Problems solved by technology

In view of the above phenomenon, we have encountered some practical difficulties in the actual anti-theft maintenance: for the phenomenon of external illegal wiring and external interference, the on-site personnel can find and remove it intuitively, but for the internal modification of the smart energy meter, it cannot be accurately Effective identification, because now it is easy to obtain counterfeit sealed lead seals. After the electricity thief opens the cover and reinstalls the lead seal, it is impossible to recognize that the watch has been opened and changed from the appearance.

Embodiment 1

[0047] refer to figure 1 , when the single-phase smart meter occurs table cover button 6-2 (such as image 3 When shown) is interrupted, the anti-stealing processing method of the present invention is used to perform anti-stealing processing on the single-phase smart meter, and the anti-stealing processing method includes the following steps.

[0048] S1. Monitor whether the state change time of the cover button 6-2 of the single-phase smart meter reaches 800ms, if yes, go to step S2.

[0049] S2. Judging whether the single-phase smart meter is in a power-off state, if yes, go to step S3.

[0050] S3. Judging whether it is the first time that the single-phase smart meter has opened and closed a cover event after power-off, if yes, proceed to step S4, otherwise proceed to step S7.

[0051] S4. Judging whether the current single-phase smart meter is an action of opening the cover, if yes, go to steps S5 and S6.

[0052] S5. Record the uncapping event and eliminate the status wo...

Embodiment 2

[0082] Using the anti-stealing processing method of the single-phase smart meter described in Embodiment 1, while accurately detecting the electricity theft of the single-phase smart meter, it may also include the step of actively reporting the electricity theft behavior to the master station. Notify the main station that the single-phase smart meter has been opened and stolen, and special personnel are required to come to check and deal with it. At the same time, the electric alarm lamp on the local display screen of the single-phase smart meter that has been stolen is lighted and flashed, so that the anti-stealing special personnel can simply identify that the single-phase smart meter has been transformed by stealing electricity. surface. And this time, the single-phase smart meter that has been stolen refuses to execute the general relay 5-2 closing and energizing command, and does not energize the user. However, this anti-stealing processing method leaves a special comman...

Embodiment 3

[0084] In order to further prevent electricity theft from occurring in the single-phase smart meter, in addition to loading the anti-theft treatment method described in Embodiment 1 on the single-phase smart meter, hardware changes can also be made to the single-phase smart meter. That is, the connection mode of the relay 5-2 in the single-phase smart meter is changed.

[0085] see figure 2 At present, most of the industry still uses the traditional method of screwing to install the existing relays on the No. 1 and No. 2 terminals in the single-phase smart meter. In this traditional connection method, the electricity thief can unscrew the internal screws of the No. 1 terminal and the No. 2 terminal, and then additionally screw on the copper wire to shunt and steal electricity. In order to solve this shortcoming, the present invention installs the relay 5-2 on the No. 1 terminal and the No. 2 terminal by impact crimping to form a whole. In this way, electricity thieves canno...

Abstract

The invention discloses an electricity larceny prevention handling method and device of a single-phase intelligent meter. The electricity larceny prevention handling method is used for conducting electricity larceny prevention handling when meter cover key disconnection of the single-phase intelligent meter occurs. By detecting whether the single-phase intelligent meter is in a powering-down or electricity-larceny state, it is effectively judged whether the single-phase intelligent meter is in the electricity-larceny state or not, the problem is effectively solved that at present, it cannot beidentified from the appearance that the single-phase intelligent meter is uncovered or not and the inside of the single-phase intelligent meter is changed or not. A meter cover key is arranged to besunken, so that the effectiveness of meter cover key state change is ensured. A relay is installed on a terminal 1 and a terminal 2 in an impacting press-connection way to form a whole so that an electricity larceny person cannot effectively install a shunting copper wire on the terminal 1 and the terminal 2 in the single-phase intelligent meter and accordingly cannot perform shunted electricity larceny, and the electricity larceny phenomenon of the single-phase intelligent meter is more effectively avoided.

Description

technical field [0001] The invention relates to the technical field of electrical instrument manufacturing, in particular to an anti-stealing treatment method for a single-phase smart meter and an anti-stealing treatment device thereof. Background technique [0002] With the continuous development of science and technology, electric power resources are the most important form of energy in the current social development. Through the continuous application of high and new technologies, improving the reliability of power grid operation is the constant goal of electric power work. As an important basic technology in the current grid intelligence, smart meters help to achieve more effective power resource management, and have been widely used in all levels of social development. The use of smart energy meters can accurately calculate the power consumption of users, and at the same time can make the information of power companies transparent, giving the majority of power customers...
