Description
Technical field
The utility model relates to technical field of generators, more particularly to the improvement to stand-by generator control system.
Background technique
Now, many local not shorts of electricity, some single important events important equipments need multiple power supplies to ensure, and conventional
Backup power source group is not worked in the case that alternating current has electricity, and backup power source starts power transmission after mains failure.It is continuous for a long time in alternating current
In the case where electricity, backup power source is not to be switched on or only under no-load running, such case is very unfavorable to generating set.
Utility model content
The utility model in view of the above problems, provide whether one kind can have a power failure regardless of alternating current can be in real time to standby electricity
Source stay in the high power intelligent electricity generation system based on same period load control of operation test.
The technical solution of the utility model is：Including test device, the test device is placed in utility grid and standby electricity
Between source, it is electrically connected load in the utility grid, chopper switch K is equipped between the load and the utility grid, it is described
Test device is separately connected the utility grid and backup power source；
The test device includes Switching Power Supply, relay, coil one and coil two, and the input terminal of the Switching Power Supply connects
It connects on the utility grids, the input terminal of the output end connection relay of the Switching Power Supply, the output end connection of the relay
Coil one, the coil two are connect with the backup power source；
It is equipped with switch KM2 between the coil two and the backup power source, is equipped with and opens between the backup power source and load
Close KM1 and switch KM3, the one control switch KM1 of coil and switch KM2, the two control switch KM3 of coil.
It is separately connected between the backup power source and the load by independent cable one and cable two, the cable one
It is equipped with switch KM3, the cable two is equipped with switch KM1.
The relay is the time relay of model JS-11A/11, and the Switching Power Supply is model S-100-24 switch
Power supply.
When the utility model carries out band load test under the non-power failure of alternating current, it is first shut off chopper switch K and to load
Circuit power loss, automatic switching to backup power source is powered at this time, but since utility grid does not have a power failure, Switching Power Supply is still
Work, relay power start timing, coil one also it is electric, switch KM1 closure when coil one must be electric, KM2 is in coil one
Disconnection when obtaining electric carries out so that forming access by switch KM1 between backup power source and load with load test, relay meter
When the time arrive after disconnect, coil one disconnects from Switching Power Supply, one power loss of coil, and switch KM1 disconnection, switch KM2 is closed, line
Circle two it is electric, backup power source and load between by KM3 formation access, powering load, complete at this time entire backup power source and
Chopper switch K, automatic switching to utility grid powering load are closed in the detection of interlock circuit.It can test at any time so standby
With the load capacity of power supply, avoiding backup power source from not having to cause for a long time, backup power source load capacity is degenerated and backup power source is being tested
In the process it is run with load, the true load capacity of backup power source in use can be tested, extend backup power source
Service life.
Detailed description of the invention
Fig. 1 is the utility model structure diagram,
Fig. 2 is the utility model electrical schematic diagram.
Specific embodiment
The utility model is as shown in Figs. 1-2, including test device, and the test device is placed in utility grid and backup power source
Between, it is electrically connected load in the utility grid, chopper switch K, the survey are equipped between the load and the utility grid
Trial assembly, which is set, is separately connected the utility grid and backup power source；It is realized when utility grid does not power off to standby using test device
It is tested with the run with load of power supply, that is need to cut off the disconnecting link between load and utility grid in test device work
Switch K causes load circuit power failure phenomenon, is carried using backup power source band, can be started at this time when utility grid does not have a power failure
Backup power source carries out band and carries test, and the band for capableing of real-time perfoming backup power source carries test, and backup power source is avoided to shut down because of long-time
The problem of bring backup power source damages.
The test device includes Switching Power Supply, relay, coil one and coil two, and the input terminal of the Switching Power Supply connects
It connects on the utility grids, the input terminal of the output end connection relay of the Switching Power Supply, the output end connection of the relay
Coil one, the coil two are connect with the backup power source；
It is equipped with switch KM2 between the coil two and the backup power source, is equipped with and opens between the backup power source and load
Close KM1 and switch KM3, the one control switch KM1 of coil and switch KM2, the two control switch KM3 of coil.
It is separately connected between the backup power source and the load by independent cable one and cable two, the cable one
It is equipped with switch KM3, the cable two is equipped with switch KM1；When carrying out band load test under the non-power failure of alternating current, close first
It closing chopper switch K and makes load circuit power loss, automatic switching to backup power source is powered at this time, but since utility grid is not stopped
Electricity, therefore Switching Power Supply still works, relay power start timing, coil one also it is electric, switch KM1 coil one it is electric when
It is closed, KM2 is disconnected when coil one obtains electric, so that forming access by switch KM1 between backup power source and load, is carried out
Band carries test, and relay timing time disconnects after arriving, and coil one disconnects from Switching Power Supply, one power loss of coil, and switch KM1 is disconnected
It opens, switch KM2 closure, coil two must be electric, forms access by KM3 between backup power source and load, and powering load is complete at this time
At the detection of entire backup power source and interlock circuit, chopper switch K, automatic switching to utility grid powering load are closed.This
Sample can test the load capacity of backup power source at any time, and backup power source is avoided not have to that backup power source load capacity is caused to be degenerated for a long time
And backup power source is run with load during the test, can test the true band of backup power source in use and carry energy
Power extends the service life of backup power source.
When utility grid has a power failure, Switching Power Supply stops working, one power loss of coil, and switch KM2 is closed, and coil two is from spare
Obtained at power supply it is electric so that switch KM3 obtain it is electric, load by closure KM3 and backup power source between form access, utilize standby electricity
Source power supply is until city power recovery powers.
The relay is the time relay of model JS-11A/11, and the Switching Power Supply is model S-100-24 switch
Power supply.
