Abstract

분기기의 동작은 전기선로전환기에 의해 공급되는 전환력을 기반으로 하며, 안전한 전환을 위해서는 적절한 전환력과 전환시간을 유지해야 한다. 분기기의 전환이 완료되면 안전한 열차 운행을 위해 분기기의 밀착 및 쇄정 동작을 실현하며, 이는 밀착검지기 또는 쇄정장치를 통해 상시 감시된다. 그러나, 분기기의 노화, 분기기 설치 상태, 및 분기기 기본 레일과 텅레일간의 이물질 침입 등은 전기선로전환기의 비정상 동작을 유발하며, 이는 최종적으로 전환전류와 전환시간에 영향을 인가한다. 본 논문은 전기선로전환기의 전환전류와 전환시간을 활용하여 분기기의 상태 진단 및 감시 방안에 대해 검토하였다. 관련 검토 결과는 기존선에 설치된 NS-AM 전기선로전환기를 사례로 분석하였다.

电点机开关电流和开关时间分析用于道岔状态诊断和监测

分机的动作以电力线路转换器提供的转换力为基础，为了安全转换要保持适当的转换力和转换时间。分机转换结束后，为了列车的安全运行，将实现分机的贴合及锁定动作，并通过贴合检测器或锁定装置进行随时监视。但是，分歧器的老化、分歧器设置状态、以及分歧器基本导轨和空轨之间异物侵入等会导致线路转轨的非正常动作，最终会影响转轨电流和转换时间。本论文利用电线路转换器的转换电流和转换时间，对分歧器的状态诊断及监视方案进行了研究。相关研究结果以设置在现有线路上的NS-AM线路转换器为例进行了分析。

期刊介绍： The Journal of the Korean Society for Railway (JKSR) launched in 1997 aims to provide a platform to exchange research information, establish and pioneer railway-related academia, and present research results that are both practical and unique. The journal covers various research results, derived from theory and experiments, on topics related to railways such as railway policy and management, railway facilities, carriage machinery, electrical signals, and track engineering. It includes research outcomes that can contribute directly to the improvement of railway technologies as well as innovative studies on fundamental areas that can be applied to railways including mechanics, electricity, civil engineering, logistics, management and so on. The themes addressed by the journal include, but not limited to the following: Rolling stock & Mechanical systems (materials, fracture, non-destructive testing, mechanics of materials and structures, design, dynamics and control, noise and vibration, heat and fluid mechanics, energy and power engineering, system engineering, reliability, maintenance, safety, etc.), Power & Signal systems (power engineering and systems, electrical devices, circuits and systems, materials and devices, control and measurement, automation, signal processing, electrical and information communication, reliability, maintenance, safety, etc.), Civil engineering for railway (structural engineering, material engineering, dynamics, seismic engineering, geotechnical engineering, measurement, geodetic survey, mapping, GIS, construction, architectural and environmental engineering, transportation engineering, etc.), Transportation policy & Operation (railway traffic planning and engineering, railway management policy, railway technology policy, railway logistics, railway operation, railway information system, railway culture, etc.).
