A power supply device is provided to minimize the error occurrence of transportation system since the power supply is maintained stably in the turn-table section. A power supply device comprises as follows. The single-phase power line(R1,S1,T1) is set up in the first turn-table section(200) and the second turn-table section(400). The sliding contact point(P111,P112) connected to the transportation system is additionally set up with the single-phase power line. In the first and the second turn-table section, the supply of the single-phase power to the transportation system(500) is maintained through the connection of the sliding contact point.
