Abstract

Abstract: This paper introduces the common faults of the arranged contacts of switch machine, and analyzes the causes of the common faults. The cleaning and maintenance device for moving contact ring is designed and verified by experiments. The results show that the installation of moving contact ring cleaning and maintenance device can effectively reduce the resistance of contact and the contact conversion resistance. The research can effectively reduce the risk of blocking and breaking of arranged contacts of switch machine, and provide a new solution to ensure the reliability of switch machine.

Key words: maintenance device, switch machine, arrangement type, contact

摘要： 介绍铁路道岔转辙机排布式接点常见故障并对常见故障发生的原因进行分析。通过研究设计针对动接点环的清洁维护装置并进行实验验证，结果表明，安装接点维护装置能够有效降低接点的接触电阻值，并一定程度地减少接点转换阻力。该研究能有效降低转辙机排布式接点卡阻和断表示故障风险，为保障转辙机工作的可靠性提升提供新的解决方案。
