接触网是牵引供电系统的重要组成部分,是电气化铁路所特有的、为电力机车或动车组提供电能的特殊供电线路,是列车运行的关键设备,对铁路运输有着重要作用。由于其结构特殊且无备用以及运行环境的复杂,其发生故障的频率高、形式多样。在发生接触网故障跳闸时,运用科学的手段对故障情况进行正确的分析判断,对于接触网运行检修人员制定合理的抢修方案有很强的指导意义,同时在故障原因判明后,正确而又有效的处置措施,对于铁路牵引供电的及时恢复也起到关键性作用。
Catenary is an important part of traction power supply system. It is a special power supply line that is unique to electrified railway and provides electric power for electric locomotive or EMU. It is the key equipment for train operation and plays an important role in railway transport. Due to its special structure and no spare and the complexity of the operating environment, the frequency of its failure is high, in various forms. In the event of a contact network fault trip, the use of scientific means to correctly analyze the situation of the fault analysis, for the operation of the contact network operators to develop a reasonable repair program has a strong guiding significance, while the cause of the malfunction identified, correct and effective Of the disposal measures for the timely recovery of rail traction power supply also played a key role.
