摘要冲击高压信号为幅值高、持续时间短、频率覆盖范围宽的单次脉冲波形,电压转换装置受分布参数的影响,其刻度因数难以直接溯源至现有的国家基准或标准量值。提出一种基于多频率分量加权叠加的冲击电压刻度因数评估方法。根据帕萨瓦尔定理,针对冲击电压转换装置,建立冲击刻度因数与多频率交流刻度因数之间的函数关系,将暂态的、单次的波形刻度因数溯源难题转化为稳态的、周期的交流刻度因数获取与频段权重计算的问题,通过分析该评估方法的计算误差优于0.05%。最后提出了基于该评估方法的实施方法,开展了基于标准电容分压器的计算验证,其扩展不确定度优于0.02%。结果表明,基于多频率分量加权叠加的冲击电压刻度因数评估方法能够准确评估冲击电压转换装置的冲击刻度因数并具有电学计量手段上的可行性和可操作性。

Abstract：To ensure the uniformity of the values of impulse voltage parameters in China, a method for synthesizing impulse voltage scale factors based on multi frequency component weighting is proposed.According to the Parseval’s theorem, a functional relationship between the impulse scale factor and the AC scale factor is established for the impulse voltage conversion device.The problem of tracing the transient and single waveform scale factor is transformed into the problem of obtaining the steady-state and periodic AC scale factor and calculating the frequency band weight.At the same time, the calculation error of the proposed evaluation method is better than 0.05% through analysis.Finally, an implementation method based on the mentioned synthesis method is proposed, and calculation validation based on the standard capacitor voltage divider is carried out, which expanded uncertainty is better than 0.02%.The results show that the proposed method for synthesizing the scale factor of impulse voltage based on multi frequency component weighting can accurately calculate the scale factor of impulse voltage.

Key words： electrical metrology impulse voltage scale factor;traceability voltage conversion device frequency decomposition wighted superposition
