电化区段高压脉冲轨道电路干扰机车信号分析

Analysis of High-voltage Pulse Track Circuits Interfering with Locomotive Signals in Electrifi ed Sections

高压脉冲轨道电路是解决轨道电路分路不良问题的新型轨道电路制式之一,在一些站场应用后改善部分因轨面锈蚀而导致的分路不良状况,但在实际应用中却存在干扰机车信号的问题。结合现场实际发生的案例,分析电气化区段中应用的高压脉冲轨道电路对机车信号造成干扰隐患问题的成因与机理,提出针对性改进建议。

High-voltage pulse track circuit is one of the new track circuit systems to solve the problem of poor shunting of track circuits.After being applied in some stations,the poor shunting caused by rail surface corrosion has been improved,but in practical application,there is the problem of interference with locomotive signals.Based on the actual cases,this paper analyzes the causes and mechanism of the potential problem caused by the high-voltage pulse track circuits applied in the electrifi ed sections,and puts forward some targeted improvements.
