초록

In this paper, we propose a catenary heating measurement system using small-scaled DC power supply for the configuration of a DC de-icing system and measure the current distribution ratio and heating value of contact wire and messenger wire. As a result, the measurement showed similar temperature increases in comparison with theoretical formulas, and it is believed that relatively accurate predictions will be possible for future melting temperature estimations through theoretical formulas.
