Start-up circuit get electric after, capacitor C 5A in the

pulse generator

1 and 2 and C5B begin charging because its time constant is different, and that the conducting voltage of G9 and G10 is respectively 0.6V is different with 1.2V, the conducting of G9 elder generation, pulse generator 1 sends a negative pulse, make the monostable circuit upset in the start-up circuit, relay J W3 adhesive, its contact JW3(1) the connection oscillator supply.JW3(2) the contact adhesive make G10 as yet not conducting promptly end.So not adhesive of relay J W4, JW4(1) closure makes the G10 remain off, JW4(3) open, JW4(2) closure, JW1 is in running order, and JW2 is in non operating state, this moment the oscillator starting oscillation, fashionable putting when making the JW1 relay along with frequency of oscillation (adjustable).Intermediate relay ZJ 1(1) contact fashionable putting also the time connected motor power, starter-generator or disconnect motor power, stop starter-generator, this is to consider generator because of various factors, and one-shot is success not necessarily, and be provided with restart control circuit.Start-up period is designed to start ten times (adjustable as required) if a start-up period generator still can not start among this embodiment, then monostable circuit is recovered, JW3 discharges, and oscillator is lost the job voltage and quit work, and sends the sound and light alarm signal simultaneously, if this moment is the words that the under-voltage lamp of battery does not work, then relight button AN1 can be pressed after one minute in the gap, carried out a start-up period again, so repeat, if start until the bright generator that still can not make of under-voltage indicator light.The utility model cuts off the working power of start-up circuit automatically, and generator can't be restarted, and at this moment checks failure cause immediately, in time get rid of, restart, make time relay JS1 adhesive, not delayed contact JS1(2 if start successful generator output) open, the start-up circuit dead electricity, no longer carry out startup work, behind the question generator output voltage stabilization, delayed contact JS1(1) closure, make the adhesive of CJ2 contactor, generator begins external power supply as described above.

Storage battery is a key element in the automatic power system, its performance quality, the operate as normal that directly influences whole system whether, so must at any time the fine or not situation of storage battery be monitored and charge, make storage battery be in best reserve or working condition always, in case damage, must provide the sound and light alarm signal immediately, be beneficial to user's on-call maintenance or replacing.To the charging of storage battery, when mains supply, by transformer B with the 220V ac buck after rectification to charge in batteries, and during grid power blackout, by generator with the output of 16V direct current to battery charge.The switching of the two charging realizes by A.C. contactor CJ3 and CJ4, CJ4 action (CJ3 is failure to actuate) during mains supply, CJ4(2) contact adhesive.By electrical network after the transformation rectification to charge in batteries, otherwise CJ3 action (CJ4 is failure to actuate) CJ3(1) closing of contact, by the output of generator 16V direct current to battery charge.The voltage detecting of storage battery is respectively by resistance R 34, potentiometer W4, resistance R 43, potentiometer W5(detects under-voltage) and resistance R 55.Potentiometer W6, resistance R 64, potentiometer W7(detect overvoltage) carry out.When cell voltage rises to 14.5V, the detected overvoltage of R34 in the pulse generator 3 and W4 makes the G15 conducting, and pulse generator produces a pulse and makes the upset of one of bistable circuit, JW5 adhesive, JW5(1) adhesive makes the JZ2 adhesive, to making ZJ2 adhesive, then ZJ2(1) the contact disconnection, this moment, which road charging circuit all disconnected, stop charge in batteries, while JW5(2) closure is connected " overvoltage indication " lamp, and charge in batteries belongs to normal operative condition to crossing pressure point.Only provide the indication of " overvoltage " situation this moment, do not report to the police, do not cause system to quit work, when cell voltage dropped into 13V, resistance R 43 and the detected voltage of potentiometer W5 ended the G19 in the pulse generator 4, pulse generator produces a negative pulse and makes the upset of one of bistable circuit, the reduction of JW5 dead electricity, then JZ2 and ZJ2 reduction, the ZJ2(1) closing of contact, connect charging circuit, battery begins charging.If battery damage or equipment break down and can not battery be charged, then cell voltage will fall always, when dropping to 12.5V, the detected voltage of R55 and W6 ends the G24 in the pulse generator 5, the negative pulse that pulse generator sends makes another part action in the flip-flop circuit, the JW6 action, JW6(1) contact disconnects the power supply of start-up circuit part, system is quit work, while JW6(2) contacting " battery is under-voltage " indicator light and emergency alarm bell send the sound and light alarm signal, this moment or change battery or fix a breakdown after, equipment continues battery charge, when cell voltage was raised to 13.5V, the detected voltage of R64 and W7 made the G28 conducting in the pulse generator 6, and pulse generator sends negative pulse, the bistable circuit reduction, the JW6 reduction is connected the actuating section circuit again and is cut off the sound and light alarm signal, and system is in normal reserve operating state again.In order to prevent that cell voltage from causing the vibration of system in the minor fluctuations of crossing pressure point 14V and under-voltage some 12.5V, so design overvoltage and the under-voltage normal voltage that is returned to all have certain scope in the circuit, overvoltage is to be returned to just charging again of 13V from 14.5V, under-voltage is to be returned to the power supply that 13.5V just connects start-up circuit from 12.5V, when fixing a breakdown, K switch 3 should disconnect, otherwise the sound and light alarm signal will provide always.

In the generator automatic shutdown circuitry; when external power grid has a power failure; generator has started and during normal externally power supply; contactor CJ4 dead electricity is failure to actuate; CJ4(4) contact disconnects; if power system restoration power supply; CJ4(4 then) closure, G34 ends, and pulse generator 7 sends a negative pulse and makes the monostable circuit upset; the contact JW7(1 of relay J W7) closure; the generator outage signal is connected, and what generator autostop, at this moment monostable delay time must be greater than generators requires stopping signal turn-on time; otherwise generator will start once more automatically.

AN3 and AN2 are the buttons of opening and closing that is respectively applied for manual detection and detects automatically; the contact JZ3(1 of JZ3 relay) be attempted by the CJ4(1 of CJ4 in the starting box) on the contact; when pressing AN3; the JZ3 adhesive, JZ3(1) closure has simulated the situation that dispatch from foreign news agency has a power failure; the grid cut-off situation is consistent as described above with operation principle in the action of back; repeat no more, simultaneously JZ3(2) closure, system's power supply and self check indicator light are bright; after confirming system health; press AN2, simulate the situation of power system restoration power supply, CJ4(4) closure; then cause generator outage; (note: need be by just can decontroling more than 3 seconds, otherwise generator will start again automatically.If AN3 is connected with a certain timing circuit with AN2, regularly finish above-mentioned detection action, this does not give unnecessary details promptly to realize automatic measuring ability, in the time of need shutting down as the generator normal power supply (as coming off duty), only needs K2 dialled to position 2 and gets final product.

The present invention uses in part financial industry and Running-water Company, and the present invention of actual operating position proof has realized the described function of this paper the beginning part fully, and reliability height, warning working signal are obvious, and each system works situation comes into plain view, and is extremely easy to use.
