An inspection method for electric energy meter

Abstract

An inspection method for an electric energy meter. The frequency multiplication coefficient is set to n, and the frequency multiplication coefficient is written into the measurement module of the newly installed electric energy meter to perform measurement initialization operation, and the electric energy meter performs measurement according to the set frequency multiplication coefficient , to debug the error of the electric energy meter; set the frequency multiplication coefficient of the debugged electric energy meter to 1, and perform measurement initialization, and the electric energy meter will measure again according to the newly set frequency multiplication coefficient, and then perform aging settings on the electric energy meter Run the word; carry out functional inspection on the energy meter with the aging setting and running word completed, after the function inspection is completed; set the frequency multiplication coefficient to n, and use the above measurement method to perform a general error check on the electric energy meter, after the general inspection is completed; The frequency multiplication factor is set to 1, and the measurement is initialized; the factory settings are made for the electric energy meter; the factory inspection is carried out for the factory-set electric energy meter. The power is amplified by the frequency multiplication factor, which shortens the time for the electric energy meter to output a fixed energy, and greatly improves the production efficiency.

Description

Technical field[0001]The present invention relates to the field of electric energy, and more particularly to a test method of a power meter.Background technique[0002]In the production process of traditional electric energy meters, error debugging and error verification occupies most of the time, and severely restricts productivity. At present, the efficiency of energy meter error, error test, how to shorten product production cycle and energy consumption are bottleneck problems that are troubled by population production enterprises.[0003]Conventional energy meter error verification principle: Energy (W) = power (P) × time (T); often detects the energy meter using pulse detection methods, and the errors of conventional electrical capabilities use pulse method, that is, the power meter When the energy accumulates to a fixed value, the power table outputs a pulse, and the error verification desk body will acquire error by outputting the pulse of the venetical output pulse and the deskt...
