ZPW-2000轨道电路继电器可靠性研究分析

Research and Analysis of Reliability of ZPW-2000 Track Circuit Relay

对ZPW-2000轨道电路之基础器材继电器可靠性进行研究分析,重点对继电器的核心部件——继电器触头的微观状态进行深入研究。触头作为铁路继电器接触系统的主要执行部分,其表面的形貌与污染物成分对于接触性能的变化有着至关重要的影响。

The paper studies and analyes the reliability of relay that is the basic equipment of ZPW-2000 track circuit,focusing on the micro state of relay contact,the core part of relay.As the main executive part of the contact system of railway relay,the surface morphology and pollutant composition of the contact have a vital infl uence on the change of contact performance.
