The present invention can solve high-speed maglev train effectively after the et out of order temporary term stop, and the electricity consumption of electrical equipment comes source problem on the car, has filled up the blank in this field.For the maglev train system that carries out commercial operation, keep power supply under can nonserviceabling voluntarily to electrical equipment on the car, with the adaptability to changes that improves greatly in the magnetic suspension train operation process fault, satisfy the requirement of passenger, provide more for the large-scale commercial applications operation of the such new traffic tool of magnetic suspension train drops into that failure-free guarantees ride comfort.
Description of drawings:
Above-mentioned purpose of the present invention and feature will become clearer in the following description to preferred embodiment in conjunction with the accompanying drawings:
Fig. 1 is that vehicle-mounted suspending chopper is to the electrically-charged schematic circuit diagram of Vehicular accumulator cell.
The specific embodiment:
The present invention utilizes the characteristics of vehicle-mounted levitating electromagnet number of turns of winding much larger than the onboard line generator windings number of turn, under the condition of the line frequency that does not exceed the train stop section, power supply voltage range, charger when the vehicle-mounted suspending chopper of suspension system is used as the Vehicular accumulator cell charging has solved the problem of carrying out emergent charging to Vehicular accumulator cell.
When high-speed maglev train breaks down in operational process, at first detect and determine vehicle-mounted levitating electromagnet coil position by vehicle location, determine and to produce impulsive magnetic field at which phase winding axis place of electrical motor according to the position relation of the linear synchronous motor winding on itself and the track, so that the axis of impulsive magnetic field is over against the magnetic pole of vehicle-mounted levitating electromagnet.Connect with this phase winding after other two phase windings parallel connections with electrical motor.Linear synchronous motor winding on track passes to the single phase alternating current of certain frequency, in air gap, set up impulsive magnetic field, make the magnetic flow of vehicle-mounted levitating electromagnet coil institute interlinkage in time alternation take place and produce induced potential, when the frequency of single phase alternating current power supply makes the induced potential of vehicle-mounted levitating electromagnet coil be higher than the charging valtage of Vehicular accumulator cell, vehicle-mounted levitating electromagnet coil promptly can charge to Vehicular accumulator cell by the vehicle-mounted suspending chopper that plays valve action, to keep the electricity consumption of electrical equipment on the car.
