Abstract

Abstract: The turnout switching resistance is the most direct indicator of the turnout working state. It is also an important test item for railway integrated commissioning and testing, and an important item for the on-site operation and maintenance of turnout switching equipment. The turnout switching resistance shall meet the indicator requirements, and an increase in the turnout switching resistance will increase the load of the switch machine and lead to motor idling and turnout switching failure in serious cases. This paper introduces the meaning and composition of the turnout switching resistance, discusses the online monitoring technology for the turnout switching resistance, and proposes solutions to practical problems, which has positive significance for the development of intelligent operation and maintenance of the turnout switching system.

Key words: railway turnout, switching resistance, online monitoring technology

摘要： 道岔转换阻力是道岔工作状态最直接的反映，是铁路联调联试的重要测试项点，是道岔转换设备现场运维关键项。道岔转换阻力应符合指标要求，转换阻力变大会加重转辙机负载，严重时会导致电机空转，造成道岔转换故障。介绍道岔转换阻力含义和组成，对道岔转换阻力在线监测技术进行探讨，针对现实问题提出解决方案，对道岔转换系统运维向智能化方向发展具有积极意义。
