열화상 카메라를 이용한 도시철도 몰드변압기 상태모니터링 방안 도출

초록

Due to the fact that many urban railway electric facilities have almost reached their lifetime limit, there is a need to develop a system that monitors and diagnoses condition of electric facilities in real-time. In this paper, we have introduce a infrared thermograph monitoring system that monitors condition of mold transformers on urban railway. This system could be applied to determine replacement intervals and prevent hazardous accidents. Introduced in this paper is a condition monitoring system implemented by an IR-camera that checks partial discharge of a mold transformer at an urban railway substation. The above system is completely contact-less and can be applied to monitor overall deterioration of urban railway electric power facilities.
