고속선과 기존선 인터페이스 구간의 동조유니트 BA 분석 = Analysis on Turning unit BA on the interface section between High speed line and Conventional line

다국어 초록 (Multilingual Abstract)

In Gyeongbu high speed line, information transmission from wayside to rolling stocks are carried out via UM71 AF track circuits. And with the use of various frequencies, JES(Electrical Separation Joint) are used to conduct interference and blocking for adjacent track circuits. For such a non-insulated track circuit failures mainly occur in trackside, especially failures which are impossible to identify causes often occur. In this paper we analyze on turning unit BA of track circuits on which the failures occurred. For a relevant review, with the use of design values and measured values in the failure sites, we apply the maintenance method which SNCF has used
