[0056] The control unit 1 includes an intelligent controller, the intelligent controller includes an MCU, a display, and a keyboard, and the display and the keyboard are respectively connected to the MCU;

[0057] The anti-stealing unit 2 includes a transformer connected in series on the meter body, which is used to change a voltage different from the load operating voltage into the load operating voltage; a relay is provided at the output end of the transformer, and the control end of the relay is connected to the MCU ;

[0058] The voltage detection unit 3 includes two voltage sensors arranged on the primary and secondary sides of the transformer; the voltage sensor is electrically connected to the MCU, so that the MCU collects voltages on both sides of the transformer;

[0059] The voltage regulating ...

specific Embodiment 3

[0064] According to the control system of the intelligent anti-theft electric meter of specific embodiment 2, its control method:

[0065] (1) After the ammeter is connected to the power grid, the voltage sensor detects the voltage on the primary and secondary sides of the transformer at the same time;

[0066] (2) The MCU collects the analog voltage signal detected by the voltage sensor and converts it into a digital voltage signal for storage;

[0067] (3) At an interval of 60ms, the MCU collects, converts, and stores the voltage on the primary and secondary sides of the transformer again;

[0068] (4) After the MCU stores 8 digital voltage signals, the MCU extracts the stored digital voltage signals to calculate the average voltage, and at the same time calculates the maximum variation range of the voltage; if the maximum variation range of the voltage is not greater than the maximum variation range value pre-stored in the MCU, Then record the maximum variation range and a...

Abstract

The invention relates to an intelligent antitheft electric meter, and belongs to the field of electrical equipment. The electric meter comprises an electric meter body, a transformer, an intelligent controller, and a voltage regulator. The electric meter body is in series connection with the transformer, and the voltage regulator disposed on the transformer is used for controlling the output voltage of the transformer. The primary and secondary sides of the transformer are respectively provided with a voltage sensor, and the voltage sensors are connected with the intelligent controller. An input voltage of the transformer is different from the working voltage of a load, and the output voltage is the working voltage of the load. The transformer is in series connection with the electric meter body, and then can convert a high-voltage into a low voltage, thereby facilitating the high-voltage transmission of a cable, facilitating the saving of electric energy, and reducing the circuit loss of a transmission line. In addition, the above structure can supply a voltage, which cannot be directly used by common electrical equipment, at the primary side of the transformer, can avoid electricity stealing, and improves the safety of a power grid. The electric meter can guarantee that the load cannot be directly connected to an input end of the electric meter for direct use, and avoids electricity stealing.

Description

technical field [0001] The invention relates to an intelligent anti-theft electric meter, which belongs to the field of electrical equipment. Background technique [0002] An electric energy meter is an instrument used to measure electric energy, also known as an electric meter, a fire meter, or a kilowatt-hour meter, and refers to an instrument for measuring various electrical quantities. Current meter in use. The current coil inside the meter is short-circuited on the lead wire outside the meter to achieve the cheating effect of using electricity without running characters or less characters. This method of stealing electricity is very simple, that is, use a small section of wire outside the meter to short-circuit the two connectors of the meter to achieve the purpose. This method does not destroy the lead seal, the case, does not need to be connected to the open wire, and is easy to camouflage and emergency destruction, so it is adopted by many users. This is a serious...
