High-tension electricity inputs the first subordinate inverter SIV1 by high voltage bus, through the first subordinate inverter
The inversion of SIV1, to middle pressure bussed supply, first coil K1 is passed through to become pressure exchange electricity output in three-phase
Middle pressure bus is connected with the outfan of the first subordinate inverter SIV1, because three-phase alternating current respectively mutually has phase
Difference, therefore, first coil K1 is only connected composition loop with two in three-phase alternating current can normal work
Make, thus, when the first subordinate inverter SIV1 has alternating current normally to export, the first power on circuitry, the
One coil K1 energising, when the first subordinate inverter SIV1 no exchanges electricity output, the first circuit no power,
First coil K1 no power.
High-tension electricity inputs the second subordinate inverter SIV2 by high voltage bus, through the second subordinate inverter
The inversion of SIV2, to middle pressure bussed supply, the second coil K2 passes through to become pressure exchange electricity output in three-phase
Middle pressure bus is connected with the outfan of the second subordinate inverter SIV2, because three-phase alternating current respectively mutually has phase
Difference, therefore, the coil of the second chopper is only connected composition loop with two in three-phase alternating current can be just
Often work, thus, when the second subordinate inverter SIV2 has alternating current normally to export, second circuit is energized,
Second coil K2 energising, when the second subordinate inverter SIV2 no exchanges electricity output, second circuit is obstructed
Electricity, the second coil K2 no power.
First contactor main contacts KMK by middle pressure bus respectively with the first subordinate inverter SIV1 and the
The outfan of two subordinate inverter SIV2 is connected, when the first subordinate inverter SIV1 and the second auxiliary inversion
When device SIV2 is energized, first contactor main contacts KMK will not close, now the first subordinate inverter
SIV1 powers to the first circuit, and the second subordinate inverter SIV2 is powered to second circuit；When one of
During subordinate inverter no power, first contactor main contacts KMK closure, the first circuit and second circuit
Conducting, is powered to the first circuit and second circuit from the subordinate inverter normally run simultaneously, meets subway
The power demands of vehicle.
In above-mentioned connection, whether can be energized by the first chopper and the second chopper and verify the first auxiliary
Inverter SIV1 and the second subordinate inverter SIV2 whether normal work, it is to avoid subordinate inverter software
The unreliability of detection.
Specifically, as shown in Figure 2, described control circuit by DC power control and includes the 3rd open circuit
Device, described 3rd chopper includes tertiary coil K3 and the 3rd chopper main contacts K3K, and described first
Chopper also includes the first auxiliary contact, and described second chopper also includes the second auxiliary contact, and described
One catalyst also includes first contactor coil KM.
One end of described 3rd chopper main contacts K3K is connected with the positive pole of described DC source, and described
The other end of three chopper main contacts K3K is connected with described first auxiliary contact, described first contactor line
One end of circle KM is connected with described second auxiliary contact, the other end of described first contactor coil KM
It is connected with described DC power cathode；One end of described tertiary coil K3 is with described DC power cathode even
Connect, the other end of described tertiary coil K3 is connected with diagnostic system with railcar control；
Wherein, described first auxiliary contact include the first normally opened contact and the first normally-closed contact, and described second
Auxiliary contact include the second normally opened contact and the second normally-closed contact；Described first normally opened contact K11 with described
Second normally-closed contact K22 connects, described first normally-closed contact K12 and described second normally opened contact K21
Connect.
As shown in Figure 2, in this control circuit, only as the 3rd chopper main contacts K3K and first normal
When opening contact K11 and the second normally-closed contact K22 and being closed at, or as the 3rd chopper main contacts K3K
And the first normally-closed contact K11 and the second normally opened contact K21 when being closed at, control circuit just can turn on,
Unidirectional current is had to pass through, when electric current is through first contactor coil KM, first contactor main contacts KMK
Just can close.If in above-mentioned two situations, when having any element not close, control circuit all without
Unidirectional current is had to pass through, first contactor coil KM also will not be energized, thus first contactor main contacts
KMK will not close.
, the railcar auxiliary power supply of the present invention extends the expansion of system taking the circuit connecting mode of Fig. 2 as a example
Exhibition power supply mode is as follows：
In first circuit and second circuit, when first coil K1 and the second coil K2 are energized simultaneously, that is,
Two subordinate inverter normal works, the first subordinate inverter SIV1 and the second subordinate inverter SIV2 are all
High-tension electricity can be changed into middle pressure three-phase alternating current and normally exporting, two subordinate inverter can be to
Each circuit is powered.Now, the first chopper and the second chopper can notify TCMS by wireless signal
Do not need to be closed first contactor main contacts KMK.Even if now subordinate inverter software sends
Signal error, but because first coil K1 is all energized with the second coil K2, now the first chopper is in
Existing first state, i.e. the first normally opened contact K11 closure in control circuit, the first normally-closed contact K12 beats
Open；Second chopper assumes first state, and that is, in control circuit, the second normally-closed contact K22 opens, the
Two normally opened contact K21 closures.Therefore, in the case of being somebody's turn to do, control circuit does not turn on, and does not have unidirectional current to pass through,
First contactor coil KM will not be energized, thus first contactor main contacts KMK will not close, this
When, two subordinate inverter are powered to respective circuit.
In first circuit and second circuit, when the energising of first coil K1, when the second coil K2 is not powered on,
I.e. the first subordinate inverter SIV1 normal work, can by high-tension electricity be changed into middle pressure three-phase alternating current and
Normal output, the second subordinate inverter breaks down it is impossible to high-tension electricity is changed into middle pressure three-phase alternating current
And normally export.Now, the first chopper and the second chopper can notify TCMS by wireless signal
Need to be closed first contactor main contacts KMK, thus turning on the first circuit and second circuit,
So that the first subordinate inverter SIV1 is powered with second circuit for the first circuit simultaneously.Herein it should be pointed out that
It is, for extension this mode of power supply, when only one of which subordinate inverter normal work, in normal work
Before the subordinate inverter made is powered to two circuit at the same time, that is, before first contactor closure, TCMS
Need normal subordinate inverter is first responsible for the compressor of air conditioner off-load one of connection in that circuit powered
Half, it is closed again first contactor, then sequence starting fault subordinate inverter is responsible for that circuit powered
Middle connection half compressor of air conditioner.Therefore, after receiving close command, TCMS can first make
Air conditioner load off-load half in two circuit, after the completion of off-load, TCMS can persistently export the first extension and refer to
Order, this first extended instruction is high level, due to tertiary coil K3 one end and TCMS in control circuit
Connect, one end is connected with the negative pole of DC source, after TCMS output high level, the 3rd chopper
Coil will obtain electric, so that the 3rd chopper main contacts K3K closure, and first coil K1 and second
The "on" position of coil K2 makes the first chopper assume first state, that is, first normally opened in control circuit
Contact K11 closes, and the first normally-closed contact K12 opens；Make the second chopper assume the second state, that is, exist
Second normally-closed contact K22 closure in control circuit, the second normally opened contact K21 opens.Therefore, this situation
Under, control circuit turns on, and has unidirectional current to pass through, and first contactor coil KM obtains electric, thus first connects
Tentaculum main contacts KMK closes, and now, the first subordinate inverter SIV1 is powered to two circuit simultaneously.
Likewise, when the first subordinate inverter SIV1 fault, the second subordinate inverter SIV2 normal work
When having exchange electricity output, it is electric that the high level output of extended instruction makes tertiary coil K3 obtain, thus the 3rd is disconnected
Road device main contacts K3K closes, and the "on" position of first coil K1 and the second coil K2 makes first to break
Road device assumes the second state, and that is, in control circuit, the first normally opened contact K11 opens, the first normally-closed contact
K12 closes；The second chopper is made to assume first state, i.e. the second normally-closed contact K22 in control circuit
Open, the second normally opened contact K21 closure.Therefore, in the case of being somebody's turn to do, control circuit turns on, and has unidirectional current
Obtain electric through, first contactor coil KM, thus first contactor main contacts KMK closure, now,
Second subordinate inverter SIV2 is powered to two circuit simultaneously.
(for example, the first subordinate inverter SIV1 when a subordinate inverter is powered to two circuit simultaneously
Normally, the second subordinate inverter SIV2 fault), if when the second subordinate inverter SIV2 of fault is extensive
Multiple normal, now, first coil K1 with the second coil K2 and simultaneously electric, simultaneously in control circuit,
First normally opened contact K11 is still closure state, and the first normally-closed contact K12 is still open mode, and
Second normally-closed contact K22 is changed into open mode from closure state, and the second normally opened contact K21 is by open mode
It is changed into closure state, in the case of being somebody's turn to do, control circuit disconnects no unidirectional current and passes through, first contactor coil KM
No power, therefore first contactor main contacts KMK are opened, and air-conditioning recovers normal load, the first auxiliary
Inverter SIV1 powers to the first circuit, and the second subordinate inverter SIV2 is powered to second circuit.
The present invention passes through the chain triggering in electric elements, enhances the reliability of extension power-supply system, keeps away
Exempt to make power supply extension system go wrong because subordinate inverter software sends Wrong control signal.
Further, as shown in figure 3, another kind of railcar that provided by the embodiment of the present invention of Fig. 3
Auxiliary power supply extends the circuit connection diagram of system, also includes the of a first contactor in described control circuit
One normally opened auxiliary contact KM1, one end of the first normally opened auxiliary contact KM1 of described first contactor with
One end of described 3rd chopper main contacts K3K connects, and the first normally opened auxiliary of described first contactor is touched
The other end of point KM1 is connected with described first contactor coil KM.
During subway circulation, occur after the of short duration recovery of subordinate inverter often broken down again
Fault or two subordinate inverter occur replacing fault, once the subordinate inverter of fault is extensive for a long time
Multiple, first contactor main contacts KMK will open, and air-conditioning off-load also can recover normal, but of short duration
When breaking down after recovery again, air-conditioning off-load again, first contactor main contacts KMK closes again,
And so on for several times after, the damage of first contactor and air conditioning system can be caused.When in control circuit
After being provided with the first normally opened auxiliary contact KM1 of first contactor, due to the first contact in control circuit
First normally opened auxiliary contact KM1 of device is still in closure state, so still there being unidirectional current to flow through in this road
First contactor coil KM is made to be energized, so the first contactor master between the first circuit and second circuit
Contact KMK remains as energising closure state, does not disconnect immediately.Even if that is, in subway
In running, the second subordinate inverter SIV2 of fault recovers normal, but due to first in control circuit
The presence of the first normally opened auxiliary contact KM1 of catalyst, first contactor main contacts KMK also will not stand
Open, after the second subordinate inverter SIV2 of fault recovers certain duration, such as 1-3 minute,
First chopper and the second chopper can stop extension, now, TCMS by wireless signal order TCMS
The second extended instruction can be exported, this extended instruction is low level, after TCMS output low level, the 3rd
Coil K3 will power-off so that the 3rd chopper main contacts K3K disconnects, control circuit just no direct current
Electricity passes through, and due to first contactor coil KM power-off, first contactor main contacts KMK connects with first
First normally opened auxiliary contact KM1 of tentaculum just can disconnect, and air-conditioning recovers normal load, and the first auxiliary is inverse
Become device SIV1 to power to the first circuit, the second subordinate inverter SIV2 is powered to second circuit.
Further, as shown in figure 4, another kind of railcar that provided by the embodiment of the present invention of Fig. 4
