电力机车过电分相跳闸分析及预防措施的研究

对电力机车通过接触网电分相进行了过程分析,提出机车带电过电分相造成跳闸的主要原因为过电压和涌流.通过对新型机车断电过电分相时造成过电压的分析,从接触网、牵引变电所和机车结合部提出了防止跳闸和烧伤接触网的安全预防措施.

Analysis of Causes of Tripping during Electric Locomotive's Passage of Neutral Section and Study of its Prevention Measures

Analyzes the process of an electric locomotive passing a phase-break along the overhead contact system and concludes that over-voltage and inrush current are the major causes for tripping when a powered-on electric locomotive passes a phase-break. Safety and preventive measures are derived from the analysis on the over-voltage caused by a new generation power-off locomotive passing a phase-break to prevent tripping and burn damage to overhead contact system where overhead contact system, traction substation...
