    摘要: A method and system is provided for detecting and performing diagnostics regarding an incipient ground fault that may occur in an electrical propulsion system of a traction vehicle, such as a locomotive, transit vehicle, or off-highway vehicle. The method allows providing a first ground connection for the electrical propulsion system. This first ground connection forms a grounding path generally used by the electrical propulsion system during normal operation. The method further allows providing a second ground connection for the electrical propulsion system. This second ground connection forms a grounding path selectively usable in lieu of the first ground connection. A control strategy is defined for switching between the first ground connection and the second ground connection. A respective leakage current associated with at least one of the first and second ground connections may be monitored. Switching between the first and second ground connections may be controlled based on the monitored leakage current associated with at least one of the first and second ground connections.

    摘要: A system and method for modification of a baseline ballast arrangement of a locomotive having an overall tractive effort rating based on symmetrical distribution of weight and driving torque applied by the locomotive to the respective axles of the locomotive. The system includes a locomotive truck comprising an un-powered first axle and a powered second axle. The system also includes a first suspension assembly configured to apply to the first axle a first portion of a locomotive weight and a second suspension assembly configured to apply to the second axle a second portion of the locomotive weight different from the first portion. An amount of locomotive weight allocated from the first axle to the second axle allows modification of a baseline ballast arrangement by reducing an amount of ballast in the baseline ballast arrangement corresponding to the amount of weight allocated from the first axle to the second axle.

    摘要: A shoot-through protection system for an electric power generating system including a synchronous generator, a bridge rectifier coupled to an output of the generator for converting alternating current (AC) from the generator to direct current (DC) at a rectifier output, and at least one inverter coupled to the rectifier output for converting the DC output to a controlled frequency AC output for application to a load. The generator has a separately excited field winding in which the magnitude of field excitation controls the voltage output of the generator. A microprocessor-based controller regulates generator field excitation in a manner to control the DC output of the rectifier. The generator is protected from a shoot-through in the inverter by detecting a sustained voltage drop in the rectifier DC output and reversing generator field excitation in response to such a voltage drop to rapidly drive generator output voltage to substantially zero volts.

    摘要: A system is provided for use with, a wheeled vehicle. The system includes a media reservoir capable of holding a tractive material that includes particulates; a nozzle in fluid communication with the media reservoir; and a media valve in fluid communication with the media reservoir and the nozzle. The media valve is controllable between a first state in which the tractive material flows through the media valve and to the nozzle, and a second state in which the tractive material is prevented from flowing to the nozzle. In the first state, the nozzle receives the tractive material from the media reservoir and directs the tractive material to a contact surface such that the tractive material impacts the contact surface that is spaced from a wheel/surface interface. The system can modify the adhesion or the traction capability of the contact surface with regard to a subsequently contacting wheel.

    摘要: A system and method for modification of a baseline ballast arrangement of a locomotive (or other rail vehicle) having an overall tractive effort rating based on symmetrical distribution of weight and driving torque applied by the locomotive to the respective axles of the locomotive. The system includes a locomotive (or other rail vehicle) truck comprising an un-powered first axle and a powered second axle. The system also includes a first suspension assembly configured to apply to the first axle a first portion of a locomotive weight and a second suspension assembly configured to apply to the second axle a second portion of the locomotive weight different from the first portion. An amount of locomotive weight allocated from the first axle to the second axle allows modification of a baseline ballast arrangement by reducing an amount of ballast in the baseline ballast arrangement corresponding to the amount of weight allocated from the first axle to the second axle. The axle weight distribution involves relatively slight weight distribution compared to the nominal weights normally carried by the axles.
