The output voltage of first inverter 103 and third inverter 105, the second inverter 104 and the 4th inverter 106 with
The speed of service of vehicle is directly proportional, reaches as high as 10kv.Therefore this requires entire transmission systems will be according to highest electricity
Grade is pressed to carry out insulating protection, the insulating protection type selecting of components selection and line wires.
When maglev vehicle 123 is run on the line, since power supply system is only that the linear motor long stator being presently in supplies
Electricity, i.e., current control switch need to be closed, the switch circuit breaking of other sections；When vehicle drives into next linear motor long stator section
When, the long stator section of a upper linear motor will be switched off.If current magnetic-levitation train is in section 1, then route controls first line
Control switch 111 and the second route control switch 112 closure, All other routes control switch 113 to 116 are in off-state.
When maglev vehicle 123 moves on, i.e., will drive into section 2, tertiary circuit control switch 113, the 4th line at this time
Way control switch 114 is closed, and line switching 115 and 116 is still in off-state.

Phase when maglev vehicle enters section 2 by section 1 will be repeated when maglev vehicle 123 enters section 3 from section 2
The line switching answered disconnects and closed action.
From the above, it is seen that switch switches over extremely important within the system, if there is failure, vehicle will lead to
It is unable to run.It is also very high to the reliability requirement of line switching.During Project Realization, it is unfavorable for parts selection.
And in the present invention, it is explained with two sections, as shown in Figure of description 2, power supply system includes:
The first DC/AC inverter 1, the 2nd DC/AC inverter 2, the 3rd DC/AC inverter 3, the 4th DC/ positioned at section 1

It further include simultaneously the maglev vehicle 15 run on route, the first data telecommunication line 13, the second data telecommunication line 14；
Wherein: the linear motor long stator in specification be in claims unit section stator (it is hereafter similar, no
It repeats again).Above-mentioned data telecommunication line is for transmitting signal system to the traction braking instruction of each DC/AC inverter, vehicle
Phase signal, to control frequency, phase and the electric current of the output of the DC/AC inverter on entire route；Enable each inverter
Same-phase power supply is carried out, when maglev vehicle being avoided to cross section, the phase in two sections is inconsistent to endanger transregional, vehicle operation.Together
When also transfer destination speed command to control running velocity.
And it is well known that the motor for maglev vehicle is linear motor.Belong to according to structure type flat.Flat
Linear motor is divided into long primary (stator) and short primary (stator) two class, and the left motor long stator in the present invention and right side are electric
Captain's stator is long stator.
First DC/AC inverter 1, the 2nd DC/AC inverter 2, the 3rd DC/AC inverter 3, the 4th DC/AC inverter 4,
The input of 5th DC/AC inverter 16, the 6th DC/AC inverter 17, the 7th DC/AC inverter 18, the 8th DC/AC inverter 19
It is connected with DC3000V, and DC3000V is the common and mature power supply unit of urban track traffic.And voltage was well below both
There is in power supply system the drawbacks of by three-phase 10kV high voltage AC transmission, can lower for high-voltage protection and components selection
And the cost of cable.

Left four unit section stators 26, the catenation principle of right four unit section stators 27 are consistent with the connection method of the first from left unit section stator 9.
In the present invention, when unit section stator is specially two groups, the length of any one unit section stator is magnetic suspension column
The half of the length of vehicle.That is, when a train is made of four section compartments, as shown in Figure of description 2, the second from left unit section stator
11, the length of the first from left unit section stator 9, a right unit section stator 10 and right two unit section stators 12 should all be not more than magnetic-levitation train
The length of half；Exclusive or, when a train is made of four section compartments, the length of flat stator section is the length in two section compartments, this
Advantageously reduce induced electromotive force.As another example, when a train is made of six section compartments, the second from left unit section stator 11, the first from left
The length of unit section stator 9, a right unit section stator 10 and right two unit section stators 12 should all be no more than magnetic-levitation train half
Length；Exclusive or, when a train is made of six section compartments, the length of flat stator section is the length in three section compartments.
The length set-up mode of above-mentioned unit section stator can refer to transformer principle；Specifically, we can be list
Position section stator regards the primary side of transformer as, and vehicle upper rotor part part regards secondary side as.The voltage on secondary side and the voltage of primary side are directly proportional.
If the length of unit section stator is 50 meters, then the length in a section compartment is 25 meters.If stator voltage is 1000V, incuding
Afterwards, the voltage on vehicle is just 500V.If it is not done, the voltage on vehicle will be very high, it is unfavorable for insulating protection.
The unit section stator in each section and adjacent unit section stator do not constitute physical connection, this can be same route
On, multiple magnetic-levitation trains run create conditions simultaneously.Such as when there is a column magnetic-levitation train to operate in section 1, magnetic is floating at this time is arranged
The power supply of vehicle is powered by DC/AC inverter 1-4, if another train is run in section 2, is powered by DC/AC inversion
Device 16-19 power supply.Since the current speed of each train is different, speed is controlled by frequency, electric current of unit section stator etc..Than
Such as in existing power supply system Fig. 1, since entire route or multiple sections are then passed through by same set of inverter power supply
It powers after switch control to unit section stator, just determines that the power supply section can only exactly allow single-row train operation.Certainly exist
Before the train in section 1 is driven out to section 1 and will enter section 2, the train positioned at section 2 must be driven out to section 2.
Whole DC/AC inverters are used to respectively drive the unit section stator after series connection, and the length of whole service cables
Spend identical, and the length of service cable should be short as far as possible；First DC/AC inverter 1, the 2nd DC/AC inverter 2, the 3rd DC/AC are inverse
Become device 3, the 4th DC/AC inverter 4 and the second from left unit section stator 11, the first from left unit section stator 9, a right unit section stator 10, the right side
The distance between two unit section stators 12 will be as short as possible, on the one hand can shorten the length of service cable 5-8, reduce high voltage
Protection cost and line wires cost.On the other hand inverter 1-4 and unit section stator 9-12 should be formed modular set
Meter is promoted convenient for engineering.
In addition to this, the total length of the left and right sides whole unit section stator in the same power supply section can be set to
Together.Such setting is advantageously implemented above-mentioned technical effect, and multiple row magnetic suspension train may be implemented and travel in different sections respectively,
Improve operation density；Wherein, that does not answer doctrine equally thinks numerically essentially equal, but should combine above-mentioned technical effect two
The length of person is in certain range, namely generally equivalent.
Exclusive data communication line 13-14 is mainly used to transmit the data information between the inverter that is connected in certain condition.Than
As exclusive data communication line 13 is used to transmit phase, electric current and the frequency between DC/AC inverter 1-2 and DC/AC inverter 16-17
The relevant informations such as rate.

The common and mature power supply unit of urban track traffic.And voltage is well below the height transmitted in existing power supply system by exchange
Drawback is pressed, the cost for high-voltage protection and components selection and cable can be lowered.
The output end of DC/AC inverter 01-03 and DC/AC inverter 04-06 passes through service cable 07-09 and unit respectively
Duan Dingzi 010-012 is connected.Relative to existing power supply system, switch of just removing controls.On the one hand the form can be reduced into
This, while also eliminating control switch there are brought hidden danger.
When DC/AC inverter 01-06 and DC/AC inverter any one failure of 021-016, the list in the section 1/6 is influenced
Position section stator power supply, but vehicle operation is not influenced.Embodiment compared to Fig. 2, single fault of converter draw idea to route
The power supply of long stator is smaller.
