中文摘要:

电网中的电流直流分量会对低压电流互感器的计量特性产生影响,通过模拟含直流分量的正弦半波电流波形,对被试样品进行试验,分别研究半波电流峰值和直流分量大小对低压电流互感器计量特性的影响。试验表明：电流互感器一次侧电流中含有的直流分量会使二次侧电流发生畸变,其畸变程度既和一次侧电流中所含的直流分量大小有关,也和一次侧电流的峰值有关。

英文摘要:

Based on the simulation of half-wave current which includes dc component and the experiment on the samples of the participants, the influence on the measurement characteristics of low-voltage current transformer caused by the peak value of half-wave current and dc component is studied in this paper. The experiment shows that the dc component of the current in primary side of low-voltage current transformer would results in the distortion of current in secondary side, and the distortion degree relates to the value of the dc component and also the peak value of current in primary side.
