadvantage of low efficiency,poor error precision,complex manual operation and bad security. In the condition of the human costs are improving continuously,the old debugging method obviously can’t be adopted. Thus a new error debugging method of power debugging based on new metering chip is designed. Experimental results show that the power debugging method has high efficiency,high precision and no security risks,and subverts the produc-tion models of electronic watt-hour meter.
