Abstract

Abstract: In view of the EMU with CTCS3-300S on-board ATP that has the problem of two disconnections in neutral section found during integrated commissioning and test (ICT) of signaling system, this paper carries out a multi-angle study in combination with the interpretation of the principle in neutral section, the cause of test problem, and the discussion of industry standards. In the end, the paper identifies the cause of the problem, and considers the method of ICT and the source of design specification.

Key words: high-speed railway, neutral section, on-board ATP, magnetic steel, ICT

摘要： 针对信号系统联调联试互联互通测试期间发现的装载有CTCS3-300S车载ATP的动车组在过分相时存在两次断主断问题，结合过分相原理解读、试验问题原因查找、行业规范探讨等方面进行多角度研究。最终锁定问题原因，并对联调联试方法以及设计规范源头问题进行思考。
