The automatic energy-saving control device of the axial fan of the main transformer has stable running condition and reliable action. The utility model saves a large number of electric energy for a transformer substation and can reduce the noise pollution obviously. For the transformer substation close to a residential area, the utility model has a very important meaning.
Description
Technical field
The utility model relates to the main transformer axial fan, relates in particular to a kind of main transformer axial fan automatic energy saving control gear.
Background technique
In the prior art; electric substation is through boisterous tests such as regular meeting's experience high temperature and thunders and lightnings; the operation conditions instability; the temperature of main transformer is influenced by ambient temperature and power load size generally; along with variation of temperature; the axial fan of main transformer can not start or stop automatically; then caused the electric energy loss of main transformer big; on the other hand; main transformer is about 50 decibels at the operation noise under the situation of not opening axial fan, and after opening axial fan, noise is increased to about 60 decibels; will cause bigger influence to surrounding enviroment, influence resident's living environment.
Summary of the invention
The purpose of this utility model is to overcome the defective of prior art, and a kind of main transformer axial fan automatic energy saving control gear is provided, and this control gear operation conditions is stable, reliable in action.For electric substation has saved a large amount of electric energy, reduced the noise of electric substation, obtained good economic benefit and social benefit.
The technological scheme that realizes above-mentioned purpose is: a kind of main transformer axial fan automatic energy saving control gear, comprise the axial fan in the main transformer, wherein, also comprise the diverter switch that automatic Control Shaft flow fan startup and the temperature controller that stops, the button and that starts and stop by time Control Shaft flow fan startup and the micro computer timed unit that stops, manual Control Shaft flow fan are used to switch, wherein:
Described temperature controller links to each other with an alarm indicator lamp with a temperature transducer, described temperature transducer detects the upper strata oil temperature of main transformer, and numerical value is transferred to described temperature controller, described temperature controller output control signal give described axial fan with the Control Shaft flow fan startup and stop, and output high temperature alarm signal is given described alarm indicator lamp;
Described micro computer timed unit output time control signal gives described axial fan with time opening and closing axle flow fan;
Described button links to each other with the startup of manual Control Shaft flow fan and stops with described axial fan;
Described diverter switch links to each other so that the three is switched with the output terminal of described micro computer timed unit, temperature transducer, button respectively.
Above-mentioned main transformer axial fan automatic energy saving control gear, wherein, be connected with one first auxiliary reclay between described temperature controller and the described axial fan, be connected with one second auxiliary reclay between described micro computer timed unit and the described axial fan.
The beneficial effects of the utility model are: the utility model can start or stop the running of fan automatically according to the temperature of main transformer.During meet the kurtosis summer summer, after tested, original electric substation's 160 axial fans that put into operation altogether, the power of every axial fan is 2.2 kilowatts.If use the automatic energy saving control gear, every main transformer axial fan can reduce 10 hours running time to estimate every day, 160 axial fans can reduce 1600 hours running time every day, save power 3520 kilowatt hours, calculate by meeting 100 days kurtosis summers, altogether can save power 35.2 ten thousand kilowatt hours, the energy-saving effect highly significant; On the other hand, after at 10 in general evening, the temperature of main transformer will descend, use automatic controller after, axial fan shuts down automatically, can obviously reduce noise pollution, this is for the electric substation near the residential belt, tool has very important significance.
Description of drawings
Fig. 1 is the structural representation of main transformer axial fan automatic energy saving control gear of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
See also Fig. 1, there is shown a kind of main transformer axial fan automatic energy saving control gear of the present utility model, comprise the axial fan 1 in the main transformer (not shown), also comprise the diverter switch 5 that automatic Control Shaft flow fan 1 startup and the temperature controller 2 that stops, the button 4 and that starts and stop by 1 startup of time Control Shaft flow fan and the micro computer timed unit 3 that stops, manual Control Shaft flow fan 1 are used to switch, wherein:
Micro computer timed unit 3 output time control signals give axial fan 1 with time opening and closing axle flow fan 1, micro computer timed unit 3 and axial fan 1 between be connected with one second auxiliary reclay 9.
Diverter switch 5 links to each other so that the three is switched with the output terminal of micro computer timed unit 3, temperature transducer 2, button 4 respectively.
Working principle of the present utility model: after main transformer upper strata oil temperature surpassed the startup value of setting, control gear started axial fan 1 automatically.After main transformer upper strata oil temperature drops to the close value of setting, automatic closing axle flow fan 1.Axial fan 1 starts when the main transformer temperature surpasses 70 ℃ automatically, reduces the intensification amplitude, reaches balance during to 75 ℃, can guarantee that the insulation of main transformer is unlikely to the too high insulation ag(e)ing phenomenon that causes of temperature, the stable operation of main transformer when having guaranteed higher load again simultaneously; Axial fan 1 is closed when the main transformer temperature is lower than 68 ℃ automatically, has avoided axial fan 1 because of the temperature definite value too small frequent starting to be set, simultaneously again at the maximum energy-saving effect of guaranteeing under the transformer safe operation situation that reaches.
Below embodiment has been described in detail the utility model in conjunction with the accompanying drawings, and those skilled in the art can make the many variations example to the utility model according to the above description.Thereby some details among the embodiment should not constitute qualification of the present utility model, and the scope that the utility model will define with appended claims is as protection domain of the present utility model.
