3/30/2023 0 Comments Locomotive rail routeThe motor circuit as each section of resistance is cut out in steps. It is controlled byĬommands from the driver's cab and regulated by the fall of current in The camshaft is driven by an electric motor or pneumaticĬylinder. The cams on the shaft are arranged to ensure that theĬontactors open and close in the correct sequence. Often a source of spurious circuit breaker tripsĭC electric traction power circuits use a camshaft to open or close theĬontactors controlling the resistances of the traction motor powerĬircuit. If low oil pressure is detected, the relay trips The battery is usually connected across the DC controlĭevice inserted in the oil cooling circuits of electric locomotive Supplying essential circuits, such as emergency lighting, when the line Trains are provided with a battery to provide start up current and for Balancing SpeedĮconomical service speed at which the tractive effort of the trainĮquals the train resistance and no further acceleration takes place. CurrentĬollected from the overhead line or third rail is returned via the axleīrush and one of the running rails. Substation once power has been drawn on the locomotive. Means by which the power supply circuit is completed with the It can be used on DC and AC electrified railways with suitable control electronics and on diesel-electric locomotives.
