查询词典 electron volt

Then the error sources of the reaction type and electron type electric energy mete were analyzed and the theory analysis result through the concrete test have been proved. At last, the main conclusion has been drawn. When the induction type electric energy meter measures harmonics energy, the negative error characteristic appears. The higher the frequency of harmonics is, the greater the error is. The electron type electric energy meter can measure harmonics energy accurately in general cases. Except thermo-electrical conversion type electron type power meter, reaction type and electron type electric energy meter can measure direct current power.

本论文通过分析感应式和电子式电能表的工作原理推导出了电能表计量电能的数学模型；分析了感应式和电子式电能表的误差来源以及谐波对计量的影响，并通过具体的试验对理论分析结果进行了验证；得出了如下谐波对电能表计量影响的主要结论：感应式电能表计量谐波电能时，呈现负的误差特性，谐波频率越高，误差越大；电子式电能表在其频响范围内可以准确计量谐波电能。
