Abstract: Firstly, focusing on the ZPW-2000 series track circuit system, this paper analyzes the requirements and principles of its lightning protection equipment and measures to explain the overall lightning protection logic of the system. Secondly, targeting at the lightning stroke failure problem of track circuits, it proposes the contents and methods for the determination of lightning introduction source and the criteria of failure types, which can effectively distinguish between direct lightning and induced lightning, and between trackside lightning stroke failure and ground counterattack failure. Finally, this paper also provides an in-depth analysis of the failure points, which has great significance for failure analysis and troubleshooting.

Key words: track circuit, lightning protection, trackside lightning stroke failure, ground counterattack failure, failure criteria

摘要: 基于ZPW-2000系列轨道电路系统,通过分析其雷电防护设备和雷电防护措施的要求和原理,阐述系统整体雷电防护的逻辑。针对轨道电路的雷击故障问题,提出对雷电引入源的判断、故障类型的判据等内容和方法,可以有效区分直击雷和感应雷、轨旁雷击故障和地反击故障类型。最后对故障点进行深入分析,对于故障分析和故障点排查整改具有重要意义。
