多表位直流电能表自动检定装置的研制
|
摘要
为满足日益增长的分布式直流电源、直流负荷及直流电能检定的需求,本文研制了一种多表位直流电能表自动检定装置。文中讲述了检定原理、硬件设计和软件设计,并对检定装置进行了重复性试验、稳定性试验和测量不确定度评定。试验结果表明,该检定装置量值稳定、精度高,检定结果符合国家相关检定规程要求,具有广泛的应用前景。
In order to meet the increasing demand of distributed DC power supply, DC load andDC power verification, a multi-epitope DC electric energy meter automatic verification device isdeveloped. The verification principle, hardware design and software design are given, and therepeatability test, stability test and uncertainty evaluation of the calibration device are also carried out.The test results show that the calibration device has stable measurement value and high accuracy, andthe calibration results meet the requirements of the relevant national verification regulations. It has wideapplication prospects.
