摘要
接触网处于外部自然环境中,低温天气下覆冰会使接触网形状发生变化,在风的作用下极易发生舞动现象。接触网覆冰舞动不能满足受电弓取流要求,严重影响电气化铁路运行安全。针对近年来接触网覆冰舞动造成接触网设备损坏,对接触网覆冰舞动灾害提出改进措施;分析接触网除冰技术,探索将其应用于防范接触网覆冰舞动灾害事故的可行性。
OCS locates in the external natural environment,its shape will change along with ice coating under low temperature,and the galloping phenomenon will occur under the wind action.The current collection by pantograph is unable to be met satisfactorily due to OCS galloping,seriously threatening the safety of electrified railway transportation.With regard to the damage of OCS equipment caused by icing and galloping of OCS in recent years,improving measures against the disaster of OCS galloping are proposed.And OCS de-icing technologies are analyzed and the feasibility of application of these technologies for prevention of accidents caused by icing and galloping of OCS.
