Abstract
The invention provides an automatic generator controller and a control method of the automatic generator controller. The automatic generator controller comprises a generator start control part, a generator output control part and a generator shutdown control part. The automatic generator controller is compact in structure and has complete functions. A relay is directly connected with a mains supply and can quickly judge the make-and-break state of the mains supply and automatically start a generator for power generation in time. Meanwhile, as a certain delay is set, the situation that the generator is started under the flash-break condition of the mains supply, so that waste is caused is avoided. Besides, after the automatic generator controller is adopted, base station maintenance personnel do not need to manually and repeatedly shut down an oil engine, and therefore manpower and material resources are saved.

Accompanying drawing explanation
Fig. 1 is generator full automatic controller structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in detail.
Paper generator full automatic controller.
According to feature difference, generator full automatic controller is divided into three parts, and generator starts control section; Generator output control part; Generator shutdown control section.
Generator starts control section:
Comprise three relays of three-phase and four-line electrical connection, the output of described three relays connects fuel tank switch, the 4th relay, described fuel tank switch, the 4th relay are connected with very first time relay input respectively again, two outputs of described very first time relay are connected to a D.C. contactor input by second time relay, the 3rd time relay respectively, described D.C. contactor output is connected with the motor of generator, and the output of described generator is connected with the 4th relay input.
Preferably, between described fuel tank switch and the 5th time relay input, be provided with the first hand switch.
Principle: three relays of three-phase and four-line electricity access, produce signal.The normally-closed contact closure of three relays when the equal power-off of three-phase, the 4th relay conducting.In the time that fuel tank has oil, fuel tank switch sends signal to very first time relay, very first time relay conducting; In the time that in fuel tank, nothing is oily, not transmitted signal, very first time relay keeps cutting out.The first manual control switch controls generator operating state, and in the time that it disconnects, generator actuating section stops.In the time of generator generating output voltage, the 4th relay disconnects, and generator starts to be ended.
Cause that for fear of civil power flash generator starts, very first time relay provides a time delay (being generally 20 seconds, adjustable), and when civil power is in setting-up time when flash, it can conducting, and generator starts control section and do not work.Stop power supply and exceed after setting-up time when civil power, very first time relay conducting, and the time relay of one-level sends enabling signal backward.(time delay of second time relay is generally set as 5 seconds to the time delay of second time relay, the 3rd time relay, the time delay of the 3rd time relay is generally set as 12 seconds, all adjustable) the rear starting duration signal controlling electric organ motor starting that produces a setting of addition.
Generator output control part:
Comprise the ac delayer connecting in turn, A.C. contactor; Described ac delayer input connects generator output end, and A.C. contactor is connected with load.
Principle: the output voltage 220V of generator divides two-way, the 4th relay of actuating section is controlled on a road, makes to start loop and disconnects, and guarantees that actuating section reliably stops; The ac delayer (being generally 5 minutes, adjustable) of generator output control part is controlled on another road, guarantees that generator has individual warm.Warm-up time is adjustable, and warm-up time in winter is long, and warm-up time in summer is shorter.After A.C. contactor conducting, generating voltage is passed to load.
Generator shutdown control section:
Comprise electromagnetically operated valve, two inputs of described electromagnetically operated valve are connected with three relays of same three-phase and four-line electrical connection, and described electromagnetically operated valve output is connected with generator oil circuit.
Preferably, between one of them input that the output of three relays and electromagnetically operated valve connect, be provided with the second manual control switch.
Principle: be connected to three relays by civil power three-phase and four-line, produce signal source.As long as three-phase will produce off signal while having one to send a telegram here mutually.Its three relays share with three relays that start control section, use respectively one group of contact.When the second manual control switch disconnects, oil machine is in off-mode.The oil circuit of solenoid control generator.When after incoming call, the normally closed contact of three relays disconnects, and electromagnetically operated valve loses voltage and valve closing is truncated the fuel feeding of its generator, and generator stops.
Again the control method of above-mentioned controller is described below:
Described control method comprises the following steps:
Step 1: judge whether three-phase and four-line electricity has a power failure, if arbitrary one mutually incoming call, carry out step 2, if three-phase all stops, carry out step 3;
Step 2: the normally-closed contact of three relays disconnects, electromagnetically operated valve valve closing, generator quits work;
Step 3: the normally-closed contact closure of three relays, the 4th relay conducting; When fuel tank has oil, fuel tank switch, to very first time relay transmitted signal, carry out step 4, and fuel tank does not have transmitted signal not of oil, the very first time not conducting of relay;
Step 4: if power-off time is no more than the setting time of delay of very first time relay, the very first time not conducting of relay; If exceeded, carry out step 5;
Step 5: very first time relay conducting;
Step 6: second time relay, the equal conducting of the 3rd time relay, both time delays are added, delay time signal input direct-current contactor;
Step 7: generator motor running, output voltage;
Step 8: the output voltage of generator is transported to the 4th relay, the 4th no longer conducting of relay, generator starts control section and quits work, and meanwhile, the output voltage of generator is input to ac delayer;
Step 9: ac delayer conducting;
Step 10: generator preheating, be that ac delayer sets time of delay warm-up time;
Step 11: A.C. contactor conducting;
Step 12: generator output voltage is to load;
Step 13: return to step 1.
Advantage of the present invention is:
Compact conformation of the present invention, complete function, relay is directly electrically connected with three-phase and four-line, can judge fast the break-make of civil power, and starter-generator generates electricity automatically in time., start the civil power flash in the situation that for fear of generator meanwhile, cause waste, the present invention sets certain time delay by setting very first time relay, has guaranteed that generator does not start in flash situation.
The benefit that the present invention arranges two manual control switches is: in the time that the first manual control switch, the second manual control switch close, generator is in Automatic Control state; In the time that the first manual control switch, the second manual control switch disconnect, generator, in halted state, is power-off rehearsal for oil machine maintenance or people; In the time that the first manual control switch disconnects, the second manual control switch closes, generator manually starts and automatic shutdown state in partial-automatic control state.In the time that oil start part has obstacle with this kind of state.
After adopting the present invention, base station maintenance personal does not need to carry out back and forth manual-lock oil machine again, uses manpower and material resources sparingly.
