Description
Technical field
The present invention relates to the traction technique in a kind of urban railway magnetic suspension traffic technique field, be specifically related to a kind of output device that is installed in the traction convertor on the urban railway magnetic suspension train.
Background technology
The urban railway magnetic suspension train is a type of the floating train of normal magnetic conduction, and the principle of its suspension is to utilize the electromagnet that the is installed in lower vehicle attraction to the F shape magnetic conduction rail that is installed in the track down either side, and train is suspended.Adopt vehicle-mounted current transformer to supply with traction electric machine frequency conversion voltage, the operation of short preliminary linear Induction Motor-Driven magnetic-levitation train.The urban railway magnetic suspension train has advantages such as climbing capacity is strong, radius of turn is little, the operation noise is low, energy consumption is lower, cost is reasonable, is a kind of novel rail pattern that has very much development potentiality.
In the present track traffic trailer system, generally adopt current transformer directly to drive the mode of traction electric machine tractor-trailer train.The mode of traction that is adopted on the urban railway magnetic suspension train also is this mode, as shown in Figure 1.Vehicle-mounted current transformer comprises switch cubicle, and with the inversion module that the circuit of output terminal of this switch cubicle is connected, the circuit of output terminal of this inversion module connects motor.Vehicle-mounted current transformer is obtained direct current from dc bus, is directly to output to traction electric machine behind the alternating current by the inversion module of a three-phase with dc inverter, and train is implemented traction.The traction electric machine that is connected to inversion module output can be 1 or multiple electric motors.During multiple electric motors, can be in parallel, also can be series connection, or series connection earlier is in parallel again or first parallel connection is connected again.
