Abstract

The invention discloses an electric energy meter calibration system, and relates to a single-phase or three-phase electric energy meter calibration system. At present, an automatic calibration system is not provided during calibration of an electric energy meter, a plurality of groups of manual detection platforms are mainly adopted, and the method has the defects of high labor intensity, manual error existence, slow comprehensive calibration speed and the like. The electric energy meter calibration system comprises a plurality of calibration units, a main transmission line and a calibration management system, wherein the calibration units are used for automatically calibrating the electric energy meter; the main transmission line is used for connecting the calibration units; the calibration management system is used for coordinating the operation of the calibration units; the main transmission line consists of an upper transmission line and a lower transmission line; the upper transmission line is used for transmitting a meter box equipped with an electric energy meter to be tested to the calibration units; and the lower transmission line is used for transmitting a meter box equipped with a tested electric energy meter to a warehouse. The technical scheme has the advantages of high working efficiency, low production cost, low labor intensity, high safety and high quality.

Description

Technical field [0001] The invention relates to a single-phase and three-phase electric energy meter verification system. Background technique [0002] At present, there is no automatic verification system in the verification process of the electric energy meter, which is mainly composed of multiple sets of manual test benches. This method has the disadvantages of high labor intensity, manual errors, and slow overall verification speed. Summary of the invention [0003] The technical problem to be solved and the technical task proposed by the present invention are to improve the existing technical scheme and provide an electric energy meter verification system to achieve the purpose of fully automatic verification and effectively improve efficiency and verification accuracy. To this end, the present invention adopts the following technical solutions. [0004] The electric energy meter verification system is characterized in that it includes a plurality of verification units for aut...
