高精度直流数字电压表的研制

Development of High Accuracy DC Digital Voltage Meter

介绍了三相电能表标准装置的组成和该装置中使用的高精度直流数字电压表的研制与开发。阐述了 0 .0 0 5级直流数字电压表的基本原理与技术性能 ,以及软、硬件特点。

Both the constitution of (0.01 class) three phase electric energy standard metrical set and the development of higy accuracy DC digital voltage meter applied to such electric energy standard metrical equipment are introduced in detail.The (0.005 class)meter's basic principle and specificaton including hard-ware and soft-ware are also described. The article can be served as a useful reference for establishment of three phase electric energy standard metrical equipment economically and reasonably.
