冻雨和覆冰对高速铁路接触网的危害及其防护

Hazards of Freezing Rain and Ice Coating on High Speed Railway Catenary and the Protection

接触网遭受冻雨和覆冰灾害,会严重影响其技术状态,进而影响弓网运行关系,造成高速铁路行车安全故障。一方面,要分析接触网覆冰的成因、危害,建立完备的工作预案,采取正确的运行策略。另一方面,要采用科学可靠的技术措施,增加相应的专用设备,实施有效的防冰和融冰。

The high-speed railway catenary suffers from the disasters of freezing rain and icing,which will seriously affect its technical condition,and then affect operation relationship between pantograph and catenary,resulting in high-speed railway safety accidents.On the one hand,it is necessary to analyze the causes and hazards of icing,establish complete work plans and adopt correct operation strategies.On the other hand,we need to adopt scientific and reliable technical measures,add relevant equipment and implement effective measures of anti-icing and de-icing.
