摘要
电力机车通过受电弓碳滑板与接触网动态滑动接触而获得电力。由于线路不平顺等原因,会造成弓网脱离接触,产生离线火花,即燃弧现象。进行燃弧检测对受电弓和接触网的日常维护都十分重要。基于燃弧的光学特性,利用图像处理处理技术判断燃弧并计算出燃弧单次持续时间和区段的离线率。研究结果表明,采用图像处理的方法可以有效的计算出较为准确的燃弧持续时间和离线率。能有效地评价弓网受流质量地性能。
Electric locomotive gets power from the dynamic sliding contact between pantograph carbon skateboard and catenary.As the rail surface is irregularity,the pantograph may lose contract with catenary and produce offline spark,namely arc phenomena.Arc test is important for routine maintenance of the pantograph and catenary.Based on the photo precipitation characteristics of the arc,the arc processing was judged by the image processing technique and the single duration of the arcing and the off-line rate of the section were calculated.The results show that the method of image processing can effectively calculate the accurate arcing duration and off-line rate.It can effectively evaluate the flow quality of the pantograph-catenary.
