The luminance of lamp controls the dynamic of peripheral J1 A.C. contactors and J2 A.C. contactors by the J4 switching controls relay
Make, so as to carry out the automatic switchover of dual input power supply, ensure the constant of out-put supply；A roads power supply sampling mold in figure
AC power can be converted into DC low voltage power supply by block, B roads power supply sampling module and power supply output sampling module, the J3 in figure
Instruction control relay and J4 switching control relays are at involution state, and relay can be changed by pressing setting button
Contacts status；The actuation coil and involution coil of the J3 instructions control relay and J4 switching control relays are all not powered on,
Four groups of contacts are held at the state that a is connected with b, d and e, and the work of circuit at this time has following three kinds of states：
The first is that dual input power supply has electricity condition, and A roads electric power incoming line and B roads electric power incoming line light A roads respectively to be had
There is electric indicator light on electric indicator light and B roads, and B roads electric power incoming line also makes B roads sampling module obtain power supply, and makes output DC power supply V3
J5 relay coils are connected, disconnect contact J5-1；The L1 of A roads electric power incoming line connects J1 A.C. contactors by d1, d17
One end with J2 ac contactor coils and after connecing, N1 connect two with d16 by d2, J4 control relay bottom contacts e, d
Ac contactor coil and the other end after connecing, such J1 and J2 ac contactor coils make after being powered J1-1, J2-1 be attracted and
J1-2, J2-2 are disconnected, and L1, the N1 for just forming A roads electric power incoming line are connected with Lo, No of power output end and made B roads power supply respectively
Inlet wire and out-put supply off-state, at this time output indicator light；Output electricity is sent into after out-put supply is obtained at d18, d19 end
The input terminal of source sampling module, output positive voltage V1 fill C1 capacitances after R1, d7, the normally-closed contact for setting button, d8
Electricity, V1 also by the d and e, d5 of R4, J3 instruction control relay, go driving to light the preferential indicator light in A roads；At this moment if pressed
Button is once set, its normally opened contact 3 is just made to be connected with common end 2, the charge on C1 capacitances is connected to J3 instruction controls by d9
One group of contact a ends and b ends above relay processed are applied to the A ends of J3, J4 actuation coil using R2 resistance, this triggering arteries and veins
Punching makes four groups of contacts of two magnetic latching relays all act conversion, and state remains unchanged after pulse disappearance, at this time J3
It disconnects with a and b of J4 and is connected with c, d and e is disconnected and connected with f；Make the preferential indicator light extinguishing in A roads, d10 after leading to d5 dead electricity
It is electric after light the preferential indicator light in B roads, while d16 ends lose the connection with d2 ends, lead to J1 and J2 alternating current contactors
Coil lose power supply, so as to disconnect J1-1, J2-1 and J1-2, J2-2 are attracted, just form L1, N1 points of A roads electric power incoming line
It is not disconnected with Lo, No of power output end and makes B roads electric power incoming line and out-put supply on-state, at this time A roads power supply sampling mold
Block also loses power supply when being disconnected with d2, and V2 is made to be low level, makes to be powered indicator light extinguishing by the A roads that d4 drive, the low electricity of V2
Output that is flat and making level inverter IC is high level, is driven after d12 and lights B roads power supply indicator light；If it at this moment presses again
Primary setting button, the involution coil that the charge on C1 capacitances will be applied to J3, J4 relay by a and c of J3, using R3
Upper end, four groups of contacts is made to be returned to the state that A roads preferentially power；If the input power-off of B roads is powered off rear and restores to have
Electricity does not affect A roads and inputs to output power supply；But when being provided that B roads preferentially power, if B input power-off will cause J5
The J5-1 contactings of relay so that J1 and J2 ac contactor coils are powered and 4 contacts is made to change, and realize A roads
Input is automatically switched to powers to output；If B roads restore have electricity after switching, under the priority status of setting B roads, because of J5 relays
J5-1 contacts disconnect and still restore B roads and input to power to output..
Second is that A roads input power powers off, B roads input power has electricity condition, and A roads have electric indicator light to extinguish at this time, B roads
There is electric indicator light that can light, supply J1, J2 ac contactor coil power supply disappearance Hou Ge roads contacts are in be disconnected in J1-1, J2-1
With J1-2, J2-2 attracted position, L1, the N1 for being similarly formed A roads electric power incoming line are disconnected with Lo, No of power output end and are made respectively
B roads electric power incoming line and out-put supply on-state, it is low level that at this moment power supply sampling module in A roads equally exports V2 due to dead electricity,
Thus power supply indicator light in A roads extinguishes, B roads power supply indicator light is lighted；The state of two preferential indicator lights will determine by setting button,
When being such as in A roads at this time and preferentially powering, since J3 indicates that the d and e of control relay are connected and disconnected with f, V1 power supplys are by R4
The driving preferential indicator light in A roads is lighted, and the preferential indicator light in B roads extinguishes when losing power supply；Then if pressing setting button again,
The actuation coil of J3 and J4 relays because obtain C1 capacitances release pulse voltage due to four groups of contacts is made all to change, a of J3
It prepares after being connected with c to provide the pulse acted on involution coil next time, the d on J3 and f is connected so that A roads are preferential
Indicator light extinguishes, lights the preferential indicator light in B roads, but because A roads inlet wire does not have a power supply, no matter J4 relays d, e,
How f contacts convert, and do not affect the working condition of J1, J2 A.C. contactor, are also maintained for B roads power supply and connect out-put supply
State；When being provided that A roads are preferential, then when restoring electricity on A roads, make due to d, e contact of J4 relays are on
J1 and J2 ac contactor coils are powered, and the input of similary realization A roads is automatically switched to powers to output；If it is provided that B roads
Preferentially, then A roads restore have the electric B roads that do not influence to input to output power supply..
The third is that A roads input power has electricity, B roads input power off-position, and A roads have electric indicator light to light at this time, B roads
There is electric indicator light that can extinguish；Since B roads electric power incoming line loses power supply so that B roads sampling module also loses power supply, and makes connection defeated
Go out the J5 relay coils power-off of DC power supply V3, connect contact J5-1；Figure 4, it is seen that J4 switching control relays
