PURPOSE:To securely carry out power running and regenerating by providing two feeder lines between feeder lines for adjacent substations through three sections and connecting a diode and a thyristor and a Zener diode to each of both side sections respectively. CONSTITUTION:Feeder lines 3, 4 are provided between feeder lines 2, 5 for adjacent substations 1a, 1b through sections 6a-6c, and diodes 7a, 7b thyristors 11a, 11b for a regenerating currnet, and Zener diodes 12a, 12b are connected both between feeder lines 2, 3 and between feeder lines 4, 5 respectively. Thereby, in whichever position among the feeder lines 2-5 and sections 6a-6c an electric car 8 may be positioned, a power-running power can be securely supplied while a regenerating power can be efficiently regenerated. Also, the reliability of the device can be increased by means of a simple circuit consisting of thyristors, Zener diodes, etc. |
