초록

동작 특성에 따라 궤도회로 장치는 신호기 장치, 선로전환기 및 기타 안전과 관련된 장치의 직접 또는 간접 제어를 위해 설치되며, 주로 열차의 검지, 지상에서 차상으로 제어정보 전송, 궤도 깨짐 검지 및 귀선 전류 전송에 사용된다. 특히 귀선 전류는 신호시스템, 전력시스템 및 전차선 및 궤도회로장치와 관련이 있다. 신호시스템에서 가장 중요한 구성 요소 중 하나인 귀선 전류는 선로변 유지보수자의 안전 및 전철화에 따른 철도 관련 전기시스템의 보호를 위해 적합하게 처리되어야 한다. 따라서, 과전류 상태로 인한 귀선 전류 불평형과 시스템 유도 장애 및 고장을 방지하기 위해서는 귀선 전류의 정확한 분석이 필요하다. 또한, 귀선전류 고조파에 의해 오동작이 발생하면 열차 운행 중단 등의 문제가 발생될 수 있다. 본 논문에서는 이러한 귀선 전류 측정 및 분석 방법을 제시하고 고속열차 운행에 따른 호남고속철도 노선에서의 귀선전류 고조파 시험 결과를 제시하고 있다.

Depending on the operating characteristics, track circuit is installed for the purpose of direct or indirect control of the signal device, point switch machine and other security device. These are mainly used for train detection, transmission of information, broken rail detection and transmission of return current. Especially, the return current is related to signal system, power system and catenary line, and track circuit systems. It is one of the most important component shall be dealt for the safety of track side staff and for the protection of railway-related electrical system according to electrification. Therefore, an accurate analysis of the return current is needed to prevent the return current unbalance and the system induced disorder and failure due to an over current condition. Also, if the malfunction occurred by the return current harmonics, it can cause problems including train operation interruption. In this paper, we presented measurement and analysis method at return current and it's harmonics by high speed train operation on the honam high speed line.
