Abstract: The progress of electrified railway transport industry can not be separated from the electrified railway power supply catenary. With the increasing improvement of the level of science and technology and the continuous improvement of train load, the early railway catenary structure can no longer conform to the contemporary trend at this stage, and it is very easy to produce various forms of hidden dangers. It seriously restricts the daily smooth operation of the railway and the personal and property safety of railway-related staff. There are many factors causing the problems of railway catenary, which generally include the problems caused by labor, weather, equipment itself and so on. Wenz provides different solutions and protection measures for various forms of problems, which can effectively avoid problems in the structure of railway catenary and ensure the smooth operation of electrified railway power supply.

引言
鐵路接触网构造是铺设在铁道上部的高压架空线,在铁道接触网中有非常关键的地位,然而铁路接触网长时间处于户外自然条件中,时常会遭到外部自然环境的制约和干扰,进而发生铁道接触网构造问题的情况,引起铁道运输大量经济财产消耗。鉴于此,本文对于铁道接触网产生的问题,给出合理的解决方案,以便降低铁道接触网发生安全隐患的概率,进而保障铁道运送活动的顺畅运行。
1 铁路接触网构造产生问题因素
1.1 大自然外界因素
铁路接触网构造长时间暴露于户外条件下,天气波动轻易就能对铁路接触网构造装置构成不良作用。在现实的作业过程中,如果发生打雷下雨状况亦或起雾天气,很大概率能导致铁路接触网遭到雷击,铁路列车车身可能出现由于断电故障的发生进而造成烧损阻隔问题,遭到损坏的周边自然条件也可能损坏铁路接触网构造。……
