摘　　要：为了提高电气化铁路受电弓和接触网间能量传输的效率,需要有效抑制弓网系统中电弧的产生。通过分析弓网电弧的产生原因和影响因素,分别从优化设计、遵守材料及设备标准、提高施工精度、强化测试与检测要求和优化车载变压器等5个方面,阐述抑制接触网电弧的方法。结合国内外通用的电气化铁路设计规范,采取相关措施,以抑制电弧产生,保障电力机车的良好受流。In order to improve the efficiency of energy transferred from pantograph to catenary in electrified railway,it is necessary to decrease the arcing of pantograph-catenary system. After analyzing the causes and effects of arcing,five methods to reduce the arcing are expounded：design optimization,complying with the materials and equipment standards, improving the construction accuracy, strengthening requirements of testing and detection, and optimizing the on-board transformer. By combining with domestic and foreign common electrified railway design specifications,relevant measures used to decrease arcing are taken to ensure stability of locomotive current collection.
