Problems solved by technology

[0003] In the prior art, when applying current to the standard electric energy meter to detect the running accuracy of the tested electric energy meter, the electric energy produced by the standard electric energy meter corresponding to multiple different meter constants in the rising and falling stages of the current will be ignored. In order to eliminate this effect and make the detection results more accurate, the running time of the standard electric energy meter will be calculated through a long period of constant current, but this method leads to a long time of running and cannot completely eliminate the neglect of standard electric energy. The meter corresponds to the error caused by the electric quantity generated by multiple different meter constants in the rising and falling stages of the current

Abstract

The invention discloses a reading method, detection method, device and system of electric energy of electric energy meter, by obtaining various meter constants and corresponding pulses of the standard electric energy meter in the current constant section and non-constant section within the standard detection movement time From the constants of each meter and their corresponding pulse numbers, the running power of the standard electric energy meter within the standard detection time can be accurately obtained, which solves the problem of inaccurate reading of the standard electric energy meter in the prior art. To solve the technical problem that the counting time is too long, an accurate reading method, detection method, device and system for the counting power of an electric energy meter with short counting time are provided.

Description

technical field [0001] The invention relates to the technical field of grid power supply, in particular to a reading method, a detection method, a device and a system for electric energy of an electric energy meter. Background technique [0002] Electric energy has been applied to various fields in people's daily life and work, and has become an indispensable part of social development. People need electric energy meters to measure the electricity consumption of electric energy. The word time is too long. [0003] In the prior art, when applying current to the standard electric energy meter to detect the running accuracy of the tested electric energy meter, the electric energy produced by the standard electric energy meter corresponding to multiple different meter constants in the rising and falling stages of the current will be ignored. In order to eliminate this effect and make the detection results more accurate, the running time of the standard electric energy meter wil...
