PURPOSE:To improve the operating efficiency of an electric feeder facility in the feeding system of an electric railway by applying a feeding method that the feeding facility of one system feeds current to three or more feeder sections and each of them is fed with the current by three or more feeder substations each of which has breakers on the secondary side. CONSTITUTION:Substations 11 to 14 include primary breakers 11J to 14J and 11Ja to 14Ja between high potential wires 2 and 2a from receiving substations, performing selection and breaking of a receiving system. Breakers 11L to 14L and 11M to 14M are integrated in feeder facilities 11K to 14K on the secondary side, respectively and connected to divided feeder wires 20U to 24U and 21D to 25D. Each of the divided feeder wires 20U to 24U and 21D to 25D is associated with either one of feeder substations 11 to 14 for any one of up and down train feeder sections 40. Flows of feeder current are as shown by an arrow of the solid line in normal service, while shown by an arrow of the broken line under an abnormal load. When all the substations are operated, loads are applied in proportion to lengths of applicable sections, improving the operating efficiency. |
