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.

The line switching answered disconnects and closed action.
It is upper as can be seen that state switch switch over it is extremely important within the system, if there is failure, will lead to vehicle without
Method operation.It is also very high to the reliability requirement of line switching.During Project Realization, it is unfavorable for parts selection.
The power supply system of magnetic suspension train provided by the invention, as shown in Figure of description 2, including first at the uniform velocity power it is inverse
Become device 1001 and second at the uniform velocity to power inverter 1003, deceleration/acceleration power supply inverter 1002 (namely subtracting in claim 1
Speed accelerates power supply inverter), service cable 1004-1007, at the uniform velocity section linear motor long stator 1008 and 1011, braking section straight line
Motor long stator 1009, accelerating sections linear motor long stator 1010, control switch 1012 and 1013 and magnetic-levitation train 1014；
First inverter 1001 and second of at the uniform velocity powering at the uniform velocity is powered inverter 1003, and deceleration/acceleration is powered inverter
1002 are connected with high voltage power supply (DC3000V)；On the whole using dispersion direct current supply.
When magnetic-levitation train 1014 drives at a constant speed from attached left side shown in Fig. 2, control switch 1012 is closed, slow down/
The power supply for accelerating power supply inverter 1002 to export is sent to the braking section straight-line electric of deceleration interval by deceleration service cable 1005
On captain's stator 1009.Supply frequency at this time, the parameters such as voltage and the power supply at the uniform velocity section linear motor long stator 1008 are special
Property is consistent.
After magnetic-levitation train 1014 enters deceleration interval, speed is constantly reduced, and train moves on, when vehicle front half
During entering station and acceleration area (station and acceleration area may be considered a section, and platform is located in the section)
When, the accelerating sections linear motor long stator 1010 of station and acceleration area is also not charged at this time, and train power supply relies on deceleration interval
Braking section linear motor long stator 1009 power.
When vehicle moves on, and vehicle half enters station and acceleration area, control switch 1012 is disconnected at this time, control
Switch 1013 is closed.Vehicle maximum power loss is up to half, while switching moment and can have instantaneous power loss, since vehicle is at this time
It enters the station, and is the process slowed down, therefore vehicle operation is not influenced.
When magnetic-levitation train 1014 stops in platform, passenger getting on/off, at this time since control switch 1012 disconnects, braking section is straight
Line motor long stator 1009 is not charged, and subsequent train is to cannot be introduced into station and acceleration area, therefore after fundamentally having prevented
Continuous train may enter by mistake through the possibility of platform.Wherein, the friendship at deceleration interval and station and acceleration area can be set in platform
Boundary position, but platform should be in station and acceleration area.
When magnetic-levitation train 1014 complete passenger getting on/off after, vehicle continue starting operation, when vehicle drive leave station and
After entering next at the uniform velocity section when acceleration area, i.e., vehicle is powered from by deceleration/acceleration power supply inverter 1002, is opened by control
1013 are closed by electrical energy transportation to station and the accelerating sections linear motor long stator 1010 of acceleration area, enters and is at the uniform velocity supplied by second
Electric inverter 1003 is powered, and is exported on electric energy at the uniform velocity section linear motor long stator 1011.
Control switch 113 disconnects at this time, and control switch 112 is closed, that is, allows for the possibility that next column pulls in.
By the above process, magnetic-levitation train 1014 completes primary out of the station.It, will be repeatedly above-mentioned when next train drives into
Step.
Figure of description 3 gives the structural schematic diagram that the another specific embodiment of power supply system is floated for magnetic.
Including the power supply of at the uniform velocity section inverter 100,200,300,400 and 3700,3800,3900,4000；Slow down/plus
Fast section power supply inverter 1300,1400,1500 and 1600.(corresponding portion only hereafter to simplify the explanation, is replaced with number
Part) it is necessary to be noted that each section four sections of traction electric machine long stators that have been picture, actual quantity should be much more
In four sections, when a traction electric machine long stator is 50 meters, if there is 2km long in a section, 40 stators should be shared
The alternate method connection under.Its detailed subgraph is shown in Fig. 5.
Inverter 100,200,300,400,1300,1400,1500 and 1600,3700,3800,3900,4000 input
Side is connected with DC3000V, and DC3000V is the common and mature power supply unit of urban track traffic.And voltage well below
The drawbacks of passing through three-phase 10kV high voltage AC transmission in existing power supply system can lower for high-voltage protection and component choosing
The cost of type and cable.
At the uniform velocity section power supply inverter 100 passes through service cable at the uniform velocity service cable 500 and linear motor long stator 1100
Connection, at the uniform velocity section power supply inverter 200 are connect by service cable at the uniform velocity service cable 600 with linear motor long stator 900,
At the uniform velocity section power supply inverter 300 is connect by service cable at the uniform velocity service cable 800 with linear motor long stator 1000, at the uniform velocity
Section power supply inverter 400 is connect by service cable at the uniform velocity service cable 700 with linear motor long stator 1200.
At the uniform velocity section power supply inverter 3700 passes through service cable at the uniform velocity service cable 4100 and linear motor long stator
4500 connections, at the uniform velocity section power supply inverter 3800 pass through service cable at the uniform velocity service cable 4200 and linear motor long stator
4600 connections, at the uniform velocity section power supply inverter 3900 pass through service cable at the uniform velocity service cable 4300 and linear motor long stator
4700 connections, at the uniform velocity section power supply inverter 4000 pass through service cable at the uniform velocity service cable 4400 and linear motor long stator
4800 connections.
Deceleration/acceleration power supply inverter 1300 is connected by cable 1800 and control switch K1-2 with K2-2, switch it is another
One end is connected with 2400 with 2600 respectively by service cable 2000 and 2200；Deceleration/acceleration power supply inverter 1400 passes through electricity
Cable 1700 is connected with control switch K1-1 with K2-1, the other end of switch by service cable 1900 and 2100 respectively with 2300 and
2500 are connected；Deceleration/acceleration power supply inverter 1500 is connected by cable 2800 with control switch K1-4 with K2-4, switch it is another
One end is connected with linear motor long stator 3400 and 3600 respectively by cable 3000 and 3200；Deceleration/acceleration power supply inverter
1600 are connected by cable 2700 with control switch K1-3 with K2-3, the other end of switch pass through cable 2900 and 3100 respectively with
Linear motor long stator 2300 is connected with 2500.
Relative to existing power supply system Fig. 1, just remove controls switch at the uniform velocity section.On the one hand cost can be reduced, together
When also eliminates control switch, and there are brought hidden danger.
The process steps that enter the station of magnetic-levitation train 5300 are as follows:
When magnetic-levitation train 5300 is run over from left side at the uniform velocity section 1 to be come, control switch K1 closure (includes K1-1, K1-
2, K1-3, K1-4), deceleration/acceleration power supply inverter output power supply is transmitted by service cable 1900,2100,2900,3100
To deceleration interval linear motor long stator 2300,2400 and 3300,3400.Supply frequency at this time, the parameters such as voltage with it is even
Power supply characteristic on the linear motor long stator 900,1000,1100 and 1200 in fast section 1 is consistent.
After magnetic-levitation train 5300 enters deceleration interval, speed is constantly reduced, and train moves on, when vehicle front half
Enter accelerating sections (containing station section) during when, at this time accelerating sections (containing station section) linear motor long stator 2500,2600
With 3500,3600 is also not charged, and train power supply is supplied by deceleration interval linear motor long stator 2300,2400 and 3300,3400
Electricity.
When vehicle moves on, and vehicle half enters accelerating sections (containing station section), control switch K1 is disconnected at this time, vehicle
Control switch K2 (including K2-1, K2-2, K2-3, K2-4) closure.Vehicle maximum power loss is up to half, while switching moment
There can be instantaneous power loss, since vehicle is the process for entering the station, and being deceleration at this time, therefore vehicle operation not influenced.
When magnetic-levitation train 5300 stops, passenger getting on/off in accelerating sections (containing station section), at this time since control switch K1 is disconnected
It opens, braking section linear motor long stator 2300,2400 and 3300,3400 is not charged, and subsequent train is to cannot be introduced into station section
, therefore fundamentally prevented subsequent train and may enter by mistake through the possibility in station section.This is also of the invention needs
The scope protected again.
After magnetic-levitation train 5300 completes passenger getting on/off, vehicle continues starting operation, when vehicle drive leaves accelerating sections
After entering next at the uniform velocity section when (containing station section), i.e., vehicle is from by slowing down and accelerating inverter 1300-1600 power supply of powering, warp
Control switch K2 is crossed by the linear motor long stator 2500,2600 and 3500,3600 of electrical energy transportation to accelerating sections (containing station section)
On, it enters by inverter 3700-4000 power supply of at the uniform velocity powering, output electric energy to uniform rectilinear's motor long stator 4300-4600
On.
When at this time, control switch K2 is disconnected, control switch K1 closure allows for the possibility that next column pulls in.
By the above process, magnetic-levitation train 5300 completes primary out of the station.It, will be repeatedly above-mentioned when next train drives into
Step.
Inverter 100,200,300,400,1300,1400,1500 and 1600,3700,3800,3900,4000 is any one
When a failure, the linear motor long stator power supply in the section 1/4 is influenced, but does not influence vehicle operation.
Linear motor stator electric 900 with next linear motor stator electric is separately connected by service cable, other areas
Between linear motor stator electric connection method it is consistent with 900 connection method of linear motor stator electric.Wherein, any one in attached drawing 3
Stator is unit section stator.
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 3, the second from left unit section stator
1100, the length of the first from left unit section stator 900, a right unit section stator 1000 and right two unit section stators 1200 should all be not more than
The length of magnetic-levitation train half；Exclusive or, when a train is made of four section compartments, the length of flat stator section is two section compartments
Length, this advantageously reduces induced electromotive force.As another example, when a train is made of six section compartments, the second from left unit section stator
1100, the length of the first from left unit section stator 900, a right unit section stator 1000 and right two unit section stators 1200 should all be not more than
The length of magnetic-levitation train half；Exclusive or, when a train is made of six section compartments, the length of flat stator section is three section compartments
Length.
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.
In the present invention, when unit section stator is specially three groups, the length of any one unit section stator is magnetic suspension column
The one third of the length of vehicle.That is, it is floating that the length of linear motor stator electric should be magnetic when a train is made of six section compartments
The length in two section compartment of train；Exclusive or, when a train is made of six section compartments, continuously arranged three groups of unit sections stator is (straight
Line motor stator) length in a column magnetic suspension train (six section compartments) can be covered just.
Every section of linear motor long stator and adjacent linear motor long stator do not constitute physical connection, this can be same
On route, multiple magnetic-levitation trains run create conditions simultaneously.Such as when there is a column magnetic-levitation train to operate at the uniform velocity section 1, this
When magnetic-levitation train power supply by DC/AC inverter 100,200,300,400 power, if another train at the uniform velocity section 2 transport
Row, then its power supply is powered by DC/AC inverter 3700,3800,3900,4000.Since the current speed of each train is different,
Speed is controlled by frequency, electric current of linear motor long stator etc..Such as in existing power supply system Fig. 1, due to entire route
Or multiple sections are all by same set of inverter power supply, then by powering after switch control to linear motor long stator, just certainly
Single-row train operation can only exactly be allowed by having determined the power supply section.And the present invention can be run while have vehicle at the uniform velocity section 1
At the uniform velocity run in section 2.
The distance between inverter 100,200,300,400 and linear motor long stator 900,1000,1100 and 1200 will
It is as short as possible, it on the one hand can shorten the length of service cable 500,600,700,800, reduce the protection cost and line of high voltage
Route cable cost.It on the other hand should be by 900,1000,1100 and of inverter 100,200,300,400 and linear motor long stator
1200 form modular design, promote convenient for engineering.Other section of design also has this requirement.
Exclusive data communication line 4900,5000,5100 and 5200 be mainly used to certain condition transmit be connected inverter it
Between data information.For example exclusive data communication line 4900 is used to transmit DC/AC inverter 100 and 200 and DC/AC inverter
The relevant informations such as phase, electric current and frequency between 1300 and 1400.
As shown in Figure of description 4, the structural representation of the still another embodiment of power supply system is floated for a kind of magnetic of the present invention
Figure correspondingly, for inverter share, be applied to thinking and extend at the uniform velocity section.Assuming that there is tri- sections B-A-C, B-A it
Between there are three at the uniform velocity section, each segment length 2km, A platform areas, between braking section and accelerating sections (containing station section) each 1.5km, A-C
It is three at the uniform velocity sections, and each segment length is also 2km.
Above-mentioned section is altogether there are three inverter 0201,0202 and 0203 of powering, and wherein inverter 0201 is responsible for giving the section B-A
Three at the uniform velocity sections power；0202 for braking section and accelerating sections (containing station section) power supply to station A；0203 for A-C
The at the uniform velocity section of three of section is powered.The output of inverter 0201 passes through service cable by three control switch 0207-0209
0204-0206 is connected at the uniform velocity section linear motor long stator 0210-0212.
The output of inverter 0202 is connected to by service cable 0213-0214 and is subtracted by control switch 0215 and 0216
Fast section linear motor long stator 0217 and acceleration area linear motor long stator 0218.
The output of inverter 0203 is connected by three control switches 0222,0223 and 0224 by service cable 0219-0221
It is connected at the uniform velocity section linear motor long stator 0225-0227.
When the station C is driven towards at the slave station B of magnetic-levitation train 0228, rate-determining steps are as follows:
Control switch 0207,0215 and 0222 is closed when initial.
Step 1: magnetic-levitation train 0228 is after B platform is completed to accelerate, into 0210 linear motor long stator section, if speed
Not up to the maximum speed of train operation when, can continue to accelerate.If having had reached the maximum speed of service requirement, tie up
It holds at the uniform velocity.
Step 2: when magnetic-levitation train has half to enter 0211 section, 0207 is disconnected, and 0208 closure, magnetic-levitation train continues even
Speed operation.Power can occur in the moment of switching and lose half, be 150km/h-250km/h according to speed, if maglev vehicle
Total length be 4*25=100 meter, therefore power lose half time about 1.45s-2.39s, therefore will not influence vehicle transport
Row.
Step 3: when 0212 section of magnetic-levitation train, the movement of control switch 0208 and 0209 is similar with step 2.
Step 4: when 0217 section of magnetic-levitation train, B-A inverter is consistent with the current characteristics of the station A inversion output at this time, because
During entering 0217 power loss will not occur for this vehicle.Magnetic-levitation train is completely into after 0217 section, control switch
0209 disconnects, and 0207 is switched to closure, provides condition for the entrance of the lower train in the section B-A.Magnetic-levitation train is in 0217 section of straight line
Motor long stator runs slowly.
Step 5: when magnetic-levitation train has half to enter 0218 section, 0217 is disconnected, 0208 closure, in the moment meeting of switching
Power occurs to lose, but magnetic-levitation train is to run slowly, therefore do not influence vehicle operation.Maglev vehicle will be parked in 0218 section,
Complete passenger getting on/off.
Step 6: after magnetic-levitation train completes passenger getting on/off and receives outbound signaling, Accelerating running will be started, A stands at this time
Platform inverter maximum output current is very big, it is contemplated that maximum can reach 1800A.
Step 7: magnetic-levitation train enters 0225 section of process, and the movement of the section A-C inverter and its control switch and magnetic are floating
B-A inverter and its control end consistent when train enters the section B-A.Step 1-6 is repeated, and enters next station.
From the above process it is recognised that theoretically, allowing to there is magnetic-levitation train to operate in the section B-A, the station A simultaneously on route
With the section A-C.Certainly this needs speed and headway in conjunction with vehicle rationally to be arranged, and guarantees the safety of vehicle
Property and continuity.
It using the mode of such setting, runs and creates condition simultaneously for more vehicles on route, be conducive to the passenger for promoting route
Conveying capacity.
By sharing the thinking of inverter, that is, the high-pressure delivery disadvantage of the centrally connected power supply avoided, and utmostly save
The configuration of route inverter, reduces the investment and construction cost of route.
Since magnetic-levitation train is run, it is necessary to power by the long stator of linear motor, switch over control by control switch
System improves the safety of route vehicle operation again from another point of view.
If illustrated shown in attached drawing 5, the detailed construction schematic diagram in a section of power supply system is floated for a kind of magnetic of the present invention,
It is the deep expansion and refinement to attached drawing 3.
