PURPOSE:To provide a 3-phase power supply apparatus which minimizes the space for installing the electric car line and eliminates mutual contact of collectors against normal oscillations of vehicles while facilitating return of collectors whenever they are off the electric car line due to abnormal oscillations. CONSTITUTION:The guided trolley is so arranged that a vehicle having a travelling wheel 4 and a guided wheel 5 on a rail comprising a running course 1 and guiding rails on both sides thereof. Herein, three electric car lines 7 to 9 with which 3-phase AC power is fed are arranged above one guided rail 2 in such a manner that the central line is projected from the other ones leaving a space above and below the line. Collectors 11, 12 and 31 are arranged on the vehicle 3 corresponding to the respective lines 7 to 9. The collectors are respectively provided with collection shoes 12, 22 and 32 which contacts the corresponding line at such an angle as to form a contact surface to one cylidrical surface and insulated shoes 13, 23 and 33. |
