[전기철도] 노후 활차식 자동장력조정장치 정밀분해 진단분석 연구

다국어 초록 (Multilingual Abstract)

The contact wire used in the electric railways is expanded and contracted according to the as a function of temperature, and the tension on the contact wire would be changed due to the elastic expansion caused by aging and abrasion. In the case of outdoor temperature rising, the contact wire would be expanded, and the tension on the wire decreased, then sagging of the contact wire could be occurred. When the pantographs of the rolling stock come through the section of contact wire sagged, the contact wire could be broken consequently because of the incomplete contact and arc caused by vibration of the overhead, and expedited abrasion on the contact wire and pantograph. On the other way, the outdoor temperature dropping, the tension on the contact wire would be increased and the wire lifted up. Then it harms the equilibrium of the contact wire, and constant electricity collection of the pantograph. In this study a diagnostic analysis with precise decomposition for the decrepit wheel type automatic tensioning device(2 ton) accorded with the KRS-PW 0010-18(R) was carried out and tried to figure out the operation status of the device, and to identify the possibility of life time extension and the aging changes, so that the maintenance policy optimized for the tensioning device would be suggested through this study.
