Problems solved by technology
[0004] The purpose of the present invention is to provide an anti-stealing single-phase smart energy meter to solve the problem that the core of the current energy meter proposed in the background technology is in the aspect of electricity measurement, and the accuracy and reliability of electricity metering have been done very well. Good, but insufficient attention is paid to the prevention of electricity theft, so many electricity theft behaviors in the actual operation process cannot be judged by the electric energy meter, and there are large flaws, and the electric energy meter has flaws of varying degrees in heat dissipation and fixing direction , if the installation is relatively rigid, the meter body is often unable to perfectly match the meter box, and the meter body is often damaged due to excessive temperature

Embodiment 1
[0036] The meter can be matched with dual relays to control the live wire and neutral wire circuit respectively, cut off the user circuit through the relay, realize the function of anti-stealing electricity, increase the live wire current and neutral wire current comparison function and the corresponding event recording function;
[0037] in:
[0038] 1.
[0039] 1L / N current difference >= 10%, the relay will trip with a delay of 60s, and the LCD will prompt error ERR-22 The difference 10% can be set: If FF0400F5 xx% is set to 0, this function will not be judged
[0040] Program judgment processing:
[0041] 1) if A>=B: (A-B) / B*100%>=10%
[0042] 2) if B>=A: (B-A) / A*100%>=10%
[0043] 3) if A=0, B! =0: Default is >=10%
[0044] 4) if B=0, A! =0: Default is >=10%
[0045] 2L / N current difference event record data identification: FF0400F7.
[0046] Event records include: instantaneous voltage, instantaneous current live wire and neutral wire, current total electric energ...

The invention relates to an anti-stealing single-phase intelligent electric energy meter, which comprises a meter body and a mounting room. Side joint slideways are opened in both the left and right ends of the front wall of the meter body, auxiliary maintenance mechanisms are mounted at both the left and right ends of the meter body,edge slots are formed in both the left and right ends of the bottom of the meter body, the inner ends of the edge slotsare connected with cooling fins, and the inner sides of the edge slots are connected with transverselinkage holes; and side edge auxiliary positioning mechanisms are mounted on both the outer sides ofthe left and right ends of the bottom end of the meter body, and a top cover is mounted at the top end of the meter body. The anti-stealing single-phase intelligent electric energy meter has the beneficial effects that the anti-stealing single-phase intelligent electric energy meter is provided with connecting sliding blocks, connecting sliding grooves, and connecting spring columns, positioning parts of the side edge auxiliary positioning mechanismscan be slidably adjusted conveniently by using the connecting sliding blocks, the connecting sliding grooves, and the connecting spring columns, so that the positioning positionsare flexibly adjusted, reasonably selection of the mounting position of an electric meter is convenient for a user, and pairing using of the electric meter anda meter box is facilitated.
Description
technical field [0001] The invention relates to the technical field of electric energy meters, in particular to an anti-stealing single-phase intelligent electric energy meter. Background technique [0002] The smart meter is the smart terminal of the smart grid. It is no longer an electric energy meter in the traditional sense. In addition to the basic power consumption measurement function of the traditional electric energy meter, the smart meter also has two-way multiple functions in order to adapt to the use of smart grid and new energy. Intelligent functions such as rate metering function, user terminal control function, two-way data communication function of multiple data transmission modes, and anti-theft function, smart meters represent the development direction of future energy-saving smart grid end-user intelligent terminals. [0003] At present, the core of the electric energy meter is in the aspect of electricity metering. It has done a good job in the accuracy a...
