Description
Technical field
The present invention relates to power supply facilities Inspection and maintenance technical fields more particularly to a kind of quick-mounting formula electricity stealing preventive metering to compare inspection
Survey instrument.
Background technique
In recent years, power supply enterprise and judicial authority constantly increase the delinquent inspection of stealing and hitting dynamics, but still
There are part individual and unit to continue to implement electricity stealing, converts flower in particular by the technological means of " high-tech content "
Sample escapes supervision.In the real work opposed electricity-stealing, pass through the investigation of historical data, it is found that some line losses are higher and electricity consumption is bent
The obvious abnormal route of line, but the comparison of metering on the spot in daily inspection was not found these routes there are problems.This
Remote control stealing is implemented often caused by someone, plays hide-and-seek, fights as a guerrilla with patrolman.
Remote control stealing is that illegally installation can be with the relay switch of wireless remotecontrol in the route of electric energy meter, benefit
The conducting and closure of relay switch can be controlled other than certain distance with special remote controler.As shown in Figure 1A, from electric energy meter
The phase line end of incoming cables private lead line of scale 103 is connected to the relay switch 101, then is connected back to by the relay switch 101
The phase line leading-out terminal of electric energy meter 103；The lawful wire drawn from electric energy meter 103 is connected to power load 102.Relay
Device switch 101 can power when being connected without electric energy meter 103 and to power load 102, and electric energy meter 103 is because short
Road and without counting；When patrolman carries out metering comparison on the spot, implement that disconnection relay can be remotely controlled after electricity filching person learns message
Switch 101, such electric energy meter 103 normally count, and the numerical value measured and patrolman are to measure Determination instrument institute
The reading of acquisition is equivalent, thus the presence that can not find stealing is compared by metering.In addition, the stealing mode of connection also having is adopted
The resistance for taking access one to be series at relay switch 101, in this way it is most of power be split and without electric energy meter
103, but still there is sub-fraction electric current to flow through electric energy meter；Stealing route is disconnected even if implementing electricity filching person and failing to be remotely controlled in time,
But since electric energy meter 103 remains counting, thus more it is not easy to be discovered by patrol officer, gimmick is more hidden.
Figure 1B is the remote control stealing wiring of another form, wherein is connected from the phase line end of incoming cables private lead line of electric energy meter 103
It is connected to the relay switch 101, then stealing load 104 is connected to by the relay switch 101, meanwhile, electric energy meter 103
The lawful wire of extraction is connected to normal power load 102；When relay switch 101 is connected, part power supply is split, no
Power through electric energy meter 103 to stealing load 104, electric energy meter 103 can only normal electricity consumption to power load 102 into
Row counts, thus has counted electricity consumption less；When patrolman carries out metering comparison on the spot, implement to be remotely controlled after electricity filching person learns message
Relay switch 101 only exists the normal electricity consumption of power load 102 at this time, thus can not find to steal by metering comparison
The presence of electricity.Even if disconnecting stealing route in addition, implementing electricity filching person and failing to be remotely controlled in time, but just common due to existing simultaneously
Electricity, electric energy meter 103 still carries out counting, thus the mode of connection of Figure 1B is still easily detected by inspection and finds that stealing is existing
As also belonging to hidden-type stealing gimmick.In addition, relay switch 101 and its private lead are often mounted on ammeter box back side seam
The concealed locations such as gap are simultaneously pretended, and are not overhauled, are difficult to find by unpacking.Generally have moreover, implementing remote control electricity filching person
There is stronger anti-inspection consciousness, for example found out the action rule of patrolman, or manpower is arranged to keep watch, very
As for the situation near installation camera monitoring ammeter box, opened once patrolman comes to be remotely controlled disconnection relay quickly
It closes.This has resulted in remote control stealing and has been easy to escape from daily inspection.
The main means of the electricity stealing of strike remote control at present are first is that reinforce the security performance of ammeter box, for example, by using high intensity
Hermetically sealed cabinet, once illegal unpack gives remote alarms etc.；Although however, improve the difficulty being transformed privately in this way,
Cost is significantly increased, and stealing implementer is often also proficient in the method for cracking related containment facility and continuing to implement transformation.
Second is that the analysis reinforced to electricity consumption data is checked, for example find the more previous records abnormal drop of the electricity consumption of certain electricity consumers
Not the case where electricity consumption and its production status of low or certain enterprises are not obviously inconsistent, but if to obtain positive evidence, also
Its route need to thoroughly be checked in the form of surprise check；This method, which generally requires, submits a report asking for public security organ's responding assistance,
Enforcement difficulty is larger, can only be for individual larger situations of suspicion really, it is impossible to long-term, frequently, predominately carried out.
As it can be seen that the case where how effectively discovery remote control stealing bring influences electric energy meter metering in daily inspection, is
Current problem in the urgent need to address.
