摘要弓网电弧等离子体具有高温度、高能量的特点,对高速铁路弓网电接触的性能造成了威胁。基于弓网电弧模拟实验平台,利用光谱诊断法对弓网电弧等离子体进行研究。对辐射的主要特征谱线进行标识和归属,并计算弓网电弧等离子体的激发温度、转动温度、振动温度和电子密度。此外,还研究了电源输出电流对激发温度和电子密度的影响。实验结果表明,弓网电弧等离子体对接触网铜导线和浸金属碳滑板强烈的烧蚀作用会产生丰富的铜原子谱线、铁原子谱线和CN B²∑⁺→X²∑⁺谱线。同时,基于Boltzmann斜线法,发现了弓网电弧等离子体激发温度随电流的增加而增加。通过拟合电弧等离子体中CN B²∑⁺→X²∑⁺谱线,可知在30A电流条件下,弓网电弧等离子体的转动温度和振动温度分别达到6 800K和9 000K。最后,讨论了特征谱线的展宽机制,并利用Cu I 521.82nm谱线,探讨了弓网电弧等离子体的电子密度随电流的增加而上升的情况。

Abstract：Pantograph-catenary arc plasma, with high temperature and high energy density, can severely threaten the electrical contact performance of pantograph-catenary system in high speed railway. In this paper, pantograph-catenary arc experiments were conducted based on arc simulative platform in laboratory. The characteristic of pantograph-catenary arc plasma was studied by spectral diagnosis method, and then the primary characteristic lines were recognized and classified. The excitation temperature, rotational temperature, vibrational temperature and electron density were also calculated, respectively. Meanwhile, the influence of input current on excitation temperature and electron density was analyzed. The results show that abundant copper, iron and CN B²∑⁺→X²∑⁺ characteristic lines would occur due to the intense erosion effects of pantograph-catenary arc plasma on copper wire and metal impregnated strips. In addition, it is found that the excitation temperature of pantograph-catenary arc plasma increases with the increase of current based on Boltzmann plot. The rotational temperature and vibrational temperature reach up to 6 800K and 9 000K respectively when the current is 30A, according to the theoretical calculation with the spectral line of CN B²∑⁺→X²∑⁺. Furthermore, the broadening mechanism of characteristic lines was discussed, and by Cu I 521.82nm characteristic line the increasing tendency of electron density with the input current was analyzed.

Key words： Pantograph-catenary arc plasma, emission spectrum, excitation temperature, rotational temperature, vibration temperature
