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

Embodiment Construction

[0038] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0039] Such as figure 1 Shown, a kind of reading method of standard watt-hour meter walking word electric quantity among the present invention, it comprises the following steps:

[0040] S1. Record each meter constant of the standard electric energy meter in the constant current segment and the non-constant current segment and the pulse number corresponding to each meter constant;

[0041] S2. According to each meter constant and the number of pulses corresponding to each meter constant, calculate the running quantity of the standard electric energy meter.

[0042] It obtains each meter constant and its corresponding pulse number in the constant current section and non-constant section of the standard electric energy meter within the standard detection running time, and can accurately obtain the standard ...

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...
