The chain has a pantograph (4) for collecting electric energy on a feeder i.e. catenary system (2). Traction casings (18) have three-phase static traction converters (38) for supplying the electric energy to electric motors (6), respectively. Static circuit breakers (201-203) are arranged between the pantograph and the traction casings, respectively. The circuit breakers are controlled for being opened, when the current traversing the respective circuit breakers attains a predetermined threshold. |
