高速铁路区间轨道电路“红光带”故障处置方法与研究

Research and Treatment Method of "Red Light Band" Fault in Section Track Circuit of High Speed Railway

目前,高速铁路大量采用ZPW-2000K型无绝缘移频轨道电路制式,受维护质量、外部环境、器材特性等因素影响必然存在区间轨道电路"红光带"故障。轨道电路"红光带"故障对列车正常运输秩序干扰极大,且造成"红光带"故障的因素复杂,故障应急处置难度较大。本文针对这一问题进行分析探讨,充分运用信号集中监测调看结合网孔回路法综合分析,提出了应急处置分析方法,可为类似工程提供借鉴。

At present, ZPW-2000 k non-insulated frequency shift track circuit system is widely used in high-speed railway. Affected by maintenance quality, external environment, equipment characteristics and other factors, it is inevitable that the "red light band" fault occurs in the section track circuit. The "red light band" fault of track circuit has great interference to the normal transportation order of the train, and the factors causing the "red light band" fault are complex, so it is difficult to deal with the fault emergently. Combined with the mesh loop method, this paper analyzes and discusses this problem by making full use of centralized signal monitoring and observation, and puts forward the emergency disposal analysis method, which can provide reference for similar projects.
