An electricity stealing-prevention electric energy metering device is provided. The electricity stealing-prevention electric energy metering device comprises two parts, wherein the first part is a power and effective value calculation circuit, and the second part comprises an energy accumulation and energy pulse generating circuit, a configurable input register, a first multiplexer and a second multiplexer; one input end of the first multiplexer is connected with one output end of the power and effective value calculation circuit and receives a current effective value outputted by the power and effective value calculation circuit; the other input end of the first multiplexer is connected with the output end of the configurable input register, such that output-to-input feedback is formed; the output end of the first multiplexer is connected with the configurable input register; an input end of the second multiplexer is connected with the other output end of the power and effective value calculation circuit so as to receive a power value outputted by the power and effective value calculation circuit; the other input end of the second multiplexer is connected with the output end of the configurable input register; and the output end of the second multiplexer is connected with the energy accumulation and energy pulse generating circuit.
Description
【Technical field】 [0001] The present invention relates to an electric energy metering device and a method for measuring electricity, in particular to an electric energy metering device for preventing zero wire from being cut off and a method for measuring electricity. 【Background technique】 [0002] Stealing electricity has seriously affected the safe operation and standardized management of the power grid. As a tool for electric energy billing, the energy meter must have the function of preventing electricity theft. [0003] Cutting the neutral wire is a widely used means of stealing electricity. In the electric energy meter, the electric energy metering chip uses the live line (L) as the ground, and the neutral line (N) as the power supply to obtain the energy required for the work of the electric energy metering chip, and obtains the energy required for electric energy measurement by dividing the voltage from the neutral line through a resistor network. Input signal for ...
