Abstract

The role of the turnouts installed on the points of railway branches and intersections is to safely switch the directions of trains. In case of abnormal forces applied to the turnouts due to extreme operating conditions, it is difficult in the current system to conduct accurate diagnosis and measuring. Moreover, the existing measurement devices for turnout switching power are mostly based on foreign technologies, which provide only limited information on the switching power; this information is insufficient for effective monitoring and maintenance. In this paper, through an analysis of the characteristics of the switching and locking function, the problems in turnout power measurements of current electrical point machines in Korea are examined. And based on the results, a new sensor-based method for measuring switching power is proposed.

분기기는 선로가 분기되거나 또는 교차하는 지점에 설치되어 열차의 이동 방향을 안전하게 변경하는 역할을 한다. 그러나, 운영 환경에 따라 비정상적인 힘이 분기기에 발생할 경우, 정확한 진단 및 검측을 실시할 수 없는 단점이 있다. 또한 분기기의 전환력을 측정하는 대부분의 장치는 국외 수입에 의존하며, 단순히 전환력 측정값으로 데이터가 한정됨으로서 분기기와 전기선로전환기간의 이상 상태, 운영 및 유지보수를 위한 데이터 등에 활용하기에 불충분한 것으로 조사되었다. 본 논문은 국내에서 사용중인 전기선로전환기의 전환기능과 쇄정기능의 특성 분석을 통해 기존에 사용된 분기기 전환력 측정의 문제점을 제시한 후, 이를 해결하기 위한 센서 활용 분기기 전환력 측정 방법을 제시한다.
