| 摘 要： | 频繁发生的覆冰事故对发展迅速的电气化铁路接触网的影响逐渐凸显.基于对线路覆冰形成条件和机理的分析,在人工环境室中模拟覆冰时的大气条件对接触线覆冰进行了实验研究,通过改变气温、风速以及空气中液态水含量等气象参数,得到不同气象参数对接触网覆冰增长的影响以及覆冰类型的转变规律,实验结果对于预防接触网覆冰及指导接触网融冰有着重要意义. |

| Abstract: | The impact of frequent icing accidents on the contact wire system is becoming more and more evident with rapid development of the electrified railway.Based on the analysis of icing conditions and generation mechanism,an experimental investigation in an artificial environment room was conducted to determine the characteristics of icing on a contact wire.Extensive measurements were made for a variety of conditions including airsteam velocity,liquid water content,initial droplet temperature,and mass flow rate ... |
| Keywords: | icing contact wire experimental study |
