Embodiment
Specific embodiment of the present utility model is described further below in conjunction with the accompanying drawings.Herein it should be noted that
It is used to help understand the utility model for the explanation of these embodiments, but does not form to restriction of the present utility model.This
Outside, as long as technical characteristic involved in each embodiment of the utility model disclosed below does not form conflict each other
Can is mutually combined.
As Figure 1-3, a kind of power supply of lampblack absorber cleaning equipment, after city is electrically accessed power supply, by rectification circuit, i.e.,
The full bridge rectifier of diode D1, D2, D3, D4 composition, then by after High frequency filter C1 again after transformer drops to 5V
Single-chip microcomputer is powered, in the present embodiment, the single single-chip microcomputer using STC15W series.
In order to realize the function of automatic adjusument, the power supply is provided with the function of current detecting, passes through rectification circuit in civil power
To isolate after rectification by magnet ring, then isolated after filtering by optocoupler Z5 after circuit filtering again, last signal is transferred to single-chip microcomputer,
When continuous high voltage arc is occurring in power supply in load, optocoupler Z5 conductings, single-chip microcomputer receives signal, then adjusted automatically
Section.
The output end of single-chip microcomputer is connected with drive circuit i.e. frequency modulation circuit, and the chip of the circuit uses tl494,
Electric signal is powered after frequency modulation(PFM) to after transformer boost for lampblack absorber cleaning equipment.
For the protection to whole power supply in place, open-phase protection module is additionally provided between rectification module and single-chip microcomputer, is led to
Optocoupler Z3 break-make is crossed to protect whole circuit.
Likewise, the power supply also includes temperature detecting module, for detecting the temperature in whole power supply, temperature detecting module
Including temperature sensor, the output end of temperature sensor and the input of single-chip microcomputer are electrically connected.
In addition, the power supply also includes overvoltage protective module, overvoltage protective module includes two optocouplers Z1, Z2, wherein optocoupler
Z1 is in parallel with optocoupler Z2 in circuit, and two optocouplers Z1, Z2 output end and the input of single-chip microcomputer connect.
The power supply has following function：
1st, sparking automatic protection functions are automatically adjusted：
Power source internal band automatic adjusument function, when is there is continuous high voltage arc in power supply in load, output voltage meeting
Automatic to reduce a numerical value, if sparking degree is reduced or disappeared, power supply can rise automatically after working 3 seconds returns to setting voltage
Value, but if occurring the sparking that takes place frequently again, output voltage can reduce again, until in continuous reduction work minimum, electric field
Still frequently sparking, power supply can close output, while red alarm indicator lamp flashes, then power supply can restart again after 8 seconds.
2nd, short-circuit protection function：
