The operation principle of this embodiment: during grid power blackout, the first K switch 1 when automatic, the 4th time relay JS4-1 and the normally closed point of the first A.C. contactor CJ1-2, CJ2-2.Connect generator starter and make generator starting, after starting, generator generation voltage makes the second A.C. contactor CJ2 adhesive that power supply is outputted to user's power supply.If when engine has fault or generator not to go out electricity, the 4th time relay JS4 closes starter in starting setup times.If engine start is normal but generator does not have electricity to export time, at this moment the 5th time relay JS5 just starts to carry out JS5-1 adhesive in timing to setting-up time to the race of engine and is closed down by engine.At this moment relay J S6 timing simultaneously will shut down dump in shutdown setting-up time.When so just preventing generating set from not having electricity to export, and engine continues no-load running.
During electrical network incoming call; very first time relay J S1 starts JS1-1 adhesive JS1-2 in timing to setting-up time and is separated; second A.C. contactor CJ2 contact separation cuts off generator power supply; CJ1 adhesive; connect electric network source, simultaneously the first relay J 1 also start of adhesive J1-1 separation cut JS4 power-off generator and halt circuit.At this moment JS2-1 is shut down in the no-load running time before the second time relay JS2 starts timing to setting generator shutdown; JS2-2 adhesive, the 3rd time relay JS3 starts timing, JS3-2 within the setting unused time; be separated, cut off generator and close electromechanical source and relay J S4 power supply.So just electric network source can be realized and generator power supply is automatically changed.
More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection range is defined by appending claims and equivalent thereof.
