Specific embodiment
The explanation of following embodiment is refer to the attached drawing, can be in order to the specific embodiment implemented in order to the example present invention.
Refer to shown in Fig. 1, the embodiment of the present invention one provides a kind of electric energy metering error exhibiting device, comprising:
Electric power meter installation plate and power module；
It is arranged on the standard electric energy metrical display module on electric power meter installation plate, for the electric energy that power module is inputted
Measured and shown；
The error being arranged on electric power meter installation plate produces metering display module, for the feelings disturbed in undisturbed source
Respectively the electric energy of power module input is measured under condition and in the case of the source interference that is interfered and shown.
Specifically, electric power meter installation plate is square panel, is embedded with thereon for fixedly mounting standard electric energy metrical
Display module and error produce the buckle measuring display module and associated tracks.In this enforcement, standard electric energy metrical shows mould
Block and error produce metering display module and are the electric energy meter showing with real time measure power.
Power module may be selected 220v and 380v as electric energy metrical input source.Power module inputs electric flux, standard electric
Display module can be measured with error generation metering display module, the electric flux of input is measured and shows.Under normal circumstances
(being not affected by interference source interference), because standard electric energy metrical display module and error produce metering display module to same electric energy
Amount is measured, and the result therefore showing is consistent；When metering display module enforcement interference is produced using interference source to error,
Standard electric energy metrical display module is because being not affected by interference still normal presentation, and error produces the displaying result of metering display module
Difference can be produced, because standard electric energy metrical display module and error produce metering display module and be arranged at electric power meter
On installation plate, therefore, this species diversity can intuitively show student, so that student observes the concrete feelings that error in dipping produces
Condition.
In the present embodiment, interference source includes strong magnetic disturbance source and High-frequency Interference source, is done by strong magnetic disturbance and high frequency respectively
Disturb to make error produce metering display module generation error in dipping and show.
Strong magnetic disturbance source includes producing strong magnet and the electric magnet of big intensity magnetic field, and big intensity magnetic field produces meter to error
Amount display module is implemented interference and is allowed to produce error in dipping, and the error features that it produces are error in dippings and the intensity in magnetic field and position
It is equipped with pass, the electric energy power that error produces shown by metering display module can reduce and remain with certain reading.
High-frequency Interference source includes producing the equipment of electromagnetic field of high frequency, and electromagnetic field of high frequency mushing error produces metering and shows mould
The normal work of electronic component in block and produce error in dipping, this interference can make error produce metering display module enter crash
State, thus cannot normally measure, the form of expression produces metering display module flashlight for error and does not flash, display screen blank screen,
Therefore error produces metering display module display metering power is 0.
Corresponding to a kind of electric energy metering error exhibiting device of the embodiment of the present invention one, the embodiment of the present invention two provides a kind of electricity
Energy error in dipping methods of exhibiting, as shown in Figure 2, comprising:

Block is measured to this electric flux respectively and is shown；
Step s3, individually produces metering display module and implements interference, produced by standard electric energy metrical display module and error to error
Livelihood amount display module is measured to this electric flux respectively and is shown.
(it is not affected by interference source interference) under normal circumstances, because standard electric energy metrical display module produces meter with error
Amount display module measures to same electric flux, and the result therefore showing is consistent；Count when being produced to error using interference source
When amount display module implements interference, standard electric energy metrical display module is because being not affected by interference still normal presentation, and error produces
The displaying result of metering display module can produce difference, because standard electric energy metrical display module and error produce metering and show mould
Block is arranged on electric power meter installation plate, and therefore, this species diversity intuitively can show student, so that student observes
The concrete condition producing to error in dipping.
In step s3, the interference of enforcement includes strong magnetic disturbance and High-frequency Interference, and big intensity magnetic field produces metering exhibition to error
Show that module is implemented interference and is allowed to produce error in dipping, the error features that it produces are that error in dipping is had with position with the intensity in magnetic field
Close, the electric energy power that error produces shown by metering display module can reduce and remain with certain reading.Electromagnetic field of high frequency is to by mistake
Difference produces the normal work of electronic component in metering display module producing error in dipping, and this interference can make error produce metering
Display module enters deadlock state, thus cannot normally measure, the form of expression produces metering display module flashlight not for error
Flicker, it is 0 that display screen blank screen, therefore error produce metering display module display metering power.
By described above, implement the embodiment of the present invention, have the advantages that
Apply to lead to the standard electric energy metrical display module before and after the interference of electric power meter generation error by contrasting respectively
Produce the power of the electric flux that metering display module is measured with error, and displaying disturbance directly perceived produces in error and shows
The difference that module is embodied, recognizes disturbance measure to the form of expression of metering device not with allowing student's intuitive and convenient
With thus improving the level of skill of student.
Above disclosed be only present pre-ferred embodiments, certainly the right model of the present invention can not be limited with this
Enclose, the equivalent variations therefore made according to the claims in the present invention, still belong to the scope that the present invention is covered.
