During any one incoming line module power supply trouble, another incoming line module and mother module energy normal power supply.
In described 1# incoming line module, mother module and 2# incoming line module in its cocircuit in addition to under-voltage loop,
Relay and the coiler part of chopper and each display lamp are connected to the position near zero line N.
Three circuit breaker Q L1, QL2, QL3 in described 1# incoming line module, mother module and 2# incoming line module
By closing circuit and the manually interlocking extension loop electrical interlocks of mother module of three modules, can only be most
Two choppers close a floodgate simultaneously.
As it is shown in figure 9, in specific implementation process, Non-follow control can be selected the most voluntarily or automatically controls
System, when carrying out Non-follow control, first invests zero-bit position by manual/auto permutator 1SS5,2SS5,3SS5
Put, when the power supply feeding 1# incoming line module and 2# incoming line module is all normal, can respectively with two ends power supply to being
System power supply, manual/auto permutator 1SS5,2SS5,3SS5 are pulled to manual position, press combined floodgate by
Button 1S1,2S1,3S1, frame circuit breaker QL1, QL2 close a floodgate when load-side fault-free, due to electrically
Interlocking, the frame circuit breaker QL3 in mother module now cannot close a floodgate, and this avoid two ends inlet wire
System paired running is caused fault.When feeding 1# incoming line module or arbitrary power loss of 2# incoming line module
After, frame circuit breaker QL1 or QL2 disconnects one voluntarily due to decompression, now can be manually pressed by switch knob
Frame circuit breaker QL3 is closed a floodgate by 3S1.Realize single ended power supply to system power supply.When feed 1# incoming line module and
When the power supply of 2# incoming line module all restores electricity, to first be manually pressed by 3S2 opening button and disconnect mother module
After chopper, the chopper of the incoming line module that could again close, recovers respectively with the power supply pair of two incoming line modules
System power supply.
When automatically controlling, 1SS5,2SS5,3SS5 permutator is invested automated location, carries out and haul oneself willingly into
Runback prepares.
Haul oneself willingly into: when the power supply feeding 1# incoming line module and 2# incoming line module is all normal, automatically throw upper 1# inlet wire
Frame circuit breaker QL1 and QL2 of module and 2# incoming line module, respectively two ends power supply is to system power supply.If
Feed the power loss of 1# incoming line module, then disconnect framework open circuit by the coil without tension of frame circuit breaker QL1
Device QL1 switchs.In load-side fault-free, and in the case of being not manual brake separating, in 1# incoming line module, standby throwing is opened
The time-delay contact JDK1 of the time relay 1K4 in dynamic loop is also in conjunction position makes the line of auxiliary reclay 1K3
Enclose electric, then closed and mother QL3 open circuit of automatically closing by the normally opened contact JDK1 of auxiliary reclay 1K3
Device.Now by the whole load of Power supply belt feeding 2# incoming line module；If feeding the power loss of 2# incoming line module,
Then disconnect frame circuit breaker QL2 by the coil without tension of frame circuit breaker QL2 to switch.In load-side fault-free,
And in the case of being not manual brake separating, the time delay of the standby time relay 2K4 throwing starting-up later time in 2# incoming line module
Contact JDK2 is also in conjunction position, and to make the coil of auxiliary reclay 2K3 obtain electric, then by auxiliary reclay 2K3
Normally opened contact JDK2 Guan Bi and the mother QL3 chopper that automatically closes.Now by the electricity feeding 1# incoming line module
The whole load of source band.(require the delay time of the time relay 1K4,2K4 is set to 10-180S, be more than
The inlet wire decompression time, to ensure that in mother module, QL3 switch has time enough to close a floodgate.)
Runback: when feeding the power up of 1# incoming line module, frame circuit breaker QL1 is under-voltage, and coil Q1 obtains electric,
Possessing condition of can closing a floodgate, now frame circuit breaker QL1 is also at open position, but there is power supply end of incoming cables, makes
Time relay 1K7 coil obtains electric, then automatic by the normally opened contact JDK2 Guan Bi of time relay 1K7
Tripping bus QL3.(determined by the delay time of time relay 1K7 through time delay after a while,
Ensure that frame circuit breaker QL3 completely disconnects), the time-delay contact JDK1 of closing time relay 1K7 is from dynamic circuit connector
Upper frame circuit breaker Q L1 switchs；When feeding the power up of 2# incoming line module, frame circuit breaker QL2 owes
Line ball circle Q2 obtains electric, possesses condition of can closing a floodgate, and now frame circuit breaker QL2 is also at open position, but enters
Line end has power supply, makes time relay 2K7 coil obtain electric, then by the normally opened contact of time relay 2K7
JDK2 closes and automatic tripping bus QL3.Through time delay after a while (by time relay 2K7
Delay time fixed, it is ensured that frame circuit breaker QL3 completely disconnects), the time delay of closing time relay 2K7
Contact JDK1 automatically close frame circuit breaker QL2 switch.
Load side fault: when 1# incoming line module is powered normal, when breaking down such as power supply load side, framework breaks
Road device QL1 switch trip, due to over current fault and fault contact CK1 of instruction loop middle frame circuit breaker Q L1
Guan Bi, makes auxiliary reclay 1K2 coil obtain electric, by disconnecting the normally-closed contact JDB2 of auxiliary reclay 1K2
Making auxiliary reclay 1K3 coil losing electricity in standby throwing starting-up later time, frame circuit breaker QL3 switch will not be automatic
Close a floodgate, it is achieved error protection；When 2# incoming line module is powered normal, when breaking down such as power supply load side, frame
Frame circuit breaker Q L2 switch trip, owing to the fault of over current fault and instruction loop middle frame circuit breaker Q L2 is touched
Point CK1 Guan Bi, makes auxiliary reclay 2K2 coil obtain electric, touches by disconnecting the normally closed of auxiliary reclay 2K2
Point JDB2 makes auxiliary reclay 2K3 coil losing electricity in standby throwing starting-up later time, and frame circuit breaker QL3 switchs not
Meeting automatic closing, it is achieved error protection；During mother module generation over current fault, due to over current fault and instruction
The fault contact CK1 Guan Bi of loop middle frame circuit breaker Q L3, makes auxiliary reclay 3K2 coil obtain electric, female
In the closing circuit of gang mould block, the normally-closed contact of auxiliary reclay 3K2 disconnects, and frame circuit breaker QL3 will not be certainly
Dynamic circuit connector lock, it is achieved error protection.
Manual brake separating: after 1# incoming line module normal manual separating brake, frame circuit breaker QL1 trips, due to centre
Relay 1K5 coil obtains electric, and auxiliary reclay 1K3 coil losing electricity in standby throwing starting-up later time, in mother module
Frame circuit breaker QL3 switch will not automatic closing, remain powered off state；Same 2# incoming line module normal manual
After separating brake, frame circuit breaker QL2 trips, owing to auxiliary reclay 2K5 coil obtains electric, and standby throwing starting-up later time
Middle auxiliary reclay 2K3 coil losing electricity, mother module middle frame circuit breaker Q L3 switch will not automatic closing,
Remain powered off state.
When fault or manual brake separating power-off, when failture evacuation need to restore electricity, need to first press and close
Lock releases button 1S3/2S3/3S3 and releases standby throwing locking.
