对高速铁路动车组停在接触网分相区内救援办法的探讨

Discussion on Rescue Scheme for High-speed EMU Stopping in the Catenary Phase Splitting Section

高速铁路电分相采用锚段关节式电分相后,由于中性段长度较器件式增长,动车组停在分相区的概率大大增加,给动车组停在电分相无电区时的救援工作带来新的问题。根据我国已开通运营的京津、武广、郑西高速铁路关节式电分相结构,探讨动车组停在分相无电区后利用接触网开关救援办法,并对完善我国高速电气化铁路电分相设计提出建议。

Because high-speed railway adopts overlap phase splitting,the neutral section is longer than that of the mode of part,the probability that EMU stops in the catenary phase splitting section increases significantly,which brings new questions for the EMU rescue.According to the overlap phase splitting structure of Beijing-Tianjin,Wuhan-Guangzhou,Zhengzhou-Xi＇an high-speed railway that are put into operation,the authors discuss the method used to rescue EMUs stopping in the phase splitting and no-electricity section by taking advantage of catenary switches,also give suggestions on perfecting the design of phase splitting in China electrified high-speed railways.
