摘 要:简要分析了中国客运专线的特点以及目前机车过分相方案存在的缺点。然后从系统构成、系统功能、工作原理以及运行试验等方面详细介绍了一种新型地面自动过分相系统。通过运行试验表明:该新型地面自动过分相系统能够保证动车组在各种运行工况条件下,切换开关合分闸引起的过电压不会造成绝缘破坏,合闸电涌不会造成保护误动;动车组进出中性段与切换开关合分闸瞬间不会影响对信号脉冲的判读,通过后能够自动恢复正常运行状态。Characteristics of Chinese PDL and disadvantages of current solution for over-phase system of locomotive are briefly analyzed and a new type ground auto over-phase system is introduced in details from the aspects of system composition, function, working prin- ciples and running test. The running test has shown that the new type auto over-phase system could ensure that the overvoltage caused by switching will not lead to damage to the insulation system and the switching inrush current will not result in protection malfunction in various working conditions~ entrance and exit of EMU into or from the neutral section or switching will not affect the judging of sig- nal impulse which will restore to normal working status after the locomotive passes by.
