A fast detection device and method for electric energy meter

Abstract

The invention discloses an electric energy meter rapid detection device and a method thereof. The device comprises a processor unit, a photoelectric conversion unit which is connected with the processor unit, an input unit and a display unit. The photoelectric conversion unit captures the blinking of a predetermined number of pulse indication lamps of an electric energy meter which is externally connected with a standard AC electronic load, converts the blinking into a pulse signal, and sends the pulse signal to the processor unit. The input unit receives the standard pulse constant of the electric energy meter and the power of the standard AC electronic load which are inputted by a user and transmits the constant and the power to the processor unit. The processor unit calculates the theoretical measurement electricity quantity and the real measurement electricity quantity of the electric energy meter according to the pulse signal, the standard pulse constant of the electric energy meter and the power of the standard AC electronic load, further calculates an error percentage of the theoretical measurement electricity quantity and the real measurement electricity quantity, and outputs the error percentage to the display unit. The device can verify the measurement error of the electric energy meter and find an electric energy meter with a large measurement error.

Description

technical field [0001] The invention relates to the field of electric power equipment, in particular to a fast checking device and method for an electric energy meter for fast detection of an electronic electric energy meter. Background technique [0002] At present, power theft not only causes huge property losses to the country and power supply enterprises, but also seriously threatens the safety of power equipment and people. Therefore, power supply companies attach great importance to the fight against electricity theft. [0003] In addition to the frequent incidents of electricity theft by dedicated users, there are also frequent incidents of electricity theft by residential users. At present, power supply companies rely on clues provided by meter readers and residents to combat residential electricity theft, combined with the experience of full-time anti-electricity theft personnel, and impose fines after door-to-door inspections, proofs, and bills. This passive veri...

AI Technical Summary

Problems solved by technology

This kind of passive verification cannot actively discover a large number of hidden electricity theft incidents, and requires high experience of electricity inspectors

Furthermore, the number of resident users is huge, and it is time-consuming, laborious, difficult and inefficient to investigate and deal with only limited human resources.
