Description
Technical field
The present invention relates to power supply facilities Inspection and maintenance technical field, more particularly, to a kind of quick-mounting formula electricity stealing preventive metering compares to be examined
Survey instrument.
Background technology
In recent years, power supply enterprise and judicial authority constantly increase to the delinquent inspection of stealing and hitting dynamics, but still
There is partly personal and unit continuation enforcement electricity filching behavior, the technological means in particular by " high-tech content " to convert flower
Sample, escapes supervision.In the real work opposed electricity-stealing, by the investigation of historical data it is found that some line losses are higher and electricity consumption is bent
The substantially abnormal circuit of line, but the metering on the spot in daily inspection compares and was not found these circuits existing problems.This
Implement remote control stealing often caused by someone, with patrolman's hide-and-seek, fight as a guerrilla.
Remote control stealing is that illegal installation can be with radio controlled relay switch in the middle of the circuit of electric energy meter, profit
With special remote control can beyond certain distance control relay switch conducting and closure.As shown in Figure 1A, from electric energy meter
The phase line end of incoming cables private lead line of scale 103 connects to this relay switch 101, then is connected back to by this relay switch 101
The phase line leading-out terminal of electric energy meter 103；The lawful wire drawn from electric energy meter 103 connects to power load 102.Relay
Without electric energy meter 103, power load 102 can be powered during device switch 101 conducting, electric energy meter 103 is because short
Road and do not count；When patrolman is measured comparison on the spot, implement remote control to disconnect relay after electricity filching person learns message
Switch 101, such electric energy meter 103 normally counts, and measures the numerical value obtaining with patrolman to measure Determination instrument institute
The reading obtaining is all equivalent, thus relies on metering to compare the presence that cannot find stealing.In addition, the stealing mode of connection also having is adopted
Take one resistance being series at relay switch 101 of access, so most of power supply be split and without electric energy meter
103, but still have sub-fraction electric current to flow through electric energy meter；Disconnect stealing circuit even if implementing electricity filching person and failing timely remote control,
But because 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, from the phase line end of incoming cables of electric energy meter 103 private lead line even
It is connected to this relay switch 101, then connected to stealing load 104, meanwhile, electric energy meter 103 by this relay switch 101
The lawful wire drawn connects to normal power load 102；When relay switch 101 turns on, part power supply is split, no
Power to stealing load 104 through electric energy meter 103, electric energy meter 103 can only enter to the normal electricity consumption of power load 102
Row counts, thus has counted electricity consumption less；When patrolman is measured comparison on the spot, implementing can remote control after electricity filching person learns message
Relay switch 101, now only exists the normal electricity consumption of power load 102, thus relies on metering comparison cannot find to steal
The presence of electricity.Even if disconnect stealing circuit in addition, implementing electricity filching person and failing timely remote control, but just conventional 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 patrolling and examining and finds that stealing is existing
As falling within hidden-type stealing gimmick.In addition, relay switch 101 and its private lead are often arranged on ammeter box back side seam
The concealed locations such as gap are simultaneously pretended, and do not pass through to devan and overhaul, are difficult to find.And, implement remote control electricity filching person and typically have
There is stronger anti-inspection consciousness, such as found out the action rule of patrolman, or arranged staff to be kept watch, very
As for situation about installing near camera supervision ammeter box, once patrolman comes to open remote control disconnection relay quickly
Close.This has resulted in remote control stealing and has been easy to escape from daily inspection.
The Main Means one hitting remote control electricity filching behavior at present are the security performances strengthening ammeter box, for example with high intensity
Hermetically sealed casing, once illegally unpack give remote alarms etc.；Although however, so improving the difficulty privately transformed,
Significantly increase cost, and stealing implementer is often also proficient in the method cracking related containment facility and continuing to implement transformation.
Two is to strengthen the analysis investigation to electricity consumption data, such as finds the power consumption more conventional records abnormal fall of some electricity consumers
Low, or the situation that the power consumption of some enterprises is not substantially inconsistent with its production status, but if positive evidence to be obtained, then also
In the form of surprise check, its circuit thoroughly need to be investigated；This method generally requires submits a report asking for public security organ's responding assistance,
Enforcement difficulty is larger, can only for individually really the larger situation of suspicion it is impossible to long-term, frequently, predominately carried out.
It can be seen that, in the middle of daily inspection, how effectively to find the situation of the impact electric energy meter metering that remote control stealing brings, be
Currently problem in the urgent need to address.
