염해지역에서의 철도 전차선로설비 절연성능과 습도와의 영향 분석

초록

In this paper, the effects of humidity and insulation performance were analyzed for the catenary facilities installed on the railway affected by salt sea. For this purpose, a condition determination test was performed on the power supply cables and support insulators. The test results show that the insulation performance is affected by humidity in the case of power supply cables and support insulators which can be determined as an early stage of deterioration of the facility. Therefore, it is seemed necessary to establish periodic monitoring and replacement plans.
