摘要
基于弓网电弧模拟试验平台,分别利用可见光谱诊断方法对弓网电弧的辐射谱进行了初步研究,分析其特征谱线。由电弧辐射理论利用斜率法计算得出了电弧等离子体温度,并研究了不同运行状态下,弓网电弧等离子体的温度变化情况。结果表明:弓网电弧等离子体激发温度随着电流增大而增大,弓网间隙的增大也同样使温度增大。
The relationship between pantograph and catenary is one the of three key relationships of the safelyrunning high-speed railway,so it makes great sense in scientific research in theoretical and practical engineering.The radiation spectrums of pantograph-catenary arc were studied respectively, with the help of spectroscopy. Theradiation spectrums of arc plasma were collected by using spectrometer, its characteristic spectral lines were foundand the temperature of arc plasma was calculated through Bolezmann diagram method based on the theory of arcradiation. The changes of pantograph-catenary arc plasma temperature were studied under different running state.The results show that the temperature of pantograph-catenary arc is increasing with the increase of current and spacebetween pantograph and catenary.
