Abstract
The utility model relates to a power supply technical field, concretely relates to generating set schizolysis protection system side by side in same term, including the controller with install the generating set on power -generating cars, still including install on generating set with controller electric connection's load cell, tachometric relay, oil pressure gauge, water temperature sensor, level sensor and power direction relay system, the battery voltage relay is being connected to the last battery that is equipped with of generating set, battery, battery voltage relay and controller electric connection, the utility model discloses the performance is higher, can carry out effectual protection to the generating set after side by side, in case the unit break down, just can automatic breaking, with electric wire netting parallel off, auto -stop, the effectual fail safe nature who has ensured the power supply makes the production life obtain the sound assurance.
Description
Technical field
The utility model relates to power supply technique field, is specifically related to a kind of generating set synchronization paralleling cracking protection system.
Background technology
Generating set is very important operation side by side; non-synchronous can produce very large impulse current side by side; make generator spiral modification, tear, insulation damages; jeopardize the safety of generating set self; even cause engine shaft to rupture, therefore require generating set synchronous device and control, protective device reliably complete.
Generating set side by side, once break down, will be given power supply, produce and bring great loss, also not have a kind of protection system now, can provide good protection to generator unit.
Utility model content
In order to the deficiency in solving the problems of the technologies described above, the purpose of this utility model is: provide a kind of generator synchronous cracking protection system arranged side by side, can play good protective effect to generator.
The technical scheme that the utility model adopts for its technical problem of solution is:
Described generator synchronous cracking protection system arranged side by side; comprise controller and be arranged on the generating set on generator car; also comprise the load cell, tachometric relay, oil pressure gauge, cooling-water temperature sensor, level sensor and the power direction relay system that are arranged on and generating set is electrically connected with controller; generating set is provided with storage battery; storage battery is connected to storage battery potential relay, and described storage battery potential relay and controller are electrically connected.
Further preferably, generating set is equipped with alarm, and alarm is connected to scram button, and scram button is connected to generating set.
Further preferably, also comprise display and control panel, can related data be shown, operate.
Further preferably, alarm is provided with alarm lamp, can play good alarm function.
Compared with prior art, the utility model has following beneficial effect:
The utility model performance is higher, can to side by side after generating set effectively protect, once unit breaks down; just can breaking automatically, with electrical network parallel off, autostop; the effective security reliability ensureing power supply, makes productive life obtain sound assurance.
Accompanying drawing explanation
Fig. 1 the utility model structured flowchart.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
As shown in Figure 1; generator synchronous cracking protection system arranged side by side described in the utility model; comprise controller and be arranged on the generating set on generator car; also comprise the load cell, tachometric relay, oil pressure gauge, cooling-water temperature sensor, level sensor and the power direction relay system that are arranged on and generating set is electrically connected with controller; generating set is provided with storage battery; storage battery is connected to storage battery potential relay, and described storage battery potential relay and controller are electrically connected.
1. overload fault: if when generating set runs, its power output is greater than 10% of rated power, generating set surpasses power just easily makes unit damage; In-site installation load cell, when serious excess load autostop.
2. exceed the speed limit fault: if when generating set exceedes rated speed operation, and generating frequency can be caused different from mains frequency; Therefore devise tachometric relay, when generator operation rotating speed is greater than 2 times of rated speed, regard it as fault, autostop.
3. oil pressure faults: whether the lubricating system of generating set is normally reflected by its oil pressure, oil pressure is abnormal can be considered that unit is in abnormal operational conditions, by relay autostop time serious.
4. water temperature, water level fault: the recirculated water of generator is used for unit cooling, when anhydrous in unit, few water or water temperature over-high, illustrates that cooling system is abnormal, unit can be made to damage; Cooling-water temperature sensor, level sensor are now installed, the autostop when its abnormal condition.
5. accumulator failure: storage battery is used for self excitation of Stator, and the quality of excitation system directly affects the running quality of generating set, therefore devises storage battery potential relay, the autostop when its fault.
6. power direction fault: export electric energy to electrical network when generating set normally runs, time improper, electrical network provides power supply to generator, and now generator just becomes motor and consumes electric energy.Therefore devise power direction relay system, make generator can only provide power supply to electrical network, once oppositely just with electrical network parallel off, autostop.
7. emergency stop (apparatus): when generating set in case of emergency, can by scram button make generating set moment and electrical network parallel off, stop unit operation.
Claims (4)
