Background technology
Electricity stealing generation often brings about great losses to power supply enterprise and country.Common stealing mode passes through change
The electric current of electric energy meter is accessed, voltage changes structure and mode of connection of meter etc..With the development of technology, the means of stealing and
Technical merit is also constantly being promoted, and shows as high-technicalization, and concealment is stronger, and opposing electricity-stealing, it is increasing to investigate and prosecute work difficulty.Surreptitiously
Electricity is often modified the wiring of electric energy meter outside or inside circuit, reaches few quantity calculation, underpays the electricity charge or do not pay the electricity charge
Purpose.Under conventional situation, line loss is abnormal, and electricity is lost, and often can just be embodied when settling accounts at the end of month.Traditional is thief-proof
Electric hand section relatively falls behind, and after electricity stealing occurs, cannot find and investigates and prosecutes in first time, often held in electricity stealing
It is just found after having continued a period of time, as technology develops, many electricity stealings are high in technological content, and behavior is very hidden, mostly
Situation cannot find that effect of opposing electricity-stealing is not fairly obvious in time.Although punishment is very big, still there are fish that has escape the net, crime point
There are idea of leaving things to chance, electricity stealings to happen occasionally for son.
Wrong wiring of electric energy meter can cause measuring error, more notes or few quantity calculation, carry out remedying electricity afterwards and often cause
User is discontented, it is believed that the responsibility of problem goes out in one side of electric company, and electric company is easy to unnecessary trouble oneself is added
Resentment is generated, generally will not actively be coordinated, and then generates unnecessary economic dispute, good service is caused to be complained, to confession
The economic benefit and social image of electric enterprise cause immeasurable loss.In terms of practical experience, using traditional means, electric energy meter
False wiring is often after electric energy meter charges actual motion for a period of time, and after forming certain wrong electricity, being likely to can quilt
It was found that coming out.

The method of the present invention principle is as follows:Under normal operation, all electrical equipments of each user will not be same
Moment opens and is simultaneously closed off same simultaneously(Have a power failure, except shut-down).Each electrical equipment puts into operation, will necessarily be
In the total electricity consumption trend of the user, total active power, reactive power, power factor, load impedance, harmonic component etc. are shown as
There is the variation of step evolution in power consumption parameter monomer or its operation combination.The variable quantity is caused by the equipment of just live line work.
When the variable quantity of active power, reactive power, load impedance, harmonic component etc. is substantially equal to single such equipment isolated operation
Magnitude.
The active power and reactive power numerical value and its relative ratio consumed when the operation of each electrical equipment(Power because
Number)And load impedance and the harmonic component of generation all follow certain rule, numerical value is all in certain reasonable interval range
Interior, such as performance is close to some percentage of rated power, and minimum operation power is more than some threshold value(It can be according to reality to threshold value
Border situation is set).The power factor of inductive load impedance has significant difference etc. with the power factor of capacitive load impedance.Electricity
When energy table correctly measures, the electric parameter measured defers to above-mentioned rule.Generally than more covert, electricity filching person will not be complete for electricity stealing
Turn-off current circuit can also make electric energy meter ins and outs continue to change.When electricity stealing occurs, although electricity stealing is generally compared
More covert, electricity filching person will not be fully disconnected current loop, also electric energy meter ins and outs can be made to continue to change.Before no longer following
All or part of rule is stated, off-note, such as main parameters are presented:Proportional decline such as active power, reactive power etc..Example
Such as, the electric light of a 15W, when it is lighted, active power value added that the electric energy meter that normally measures measurespFor 15W.If hair
Raw electricity stealing, then the active power changing value that electric energy meter measurespIt will often be less than or be much smaller than 15W.When stealing occurs,
