随着我国电气化铁路的不断延伸和发展,接触网覆冰日益威胁着电气化铁路的安全运行。对于地处东北地区或其它寒冷地区的客运专线,因采用夜间停电综合维修方式,造成相当长的时间没有列车运行,气温较低时会造成接触导线出现覆冰现象。所以,探讨接触网覆冰的危害及研究接触网融冰的方法对铁路安全有着极为重要和深远的意义。
With the continuous extension and development of electrified railway in our country, the icing on the catenary network increasingly threatens the safe operation of the electrified railway. For passenger trains located in the northeast or other cold areas, due to the use of night power outage comprehensive maintenance, resulting in a long time no train operation, the temperature is low will cause the contact wire iced phenomenon. Therefore, it is extremely important and far-reaching for railway safety to explore the hazards of catenary ice and to study the ice melting of catenary.
