弓网燃弧检测方法及评价标准研讨

Study on Inspection Methods and Evaluation Criteria for Pantograph-catenary Arcing

对弓网燃弧现象进行机理分析,总结不同检测方法优缺点,对比国内外现有弓网燃弧评价标准并分析了差异性;针对30%牵引电流的限制评价条件的影响因素进行了研讨,给出了我国弓网燃弧检测的典型应用案例,指出目前我国采用的标准不考虑牵引电流的影响更为科学、全面、合理。

The paper analyzes the mechanism of pantograph-catenary arcing,summarizes the advantages and disadvantages of various inspection methods,compares the evaluation criteria of pantograph-catenary arcing at home and abroad,and analyzes their differences,studies the influencing factors limiting the evaluation conditions with regard to 30%of the traction current,puts forward the typical application cases for pantograph-catenary arcing inspection,points out that the criteria adopted by our country,which do not take into account of the influence of traction current,are more scientific,comprehensive and reasonable.
