Description
Technical field
The invention belongs to intelligent electric meter application field, especially a kind of resident uses intelligent table status replacing options.
Background technology
At present, resident manages Main Basiss JJG596-2012 with intelligent meter《Electronic type AC energy meter》, code regulation
" 1 grade, 2 grades of active electric energy meters and 2 grades, 3 grades of reactive energy-meters, its re-testing periods are usually no more than 8 years ", resident is with intelligent meter
2 grades of active electric energy meters, thus the re-testing periods also should be 8 years.Tianjin started resident in 2009 and changed the outfit with intelligent meter work, pressed
Required according to examining and determine for 8 annual periods, the intelligent meter changed the outfit for 2009 need to be torn open back to be examined and determine again, but Examined point is run according to intelligent meter
Analysis, even if most of meter will be run 8 years, its component is still stable, metering defect problem does not occur, therefore can
To combine a kind of intelligent table status replacing options of related electric energy meter administrative skill research under existing concerned countries code framework, prolong
The long running stable intelligent meter re-testing periods.
The content of the invention
The present invention is overcome in place of the deficiencies in the prior art, is proposed a kind of design science, is easy to operation, reliable and stable, saving
The resident of the energy uses intelligent table status replacing options.
The present invention solves its technical problem and takes following technical scheme to realize：
A kind of resident uses intelligent table status replacing options, it is characterised in that：Specific implementation step is as follows：
(1) batch resident is inspected by random samples with intelligent meter every year, check batch Measurement reliability R；
(2) the R values measured according to previous step, calculate calibrating time interval, it is determined that extension or shortening re-testing periods interval,
If R >=90%, extend the calibrating time interval of the batch meter, if R≤90%, when shortening batch meter calibrating
Between be spaced,
(3) the qualification time interval of previous step is reached, is checked again, repeat step is (1), (2).
Moreover, (2) middle calibrating time interval is △ to step, computational methods are as follows：
△=a (or b) × I0
In formula：I0For time interval before adjustment, a is time interval increment coefficient, and b is time interval decrement factor, a=
0.2, b=0.3.
Advantages and positive effects of the present invention are：
1st, the present invention changes the outfit proposition under intelligent electric energy meter background for resident's high-volume, according to strict sampling observation technology, carries
One kind dynamic adjustment batch intelligent meter re-testing periods method gone out, this method can instruct resident to be changed the outfit with intelligent meter, make electric energy
Table operational management more science.
2nd, by taking Tianjin as an example, the work that changes the outfit of intelligent electric energy meter starts from 2009, since 2017 every year on average
Reaching the re-testing periods needs the tool of civilian intelligent meter about 700,000 of rotation, using every electric energy meter cost as 200 yuan of budgets, implements state
Tianjin is annual after rotation changes the outfit saving about 1.4 hundred million yuan of cost, and it is dirty that what is more important will also reduce by about 400 tons of whites every year
Contaminate thing discharge.Carry out civilian intelligent table status and change technical research and will targetedly implement meter and change the outfit work, can realize
Social resources are distributed rationally, are saved social construction cost, are realized human and environment harmonious and sustainable development.
Brief description of the drawings
Fig. 1 is Measurement reliability R (t) change schematic diagrams.
Embodiment
Below in conjunction with the accompanying drawings and the invention will be further described by specific embodiment, following examples are descriptive
, it is not limited, it is impossible to which protection scope of the present invention is limited with this.
A kind of resident uses intelligent table status replacing options, and specific implementation method is as follows：
According to JJF1139-2005《Verification Cycle in Measuring Instruments defining prinple and method》Extension resident is examined and determine with intelligent meter
In the cycle, require, batch resident is inspected by random samples with intelligent meter according to national regulation every year, check batch Measurement reliability R, root
According to R values, it is determined that extend or shorten re-testing periods interval,
Firstly, it is necessary to which clear and definite meter Measurement reliability target R, current standard assert reliability objectives R >=90%；
According to fixed ladder adjustment method Computing Principle, a certain batch resident intelligent meter is through after a period of time, its globality
It can suitably shorten the calibrating time interval of the batch meter not less than defined Measurement reliability target R；If its globality
Defined Measurement reliability target R is can exceed that, can be with the calibrating time interval of the proper extension batch meter.
Calibrating time interval is △, and computational methods are as follows：
△=a (or b) × I0
In formula：I0For time interval before adjustment, a is time interval increment coefficient, and b is time interval decrement factor, according to
We can take a=0.2, b=0.3 to experience,
For example, according to Tianjin electric energy meter sampling check for quality situation in 2016, it can be assumed that batch intelligent meter measurement in 2009
Reliability R >=90%, therefore calibrating time interval △=0.2 × 96 month ≈ 19 months can be extended, you can to extend operation 19
The moon is examined and determine again.
For another example assuming batch intelligent meter Measurement reliability R=85% in 2010, i.e., less than 90%, therefore shorten
Examine and determine time interval △=0.3 × 96 month ≈ 28 months, i.e., must just be examined and determine within 28 months in advance.
Although disclosing embodiments of the invention and accompanying drawing for the purpose of illustration, those skilled in the art can manage
Solution：Do not departing from the present invention and spirit and scope of the appended claims in, it is various replace, change and modifications all be it is possible,
Therefore, the scope of the present invention is not limited to embodiment and accompanying drawing disclosure of that.
