As shown in Figs. 9 to 11, in specific implementation process, can Non-follow control be selected as required voluntarily or automatically control, when carrying out Non-follow control, first by manual/auto change over switch 1SS5, 2SS5, 3SS5 invests null positions, when the power supply feeding 1# incoming line module and 2# incoming line module is all normal, can two ends power supply be used respectively to system power supply, by manual/auto change over switch 1SS5, 2SS5, 3SS5 pulls to manual position, press switch knob 1S1, 2S1, 3S1, frame circuit breaker QL1, QL2 closes a floodgate when load-side fault-free, due to electrical interlocks, frame circuit breaker QL3 in mother module now cannot close a floodgate, this avoid two ends inlet wire and fault is caused to system paired running.When after the arbitrary power loss feeding 1# incoming line module or 2# incoming line module, frame circuit breaker QL1 or QL2 disconnects one voluntarily due to decompression, now manually can press switch knob 3S1 and be closed a floodgate by frame circuit breaker QL3.Realize single ended power supply to system power supply.When the power supply feeding 1# incoming line module and 2# incoming line module all restores electricity, after first manually will pressing the circuit breaker of 3S2 opening button disconnection mother module, again could be closed the circuit breaker of incoming line module, recovers to use the power supply of two incoming line modules to system power supply respectively.
When automatically controlling, 1SS5,2SS5,3SS5 change over switch is invested automated location, carry out and haul oneself willingly into runback preparation.
Haul oneself willingly into: when the power supply feeding 1# incoming line module and 2# incoming line module is all normal, frame circuit breaker QL1 and QL2 of 1# incoming line module and 2# incoming line module on automatic switching, is respectively two ends power supply to system power supply.If feed the power loss of 1# incoming line module, then disconnect frame circuit breaker QL1 switch by the coil without tension of frame circuit breaker QL1.In load-side fault-free, and be not in manual brake separating situation, in 1# incoming line module, the standby time-delay contact JDK1 throwing the time relay 1K4 of starting-up later time is also in co-bit and puts that the coil of auxiliary relay 1K3 is obtained is electric, then closed by the normally opened contact JDK1 of auxiliary relay 1K3 and the mother QL3 circuit breaker that automatically closes.Now by the whole load of Power supply belt feeding 2# incoming line module; If feed the power loss of 2# incoming line module, then disconnect frame circuit breaker QL2 switch by the coil without tension of frame circuit breaker QL2.In load-side fault-free, and be not in manual brake separating situation, in 2# incoming line module, the standby time-delay contact JDK2 throwing the time relay 2K4 of starting-up later time is also in co-bit and puts that the coil of auxiliary relay 2K3 is obtained is electric, then closed by the normally opened contact JDK2 of auxiliary relay 2K3 and the mother QL3 circuit breaker that automatically closes.Now by the whole load of Power supply belt feeding 1# incoming line module.(require the delay time of the time relay 1K4,2K4 to be set to 10-180S, be greater 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, possesses 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, make time relay 1K7 coil obtain electric, then closed and automatic tripping bus QL3 by the normally opened contact JDK2 of time relay 1K7.Through time delay after a while (fixed by the delay time of time relay 1K7, to ensure the complete disconnection of frame circuit breaker QL3), the time-delay contact JDK1 of closing time relay 1K7 closes frame circuit breaker QL1 switch automatically; When feeding the power up of 2# incoming line module, frame circuit breaker QL2 is under-voltage, and coil Q2 obtains electric, possesses condition of can closing a floodgate, now frame circuit breaker QL2 is also at open position, but there is power supply end of incoming cables, make time relay 2K7 coil obtain electric, then closed and automatic tripping bus QL3 by the normally opened contact JDK2 of time relay 2K7.Through time delay after a while (fixed by the delay time of time relay 2K7, to ensure the complete disconnection of frame circuit breaker QL3), the time-delay contact JDK1 of closing time relay 2K7 closes frame circuit breaker QL2 switch automatically.
Load side fault: when 1# incoming line module is powered normal, as power supply load side break down time, frame circuit breaker QL1 switch trip, because the fault contact CK1 of over current fault and instruction loop middle frame circuit breaker Q L1 closes, auxiliary relay 1K2 coil is made to obtain electric, make standbyly to throw auxiliary relay 1K3 coil losing electricity in starting-up later time by the normally-closed contact JDB2 disconnecting auxiliary relay 1K2, frame circuit breaker QL3 switch can not automatic closing, realizes error protection; When 2# incoming line module is powered normal, as power supply load side break down time, frame circuit breaker QL2 switch trip, because the fault contact CK1 of over current fault and instruction loop middle frame circuit breaker Q L2 closes, auxiliary relay 2K2 coil is made to obtain electric, make standbyly to throw auxiliary relay 2K3 coil losing electricity in starting-up later time by the normally-closed contact JDB2 disconnecting auxiliary relay 2K2, frame circuit breaker QL3 switch can not automatic closing, realizes error protection; During mother module generation over current fault; because the fault contact CK1 of over current fault and instruction loop middle frame circuit breaker Q L3 closes; auxiliary relay 3K2 coil is made to obtain electric; in the closing circuit of mother module, the normally-closed contact of auxiliary relay 3K2 disconnects; frame circuit breaker QL3 can not automatic closing, realizes error protection.
Manual brake separating: after 1# incoming line module normal manual separating brake, frame circuit breaker QL1 trips, because auxiliary relay 1K5 coil obtains electric, and auxiliary relay 1K3 coil losing electricity in standby throwing starting-up later time, mother module middle frame circuit breaker Q L3 switch can not automatic closing, keeps off-position; After same 2# incoming line module normal manual separating brake, frame circuit breaker QL2 trips, because auxiliary relay 2K5 coil obtains electric, and auxiliary relay 2K3 coil losing electricity in standby throwing starting-up later time, mother module middle frame circuit breaker Q L3 switch can not automatic closing, keeps off-position.
For the situation of fault or manual brake separating power-off, when failture evacuation need restore electricity, first need press lock release button 1S3/2S3/3S3 and remove and standbyly throw locking.
Although be below described preferred embodiment of the present utility model by reference to the accompanying drawings; but the utility model is not limited to above-mentioned embodiment; above-mentioned embodiment is only schematic instead of determinate; those of ordinary skill in the art is under enlightenment of the present utility model; under the prerequisite without prejudice to the utility model aim and claim; can make like multiple types and representing, such conversion all falls within protection range of the present utility model.
