Zusammenfassung:	PURPOSE:To obtain a fail safe power supplying system by connecting a branch line through a resistor between insulated and divided trolley wires and a trolley wire which forms a current feedback line, and delivering a control signal when the current of the branch line falls within the prescribed range. CONSTITUTION:A power supply line TL0 is connected with trolley wires T1-T3 insulated and divided corresponding to closed zone lengths through branch lines TB2, TB3. The line TL0 is not insulated nor divided. Resistors r1, r2 are connected between the lines T1-T3 and the line T0. Train detectors TD1, TD2 judge the level of a branch current (i) to control ON or OFF switches S1, S2, and control conveyor unit group in the corresponding zone. At this time, if the current (i) is out of the prescribed range, it is judged as being trouble to OFF-control the switches S1, S2.
