Description
Technical field
The present invention relates to energy-saving electric vehicle, particularly relate to a kind of electric locomotive power supply system.
Background technology
Day by day increase severely now at environmental protection consciousness; battery-driven car replaces the trend of conventional gasoline diesel-powered vehicle irreversible; but with regard to current occurred novel electric vehicle; the electricity that it is laid in is limited is very fatal shortcoming; cause vehicle period of service end; charging duration is long, and inconvenient.Storage battery in addition for battery-driven car is very expensive again, but reserve of electricity is few, and the life-span is short, and environmental pollution is serious, extremely impracticable.
Summary of the invention
The object of the present invention is to provide a kind of electric locomotive power supply system, the electricity solving accumulators store on existing battery-driven car is limited, and period of service is short, length consuming time of charging and charging is inconvenient, and the problem that use cost is high.
For solving the problem, the technical solution used in the present invention is:
A kind of electric locomotive power supply system, comprise master controller, battery pack and electrical motor, described master controller is arranged on the feed circuit that battery pack is powering electric motors, described electrical motor provides power for locomotive, also comprise impeller type turbine, light-duty low-speed generator, high-pressure hydraulic pump and reserve tank, described impeller type turbine is connected with light-duty low-speed generator by turning cylinder, described light-duty low-speed generator is connected to battery pack by charging circuit, described reserve tank is connected with impeller type turbine by high-pressure hydraulic pump, described high-pressure hydraulic pump and the electrical connection of described master controller.
Further technical scheme is, described battery pack and electrical motor are arranged in the engine bin of locomotive, described master controller is arranged in the operator's compartment of locomotive, and described impeller type turbine, light-duty low-speed generator and water storage are mounted in bottom the latter half of locomotive.
The beneficial effect adopting technique scheme to produce is: the electric power that this electric locomotive power supply system produces when generator operation is transported in electric energy storage device through main line, a power supply part in electric energy storage device is used for electrical motor and drives locomotive to advance, another part is used for the generating of high-pressure hydraulic pump drive electrical generators, due to the continuous work of water pump, follow-up constantly have power delivery in electric energy storage device, thus the continuous working of locomotive energy, ensure that the flying power of electric locomotive, avoid the period of service brought because accumulator electric-quantity is little short, the shortcoming of length consuming time of charging and charging inconvenience.
