Description
Technical field
It is quickly calibrated more particularly, to a kind of calibration efficiency electric energy meter high the present invention relates to electric energy meter collimation technique field
Method.
Background technology
The existing calibration step of electric energy meter is as follows：
Checking table is switched to output Un, Ib, phase angle 1.0L- ＞ and waits stage body stabilization-＞ to receive error-＞ calculating corrections
Value-＞ write-in corrected values；
Checking table is switched to output Un, Ib, phase angle 0.5L- ＞ and waits stage body stabilization-＞ to receive error-＞ calculating corrections
Value-＞ write-in corrected values；
Checking table is switched to output Un, 5%Ib, phase angle 1.0L- ＞ and waits stage body stabilization-＞ to receive error-＞ calculating school
Corrected value is write on the occasion of-＞；
Using the electric energy meter of different chips, in timing except the points of required correction are different, the basic class of correcting mode
Seemingly.It is required for many stage body standard scales to make switching output when different points are corrected every time, and different producers is due to power source, mark
The difference of quasi- man of Watch Factory etc., is that the required wait stage body output stable time is also different in switching, even if same producer is same
Model stage body, the deviation of output stabilization time also occurs due to individual difference, in order to meet the difference of different manufacturers and stage body
Property, when time delay is waited, using most long delay, the stage body short for power source and standard scale switching time, loss in efficiency is serious.
The content of the invention
Goal of the invention of the invention is low in order to overcome the shortcomings of calibration efficiency of the prior art, calibrating efficiency, there is provided
One kind is quickly found out point of safes, saves the electric energy meter quickly calibrated side that standard source switching institute's stand-by period improves calibration efficiency
Method.
To achieve these goals, the present invention uses following technical scheme：
A kind of electric energy meter quick calibration method, including host computer, correction platform and electric energy meter, correction platform by serial line interface with
Host computer is connected, and correction platform is connected with electrical energy meter electricity；
Comprise the following steps：
Standard source is switched to (1-1) staff the gear of setting output voltage, electric current, phase angle；
Be stored with the standard value of voltage, electric current, phase angle on (1-2) host computer, host computer interval time T circulation reading standards
Voltage, electric current, the phase angle of source output；Standard source is while output voltage, electric current, phase angle are to electric energy meter；
(1-3) host computer calculates school according to the reading value of voltage, electric current, the standard value of phase angle and voltage, electric current and phase angle
The steadiness parameter a of table platform, as a≤W, correction platform receives the error of electric energy meter feedback；
(1-4) host computer is according to error calculation corrected value；
Corrected value is write electric energy meter by (1-5) host computer.
The present invention by each reading value and standard value to voltage, each reading value and standard value of electric current, phase angle
The stability of each reading value and standard value is analyzed, and realizes the judgement of stability to correction platform, when a≤W is met, then recognizes
For correction platform has stablized output, then receiving error carries out subsequent correction.
Preferably, host computer obtains the reading value of continuous voltage, electric current and phase angle, and by the way of first in first out
Rejecting is unsatisfactory for desired value, is required until continuous N number of value all meets, it is believed that the switching of stage body has been stablized；
For each reading value of voltage, electric current and phase angle, host computer utilizes formulaCalculate steady
Determine parameter a, when each reading value of voltage, electric current and phase angle is satisfied by a≤W, correction platform receives the error of electric energy meter feedback.
Preferably, the span of W is 0.05% to 0.1%.
Preferably, N >=10.
Preferably, the span of the T is 10us to 100ms.
The present invention improves the calibration efficiency of electric energy meter, is not in problems with：
1st, software can be with the switching time of self adaptation standard source, during compared to canned software design stability after correction platform is updated
Between the again more newly-designed problem that occurs no longer occur, saved exploitation, maintenance time and the efficiency of software
2nd, when stage body failure electric energy meter will not standard source output it is unstable when correction error, reduce due to mark
Incorrect problem is calibrated caused by the problem in quasi- source, it is to avoid unnecessary do over again and quality accident, improve electric energy meter
Outgoing
3rd, the method is applied to the electric energy meter correction error and verification error of all models.
4th, the method applies also for the metering device that other compare error checking using standard source.
Therefore, the present invention has the advantages that：Electric energy meter calibration, verification efficiency high, improve dispatching from the factory for electric energy meter
Quality, applicability is good.
