恶劣气候对电气化铁路接触网的影响与对策

The Effect and Countermeasure of Atrocious Weather in Overhead Catenary of Electrified Railway

恶劣气候对电气化铁路接触网设备安全稳定运行构成了严重威胁。在总结复杂大气环境下典型设备故障的基础上,对覆冰、大风及污秽等恶劣气候导致接触网故障的根本原因进行了全面分析,并提出了相应的防治对策和方法,以期为电气化铁路接触网设备设计和运行维护部门的防灾减灾工作提供借鉴和参考。

Atrocious weather poses great danger to the safe and stable operation of equipment in overhead catenary of electrified railway.On the basis of summarizing typical failure of equipment under complicated atmospheric environment,the root cause of external insulation faults of electrified catenary are analyzed comprehensively,such as icing,windstorm and pollution.Meanwhile,the countermeasures and advices are put forward,which is expected to provide reference for the design of equipment in overhead catenary of electrified railway and the disaster prevention and mitigation work of operation and maintenance department.
