Detailed description of the invention
Fig. 1 is the method flow diagram of the method for the present invention.
Specific embodiment
It is as shown in Figure 1 the method flow diagram of the method for the present invention: the method for this quick investigation stealing provided by the invention,
Include the following steps:
S1. the single-phase meter electricity consumption data in area to be analyzed are obtained；
S2. in the electricity consumption data that step S1 is obtained, by firewire electric current less than 0 and the ratio of firewire electric current and neutral line current
The user that the absolute value of value is 1 is determined as that firewire-zero curve is reversely connected user, and such user is excluded stealing investigation range；
S3. in the electricity consumption data that step S1 is obtained, by neutral line current less than the first setting value (such as 0.1A) and zero
The absolute value of the ratio of line current and firewire electric current is that infinitely great user is determined as normal users, and such user is excluded
Range is checked in stealing；
S4. remaining user after the user excluded for step S2 and S3, calculates the neutral line current and firewire of each user
The absolute value of the ratio of electric current；
S5. the departure (preferably calculating standard deviation) for the absolute value that step S4 is obtained is sought, and by departure less than the
The user of two setting values (such as 0.1) checks user as emphasis；
S6. the emphasis obtained to step S5 checks user, obtains the history electricity consumption data of emphasis investigation user, and according to going through
History electricity consumption data repeats step S2~S4 and obtains the absolute value of the ratio of corresponding neutral line current and firewire electric current；Specially adopt
Absolute value is calculated with following steps:
A. the first 5 days history electricity consumption datas of emphasis investigation user are obtained；Wherein, history electricity consumption data is preferably that non-section is false
The first 5 days history electricity consumption datas of day；
B. it selectes a time point (, or) at preferably 7 points at 11 points at 15 points at 19 points, obtains emphasis investigation user in the time
First 5 days history electricity consumption datas of point；
C. the absolute value m of the ratio of neutral line current and firewire electric current is calculated using following formula:
Z in formulaiNeutral line current value for the user i-th day time point, AiFire of the user i-th day time point
Line current value；
If the absolute value that S7. step S6 is obtained is less than third setting value (such as 0.1), assert that the user uses for investigation
Family, and live stealing investigation is carried out to the user；Live stealing investigation can carry out live investigation using following rule:
Rule one: if scene is less than neutral line current using multimeter test firewire electric current, illustrate before meter inlet wire
There is shorting stub, can be found along house lead in investigation；
Rule two: whether the scene firewire electric current of multimeter test meter inlet wire is greater than the electric current or remote that meter is shown
The firewire electric current that Cheng Zhi is copied: there may be stealing is changed inside meter for explanation if firewire electric current is greater than neutral line current；
Rule three: if scene investigation is without exception, regarding as the disappearance of stealing scene or the provisional short circuit firewire of user, subsequent
The user is carried out to continue tracking.
By taking user 62049940738 as an example, August 4 zero firewire current ratios of time point on the 23rd are as follows:
The zero firewire current ratio of 1 user of table
| Time point | 7 | 11 | 15 | 19 |
| Firewire electric current | 0.795 | 2.741 | 2.562 | 0.515 |
| Neutral line current | 3.614 | 12.417 | 11.555 | 2.338 |
| Zero firewire ratio | 4.54 | 4.53 | 4.51 | 4.54 |
The deviation that zero firewire ratio can be calculated is 0.012；Therefore, for normal user, zero firewire electric current ratio
Value deviation it is minimum.So being judged by the value of zero firewire electric current ratio stealing, it can preferably judge to exist and steal
The possible user of electricity.
In addition, number of users is 800,000 families by taking one medium-sized city-level power supply company as an example, firewire electric current is less than neutral line current
The daily abnormal quantity of meter has more than 5000, and wherein most is different normally due to meter is total to zero curve causes, but the meter zero of zero curve altogether
Firewire ratio relatively disperses, irregular to follow, and total zero curve can be excluded by the deviation of the value of zero firewire electric current ratio in the present invention
Interference, it is more accurate to look into stealing user.
