초록

Current of DC traction systems flows from the positive busbar of the substation, through the overhead contact system, to the vehicle, and returns through the running rails. Because the rails are not very effectively insulated from the earth a certain amount of current flows into the earth, especially in the area near the load and depots. At the place where the stray current leaves the rail and pipe, corrosion may take place. In this paper we introduce the electrolytic corrosion protection methods of depots using silicon rectifier for the rail.
