As a kind of preferred embodiment of the invention, the clock signal device 7 generates corresponding level according to voltage waveform
In the period of conversion, when voltage generates oscillation, the clock signal device 7 re-starts the change in level conversion period.
In the specific implementation process, when system carries out change distribution, electricity that external cable 3 supplies external power supply unit
Pressure is applied to transformer 4, and the transformer 4 at station is voltage to be fixed transformation, the electricity that transformer 4 provides external cable 3
In normal range (NR) corresponding to low-voltage distribution of the pressure drop down to station;After being depressured via transformer 4, distribution box 5 is to all connections
Distribution is carried out in the operational module 2 of power module 1.
For each operational module 2, staff according to operational module 2 in previous historical record when different
Between carry out each operational module 2 under section and different external world situations needed for distribution voltage supposition, for estimation result, work
Module 2 is recorded by computer 12.
Wherein, within the common period, operational module 2 relatively stable can work under an operating voltage, thus
So that the distribution voltage of each operational module 2 keeps stablizing;And when there are some specific situations, such as pull in,
Distribution voltage needed for certain operational modules 2 will increase, and before train enters the station, train can inform station, and station connects
Information that train enters the station is transmitted to corresponding operational module 2 after receiving train signal, such as when No.1 track has train to enter the station, column
Vehicle sends information to the corresponding operational module 2 of No.1 track, and the voltage total value range of the corresponding operational module 2 of No.1 track can root
Increased voltage carries out corresponding adjustment when entering the station accordingly toward identical train, so that distribution needed for the operational module 2 is electric
Pressure increases.
After distribution box 5 distributes voltage to operational module 2, illustrated with an operational module 2, if having in operational module 2
It works load 8, such as has workload 8A, workload 8B, workload 8C respectively, workload 8A is connected with breaker
6A, second level bleeder mechanism 11A and supercapacitor 9A, workload 8B be connected with breaker 6B, second level bleeder mechanism 11B with
And supercapacitor 9B, workload 8C are connected with breaker 6C, second level bleeder mechanism 11C and supercapacitor 9C.
When normal operating voltage, which occurs, in workload 8A to be risen, such as when train enters the station, distribution box 5 can be according to this
The change situation of the model judgement partial pressure of train, i.e., distribute No.1 operational module 2 corresponding to No.1 track obtained voltage
Carry out raising to a certain extent;For improve No.1 operational module 2 branch pressure voltage, can when total line is set
Multiple rheostats are arranged in total line to be divided, to reduce variable resistance when some operational module 2 needs to improve branch pressure voltage
The partial pressure of device, so that the voltage that operational module 2 obtains improves.
After No.1 operational module 2 improves voltage, the corresponding level-one bleeder mechanism 10 of No.1 operational module 2 can be according to work
Raising on 2 voltage of module divides voltage required for workload 8, for example, if when current train enters the station, train into
The workload 8A to stand in corresponding operational module 2 enters the station to train and works with system to a certain extent, at this point, work is negative
It carries voltage required for 8A to increase, level-one bleeder mechanism 10 judges that No.1 operational module 2 is facing according to the model of the secondary train
The promotion of secondary train operating voltage required for provided working condition when entering the station, since distribution box 5 is for train
Corresponding No.1 operational module 2 carries out voltage increment distribution when entering the station, therefore level-one bleeder mechanism 10 can be directly in No.1 work
Make to divide the voltage value that workload 8A is connected into again in module 2.
And after train is completely outbound and is detached from the process range at current station, it just judges needed for time train enters the station
The extra work to be carried out terminates, at this point, restored for the voltage of workload 8A and No.1 operational module 2, into
When row restores, the voltage reduction of distribution box 5 is first carried out, after voltage reduction, then carries out the distribution voltage of level-one bleeder mechanism 10 also
It is former.
When not having train to enter the station when the power supply of external cable 3 generates certain fluctuation, external cable 3 is straight
The transformation voltage of the transformer 4 connect in succession also will appear it is certain stir, provided due to the reduced external cable 3 of transformer 4
The fluctuation situation of gap between the maximum and minimum of voltage, the transformation voltage of 4 final output of transformer can be than external electricity
The fluctuation situation for the voltage value that cable 3 is directly fed is smaller;Distribution box 5 is during distribution, since supply voltage change is wink
Duration, and distribution box 5 is adjusted according to the range of the voltage total value of operational module 2 with certain hysteresis quality, therefore,
Distribution box 5 can still have fluctuation to the distribution of the voltage of each operational module 2.
Since supercapacitor 9 and workload 8 are connected to level-one bleeder mechanism 10, pass through in workload 8
When the voltage that level-one bleeder mechanism 10 is divided and provided is worked, also carried out with work clothes in corresponding supercapacitor 9
Charging, when there is voltage to when high voltage fluctuation, level-one bleeder mechanism 10 also has one to the voltage that each workload 8 is distributed
Determine it is higher in degree, when deviation is in stability range, i.e., under the partial pressure limit of second level bleeder mechanism 11, second level partial pressure
Device 11 distributes superfluous a part of voltage to supercapacitor 9, to guarantee that workload 8 can continue work.
It is noted that being divided into two parts, for example, right for the corresponding supercapacitor 9 of each workload 8
In the corresponding supercapacitor 9A of workload 8A, it is divided into supercapacitor 9A-1 and supercapacitor 9A-2, when voltage is inclined
When difference is more than stability range, for example, level-one bleeder mechanism 10, which is distributed to the voltage of workload 8A, to be surpassed for workload 8A
The partial pressure limit of second level bleeder mechanism 11A is crossed, at this point, breaker 6A disconnects second level bleeder mechanism 11A's and workload 8A
Connection, disconnects supercapacitor 9A-2 and workload 8A at the connection for disconnecting supercapacitor 9A-1 and second level bleeder mechanism 11A
Connection.
At this point, second level bleeder mechanism 11A is also attached to supercapacitor 9A-2, supercapacitor 9A-1 is also attached to work
8A is loaded, therefore, supercapacitor 9A-1 and workload 8A are formed into a loop, and supercapacitor 9A-1 can discharge, i.e., super electricity
Container 9A-1 case workload 8A is powered, and workload 8A is able to continue to execute work, and supercapacitor 9A-2 can be after
The voltage of second level bleeder mechanism 11A distribution is received in continued access, is charged;For supercapacitor 9, breakdown voltage is greater than transformer 4
Maximum transformation value therefore for supercapacitor 9A-1 and supercapacitor 9A-2, can individually receive second level well
The voltage of bleeder mechanism 11A distribution.
And for supercapacitor 9A-1 and supercapacitor 9A-2, one is individually connected to workload 8A wherein
Afterwards, when discharge process will enter coda, i.e. the charge retained on supercapacitor 9A-1 or supercapacitor 9A-2 will be used
When complete, breaker 6A is by supercapacitor 9A-1 and supercapacitor 9A-2 and second level bleeder mechanism 11A and workload
The connection state of 8A is exchanged.
In practical applications, DC communication electrical switching device can be connected in supercapacitor 9, thus by super capacitor
The direct current that device 9 issues when powering is converted to alternating current.
Wherein, for the fluctuation of voltage, judged by clock signal.By voltage regulator circuit by level-one bleeder mechanism 10
The voltage of distribution is stablized, and the voltage waveform after stablizing levels off to the SIN function of standard, and therefore, the waveform of voltage has
In one fixed period, under stable period, clock signal device 7 can generate the level signal in corresponding period according to the period and convert
Situation, setting real-time voltage be higher than 0 when be used as high level, and real-time voltage be 0 when as low level, therefore, in the status of criterion
Under, voltage cycle is consistent with the level translation period, and in one cycle, the duration of high level and the electricity for being higher than 0
The continuous time consistency of pressure holding, low level duration are consistent with the voltage-duration lower than 0.
Therefore, voltage waveform in the individual period is subjected to corresponding in real time, the process with clock signal level change over condition
That is the low and high level of the clock signal of the sending of clock signal device 7 is defined the waveform of branch pressure voltage, and branch pressure voltage includes
The partial pressure of distribution box 5 and the partial pressure of level-one bleeder mechanism 10.
In voltage output, computer 12 obtains clock signal and voltage waveform simultaneously, since clock signal is stable
, computer 12 directly judges the situation of voltage at this time by correspondence situation of the control voltage waveform under clock signal, for example,
When clock signal is high level and when time point is N, judge that the phase angle of the corresponding voltage of time point N does not change, and it is electric
When the value of pressure becomes larger, the voltage in judgement overall at this time power module 1 and operational module 2 is larger, and voltage occurs longitudinal flat
It moves;
And when judging the phase angle lead of the corresponding voltage of time N or falling behind, directly voltage occurs laterally at this time for judgement
Translation;For the time point of certain voltage translation situation occurs, system reaches the partial pressure limit according to above-mentioned second level bleeder mechanism 11
When counter-measure coped with, wherein when there is horizontal line translation, further judgement is vibrated, processing vibrate after when carrying out
Clock signal and the record again in level conversion period, and alternate simultaneously.
