선로변 신호장치 단열 코팅 적용에 따른 신뢰성 향상 연구

초록

Recently global climate change yields trend on increasing average temperature and diurnal range. It results in frequent malfunctions due to the increase of internal temperature of the steel enclosures including ATP LEUs. Accordingly the application of insulation of the enclosures is required in the Railway construction and undertaking. In this paper, it introduced to UTHI(ultra-thin heat insulation paint), which was applied on the lineside electronic equipment(LEU), to verify the effect of improvement of reliability. In the future, we expect the economic and practical insulation shall be applied to improve the efficiency of the operating field.
