弓网燃弧问题分析及对策探讨

电力机车通过受电弓与接触网的耦合获得不间断电能,电能的可靠传输关乎高速铁路的运营效率和安全。随着电气化铁路运营速度的提升,弓网燃弧问题已成为制约牵引电能传输可靠性的关键因素之一。现有关于弓网燃弧研究成果多侧重于电气理论,与实际运营结合不够紧密。本文主要从动态检测燃弧问题着手,对燃弧缺陷产生原因进行探讨,并结合运营实践经验对弓网燃弧问题的改善提出建议。

The electric locomotives obtain the uninterrupted power supply through the coupling of pantograph and catenary,and the reliable transmission of electric energy is related to the operation efficiency and safety of the high-speed railways.Along with the improvement of running speed of electrified railways,the arcing problems between pantograph and catenary has become one of the key factors restricting the reliability of traction power transmission.The existing research results on arcing between pantograph and catenary mainly focus on electrical theory and are not closely integrated with the actual operation.The paper,starting from the arcing problem occurred in dynamic inspection,discusses the causes of generating of arcing defects,puts forward proposals on improving of problems of arcing between pantograph and catenary with connection to the actual operation experience.
