Background technology
Electric energy meter is under a kind of measurement rated voltage, the measurement instrument of the time-varying power over time integration passed through.
False actuation test is the accuracy test of electric energy meter.Relative method is generally used to carry out the accuracy test of electric energy meter, i.e.
Carried equal-wattage by power source to standard scale and tested table, Error Calculator receive standard scale and the output pulse of tested table
And calculate the relative error of tested table.Standard scale and the tested table the most nominally meter constant (arteries and veins often exported by 1kWh electric energy
Strokes per minute), think during measurement that the meter constant Ks of standard scale is actual value, and the meter constant Km of tested table is nominal value.Ks is remote
More than Km.Same electric energy meter Km is definite value, and therefore the biggest pulse frequency of bearing power is the highest, and the pulse spacing, Tp was the least.
Electric energy meter false actuation test method is: under conditions of the obstructed electric current of a making alive, in the time Tno-load of regulation,
Tested table output umber of pulse can not be more than 1.This requirement is equivalent to, and under the conditions of false actuation test, the tested table pulse spacing is more than Tno-
load.Owing to false actuation test power is zero, therefore theory T no-load is infinitely great, then needs to make Tno-load abundant during test
Greatly, usually more than 30min.
Along with carrying out of Guo Wang company low-voltage collecting meter reading engineering, change the outfit intelligent meter in high volume, and then causes intelligent meter to examine and determine work
Work amount increases severely.In order to complete verification task, the wilderness demand of reply intelligent meter, the present invention proposes rapid batch electric energy meter shunt running

Accompanying drawing explanation
Fig. 1 is electric energy meter accuracy test control principle drawing.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings and by specific embodiment, and following example are descriptive
, it not determinate, it is impossible to limit protection scope of the present invention with this.
A kind of rapid batch electric energy meter false actuation test method, it is therefore intended that the contracting of electric energy meter false actuation test calibrating time in batches
Subtracting, electric energy meter false actuation test scheme is in batches: first leads to big electric current and examines and determine the front time, in false actuation test, at certain value to shorten
Under voltage U, use larger current Im by time T1, realize time timing target by enumerator, reach target power consumption
E1；Afterwards under fixed value voltage U, power-off, whether calibrating occurs second pulse in certain time interval T 2, occurs then for not conforming to
Lattice, occur without be qualified.
Concretely comprise the following steps:
(1) by installing enumerator on standard scale；
(2) the calibrating of batch electric energy meter starting test, calculates under certain value voltage U, uses larger current Im to pass through the time
T1, when reaching target power consumption E1, obtains the umber of pulse about Ks1 that standard scale is exported in electric energy E1 value；
(3) batch electric energy meter false actuation test calibrating, under certain value voltage U, uses larger current Im by tested table and mark
Quasi-table；
(4) batch Basic Error of Energy Meter test calibrating, when rolling counters forward arrives umber of pulse Ks1, at certain value voltage
Under U, switch to test standard electric current IQ, until tested table sends pulse；
(5) calibrating terminates: carry out verification result judgement, it is judged that for "Yes" then off-test；Judged result is that "No" is then tested
Do not terminate, then repeat step (1) to step (4) until calibrating terminate.
Ultimate principle illustrates
The accuracy test of electric energy meter generally uses relative method to carry out the accuracy test of electric energy meter, i.e. by power source to mark
Quasi-table and tested table conveying equal-wattage, received standard scale and the output pulse of tested table by Error Calculator and calculate tested table
Relative error.Standard scale and tested table the most nominally meter constant (umber of pulse often exported by 1kWh electric energy), during measurement
Think that the meter constant Ks of standard scale is actual value, and the meter constant Km of tested table is nominal value.Ks is much larger than Km.Same class
Electric energy meter Km is of substantially equal for type, and therefore the biggest pulse frequency of bearing power is the highest, and interpulse period is the least.
The time occurred due to first pulse of tested table has randomness, when same batch tested table quantity is more than 30
Time, the note waiting time is Tw.Then theory analysis shows, the Tw probability more than 0.9 is up to 0.96.The most general Tw ＞ 0.9.
The electric energy consumed between two adjacent pulses of tested table is a definite value, is designated as E.Imagine under certain value voltage U,
Use larger current Im by time T1, reach target power consumption E1；Afterwards under fixed value voltage U, switch to test standard
Electric current IQ, by time T2, reaches remainder power consumption E2.And remember under fixed value voltage U, reach electric energy E value, required logical
The extra pulse separation standard time is TQ.
Then there are E=E1+E2=U Im T1+U IQ T2, TP=T1+T2.
Wherein, E1 and Im is independent variable, and can obtain T1, E2 and IQ by the two value is independent variable, by the two value
T2 can be obtained.And then available interpulse period.As Im ＞ IQ, then there is TP ＜ TQ, thus reach to reduce pulse spacing mark
The target of TQ between Zhun Shi.And then by controlling IQ value, T1 ＜ TW can be realized.
Such as make Im=20IQ, E1=0.9E, E2=0.1E.
Then can pass through E1=U Im T1, E=E1+E2=U Im T1+U IQ T2 and TP=T1+T2,
Calculate to obtain T1 ≈ 0.45 T2, ≈ 1.45*T2 < < TQ ≈ 10*T2, T1 ＜ TW.
Owing to Ks was much smaller than much larger than Km, the then pulse spacing understanding standard scale.By installing enumerator on standard scale,
Obtain the umber of pulse about Ks1 that standard scale is exported in electric energy E1 value.By using larger current by forward part energy, work as meter
When pulse approximate number Ks1 remembered by number device, switch tested table and pass through electric current, reach to count purpose.
Although disclosing embodiments of the invention and accompanying drawing for the purpose of illustration, but those skilled in the art can managing
Solving: without departing from the spirit and scope of the present invention, various replacements, to change and modifications be all possible, therefore, and the model of the present invention
Enclose and be not limited to embodiment and accompanying drawing disclosure of that.
