摘要
高速铁路车站出现多次电气化牵引电流回流造成机械绝缘节和钢轨损伤的现象。根据现场的几次典型案例,对比分析电压损伤和电流灼伤2种情况的不同,为后续针对性的研究防护措施提供参考。
Repeated burns caused by traction current backflow have occurred to rail mechanical insulation joints and rail within high-speed railway stations.Based on several typical field cases,we contrast the differences of voltage injuries and current injuries,providing a reference for future study aimed at seeking out protection measures.
