Description
Technical field
The present invention relates to power supply service technical field more particularly to a kind of quick check low-voltage customer multiplexing electric abnormality situations
System.
Background technique
In recent years, significant in national legal consciousness and legal knowledge as the extensive of national legal knowledge publicizes and popularize
While raising, some transgression for using electricity, stealing molecule, their legal consciousness is also significantly improved, although they have disobeyed method, he
Be good at catching the certain insufficient and weakness of power supply enterprise at work, with legal means, make oneself to escape due punishment；
According to not exclusively estimation, all parts of the country all have occurred a lot of because power supply enterprise's investigation breaks rules and regulations to cause with electricity stealing to some extent
Power supply dispute case；In the part case that power supply enterprise loses a lawsuit, because checking program and processing routine is illegal and evidence
Legitimacy and the cases of the factors such as accuracy is insufficient account for significant proportion.For this purpose, analysis is grasped, violating the regulations, stealing user is current
Situation, correctly use legal weapon, carry out power utility check work in accordance with the law, the severe transgression for using electricity and electricity stealing investigated and prosecuted seems outstanding
It is important.
The harm of stealing is as follows:
Stealing is very big to social harm, compromises the lawful right of power supply enterprise, state-owned assets is caused to be largely lost.As it can be seen that
Stealing is not only related to the economic interests of power supply enterprise, is also relate to electric power safety and stabilization supply of entire harmonious society etc. one
Series of tasks.
Electricity stealing endangers people's personal safety and power grid security.Electricity stealing harm is huge, gently then makes low tension
Gas facility is impaired, and local power is caused to interrupt；It is heavy then lead to technical power grid accident, in case of chain reaction, it is also possible to lead
Cause the serious consequence of large-area power-cuts.In addition, the electricity filching person desire for gain ticket heart easily causes electric shock injures and deaths by fair means or foul in stealing
Accident threatens other people personal safety.In recent years the person electric shock casualty accident caused by stealing because caused by stealing large area stop
Electricity, the fire incident that stealing is caused also frequently occur.
Stealing molecule tramples on social morality and the principle of good faith destroys the fair competition principle of market economy.They do not select hand
Section pursues unlawful interests, seriously destroys normally for electricity consumption order and social economic order, one side electricity filching person substantially reduces
Production cost causes the unfair competition of the same trade, has encroached on lawful operation person's interests；On the other hand at power supply peak
Section, user's peak load cutting of abiding by the law, some will also orderly allow electricity, and illegal user's Wuji steal the energy, trampleed on fair, public
Just and morality and justice.
Electricity stealing affects the harmony of society.In recent years, electricity stealing develops to high-tech from conventional method stealing and steals
Electricity develops to the stealing of organ, industrial enterprise from the illumination stealing of single household, develops to propagation stealing from the stealing of ordinary user
The professional stealing of technology and equipment, or even develop to clique's stealing.Stealing has become a kind of serious social effects of pollution, steals counter
In electricity work, the inspection personnel that opposes electricity-stealing is happened occasionally by abuse, event jointly attack, threatened, hit, this class behavior destroys normally
For electricity consumption order, also upset normal social economic order, affect society harmony.
Common electricity filching means are as follows:
Change metering device.Change the current coil of short-circuit metering device.It will with conducting wire usually inside or outside electric energy meter
Current coil is shorted, and more typical way is to use conducting wire or simultaneously the phase line input terminal and output end of connecting resistance insertion electric energy meter, is risen
To shunting function.It is shorted with conducting wire, and conductor resistance is no better than zero, most current will pass through from conducting wire is shorted, electric energy
The current coil of table causes electric energy meter to stall almost without electric current；And if when connecing the resistance less than current coil resistance value, electric current
Coil forms parallel circuit with simultaneously connecting resistance, and according to the shunting principle of parallel circuit, most of electric current will pass through from simultaneously connecting resistance,
Current coil only has low current to pass through, and causes electric energy meter slow-speed by a certain percentage, to reach stealing purpose.Such stealing mode
Referred to as undercurrent method stealing.
Disconnect connection piece.Off voltage joins piece or divider resistance of connecting on potential winding.Off voltage coil is exactly to make electricity
Crimping circle decompression causes ammeter not turn.Common methods are that the voltage plate of electric energy meter is unclamped, this method need not game clock envelope,
Belong to the stealing electricity method of lower level, novel ordinary electric meter is shorted connection piece inside ammeter.Second, opening one resistance of ammeter outer cover
It is serially connected on potential winding, institute's series resistor is entangled with insulating tape or insulating sleeve, has concealment, and principle is to play point
A part of voltage, is shared resistance both ends by pressure effect, is reduced potential winding both end voltage, is achieved the purpose that few quantity calculation.
Such mode is also referred to as under-voltage method stealing.
Tune connects zero firewire.Tune connects zero firewire stealing.This stealing electricity method is in advance by the fire of electric energy meter end of incoming cables, zero curve tune
It connects, according to the internal circuit configuration of electric energy meter, connecing the input of zero line side with output is shorted with joining piece, and therefore, stealing family can
Using the zero curve electricity consumption for setting or separately connecing certainly, and electric energy meter is because the current loop of not no opposite direction is by the current coil of electric energy meter,
Ammeter is caused to stall.This stealing electricity method must install back brake control switch indoors, make the zero curve by electric energy meter and set certainly
Ground wire separately connects zero curve and can freely control.But ground wire is set certainly can bring to the safety utilization of electric power of user and seriously threaten.
Stealing off zero.Stealing off zero.This stealing electricity method in advance must by the zero curve of electric energy meter end of incoming cables disconnect and by its
It is hidden.With adjusting connection stealing similar, requires separately to connect or set ground wire certainly, and installation back brake switch indoors.Disconnecting, ammeter is defeated
After entering zero curve, current coil still can be by electric current, and potential winding can lose voltage, and at this moment, the electricity consumption of stealing family, ammeter is will not
Metering.When ammeter rotation metering is thought at stealing family, zero potential can be reversely connected from ammeter zero line output end, i.e., separately connect zero curve or set certainly
Ground wire, potential winding obtain voltage, ammeter rotation.Second, the series resistor on the conducting wire of reversal connection zero potential, with under-voltage method phase
Seemingly, play the role of few quantity calculation.Such mode is also referred to as method off zero.
More gear changing.Its specific practice of counter gear is replaced, is the register replacement large capacity with low capacity electric energy meter
The register of electric energy meter, the practical electricity consumption of electricity ratio that the electric energy meter after being replaced goes out are reduced at double.For example, with 5 or 10 peaces
The Electric energy meter KWh counter of 1800r/kWh replaces the register of 10 or 20 peace 900r/kWh, due to the current coil and electricity of electric energy meter
Crimping circle does not become, then aluminium dish revolving speed is constant, but register had been replaced the practical electricity consumptions of rear former 900 turns of meters once, becomes and turns
1800 turns just once, the practical electricity consumption of metering electricity ratio reduces half to meter.The main points of this stealing electricity method are with same producer
Electric energy meter can exchange register, otherwise mechanical dimension can not correspond to.And the primary pass of stealing is exactly in this way
Open meter seal.But Electric meter seal used by present power supply department is all new-type seal, has good thief-proof electrical property
Energy.
Around more measuring.Around more metering device stealing around metering device stealing be mainly reflected in private and connect public line, this stealing
The feature of method maximum is easy to operate and compared with destructible stealing scene, when stealing family, which has been learnt, looks into electricity, will just be stolen in time
Electric wire is firmly ripped, and safety inspector is allowed to have no way of collecting evidence.Since the contact resistance that the private of stealing family connects conducting wire is all higher, along with naked
Dew or insulating tape close not tight and air and oxidation reaction occur, and further increase contact resistance, the meeting under the fuel factor of electric current
Generation arcing is stranded or even breaks.Such stealing mode can be brought to the safe operation of power circuit and seriously threaten.
In short, some people are greatly reduced in reality privately the electricity of short-circuit metering device in the electric current for being forced through electric energy meter
The phenomenon that streamline circle is modified, and the electric current of approach electric energy meter will be promoted to reduce causes current coil short circuit occur
Conducting wire is often inserted into, it will be able to the case where promoting current coil to be shorted, final energy in the both ends of electric energy meter by bad phenomenon
Enough realize the bad purpose of shunt current.Because conducting wire possesses smaller resistance, most electric currents will be promoted suitable from conducting wire
Benefit passes through, and the electric current so as to cause the current coil by electric energy meter can be effectively reduced, and will finally reach illegal and steal
The effect of electricity.The current mainly following three kinds of methods of the electricity filching means by changing electric current: short circuit current circuit, change circuit connect
Method and current loop is made to open a way.
In short, voltage connection piece is disconnected privately by some means or is connected on potential winding, it is ensured that Neng Goushi
Existing electric resistance partial pressure, can also effectively reduce the voltage on potential winding, generate not so as to the normal operation to electric energy meter
Benefit influences.It is then some necessary in its periphery covering if a string resistance preferably concatenated on potential winding
Safeguard measure those of can access effective safety guarantee in this way and greatly enhance its concealment, and connected electricity
Resistance is certain to effectively share portion voltage, will also reduce the voltage at potential winding both ends, can finally make electric energy meter
Quantity calculation be reduced, achieve the purpose that stealing.
The firewire and zero curve of electric energy meter end of incoming cables are effectively adjusted in short, zero firewire is adjusted, pass through dependence
The basic internal structure of electric energy meter, the output end and input terminal being shorted using connection piece, can be had using the zero curve electricity consumption set certainly
Effect avoids the detection of electric energy meter.Electric energy meter carrys out the current coil by electric energy meter due to lacking the current loop of opposite direction, will
Ammeter is set to stop operating.Back brake control switch to mainly be installed using this stealing electricity method indoors, it is ensured that be free to
It controls the zero curve of electric energy meter and sets ground wire certainly, however because needing from ground wire is set, this can bury no small security risk to user.
How could be effectively anti-electricity-theft.
For a long time, some units especially private enterprise takes various methods not using theft electric energy as profit means
Meter perhaps do not handed over achieving the purpose that or paid tariff less by few quantity calculation, is caused national electric energy to be largely lost, is lost surprising.This
The legitimate rights and interests for seriously compromising power supply enterprise, have upset normally for electricity consumption order, have seriously affected the development of electric utility,
And it brings and seriously threatens to safety utilization of electric power.But with the continuous upgrading of stealing technical intelligence, stealing main body is by original residence
Civilian family to enterprise, from life to manage, the development mutually colluded with by power supply enterprise's external-to-internal, or even have also appeared it is a collection of specially
" able person " of door research electric energy metering device, so that stealing electricity phenomenon still cannot effectively contain.Now with regard to electric energy metering device, come
Analyze common stealing mode and corresponding preventive technical measures.
Certain village's rural power work is in meter reading, it was found that client's electric energy meter refunds the event of some number together.Through site inspection,
Ammeter box and electric power electricity box lock are intact, and inside and outside portion's wiring also without any exception, excludes the possibility of the intentional stealing of client.
However also there is no problem through verifying for electric energy meter, still reverses after installation, rural power work have to move back the single-phase electric energy meter of the client
It runs out.It is helped to analyze reason for this purpose, village's rural power work finds the author.Confirmed by field assay, causes client's single-phase electricity
It can be there are two table the reason of reversing: first is that client's transgression for using electricity privately；Second is that the wiring of single-phase electric energy meter is lack of standardization, single-phase electric energy
The input terminal of table does not access phase line by regulation.Since the client is enabling the lighting load that three-phase and four-line electric energy meter is restaurant
When power supply, in order to scheme conveniently, not by it is single-phase illumination electric energy meter supply it is single-phase illumination master switch phase line and the neutral conductor simultaneously from
It illuminates and is extracted out on the connecting terminal of master switch upper end, but after only having extracted phase line out, and protected from the residual current of control noodle press
A phase line is drawn in shield switch upper end, is linked into electricity consumption in the former phase terminal of illumination master switch upper end.Privately due to the client
It relocates, so that significant changes have occurred in original lighting loop.The lighting loop of entire restaurant's electricity consumption is that electric current is by the visitor at this time
The terminal of the three-phase and four-line electric energy meter at family is flowed out through current coil from terminal, before accessing RCD, by client with interim company
Wiring is introduced on the left input terminal of single-phase illumination master switch.In this way, original of the lighting load electric current through illumination master switch is neutral
Line is connected on the connecting terminal of former leading-out wire of single-phase electric energy meter, into client's single-phase electric energy meter after back through this
The current coil of table, then flow back on the neutral conductor from the terminal that the original of single-phase electric energy meter taps into line, and and connect simultaneously in the neutral conductor
On three-phase and four-line electric energy meter the neutral conductor constitute a complete current supply circuit, ultimately form single-phase electric energy meter reversing show
As occurring.
Anti-theft electricity technology measure is as follows:
Pass through the analysis to above-mentioned several stealing modes, it can be seen that all stealing electricity methods nearly all directly will contact and change
Electric energy metering device can be only achieved the purpose of stealing.So reinforcing electric energy metering device technological transformation, keep mutual inductor, metering secondary
Circuit, electric energy meter, combined connection box and electricity box etc. are modified to totally enclosed type metering by the metering of pervious open type, are to prevent stealing
Most efficient method.
To resident, using concentrating meter mounting box or totally-enclosed electricity box, i.e. line inlet pipe, pipe inlet, case is locked and seal
Method makes one, table separation, allows user that can not touch electric energy meter and secondary line.
To low for low user of the meter with TA, when transformation, carries out electric energy metering device batch meter or cabinet primary totally-enclosed anti-
Only stealing.
Original electromechanical electric energy meter is replaced, full electronic multifunctional electric energy meter of new generation is used.Because of the more function of full electronic
Can electric energy meter have be unable to upside-down mounting, can not change constant, decompression, defluidization record and current imbalance record, negative phase sequence record,
If the logouts anti-stealing electricity function such as table.
