Description
Technical Field
The utility model belongs to the technical field of the ammeter case, concretely relates to anti-electricity-theft ammeter case.
Background
With the development of economy, although electricity stealing behaviors are civilized behaviors, a certain amount of electricity stealing molecules are found out by means of site investigation, investigation and visit and the like, and the behaviors seriously affect the power supply order and cause adverse effects on the society.
Through the analysis of the electricity stealing behavior, one type is to open the cover of the electric energy meter and achieve the purpose of electricity stealing by changing the internal elements of the electric energy meter. In the checked illegal electricity stealing behaviors, the proportion of electricity stealing by opening the meter cover is up to more than 85 percent, and although the meter cover is a primary electricity stealing method, the principle of the electricity stealing method is simple and the technical content is not high.
The other type is that the electricity is stolen without opening the meter cover, the running environment of the electric energy meter is changed through a high-voltage electric field, a super-strong magnetic field and the like, so that the electric energy meter is halted and not measured, and the purpose of electricity stealing is achieved; and if malicious overload is adopted for electricity stealing without opening the meter cover, the running current far exceeds the rated current of the electric energy meter, so that the iron core of the electric energy meter is saturated magnetically, the generated magnetic field is not in direct proportion to the current intensity, and the purpose of electricity stealing is achieved. The electricity stealing method is hidden, the electric energy meter is recovered to be normal after running for a period of time, if the electric energy meter is really halted and does not run, the electricity stealing molecules recover the electric energy meter to be normal through a re-power transmission mode, equipment operation and maintenance personnel suspect that problems exist, the electric energy meter is taken down and checked, and all the electric energy meters recover to be normal and the problems cannot be found.
At present, the electric energy meter is networked, the operation data is transmitted back to a monitoring background in real time, the electricity stealing condition can be analyzed through big data, the big data analysis has certain limitation, only suspected electricity stealing users can be locked, and accurate judgment cannot be carried out.
The production of electric energy meters is standardized, and the internal elements cannot be changed randomly.

Along with the development requirement, the current intelligent electricity meter box for preventing electricity stealing comes into force.
The invention patent document with the publication number of CN 105759095B provides an intelligent electric energy meter box for preventing electricity stealing, electric leakage and personal electric shock, which comprises a box body, and a power supply unit, a control system, a strong magnetic monitoring unit, a strong electric interference monitoring unit, a zero-borrowing electricity stealing monitoring unit, a single-meter-position circuit breaker unit and a plurality of electric energy meters, which are arranged in the box body; the single-meter-position circuit breaker unit comprises a plurality of single-meter-position circuit breakers, and the electric energy meters correspond to the single-meter-position circuit breakers one to one. It should be noted that each electric energy meter station is correspondingly provided with a group of reed switches and a mutual inductor which are connected in series, and the strong electric shock monitoring and the strong magnetic monitoring of each electric energy meter are controlled in parallel by a control system. In addition, each mutual inductor is correspondingly connected with a strong-shock monitoring circuit; each electric energy meter position is provided with a reed switch for measuring strong magnetic interference and a mutual inductor strong electric interference, and the measuring and positioning are inaccurate due to the too close distance of the detecting elements. The electric meter box is designed with problems that after a certain user trips, the user can only inform equipment operation and maintenance personnel of switching on the site without a method, so that the power supply reliability of residents is seriously influenced, the distribution network has wide coverage, and great burden can be brought to the equipment operation and maintenance personnel. In addition, each electric energy meter station of the electric meter box is correspondingly provided with a set of strong magnetic monitoring unit. The strong magnetic monitoring unit at least comprises two reed switches with different directions, and the reed switches 7 with different directions are connected in series and then connected with a control system. The reed switch is interfered by strong magnetism, a switching value is output and transmitted to the control system, and the control system sends an instruction to the corresponding single-epitope circuit breaker. The reed switch corresponding to the electric energy meter is interfered by strong magnetism, the corresponding reed switch acts and is transmitted to the control system, and the control system sends an instruction to disconnect the single-meter-level circuit breaker corresponding to the electric energy meter, so that the power supply of the user is stopped. The user utilizes strong magnetic interference to steal the electricity, and strong electric field has certain limit, and the ammeter position is little in the ammeter case, and the incasement tongue tube distance is too close, can not accurate detection, may produce the erroneous judgement, causes to close on the user and can the mistake trip, seriously influences resident's power supply. The user utilizes the strong electric field interference to steal the electricity, and the strong electric field has certain range, and the electric energy meter position in the ammeter case is little, and mutual inductance coil distance is too close, can not accurately detect, probably produces the erroneous judgement, causes close on the user and can the mistake trip, influences the power supply reliability.

The electricity meter is used for measuring the electricity consumption of a user, and the result is used as an important basis for the electricity consumption of the user. The ammeter box is an important place for centralized arrangement and unified management of the ammeter and is widely applied to urban districts and markets of the modern society. At present, some power users or lawless persons in the society steal electric energy through various illegal means for the benefit of the users so as to achieve the purpose of paying no or less electric charges. Most of which are modified by changing the internal structure of the electric meter (for example, modifying the wiring, modifying the current coil of the short-circuit metering device, cutting off zero and stealing electricity, winding and passing metering, etc.). This act of stealing electricity involves not only personal and even national interests but also a number of security issues.
In order to prevent electric energy from being illegally stolen, ensure the safety of electricity utilization and eliminate the potential safety hazard of an electricity meter box in time, most of the electricity meter boxes adopt a disposable steel wire lock, a mechanical lock or an electromagnetic lock for safety protection so as to prevent a box body door from being illegally opened; most of the electric meter boxes are not provided with electric safety monitoring devices or adopt current transformers to carry out electric safety monitoring; the box door is illegally opened, and the state of the box door is monitored without a monitoring device or by adopting technologies such as infrared ray, electromagnetic monitoring and the like.
